Absolutely. I can’t fall asleep unless it’s 60-65.

Do you check the temperatures a couple of hours before bed and then adjust the cooling accordingly? I struggle to change my indoor temp based on the daily temp outside, I usually just keep it at 64 degrees.

Try living with hot flashes every thirty minutes. I could not sleep for years but, after fifty years, they are finally on the wan.

That's a little on the low end for me, but I think it depends a bit on your climatizatoon and conditioning.

Yup. I fall asleep best in cool temps around 10 pm. Then I wake up around 2 am and need to get warm to fall back to sleep.

Too warm, and I have no chance at all of getting any sleep.

I have yet to find myself too cold to fall asleep, so long as I have a comforter.

I’m in Northern California and we don’t have AC. 68-70F feels best for sleep with spring/summer/fall silk duvet insert. When I use light weight down comforter, I get sweaty at times. I feel like for down comforter room temperature needs to be lower that 68F or one need to be a cold sleeper.

The optimal temp identified was 68 degrees Fahrenheit

64-68 is definitely an ideal range for me

For me personally if it’s too warm it does make sleeping much more difficult

I wanna say there some research out there that says sleeping in a cooler room improves sleep quality. I’m guessing ‘cooler’ is probably subjective

Around 65–68°F (18–20°C) cool, but comfortable for deep sleep.

19-20 degrees Celcius

74

I like it to be around 65 degrees Fahrenheit for sleeping.

65 F.

For me like 55° F (~13° C). Its nice when the room is a bit chilly and you can rely on body warmth under the covers. My room at school would get a bit chilly like that cause the insulation was utter shit

75 to 78 F (24 - 26 C). I live in a hot place, so I’m acclaimed to warm temperatures. I can and have tolerated an indoor temperature of 72 F, but I can’t stand any lower than that.

I am constantly being told I am nuts because I like to sleep at 18 degrees Celsius/64F. Or even colder if I can. But especially while travelling this seems impossible. I walked into a hotel room today and it was set at 24 degrees. How can anyone sleep like that? Up past midnight waiting for the room to cool down a little. But the thermostat doesn’t go down past 20. Feel like I’ll be sweating all night. Just wondering if I am the only one.

18ºC/64ºF.

63°F is perfect

No, most people set it to 70; demanding anything higher than 80 makes someone an asshole.

I love it cold. Winter here gets in the 20's and 30's F often and sometimes in the teens. I keep my thermostats on 52˚F mainly because that's as low as they go. But I think that's a good temp for me, I sleep in long thermal pajamas and sox. Also under several blankets and I LOVE it that way!

66ish. The minute you get warm under the blankets, you’re out!

Somewhere between cold and warm.

68 f

69F. Sexual.

68°F

During the day I don’t really mind what it is but at night especially in winter I prefer sleeping in a cold room like 68-69ish degrees. The colder it is, the better I sleep.

25°C

68 F

65 degrees, i always say that if its 65 outside I'd throw a mattress into my yard and sleep. Somehow its cozy af

Very cold. I wanna be a snug lil cocoon of blankets.

Mid 60s or anything colder <3

67 Fahrenheit. Any higher and I’m waking up drenched in all the wrong areas
