How to relieve fatigue by taking a nap in spring

1. Benefits of taking a nap

Lower blood pressure. For people whose blood pressure is high due to work pressure, taking a nap can help lower blood pressure.

Improve memory. Studies have found that taking a nap can significantly improve a person's energy and alertness; a study by the University of Düsseldorf in Germany showed that taking a nap can not only eliminate fatigue, but also improve memory.

Improve immunity. Taking a short nap at 1pm can effectively stimulate lymphocytes in the body, thereby enhancing the activity of human immune cells.

2. Not all people are suitable for naps

For ordinary people, a 15-30 minute nap can improve the quality of sleep at night.

First, the sleep cycle is divided into five stages. The first two stages are relatively light sleep , the third and fourth stages are deep sleep , and the last stage, the rapid eye movement stage , is the stage when dreaming begins.

The first two stages occur within 30 minutes . If you wake up in the first stage, you will feel as if you have not slept. In the second stage of sleep, the brain begins to integrate and process declarative memory and consolidate memory .

Therefore, a reasonable nap is to start from the first stage of sleep, enter and stay in the second stage, and avoid entering the deep sleep stage.

Second, if you sleep too long, the central nervous system of the brain will cause the capillaries in the brain tissue to close for a long time, and the body's metabolic process will slow down. After waking up, the various tissues and organs of the human body will be forced to wake up, and you will feel tired all over .

For insomniacs, napping will reduce the driving force for nighttime sleep, so napping is not recommended. This is the reason why "I have insomnia, why doesn't the doctor let me take a nap?" It is a way to improve insomnia by reducing the non-sleeping time spent in bed to improve sleep efficiency.

3. Tips for taking a nap in spring

The nap time should not be too long, and it is best to control it within 30 minutes. If people suddenly wake up in the deep sleep stage, there will be insufficient blood supply to the brain, which will make people feel very uncomfortable. This discomfort will last for about 30 minutes before gradually disappearing, so the nap time should not be too long.

It is best to sleep lying flat. Many people are used to sleeping on the table, but this will compress nerves and blood vessels, thus affecting the quality of sleep. Therefore, if you have plenty of time at noon, it is best to find a place where you can lie down and have a good sleep, and it is best to cover yourself with something.

You might want to change your nap time to before meals. Many people have had this experience: after lunch, it is difficult to fall asleep because you are too full. Even if you fall asleep, the quality of your sleep is not high, and you will feel dizzy and weak after waking up. If you have this problem, you might want to change your nap time to before meals. Studies have shown that in spring, taking a nap before meals can relieve fatigue better than taking a nap after meals.
