Temperature plays a major role in sleep quality. See how each part of your body reacts to temperature changes — and what you can do to get better quality sleep.
Fact: 83% of couples sleep too hot or too cold.*
Head: Your brain sends signals to your body to sweat when you get too hot, or to shiver when you are cold.
Tip: A warm shower before bed kicks off the body's cooling process, which helps you fall asleep faster.
Chest: A hot, burning feeling in the chest could be the result of heartburn, when food or acid leaks from the stomach to the esophagus.
Tip: Try to eat dinner at least two hours before bedtime and avoid excess sugar. Also, take advantage of mattresses that can raise your head, like the Sleep Number 360® smart bed, to keep your head and chest higher than your abdomen.
Hands: Your skin's blood vessels expand to cool the body, so your hands may feel warmer at night.
Tip: If you're hot, don't cover your hands. Use temperature control bedding and beds which help absorb excess heat and release it as you cool down.
Abdomen: In the late afternoon, your metabolism slows down, and the core temperature in your body starts to lower as it prepares for sleep.
Tip: Begin a pre-bedtime routine 20 minutes to 1 hour before bed to help your body wind down.
Feet: Cold feet? It may due to poor circulation or nerve damage, but it could simply be inherited from your family.
Tip: Put on some wool socks. Even better: Take advantage of Sleep Number's FlexFit™ Base with a foot warming option designed to help you fall asleep faster.
Research shows that Sleep Number® bed owners get almost an hour's more sleep per night than the average sleeper.**
