How Does Heat Affect Sleep? 

Heating your bed isn’t always the best way to heat Sleep, even though it’s comforting. You don’t want your body to have to work too hard in your bedroom, so find out how cool it should be.

Summer may seem counterintuitive, but the lazy days make sleeping a challenge.

With our dream team and sleep data and science partners, SleepScore Labs, we have delved into the latest sleep science to find the ideal temperature for supporting sleep in summer’s excess heat.

During these hot, humid summer nights, we’ll share tips for sleeping cool and comfortably.

What happens to our body temperature when we heat Sleep?

The temperature of your body fluctuates throughout the day, just like the outdoors. Your body will adjust to these changes as your circadian rhythms (its internal clock) will align.

Melatonin is released by the sun as it sets. This causes feelings of tiredness and a decrease in core temperature so that the body can go to sleep faster. You can think of it as your body’s thermostat lowering to a set one or two degrees lower than when it’s awake.

Despite this not sounding like much, if your temperature increases by just 2 degrees, it could be considered low-grade fever!

Hot Body Cooling Techniques

Skin and breath release heat, lowering body temperature. During warm weather, blood vessels at skin level increase in diameter (or vasodilate) to absorb more heat.

Evaporative heat loss, also known as sweating, is the second mechanism. According to Roy Raymann, Ph.D, principal sleep scientist and innovator at SleepScore Labs, when the body struggles to remove heat this way, it can open up extra vessels near the skin or sweat even more to increase heat loss.

Shunting vessels can be more quickly heated by opening them. When you get warm, you’ll probably notice that your fingertips, ears, and hands start turning red first.

According to Raymann, sweating increases the body’s ability to lose heat at night due to hot days.

What Is the Effect of Hot Weather on Sleep?

When temperatures are extremely high at night, as they are during balmy summers, we tend to have difficult Affect Sleep. A study discovered that sleeping in an environment between 87-100 degrees Fahrenheit can disrupt sleep and reduce important stages of sleep, such as slow-wave sleep and rapid-eye-movement sleep (REM).

Sleep Quality when it is Extremely Hot or Humid

Sleep is significantly impacted when temperatures are excessive overnight. In places with year-round high temperatures, hot climates can mean different things, so we wanted to find out how sleep quality varies during the hottest months.

It may not be applicable to places with higher levels of humidity. According to researchers, humid environments make it difficult for us to expel heat because they increase thermal load and inhibit evaporation.

Secondary environmental factors, such as natural disasters, can also disrupt sleep during hot weather.
