Studies suggest that the ideal temperature for sleeping is between 15.5 and 20 degrees Celsius.
Temperatures above 24 degrees and below 12 degrees Celsius can be disruptive to sleep.
Temperature that fall within the ideal range aid the decrease of a person's core body temperature that causes sleepiness.
Body temperature has also been linked to the amount of deep sleep you get at night as well.
People sleeping in warmer environments suffer more from wakefulness throughout the night, while those who have cooler temperatures enjoy more deep sleep.
