Why can't you sleep in summer?

Most of the reason is that your own biological clock has changed. If you stay up late frequently for several days, your original biological clock will be disrupted. Another reason is that the temperature is higher in summer, the body's endocrine is more vigorous, and the spirit will be boosted.

I want to remind you that summer is actually very easy to get tired. Many times you don't realize it yourself. Good sleep and regular work and rest are the key to health, otherwise your body will be damaged unconsciously ~ ~ Take care of yourself! !
