When the weather is hot, I often get up at noon with a headache and a cold forehead. Excuse me, what is this?

If you sleep for a long time at noon and wake up passively for more than 1 hour, you may have headache symptoms. Because the brain will go into a deep sleep state after lunch break for more than an hour, passively waking up at this time will produce headache symptoms. Compared with shallow sleep headache with sleep time of 1 hour, there are few cases.

Generally speaking, it is better to take a lunch break of 30-45 minutes, which can relieve fatigue to some extent. On the other hand, symptoms such as headache can also be avoided.
