Slightly warming your skin can help you fall asleep faster, achieve deeper sleep, and rest longer throughout the night.
Body temperature and the warmth of your sleep environment have long been known to influence sleep quality. Researchers at the Free University are now investigating skin temperature specifically.
Why it works:
The hypothalamus in your brain regulates both sleep and body temperature. Warm skin sends signals that promote sleep onset, while cooler skin promotes alertness.
Putting it into practice:
Studies used specialized pajamas to control skin temperature. Though not ideal for nightly wear, innovations like advanced mattresses or duvets that manage skin heat could soon make this accessible.
