People may naturally lose weight in summer. In summer, due to many factors such as climate, it will affect people's diet and sleep. If the conditioning is not good, it will affect health and cause physical changes such as weight loss.

In summer, due to high temperature, vigorous metabolism, high energy consumption and excessive sweating, body fluids and other nutrients are easily lost. If you can't replenish nutrition and water in time, it will cause a negative balance of the body, leading to weight loss or emaciation. Excessive sweating in summer will reduce the secretion of digestive juice, affect the secretion of gastric acid, lead to decreased appetite and weakened digestive function. It is hot in summer, and the quality of sleep at night is easily affected.
