It's hot. Why aren't you hungry?

Because of sweating in summer, it is easy to cause imbalance of body fluid metabolism. The balance between water and electrolyte is an important factor to keep the internal environment relatively constant. Excessive sweating will lead to excessive loss of water, sodium ions and water-soluble vitamins (mainly vitamin B 1 and C), resulting in imbalance of water and salt metabolism and acid-base balance in the body. Due to a lot of perspiration and chloride ion loss, the chloride ion reserve necessary for the formation of gastric acid in the blood will be reduced, resulting in a decrease in the acidity of gastric juice; At the same time, drinking more water because of thirst will also dilute stomach acid. These changes will affect the digestive function and cause loss of appetite.

Chinese medicine also believes that summer humidity is high and the spleen and stomach are easy to get wet, so most people will lose their appetite. In summer, skin blood vessels expand due to heat dissipation, and gastrointestinal blood flow will be relatively reduced. Especially after eating a lot of cold drinks, gastrointestinal blood vessels will shrink sharply due to cold stimulation, blood flow will be further reduced, and digestive ability will naturally decline. In addition, the original digestive system diseases may be aggravated in summer, and if they belong to deficiency-cold constitution, they are more prone to indigestion at this time.

I don't feel hungry and it's not troublesome to eat, so I'm too lazy to eat, just don't want to eat.
