Therefore, it causes a temporary lack of blood supply to the brain and makes you sleepy.
Don't eat too much at every meal, just drink some tea.
After eating, people's stomach peristalsis takes up a lot of blood, resulting in insufficient blood supply to the brain, so you are groggy.
There is a proverb called "sleepy in spring, sleepy in autumn, and sleepy in summer". The high temperature in summer really makes people feel depressed all the time, especially at noon. Being able to take a nap at this time can refresh people and continue their work in the afternoon with energy. Therefore, some people vividly say that taking a nap is equivalent to drinking half a pound of milk. But we should also pay attention to it well, otherwise it will be counterproductive.
The nap time is particular.
Don't sleep immediately after meals: generally, it is better to arrange the nap time to half an hour after lunch, and don't sleep immediately after meals. Because I just had lunch, my stomach is full of food, and my digestive function is in motion. At this time, taking a nap will affect the digestion of my stomach.
Don't take a long nap: 15~30 minutes is the most appropriate time for a healthy nap, and the longest time should not exceed 1 hour. If it takes too long, you will wake up with a slight headache and general weakness, and it is not easy to wake up at this time. It is better to extend it to 1~ 1.5 hours and have a complete sleep cycle. Moreover, taking a nap for too long can easily affect sleep at night.
