Heaven and earth began to meet and everything appeared.

The long summer on May 5th is a solar term, symbolizing the beginning of summer.

The ancients believed that spring is the harmony between heaven and earth, and plants germinate; Summer is the beginning of heaven and earth, and everything is beautiful. The atmosphere is tense and the weather is sunny. Summer is the best time for interaction between heaven and earth.

The summer temperature is high, and the human body loses a lot of water, so it must be replenished in time. Besides drinking more water, it is also a good choice to eat more vegetables rich in water. Among the vegetables rich in water, the most recommended ones are melon vegetables, such as wax gourd, cucumber, bergamot, loofah and pumpkin.

After the long summer, the days are getting longer and the nights are getting shorter and shorter. Sleep at this time should be relatively "late to bed and early to get up" to accept the breath of heaven and earth, but we should still pay attention to "nap", especially proper nap, to ensure full mental state and sufficient physical strength.

At this time, the diet should be light, with low-fat, digestible, fiber-rich vegetarian diet as the mainstay, and eat more fruits and vegetables and coarse grains. Usually you can eat more fish, chicken, lean meat, beans, sesame, hawthorn, bayberry and so on. Eat less animal offal and fat and less salty food.

Summer is also a high incidence period of gastrointestinal diseases such as bacillary dysentery, acute gastroenteritis and food poisoning. Pay attention to food hygiene, drink more warm water and eat less cold drinks.
