The nighttime temperature has dropped significantly compared to when we suffered from tropical nights. If you feel like you slept deeply and woke up refreshed, it's not just your imagination. Sleep is closely related to body temperature.

 

A lower body temperature helps you sleep better.

 

To sleep soundly, your body temperature needs to drop slightly. The internal body temperature, known as 'core body temperature,' usually ranges between 36 and 37.5 degrees Celsius.

 

The core body temperature of a person lying down to sleep drops by 0.11 degrees compared to when awake, and after falling asleep, it decreases by 0.15 to 0.31 degrees. When the core body temperature drops, the sleep hormone melatonin is secreted, increasing the desire for sleep.

 

The time it takes to fall asleep decreases, and it becomes easier to sleep deeply. Conversely, when core body temperature rises, the desire to sleep decreases. If the ambient temperature does not drop below 25°C during the night, body temperature also does not decrease well, making it difficult to sleep soundly.

◇ If it still feels hot, lower the humidity and turn off the PC in advance

 

It is true that the weather has become cooler, but for some people, last night may still have been hot.

 

In such cases, drinking a glass of cool water before bed can be helpful.

 

It can help lower body temperature quickly to aid in falling asleep.

Using a dehumidifier to lower indoor humidity is also good.

 

The most ideal humidity for sleep is 50%.

 

If the humidity is high, the room can feel hotter even at the same temperature. High-performance computers and large televisions emit enough heat to raise indoor temperatures, so it is best not to use them 1 to 2 hours before sleeping.

 

Meanwhile, if you have been lying down for more than 20 minutes and still can't fall asleep, don't just keep lying there; come out to the living room and read or do some stretching. When you feel sleepy again, lie down.

 

===============

I didn't think about the humidity.

I should check again in the evening.

The best humidity for sleep is 50%.

I should remember.
