Why Is Your Bed Making You Sweat?

Why Is Your Bed Making You Sweat?

Waking up hot and sweaty can be frustrating. If you’re constantly waking up to take off covers, turn down on the fan or roll over to get cool, it could be any combination of issues. So why do you sweat in your sleep? Consider these factors if your sweet night turns into a sweat night

Take a look at your mattress

Soft beds are comfortable to sleep on. You sink in and feel safe, but you also lose a lot of exposure to air. When you decrease the surface area your skin uses to cool you off, you will heat up faster, causing sweat. Inversely, firm beds expose more area to the air, keeping you cool for longer. Memory Foam mattresses are notorious for causing sweat, especially as they age. New technology — like's bed — is looking to solve this problem with its advanced memory foam bed made with triple layer design and a layer of cooling gel so you can sleep comfortable and cool. Also, mattress types statistically cause more or less heat and sweating. Latex mattresses breathe well and water beds absorb a lot of body heat. Memory foam and innerspring mattress owners complain the most about getting too hot.

How do you cover up?

Sheets made from synthetic materials like polyester don’t breathe as well as cotton or bamboo. Cotton and bamboo sheets can help breathe but also remove moisture that makes you sweat. Also, if your covers are thick, they won’t let out as much air and moisture as well as reducing surface area for your skin to cool itself.

Bedtime rituals

Many factors attribute to sweating while asleep, regardless of beds and bedding. Sleeping nude makes you more likely to sweat, likely because nude sleepers tend to cover up more. Wearing a thin shirt can help you feel less exposed and able to throw off a blanket. If you like to exercise before bed, this can take your body temperature out of homeostasis. It takes hours for body temperature to become steady after working out. The best solution to this is to work out in the mornings or right after work. Another way to cause fluctuations in your body temperature is eating too late or eating spicy foods. Digestion takes a lot of energy, making your body work overtime on that late meal or spicy food. The majority of body heat comes from organs so let your stomach rest at bedtime and you’ll stay cooler.

Pay attention to your body

WebMD lists many more physiological reasons for sweating. Fluctuating hormones can cause your body to sweat too — especially in women undergoing perimenopause or menopause. Sickness, such as tuberculosis or bacterial infections or cancers like lymphoma cause sweating too. Also note, certain medications can lead to sweating too, such as aspirin, acetaminophen or antidepressants. Low blood sugar causes sweating too, making diabetics more at risk for hot sleeping. So why is your bed making you sweat? With so many factors, it could be any combination of the above. Make these changes and you can be sleeping cool all night.
