Can drinking ice beer in summer clear away heat and quench thirst?

　　There is no scientific basis for cold beer to relieve heat and quench thirst. The best drinking temperature of beer should be around 8 degrees Celsius, and the minimum should not be lower than minus 1.5 degrees Celsius, which is the freezing point of beer. The temperature of the beer in the freezer is much lower than the freezing point of the beer, which not only affects the color and taste of the beer, but also causes a loss of nutrients.

　　In the hot summer, drinking 7-8 bottles of cold beer at one time will cause the temperature of the gastric mucosa to drop sharply, which can easily cause stomach pain and indigestion, and even induce cold . In addition, after drinking cold beer, the volume of the gastrointestinal tract expands, causing the stomach wall to expand, causing painful ulcer attacks and even acute perforation, leading to dangerous peritonitis.

　　For this reason, the following groups of people are strictly prohibited from drinking cold beer:

　　infants, elderly , weak people and some patients with deficiency and cold, cardiovascular and cerebrovascular patients, chronic gastritis, ulcer patients, pregnant women and intestinal disease patient.
