You're probably going to be more sensitive to the cold than the average Mainer, so I'd recommend layering. You'll want sweater/sweatshirts, long-sleeved shirts, a lighter coat, a heavier winter coat (think a down-type coat), as well as gloves, scarves, and hats. Hats are something that a lot of people skip but they don't realize how much warmer you are wearing one.
Also, you want good waterproof winter boots. Wool socks will probably be a good investment too. Having cold or wet feet during the winter is the WORST.
To save money, you can find all that kind of stuff at the Goodwill or Salvation Army. Buying all of it new gets really expensive and you can find good quality stuff at thrift stores.
Also, I recommend keeping some of these on hand (lol puns): https://www.amazon.com/HotHands-Hand-Warmers-Odorless-Activated/dp/B0007ZF4OA. They're little packets that warm up and stay warm for a long time. I keep them in my pockets and shove my hands in there when they get really cold.
I live in Canada and have struggled with this every winter of my damn life lol. For what it’s worth, the best solution I’ve found is to buy big boxes of these hand warmers (https://www.amazon.com/HotHands-Hand-Warmers-Odorless-Activated/dp/B0007ZF4OA) at costco, and tuck one in each glove on the inside of my wrist. It makes a huge difference and does keep my fingers warm. I also often tuck one in my boots on the inside of my ankle when it’s super cold and my toes stay warm. It’s wasteful however, since the warmers are disposable. If someone has a better solution for actual heated gloves that work as well I also want to know!
They also have some you can put in your shoes.
Ah you’re in the same boat as one of my friends! She’s from South Asia and hasn’t experienced the cold yet. Here’s some of the tips I can give you with dressing warm and comfortable.
Thermal leggings under your pants! (Not sure what your gender is but we all get cold so don’t let the word “leggings” scare you off- extra points if there’s fleece inside)
hot hands from Canadian tire or Amazon! (If you’re going to be outside for an extended period of time I recommend sticking these bad boys in your pocket)
water resistant footwear. (Snow melts when you bring your shoes inside, slush is everywhere during random points, always wear resistant footwear because you’ll have wet shoes otherwise)
I’ll try to update this later if I think of anything
I'm in Ohio and we've prepped for the power going off during cold weather.
We bought a stash of mylar emergency blankets and HotHands.
Look at camping/hunting gear for cold climates. Gloves/mittens, wool socks, thermal underwear. We haven't bought them yet but we're considering buying some sleeping bags. We bought a couple small camping stoves in case we want to cook, one uses wood the other fuel cubes
If you have municipal water you need to let your faucets drip lest your pipes freeze. Don't believe anyone who tells you this doesn't work. I worked in multifamily housing for over 20 years. Due to a design flaw in our buildings the pipes would freeze and burst once the temperature dropped below 10. We had to constantly badger our residents to let the faucets trickle and not turn off their heat if they were going out of town. Buy some RV antifreeze to add to your toilet.
We bought a small solar generator whe are going to use to charge kindles, phones and emergency lights.
We rent so we can't use a fuel generator. It would also be a violation of our lease to have propane or the like in our home. As far as cooking goes, I have a gas range I'm told will work if I light the burner with a match. I plan to eat mostly sandwiches, crackers and cheese if the power is off.
If you can try to keep everyone in a single room. Close the doors to room you aren't using. Keep bathroom doors open to help keep the pipes warm. Block the bottom of the doors with blankets or towels to keep you heat from escaping. Put blankets or towels on your window sills too. It's common up here for people to put plastic over their windows once the temperature drops. They sell kits for it here but you can also use the rolls of plastic painters use for drop cloths.
That's a possibility. We have three, and didn't have a good way to use them. We also had three cats in the car, and kept it warm for everyone to begin with. The chemical pads were mainly supplemental. We used these.
HotHands Hand Warmers - Long... https://www.amazon.com/dp/B0007ZF4OA?ref=ppx_pop_mob_ap_share
We just finished stocking up for winter with the possible of a prolonged power outage.
