Cold feet while trying to sleep

Now that we here in the Northern Hemisphere are experiencing colder and colder temperatures each day, a familiar annoyance for some bothering going to sleep at night...COLD FEET !!! 🥶

So something to talk and share ideas about with others here. For those many that keep their homes warm, less likely ever an issue. Also we thin folks and women tend to be more affected. But for those like this single frugal senior that tends to limit heating in my residence where 2 decades ago I turned off gas heating, dress warmly, and just occasionally turn on a small ceramic element space heater, cold feet is a nightly issue.

This last chilly week the space heater has kept my downstairs living room out of high 50Fs instead to low 60Fs temperatures. At such temperature, it doesn't really matter what socks or even down booties I may be wearing if I've been say sitting at my computer for a few hours. Living not far from the coast, our nightly temperatures average 47F in November and March, 45 in Feb, and 42F in Dec and Jan. My monthly winter electric bill for an old 60s era 2 bdrm 1200 sq ft 2 story 4 plex unit with old thin wall insulation and windows is only around $45/mo. During day hours, my old inefficient refrigerator, LED lighting, tv, and 2 computers also help raise indoor temps.

Of course, keeping the rest of one's body warm before sleep time will also affect feet. As will wearing warm socks, slippers, or booties. As a decades old backpacking enthusiast into high alpine wilderness areas often over 10,000 feet in elevation where frosty temps are common all summer months of a year, the problem is a more difficult issue to deal with than at home. At home one common known strategy is to take a warm shower before getting in to bed. What I more often do at home I'll share herein is turn on a hair dryer blowing warm air onto my cold feet for a couple minutes that also helps dry out outer skin layers with moisture. Out in wilderness inside a 15F goose down sleeping bag within a tent, there isn't any solution. Pushing the bottom of one foot up against a warmer calf or already warmed sleeping bag sections I may have been lying on have little a effect beyond making those areas chill. ☹️ As a light sleeper, it can keep me awake for an hour or two while all else is comfortable. When inactive, feet cool, blood vessels constrict reducing circulation. Another nugget of wisdom is putting one's cool feet into say an otherwise warm shoe, bootie, or sleeping bag doesn't work then for the same reason, a good way to keep a cold drink cool inside a car baking in the sun while one is off wherever doing something is to place it inside insulation like a sleeping bag as insulation works both ways.

Sometimes my feet are intensely hot and I have to go stick them under cold water.
Other times, on cold nights, they can get cold. I always take a hot shower before bed.
I leave the heat off all night to save money.
If it's only my feet, as I use heavy wool blankets in winter, one thin I do is:
Heat a towel in the dryer and wrap it around my feet before sleep.
By the time it cools, you are asleep!
 

As someone that occasionally used to tent overnight outdoor snow camping, I own some warm well insulated duck down booties. As already noted personally, warm socks or my booties, don't help warm up my own feet if already cold because my body constricts extremity arteries reducing blood flow. Also if feet have been inside warm socks and shoes for hours, although not sweaty, the top layers of human skin will likely contain a fair amount of absorbed water that then evaporates further cooling one's feet.

Interesting mentioned side issue is how some of us find feet in socks in bed uncomfortable. If my feet are fine, not cold, I can wear socks or leave them under warm bedding after starting to try and sleep. However after waking up as I tend to do a few times each night, invariably I need to put my bare feet out in a cooler place than the rest of my body. Usually during winter ski season in warm motels and lodging beds will pull up the foot end of the tucked in bedding so later I can later allow feet to just be under sheets, not blankets.
 
I like loose white cotton socks, fairly thick ones. I cut off the tight band at the top.

I also have lots of blankies, especially on my legs and feet. Sometimes I get rid of the covers, but the socks stay on!

A friend used to make hot water bottles for herself. She'd fill a glass juice bottle (with a tight lid) with hot water, then cover that with a heavy sock. She'd take it to bed and snuggle her feet up to it. Then if her feet got too warm, she'd move them away from the bottle.
 
What I do to solve the problem of cold feet & the rest of me:
In winter, I sleep on a polyester blanket & put another polyester blanket over me. Sheets are always cold.
I also sleep in sweat pants & a long-sleeve polyester shirt. At night, the house is around 66 degrees & I'm warm while I'm sleeping.
 
Two main helpers for ice cold feet. I’m an expert on this!!!

A microwaveable heating pad. I buy mine from a farmer. You can make these bags yourself if you can sew; I can’t. Stuff it with a grain; do some research for the better ones. The ones I buy are ~10-12 inches long. Don’t overheat. Maybe 2 minutes on high. Once you’ve made one, you can make more.

An old-fashioned water bottle. I wrap it well so I won’t burn myself. I buy heavy duty and disobey the rules; I use boiling water. It’ll hold that heat for hours. The key thing to watch is if the plug area is looking worn out.

The third choice is an electric heating pad. It’s kind of awkward flipping it around and not allowing yourself to scrunch it up.
 
I must be missing the point, @David777 — if your bill is only $45, why wouldn't you just turn up the heat to a comfortable level. Or do I just not get it?
As noted, turned off my central gas heating years ago. To get that back on will require contacting electric utility PG&E who will send out a service person as well as involve billing changes. So have tended to avoid doing it. In any case a situation have at times reconsidered when unusual cold continental winter air masses keep night time temps in 20Fs for days.
 
I wear fuzzy socks to bed - they are loose and not too restrictive.
I learned from the HVAC people to keep all the doors open upstairs so both floors are evenly warmed. In the past, I would shut my bedroom door and in the morning, the downstairs would be colder. Not anymore.
When I lived in an apartment, I used an electric heater to heat the room until the heat was turned on in the apartment.
 
Although I related out in wilderness I have no solution to warming my feet if they become cold before getting into my sleeping bag. I actually didn't remember a couple things. Hand warming chemical packs like HotHands are used by many winter sports enthusiasts and besides into gloves can also be put into socks and boots. Just went onto my long gear list so won't forget next time. Some winter snow campers will boil water filling water bottles however that requires using possibly limited fuel to heat water.
 
@David777 mentioned boiling water to fill hot water bottles while camping. For this purpose, it's not necessary to boil the water. Heating the water to boiling wastes fuel, because it takes energy to transform water from a liquid to a vapor. You're better off heating the water to below the boiling point. It will still be plenty hot.

The following might explain it better than I can.

I sleep with a pillow on top of the blankets over my feet. It works pretty well for keeping my feet warm and cozy. I'm a side sleeper, which is why the pillow doesn't fall off. It probably wouldn't work well for a back sleeper.
