I already knew this. This is why I have trouble sleeping in the summer.

That’s what I told my spouse but he said I’m weird and crazy . He said ideal room temperature is 77F regardless. I used to wake up every hour because I felt hot and my heart rate was also racing. Now that I’m sleeping alone, I can sleep better when I turn the heat down in the middle of the night :)

Recommended temperature for deep sleep: 65°
My south facing room in summer: 80°-90°, it stays that way until midnight, then drops to 75°-80° by sunrise.
One of the many reasons summer is the worst time of the year.

Having the heat between 62 and 65 degrees is great for me in the winter time. It’s easier to sleep and it saves money. But unfortunately you can’t do that in the summer unless you want to have an expensive bill. That’s the only downside to that. And that’s why I get hot and sweaty in my sleep in the warmer months.

I sleep much better in cold room but I grew up in Wisconsin in a drafty house we just piled on the blankets and waking up was a shock get out of a warm bed to ice cold floor better then a cup of coffee

Who can afford to blast their A/C down to 65 degrees! My electric bill would be outrageous!!!

[.Tapestry]

my body doesn't know what temperature it wants to be. i drift off feeling cool and needing covers, but then i wake up very hot (usually accompanied with a nightmare)

[stewdog]

I agree that it’s better to sleep with cooler temperatures. Sleeping with minimal breathable clothing, using breathable lightweight blankets and keeping your distance in bed from your partner (when you are initially falling asleep) are all great ways to fall asleep faster!

[hardgamer]

Reallyb 65 are you kidding I sleep at 73 and its enough it saves on my bill

[multuminparvo]

My landlady keeps the temperature between 72 and 74 every night to save money on electricity, and I've tried everything to keep cool. I'm ready to move!!!

[higurashianduminekoconnect]

Sleep at 65° get sleep. also sleep at 65° be broke and out of my house because electric bill got too high. Another solution I cannot put into practice how about an actual solution for me for some of us who can't afford to be stupid with electric bill.

The most tired looking girl is conducting sleep studies 😳

[cristopheralexander]

I sleep with the AC on even tho it's like 0 degrees outside.

[tardwrangler]

So I guess that a temp of more than 67 f/19 c is better for staying awake

The average temperature in apartments in winter: Italy - 17 degrees, Germany - 17 degrees, France - 17 degrees, the Netherlands - 16 degrees, Great Britain - 15 degrees, Japan - 10 degrees.

The Russians are shocked by these figures. According to Russian sanitary standards, the temperature in the apartment should be at least 18-20 degrees Celsius. According to Russian legislation, for each hour of deviation in air temperature in a residential building (in total for the billing period), the monthly fee is reduced by 0.15% of the fee determined based on the readings of metering devices for each degree of temperature deviation. Thus, at a temperature of + 17 ° C, payment per month should be reduced by about 87%, and at + 16 ° C, payment is not required at all. If in Russia they used to heat the same way as in Holland, Great Britain and Japan, then the Russians would not have to pay for heating.

In the above countries, the temperature does not meet sanitary standards!

The colder the bedroom, the better. And that is good for marriages too.

[pradearable]

65(18 degrees C) is too cold, 22-23 C is perfect..

[teresaolofson]

when i am super cold i cannot fall asleep however i will end up waking up if i am too hot so i have to go to bed warm and cover up and then i sleep with the window open

[cbcedbg]

24 C is better for room cooling & set 27 c for saving electricity bill

[StabbdByAJAX]

And my parents are too stubborn so in summer they keep it 89 f smh
