After lunch, the human body to ensure the digestion and absorption of food, most of the blood flow to the digestive system, the brain’s blood is relatively reduced, plus after a morning of work or study, brain cells are also in a state of fatigue, so there is a sense of drowsiness.
This midday sleepiness is the normal sleep and wakefulness of the biorhythms of the law of performance, through the nap to regulate, nap can compensate for the lack of sleep at night, can make the human brain and body systems are relaxed and rest, more conducive to the afternoon, evening work or study.
In addition, napping can also protect the brain and relieve tension. When sleep, not only the nerve cells of the cerebral cortex is protected by inhibition, rest, while all parts of the body also get a comprehensive rest, the whole body muscle relaxation, due to the activities and physical energy consumed can gradually recover, the body’s internal organs can be calm and more regular work.
How to nap more healthy
- ★ light activity after waking up, after the nap to slowly stand up, and then a glass of water to replenish the blood volume, dilute the blood viscosity, do not immediately engage in complex and dangerous work.
- ★ Do not eat greasy food before going to bed and do not eat too much. Greasy food will increase blood viscosity, aggravate coronary artery lesions, increase the burden of stomach digestion, affecting the quality of the lunch break.
- ★ If you want to nap, to develop the habit of regular daily rationing. The best time to take a nap is 8 hours after waking up in the morning, and 8 hours before going to bed at night, which is the middle of the day’s activity time. Even if you don’t feel sleepy at that time, you can take a little break instead of drinking coffee as a brain-awakening soup.
- ★ healthy nap to 15-30 minutes most appropriate, if more than 30 minutes, the body will enter the deep sleep period is not easy to wake up, it is better to extend to 1 ~ 1.5 hours to complete a whole cycle of sleep. Nap for too long, just get up half an hour will have a slight headache, general weakness, which is caused by “sleep inertia”. At this time do not expect to immediately wake up, after an hour of buffer to return to normal.
- However, this longer nap is only applicable to supplement the previous night’s sleep deprivation, the real health nap should not exceed 30 minutes, otherwise it is easy to disrupt the physiological clock, affecting the normal late sleep.
- ★ nap habits to be consistent, because nap habits are irregular will also disrupt the physiological clock, affecting the regularity of the evening sleep. For example, dragging until late in the evening to sleep, not only does not help health, but also delays the time to sleep at night.
