Fever is a surge of heat to any part of our body.
We feel heat when the subcutaneous vessels dilate, dramatically increasing blood flow to the surface of the skin.
Why does it get very hot at night
Night sweats can be a symptom of various diseases: thyroid dysfunction, diabetes, endocarditis, neurological, autoimmune and other diseases.
Sweating can also occur due to insomnia, stress or depression.
How does heat affect sleep
When the bedroom temperature increased by one degree, sleep efficiency dropped by 0.06%.
In addition, at higher temperatures, subjects took longer to fall asleep and overall sleep time was shorter.
When it's hot, you're more likely to wake up at night. High temperatures also shorten the phases of deep and REM sleep.
A review article published Thursday in the Journal of Sleep Research traces some of the problems associated with trying to sleep during the heat.
What to do if it's hot and you can't sleep
In the heat, it is often difficult for us to fall asleep: the pillow is not positioned correctly, it is hot under the blanket, it is difficult to breathe and, as a result, the process of falling into sleep is disrupted.
But experts from the British Sleep Foundation say a nice hot shower or bath before bed can help.
We previously talked about how magnesium affects sleep.