We have:
30 mylar emergency blankets.
40 packs of Hothands
We have 3 months of food of various types.
2 small camp stoves, 1 that uses fuel tabs, one that uses kindling.
30 day supply of bottle water for 2 people. We also have 2 water BOBs to use in the bathtubs.
RV antifreeze to put in the toilets and pipes should it get cold enough for the pipes to freeze.
No water body wash and shampoo plus wipes.
We have a year's supply of toilet paper.
I’m not sure if you’ve heard of these, but you can get little hand and feet warmers to stick in mitts or in your shoes. These save my life in Canadian winters! Here’s an Amazon linknk just so you can see what they look like. I usually find them at outdoorsy stores (in smaller packs too)
Put some hot hands in your gloves and you’ll be able to poach an egg in your mitts while riding the lift.
I know my guy seems to adjust to it after a while. This morning it was about -6 with the windchill, so I was expecting a quick around the block and back home. Instead we were out for an hour. Last night, it was about 5 with the windchill, and after 30 minutes at the park he was ready to go home. I'm never quite sure what he will decide each day, so I make sure to be prepared. Oh, and hot hands in your gloves are life savers! If you stick them in a ziplock bag after use, you can get way more than the 10 hours out of them too.
I put these in everyone I play outside and it is cold. Feet are toasty!
If you have the trouble finding heated gloves you like, my wife swears by hot paws for working outside in the cold.
Buy a package of handwarmers. My wife and I use them for our longer winter walks.
They're better with mittens than gloves, but if you keep one in your palm it'll help, though the tips of your fringers will freeze.
Toothbrushes, small flashlights, heated hand packs
Gloves
If you live in a place that snows often, buy quality snow tires. Having good traction snow tires on a front wheel drive car, is better than a vehicle that has All Wheel Drive (AWD) or 4 Wheel Drive with summer or all season tires.
People generally buy winter tires and use them during the winter. Once spring comes around, they swap out their tires for different ones and keep the winter tires in storage.
You'll also need a windshield brush/scrapper to remove all of the snow from your car. I mean all of it, this includes the roof, rear windshield, hood, etc. Leaving snow on your car while you drive is a hazard to you and other drives as snow can fly off and hit the car behind you. Or the snow can melt on the roof and when you brake, the whole blanket of snow will cover the front windshield.
You'll also want cat litter or floor mats in case you get stuck in some snow. Simply sprinkle or place the mats under the stuck tires and easy your way out.
Here a list of other things that you may find useful: * Shovel * Blanket * Hand warmers * Flashlight
As for your car, it's a good idea to check the condition of your coolant/antifreeze. It should be a 50/50 mix, 50% coolant and 50% water. Some auto parts stores can test your coolant using a coolant tester to see what the concentrations are.
Another good idea is to have your car's undercarriage washed or sprayed down with water around once a week. This is because some places put salt on the roads to help melt ice. Unfortunately for you, the salt can corrode and rust the chassis and body of your car if you do not remove it.
I use hand warmers on one side of the tank. I personnaly put it in a small box to stop my critters from touching it directly.
I live in Quebec and blackout are more frequent here.
I've started using these in my gloves for running near or below freezing.
https://www.amazon.com/dp/B0007ZF4OA/ref=cm_sw_r_cp_awdb_imm_t1_QT476GSSX8ZE53GZDDFX
I've tried lots of gloves and really warm but still thin enough to use your hands is not really possible I think. 🙁
When it's really cold, I stuff HotHands hand warmers in my socks and gloves during the night. I find that if I can keep my extremities warm, the rest of me stays warm, too. They get so hot that they can burn you, so it's good to have a base layer (like a sock) before you put on another pair of socks to keep the heat in place.
They're much cheaper online than they are in a store. I buy them in bulk on Amazon.
Do you do any body exercises ? Try to work out your heart and do 5 min breaks each hour by exercising your wrists.
