Whether it is a normal rest or a lunch break, I often feel sleepy suddenly. I hope Mr. Feng Shui or other psychological AIDS will pass by.

I used to be like this. This is due to excessive mental stress. I must often suffer from insomnia or dreaminess when I sleep at night, and I often have a bad rest. You must learn to adjust yourself to relieve stress. Don't stay up late at night,/kloc-go to bed around 0/0. If you can't sleep, listen to music and force yourself not to think about things that make you anxious or afraid, or things that make you excited. If listening to music doesn't work, do you like reading novels? I suggest you use p3 to download your interesting storytelling novels online and listen to them before going to bed at night. When your attention is completely absorbed by the novel, you will fall asleep after a while.
