Sleep can be divided into shallow sleep and deep sleep Usually, a short nap is a light sleep, which can promote the recovery of mental state and is more conducive to afternoon activities and work. It is generally recommended to take about 30 minutes. If the nap time is too long, it will change from shallow sleep to deep sleep. After deep sleep, metabolism slows down and blood flow slows down. When you wake up, the blood flow speed will suddenly increase, and symptoms such as palpitation, dizziness and fatigue will appear, making it difficult to enter the normal working state in a short time.
In addition, it is not advisable to sleep immediately after meals, so as not to slow down the blood and affect the digestive function of the stomach. Try not to sleep on your desk, so as not to oppress your stomach. Conditional suggestions to form a good habit of taking a lunch break will help improve work efficiency.