On the other hand there are hand warmers that competitive gamers use before matches. Like these amazon link
these ones look good! hot hands brand is the same one I see all over the place
Not sure if they come in smaller packs but that brand is all over the place except when I need to buy them lol.
I bought a pack of handwarmers off amazon (~$25 for 40 pairs, but you can cut in half so its actually 80) and will keep them in the trunk. Hasn't gotten cold enough in Boston to need to use yet though. But, I think they would get warm enough to unfreeze the handles & trim areas w/o damaging anything.
Hot water bottle wrapped in a towel. Or if you want to get really fancy you can buy those hand warmer thingies
ALWAYS HAVE THESE, always have extra, always help the producer when they are cold. you will be remembered lol.
A lot of women keep fingerless gloves at their desks, and then you could stash some of these in the gloves (also stashable in pockets, and they make ones that go in your shoes too).
I would look for wool dresses/skirts/blazers that would probably keep you warmer. Also layers (like have a blouse, a sweater, and a blazer, also meaning you can peel layers off if need be). In Winter I've worn ankle length skirts with fleece lined leggings and knee socks underneath. Albeit this is because it was effing cold and I rode the bus... But yeah, I would also look for pieces just made with thicker material in general. Like fast fashion pieces tend to be thin, higher quality pieces tend to be made out of thicker fabric (at least that I've seen) and that might work better for you.
They make a product called Hot Hands - it's a hand warmer that is a packet filled with powder that activates and generates heat when exposed to air. It's made for camping in cold places. Pick some up at the store or on Amazon and keep them in your pocket. They last a few hours.
You may not want to get 40 pairs right away, but here's a link
HotHands Hand Warmers (40 pairs) https://www.amazon.com/dp/B0007ZF4OA/ref=cm_sw_r_awd_4oXLvbPB04PPP
I don't think it is necessary to give a gift card for a lowkey care package, but if you know they are struggling financially or they have a favorite grocery store or clothing shop then it sounds like a great idea. You can utilize things like Groupon, Amazon home services for cleaning and home repairs, BlueApron or equivalent food prep boxes. I have heard that many people like those type of subscription boxes.
My personal favorite care package goodies are shared below. I would wrap a pretty scarf around a small bundle of goodies. And to make it all pretty, I would pin artificial flowers and a thoughtful card to the front.
Nature's Approach Aromatherapy Neck Wrap Herbal Pack, Celestial Indigo
But in terms of "adulting" you could give them Groupon vouchers for cooking classes or yoga/meditation. But if they are strapped for cash, I would definitely include a gift card to their local grocery store.
For point number 4 on disposable hand warmers, have you tried Hot Hands? https://www.amazon.com/HotHands-Hand-Warmers-Odorless-Activated/dp/B0007ZF4OA/
They genuinely last for 10hrs+ and don't generate any moisture by using some sort of Iron dust rusting mechanism. We put them on the inner palm side of the gloves so it heats the blood heading out towards the fingers. I stopped needing to use them after buying Sabot Heat elec gloves for $69 on Amazon which give me many hrs of heat with finger dexterity but admittedly I havnt tried them in extreme minus temperatures it looks like you have in your pictures.
$28 for 40 packs... twenty pairs. Oxygen activated heat packs. Put them between your jacket and your shirt. When they are done, they are disposable.
I've done a lot of location in Alaska, and handwarmers for sure.
The secret to staying warm is not getting cold. : )
Once you are cold, life becomes hard.
Consider the small disposables like <https://www.amazon.com/dp/B0007ZF4OA?ref=nb_sb_ss_w_as-reorder-t1_ypp_rep_k0_1_23&amp=&crid=5DEMOQZ7KCQF&amp=&sprefix=disposable+hand+warmers>
These are small enough to place at the arch of the feet, between the sock and the shoe bed, another pair in the palms of the hands, between (fingerless) glove liner and glove shell. Another pair can go at kidney level on back, held with ace bandage.
These disposables are air activated, between uses, store them in ziplocks and squeeze the air out....I've used the same pair for weeks this way.
