Because of the high pressure of work and life, many people can not sleep adequately in daily life. It is known to all that adequate sleep is an important way for people to relieve fatigue and regain energy. However, it does not mean that it is beneficial for people to sleep excessively long. The excessive sleep can seriously hurt the mental health and physical health of the human body. 

The regular life keeps a close relationship with the secretion of hormones inside the human body. If people sleep and get up regularly, the secretion of hormones will be stable. However, if people always sleep for a long time, the biological clock inside the human body can be seriously disturbed and the secretion of hormones can also be affected, which can decrease the physical immunity and induce various diseases. Therefore, it is necessary for people to pay attention to the sleeping time.

What’s more, the air inside the house is very dirty in the morning. According to the experts, the air contains a large amount of bacteria, fermented articles, carbon dioxide and dust. As a result, the absorption of the dirty air can easily hurt the respiratory system and induce various uncomfortable symptoms, such as cough, faucitis and dizziness. The memory and hearing can also be seriously affected. In addition, the poor-quality furniture can also release some toxic substances like formaldehyde to threaten the human health. In order to reduce the absorption of toxic air, people should control the sleeping time moderately.

At the same time, it is normal for people to feel hungry in the morning. The stomach and the intestines have already prepared to receive and digest food and secrete various kinds of digestive juice. If people do not get up in time, the normal functions of the stomach and intestines can be disturbed. After a long time, the gastric and intestinal mucous membrane will be destroyed and various diseases like gastritis and ulcer can also be caused. When people fall asleep, the metabolism can be decreased and the consumption of energy will be reduced at the same time. Because of the excessive sleep, the supplementation of energy will overpass the consumption. As a result, the energy will be accumulated under the skin in the form of fat to cause obesity. The obesity can further induce the heart disease, high blood pressure, diabetes and so on to threaten the human health.
