1. What is the Science Behind the Ideal Sleep Temperature?

There are science-backed reasons why a specific temperature between 60 to 67 degrees Fahrenheit is adequate to ensure a better night's sleep for any individual.

According to sleep specialists and scientists, the body's internal temperature shifts during the 24 hours. These are due to the body's biological processes known as the body's circadian rhythm. When an individual goes to bed, the body begins to shed heat. This means that an individual's core body temperature cools overnight and reaches its low point near daybreak.

Hence, if the temperature in your sleep environment is too hot or too cold, it causes your body to experience a significant temperature change, which ultimately causes poor sleep. A study conducted in 2012 showed that bedroom temperature plays an essential factor in achieving quality sleep. Want to know why it happens and how this temperature might impact your sleep? We have it covered for you below.

2. How Does Temperature Impact Sleep?

When you haven't gotten a good night's sleep, you feel fatigued the entire day and cannot wait to go to bed and shut your eyes again. However, if the temperature in your room is not correct, this might also be the same for you the next day.

While it plays an essential role in melatonin production, temperature unarguably plays a vital role in maintaining your sleep. How so? Well, having an optimal temperature in your room significantly impacts your sleep onset or sleep efficiency. This is because too much hot sleep or exposure to heat can increase wakefulness and decrease rapid eye movement or REM sleep. On the other hand, if the room temperature is too low, you will also feel uncomfortable and thus have difficulty in sleeping.

Hence, according to several sleep specialists, thermoregulation is vital in staying in restorative slow-wave sleep stages. These are the stages where your body gets the best rest. Do you want to know how sleeping too hot or cold can impact these stages? Hop on below.

2.1 Sleeping Too Hot

If the room temperature is too hot or humid, an individual might experience restlessness or fail to fall asleep. In addition, some people constantly feel hot when in bed and struggle to cool down at night, which can be very frustrating and lead to destructive and uncomfortable night sleep. People of any age will experience the feeling of being too hot to sleep. However, the survey data shows that more than 62% of people aged 16 to 24 described themselves as hot sleepers.

2.2 Sleeping Too Cold

While sleeping hot impacts your sleep, sleeping too cold also has downsides. While cold exposure doesn't impact your sleep cycle like it does for hot sleepers, it can still lead to other health issues. This is because when your body is cold, the body takes it upon itself to make it warm again.

The blood vessels constrict to enable this, and the breathing becomes shallow. All this puts extra pressure on an individual's cardiovascular system and changes blood pressure for better temperature regulation.

3. Does the Body's Sleep Temperature Change with Age?

While we did mention that the adequate temperature for normal adults to sleep is 60-67 degrees, do you think this will be the same for older adults, too? Well, no! According to aging research and peer-reviewed studies, our body goes through several changes as we grow old. One such change happens to be a decrease in body temperature, and another is a decrease in melatonin production.

Due to this, with age, the body of older adults weakens, and it takes time to adjust to newer impacts and changes around it. The best sleeping temperature for older people is 70-74 degrees Fahrenheit. The same is the case for babies, who sleep best at temperatures between 68-72 degrees Fahrenheit.

5.2 Feeling too Hot?

  • Take a Warm Bath an Hour Before Bed

According to several doctors and sleep specialists, taking a lukewarm bath before bed can help decrease the core body temperature while promoting melatonin production and sleep onset insomnia. This also ensures good sleep hygiene and helps you fall asleep.

If you don't like night showers but are tired of your sleep problems, soaking your feet in lukewarm water for 20-30 minutes might also work. This is probably one of the easiest yet most effective tactics to attain better sleep.
