Ice water is the most popular drink in summer. It is more suitable for people who sweat a lot or who have just done some exercise. Young people and many children love to drink ice water. However, after pregnancy, you should try not to drink ice water, as it will affect the healthy development of the baby. Normal people will also feel unwell after drinking ice water. Phenomenon 1: Headache after drinking ice drinks When you suddenly drink an ice drink or ice cream, you may experience a short-term headache. This is mainly because the sudden hot and cold stimulation of the capillaries in the sinus area causes rapid contraction and expansion, thereby stimulating the pain receptors in the upper palate, and the pain is transmitted to the brain. Because the pain in the upper palate is transmitted through the same pathway as the pain in the face, the brain mistakenly thinks it is coming from the forehead. However, this pain is very short-lived and will not occur as long as you avoid drinking large amounts of cold drinks. If you have a severe headache, you can put your tongue against the roof of your mouth to provide some relief. Phenomenon 2: Sudden myocardial infarction caused by drinking cold drinks Many documents have shown that heart patients suffer sudden myocardial infarction after drinking large amounts of cold drinks. This is because cold drinks will stimulate the coronary arteries after entering the human body, causing the narrowed blood vessels to further contract, and acute myocardial ischemia can induce myocardial infarction. Although this only applies to patients with poor heart function, it does not mean that there is no harm in drinking ice water for healthy people. ① After drinking a lot of ice water, the body's pores cannot vent smoothly, the body's heat cannot be evacuated normally, and it is more likely to cause heatstroke. ②Ice water is cold in nature and once it is absorbed by the body, it can easily cause gastrointestinal cramps. Pregnant women are a special group of people. They are carrying babies in their bellies and should be more cautious in their diet and lifestyle habits. Since ice water is harmful to healthy people, it is even more harmful to pregnant women. Experts say: Even in the hot summer, pregnant women should not drink ice water, as it may cause gastrointestinal discomfort at the very least, and even premature birth at the worst. |
