The Science Behind Temperature for Sleep
Our sleep is managed by our sleep-wake cycle and our daily routine. Our core body temperature is around 98 degrees, but this might fluctuate during the night, i.e., when we sleep. The temperature falls to a certain point throughout the night depending on the body type, and it rises in the morning. You might have noticed that your hands and legs feel warm. Well, that is because of the core temperature shifting during the nighttime.The process that happens every night where the temperature drops is called vasodilation; due to this, the circadian clock sends signals to the brain to increase blood production, which expands the blood vessels. The increased blood production is the actual reason you feel warm when you wake up from sleep. If you are sleeping in the cold, it can affect your sleep by making you feel cold in the middle of the night. A 2012 study found that room temperature plays a vital role in providing quality sleep.What Is the Best Temperature for Babies to Sleep?

It could also make it harder for you to fall asleep or could even give you an unexpected cold. Ensure your head and feet are always covered while sleeping in a cold environment, as cold feet and ears can easily make you fall sick.What Happens if Your Bedroom’s Temperature Is Too Hot?
