What are the hazards of eating cold drinks in hot weather?

Many people think that eating cold drinks in hot weather can relieve summer heat and thirst, but in fact, eating cold drinks has no effect on relieving summer heat.

Most of the water molecules in cold drinks are in polymerization state, and the molecular groups are large, so they are not easily absorbed by cells. Cold drinks make gastrointestinal blood vessels contract rapidly, and the water you drink accumulates in the gastrointestinal tract, which can also lead to abdominal distension and discomfort.

However, there are many molecules in hot drinks, which can quickly penetrate into cells and replenish water, so drinking hot water or hot tea is better for relieving summer heat and thirst.

Eating cold drinks is easy to hurt your stomach.

The temperature of cold drinks is generally 20℃-30℃ lower than that of the stomach, which easily stimulates the gastrointestinal tract, causes vasoconstriction and mucosal ischemia, weakens the secretion of digestive juice, affects the bactericidal function of the gastrointestinal tract, causes spasmodic pain, and even causes intestinal infection, loss of appetite, abdominal pain and diarrhea.

Chinese medicine also believes that the yang of the human body moves to the body surface in hot days, and the spleen and stomach are cold. Eating too many cold drinks will damage the yang of the spleen, which is easy to cause the invasion of exogenous pathogens. A cold will damage the spleen, ranging from abdominal pain and diarrhea to nausea and vomiting.

In addition, women should not eat too many cold drinks during menstruation, which may easily lead to poor menstrual flow, reduced flow, and even dysmenorrhea and menopause.

Eating too many cold drinks can easily reduce human immunity and increase the risk of illness.

Especially, if children eat too many cold drinks, the oral cavity and throat will be in cold stimulation for a long time, and the local blood vessels in the throat will contract, causing diseases such as upper respiratory tract infection and allergic rhinitis.

In addition, drinking a lot of cold drinks will also lead to poor ventilation of sweat pores and difficulty in heat dissipation, which will lead to heatstroke.

Excessive drinking of cold drinks with high sugar content is prone to dental diseases.

Cold drinks, such as ice cream, ice milk and iced fruit juice, often contain high sugar content, and excessive intake will increase the risk of tooth decay.

In addition, some people drink hot coffee, hot milk and so on. Use it immediately after drinking cold drinks, and the change of hot and cold can easily stimulate its teeth, causing dentin hypersensitivity and toothache.