.
This is a potentally dangerous situation.
Consider appointing someone to keep an eye on those who must focus intensley on their work.
.
All the best, stay warm out there!

Canadian here, coming to share what's gotten me through -40°C and beyond:
First and foremost, you need warm socks. I'm sure you've heard people praise merino wool, but if you don't wear wool, Heat Holders are a good alternative. You could get the thin ones as well as the thick and layer them up. Wear those with shoes that will keep you dry. If you're layering socks, you might want to size up for the extra socks.
Layers for sure. You can get thermals, but I often just wear my Lululemons and a regular bamboo long sleeve as my base layers. On top of that, you can wear a thick cardigan or fleece pants that don't let the wind through- (Something like this or just thick jeans or wool dress pants. You could also layer multiple leggings over one another. I do this with tall boots, and wear dresses in -30, but maybe that's just me. Your pants and socks should cover your ankles and leave no exposed skin. As a tall gal the cropped jean trend was a recipe for frostbite.
Your coat: Puffers are not waterproof, and they also aren't great for strong winds. Should you get something waterproof instead? No, you should get something waterproof AS WELL. I recommend a 3-in-1 coat, which can be worn as a puffer or fleece, raincoat, or both for full warmth. If you layer well you won't need to spend as much on a coat. Mine is Joe Fresh, I literally bought it at the grocery store, but here's a similar one.
Extras: gloves, scarf or neck warmer, hat. You'll need all of these. If it's super windy you won't want any skin exposed other than your eyes.
Cherry on top; I'm not sure if it's legal to travel with these, but if you can bring some hand warmers or get them at your destination, do so. People working labour jobs here swear by them to keep them working outside in -40 °C (and sometimes colder with windchill).
Avoid cotton where you can. It's absolutely useless in the cold. If wool is an option, wear it. Otherwise fleece is a close second. Bamboo is great for wicking, as are some of the activewear syntheticcs. Everyone loves to hate on acrylic but it's actually really warm for cardigans, socks and mittens. It does fall apart quickly though.
You may want to bring a foam roller, tennis ball, or other tool to massage your muscles. Your muscles (especially neck and jaw) will tend to clench in the cold so rolling and stretching each day will be helpful.
Shovels, salt of some sort for your walks. Always buy that stuff before you need it because when the snow arrives it will all be sold out.
Hothands Mylar lined blankets Emergency lights.Consider picking up some RV antifreeze to pour in your toilet tank if it's bitterly cold and don't forget to let your taps drip.
If you can't get the big stuff, work your way backwards and focus on building up the "small stuff."
If you can obtain propane cylinders (in USA they look like this: https://www.walmart.com/ip/Coleman-Propane-Camping-Gas-Cylinder-2-Pack/20971271 for the small ones, but with the right adapter hose you can use the 20-lb tanks), then
If you expect the blackouts to be temporary and short-term, then even without any kind of solar panel you may as well have one or more solar banks. You charge them while the power's on, use them during the blackout, and when the power is back charge them again.
If that does turn out to be the case, then you'll mainly want to focus on creature comforts for the hours or days the power is out. This also means you won't use as much power while the power is on, though.
And if it turns out to be more than hours or days at a time, well, you'll still be happy you have those hot hands...
We're going there this weekend also, and I always bring hand warmers and toe warmers. Not ideal due to the single use aspect, but I can't sleep when I'm freezing. I stick the self-adhesive toe warmers strategically on my body (lower back, feet) where I need them. REI & Amazon always have them.
Some single use hand warmers in your pocket are a lot cheaper then replacing a $200 tent.
https://www.amazon.com/HotHands-Hand-Warmers-Odorless-Activated/dp/B0007ZF4OA
Link for reference: https://www.amazon.com/dp/B0007ZF4OA/
Bought a box for testing. They really do last 10 hours, and they get HOT. My partner sleeps super cold, so we picked up some plain cotton drawstring bags from Amazon as well, and stuff the warmer inside one of those, then stuff it in the footbox. They get too hot to keep directly against your skin.
