Why do people get thinner in summer?

Summer is the second of the four seasons and the hottest season in the northern hemisphere. China is used to long summer as long summer, and meteorological summer will be postponed to long Xia Hou for about 25 days. The ancients counted April, May and June of the lunar calendar as summer. Today, people regard June, July and August in the solar calendar as summer.

In summer, the body consumes a lot of water, and the body tissues already contain a lot of water. At this time, with the consumption of water, the body will naturally lose weight.

The main reason why the body becomes thinner in summer is that the digestive function is affected. The summer heat is pressing, and the appetite of ordinary people is not very good. This is because heat dulls people's nerves, relaxes stomach muscles, weakens contractility, and has poor digestion ability, which affects food digestion and nutrient absorption. If you eat a lot of nutrients but don't supplement them, you won't gain weight naturally.

In addition, hot summer makes people feel depressed, sweat more, drink more water, eat more fruits and eat less. Old people often say, can fruits, plums and dates be eaten as meals? However, people are too hot to have an appetite, so they can only eat some fruits and vegetables to satisfy their hunger.

In addition, in summer, the days are long, the nights are short, the heat is unbearable, and people can't rest well at night. Drinking more water to dilute gastric juice and eating fruits and vegetables is easy to affect people's eating on time, which can affect people's digestive function and thus affect the absorption of nutrients. Many friends are still fat in autumn and winter, but they are obviously thin in summer, which is what people often call "bitter summer".

Bitter summer means that after entering the summer, due to the rising temperature, the appetite decreases, and the food intake is significantly reduced compared with other seasons, accompanied by low fever, physical fatigue, listlessness, low work efficiency, weight loss and other phenomena.

In fact, bitter summer is not a disease, but severe patients can take vitamin C and vitamin B under the guidance of doctors, which is beneficial to regulate autonomic nerve function and eliminate the symptoms of bitter summer. In fact, this is why people lose weight in summer.

In summer, when people lose weight, they need to supplement nutrition, but they must not eat too much hot food, such as mutton. Modern medicine believes that the hot stimulation in summer makes the nerve center in a state of tension, and the activity level of endocrine glands has also changed, leading to indigestion, loss of appetite and unwillingness to eat.

Therefore, it is best to eat more light and less oily food in summer, which will be easier to digest, while too greasy food is not suitable, because greasy food will reduce gastric juice secretion and slow down gastric emptying.

Being in the humid season in summer, eating more foods that clear away heat and damp will help prevent the body from being troubled by damp heat, which is quite helpful for relieving summer heat and promoting fluid production. Relatively speaking, it is better to eat less when frying hot dried vegetables.
