Sleep time is generally 8 hours, but if the quality of sleep is high, sleep less than 8 hours can also achieve a good rest effect.

Sleep quality is influenced by many aspects:

1. Environmental factors: whether the living bedding is comfortable, whether the environment is quiet, and whether the temperature and humidity of the space are appropriate.

2, psychological stress: during the day, the work pressure is high, and the brain thinks too much, which leads to a high degree of mental tension and cannot enter a relaxed state; And insomnia and dreaminess caused by mental illness.

3, physical health: pharyngitis, rhinitis and other diseases that affect breathing, digestive tract, spleen and stomach and other systemic diseases, as well as physical discomfort caused by other reasons, will make the body unable to enter a completely comfortable and relaxed state, affecting the quality of sleep.

Therefore, the most important thing is to adjust the mentality, keep the psychological pressure from being too great, strengthen exercise and ensure a good sleep quality, so that even if it is only a short rest, the energy can remain vigorous.