Like these you put in your gloves or boots when it is very cold - https://www.amazon.ca/HotHands-Hand-Warmers-40-pairs/dp/B0007ZF4OA
Put one of these hand/foot warmer jawns into your socks.
https://www.amazon.com/dp/B0007ZF4OA/ref=cm_sw_r_apan_glt_i_AC71YHNM3Y5W9FD9ND5G
On a more serious note, this isn't normal you should go see a doctor.
You will probably be fine. You already said you want to remove any heavy items in the enclosure. The biggest issue you will have (I assume because of the units and distance you are talking about you are in the US) is keeping the temperature decent. Use a small cooler with a heating pack (e.g. Hot Hands) to keep it warm. I suggest that anyone traveling in Northern climbs keep a pack of these around anyway for safety.
Something like these Hand Warmers & Toe Warmers
Hold one of these hand warmer packets to the finder with a rubber band, and cover that with the T-shirt to insulate it. Will last you hours rather than minutes.
How about sticking these in your socks too!
Not necessarily this brand, but I used to use these.
They're reusable and I kept them in my glovebox.

These things are amazing: https://www.amazon.com/HotHands-Hand-Warmers-Odorless-Activated/dp/B0007ZF4OA
and i think they also make a rechargeable version, but I've never tried it
There are e-bike mechanics at bike shops. It's a market that is getting huge. https://electrek.co/2021/10/05/electric-bicycle-sales-are-growing16x-higher-than-general-cycling-heres-why/
These bikes motors last for thousands of miles and when you do have to replace a bike, they're cheap compared to a car. I'm not spending money monthly on gas, insurance, car payment, parking, tolls, pricy repairs (much less than a car). Charging the battery is on par with charging a few laptop batteries
In winter months, people can still ride. It's like skiing/snowboarding, or snowmobiling, you dress for it and bring hand warmers
You made me chuckle! Not those hot pockets. https://www.amazon.ca/dp/B0007ZF4OA/

Hand warmers. https://www.amazon.com/dp/B0007ZF4OA
I put two or three 10 hour hand warmers in my sleeping bag every night and it stays extra toasty.
a hand warmer over the sensor might work in a pinch...
Heat always helps me - you could order some hand warmers and keep them in your hands on your way to class and in class.
At home I always have a rice sock around that i use for stiffness and aches and pains.
I'd also strongly suggest Voltaren if you are in the US or a country that sells it over the counter. It's a topical NSAID and it has worked really well for me on my hands.
You might also want to see if your school as a PsA support group and get tips from other students, and a little community support at the same time.
Are you in a cold climate?
I can’t comment on the condo part but I got my mailman a box of these hand warmers to help warm up during winter deliveries.
You'll need some source of heat 100%. Short term you can buy a big pack of hot hands hand warmers and use 1 or two in your sleeping bag every night.
For about the same price as a cheap sleeping bag you can get a box of 40 pairs of disposable hand warmers too:
https://www.amazon.com/HotHands-Hand-Warmers-Odorless-Activated/dp/B0007ZF4OA
Which can help make up the gap if needed.
I was going to give these a try- https://www.amazon.com/HotHands-Hand-Warmers-Odorless-Activated/dp/B0007ZF4OA
Here’s an article I wrote for my online community paper:
​
HOW TO: help the homeless
[LEFT COLUMN]
[BLESSING BAG GRAPHIC] I saw this idea on Facebook and thought I’d pass the thought along. Somebody came up with the idea of making “Blessing Bags” for the purpose of giving them to people who are homeless/down on their luck. Each Blessing Bag consists of a gallon-size recloseable/zip plastic bag filled with practical items.
Here’s a list of things you can slip into the bag. These are just suggestions—you might come up with better ideas. If you do, please let me know! (By the way, making Blessing Bags could be a nice group project, and buying supplies in bulk is a good way to defray the cost of putting them together.)
