Moreover, although iced drinks will bring temporary comfort, drinking them in large quantities will lead to poor ventilation of sweat pores, difficulty in heat dissipation, and accumulation of residual heat, which will easily lead to heatstroke.
The temperature of iced drinks, ice water and cold drinks is generally 20℃ to 30℃ lower than that in the stomach. A large number of cold drinks enter the body, which easily stimulates the gastrointestinal tract, causing vasoconstriction and mucosal ischemia, thus weakening the digestive function and bactericidal power of the gastrointestinal tract, causing spasmodic pain and even abdominal pain and diarrhea.
For the elderly, especially those with cardiovascular diseases, drinking ice water and ice drinks will not only cause stomach discomfort, but also cause cerebral vasospasm, which may lead to angina pectoris, so the elderly must not drink ice water.
In addition, people who exercise in summer should not drink iced drinks, because most of the blood in the body is concentrated on the body surface during exercise, and the digestive system is temporarily anemic. After drinking iced drinks, it will strongly stimulate the anemic gastrointestinal tract, make blood vessels contract and aggravate anemia.
