Because of the hot climate in summer, you can wait for the summer heat to dissipate, the human breath is also relatively calm when you go to bed, time is a little later than the other seasons, but it should not be too late, generally around 11 p.m., the ancients advocate of the midday nap very much in line with the summer health.

Sleeping time for different ages:

Enough sleep is a guarantee of a long and healthy life, and the best sleeping time should be determined according to different ages, genders, physiques, personalities, and environmental factors. We all know that the younger the need to sleep longer and more often, which is determined by the law of human growth and development. Infants and young children in the most exuberant period of growth, there must be enough sleep; adolescents are developing physically, but also bear the heavy task of learning, and therefore also need more sleep time; some people think that the elderly sleep time can be less, on the contrary, the elderly need to sleep more than young people. Because the old man gas and blood two losses, "camping gas decline less and Wei gas within the logging", so there is "daytime is not fine, the night is not close" phenomenon, that is to say, during the day there is no spirit, but at night can not sleep, but this does not mean that the physiological need to reduce the amount of time to sleep. On the contrary, due to the poor quality of sleep, easy to wake up, but should be appropriate to increase the time of sleep, especially the nap is important. Ancient health practitioners said, "less sleep is a big problem for the elderly." The "ancient and modern" also believes that the elderly should be "in case of sleep on the pillow".

Sleeping time is also more or less related to gender, usually women sleep longer than men on average, and modern research suggests that it may be related to differences in sex hormone secretion. In general, the optimal daily sleep time is 14 to 15 hours for infants, 12 hours for preschool children, 10 hours for elementary school students, 9 hours for secondary school students, 8 hours for college students, 8 hours for adults, and 9 to 10 hours for the elderly.
