Is it better to sleep in cold or warm?

Over the years, I have realized that sleeping in a slightly cool room with a light cotton sheet gives the most undisturbed rest. A hot room will only make you toss and turn all night. Just don't make it freezing cold either.

I used to ignore my extreme sensitivity to cold rooms and kept shivering to sleep, which turned out to be a thyroid issue. If you find yourself unable to tolerate normal temperatures, please go for a proper checkup instead of just adjusting the AC.

Scientific consensus suggests that a cooler room temperature, around 18 to 22 degrees, supports the body's natural circadian rhythm for better sleep. However, if you have conditions like asthma, very cold air can trigger symptoms, so consult your doctor to find what's safe for you.

I recently changed my bedroom setting to a cooler temperature because I was having terrible night sweats and bad sleep. It literally fixed my morning tiredness within a week, so a cooler room definitely works better.