​
[RIGHT COLUMN]
​
Click here for some care package ideas from Dollar Tree.
When you have your Blessing Bags all arranged, consider adding a hand-written note with a positive statement like “Packed with love by the Smith family.”
Your next step is trying to figure out how to get your Blessing Bags to people in need. One idea is to keep them in the car in case you come across someone who looks like they could use a Blessing Bag—or maybe you want to drop them off at your house of worship. If your church/masjid/temple distributes food or clothes anyway, they probably won’t mind handing out Blessing Bags as well. Unlike the big cities, Durham’s homeless people are not easy to spot. Every now and then you might notice a tent encampment in the bushes or not too far from the expressway. If you don’t think it’s safe to call out to see if anyone’s around, it’s probably okay to leave a couple of Blessing Bags in the area (even though it might not be as satisfying to wish someone well face to face). If that doesn’t work for you, then feel free to drop them off at a shelter.

[hand warmer] (https://smile.amazon.com/HotHands-Hand-Warmers-Odorless-Activated/dp/B0007ZF4OA?sa-no-redirect=1)

[antenna, no coat hangar required] (https://www.byonics.com/antennas)
Any antenna thats made to operate on 144.390 mhz (assuming you are in the US, other countries you'll have to check your band plan) will work. I make mine from 2 19" pieces of 20 gauge wire.
I can't speak to the dew conditions or climate down in Florida, but I can say that dew control is really, really convenient.
I ended up making a passive hand warmer dew heater for my finder scope because I got so sick of using the hair dryer on it every hour or so.
I went to walmart and bought $5 worth of fabric, elastic, and velcro, then Home Depot to get $3.20 worth of braided copper wire, and created a pocket wrap that accepts 1 or more of those chemical hand warmers. The copper wire helps distribute the heat around the finder objective, with the hand warmer being placed at the bottom so that the heat naturally rises over the objective anyway.
In the last image you see some reflective bubble insulation which I later sowed into a fleece liner with some fiberglass stud batting insulation I had lying around. This sits over the hand warmer pocket and traps the heat, meaning a single pocket hand warmer lasts all night long, even in horrible dew conditions.
You can buy a huge supply of those hand warmers from Amazon and it comes out to something like $0.30 / warmer. An active dew prevention system with a proper dew heater would be better in the long run, but this was stupid cheap and easy to make, and works perfectly.
The only issue now is my secondary mirror likes to fog up a lot, so I'll probably have to craft a similar dew shield for the UTA. But a dew shield only works so well. Right now I'm learning how to build my own electric dew heater for a fraction of the cost of buying one.
I have the same problem. I started using hand warmers, slipping them into my boots and pockets, and it's been great.
Something like this: https://www.amazon.com/HotHands-Hand-Warmers-40-pairs/dp/B0007ZF4OA
http://www.amazon.ca/HotHands-Hand-Warmers-40-pairs/dp/B0007ZF4OA
They are single-use chemical heating pads. You activate them by shaking them and they get very nice and warm. Handy to keep around.
Last winter was ridiculously cold so I tried to find the best gloves this year. I came to the conclusion that you need at least 2 pairs (maybe three) for the varying conditions.
For the super cold days I settled on Black Diamond Soloist finger gloves. I also bought a case Hot Hands for when the conditions change on the trail.
I would also throw in some hand warmers in cold climates.
I'm in Austin so it's not as cold but the few cold nights we get can really Suck since you don't have any exposure to come weather.
That's why when I know it's going to be cold at night. I bring a few extra hand warmers to pass around the bus stops that I know homeless people frequent.
For $20 you can get a nice box of 40.
HotHands Hand Warmers (40 pairs) https://www.amazon.com/dp/B0007ZF4OA/ref=cm_sw_r_cp_apa_L.4myb4QDPH1A
You can get them on Amazon, you can probably get some for cheaper, these are the just the first ones I saw. Sometimes they might have them at your local sports store (usually in the winter)
