people are used to drinking beer in summer, but they are not interested in beer in winter. It is not comprehensive to treat beer as a drink to relieve summer heat and quench thirst. In fact, drinking beer in winter is more valuable than in summer. In winter, due to the stimulation of cold, the human body consumes a lot of heat energy, and there are often low-heat chills, such as cold limbs, pale face, tired expression, frequent urination, and even trembling. Because beer contains sugar and alcohol, they are the main sources of high calories in beer. It is determined that every liter of beer can produce 76 calories, which is equivalent to 1/3 of the daily calories needed by adults. Therefore, drinking beer in winter can increase human heat energy and improve the body's resistance to cold. Hops in beer have the functions of strengthening the heart, diuresis, antisepsis and sterilization. Drinking hot beer can increase the beer element in hops, which has a good auxiliary treatment effect on lung disease and lymphotuberculosis, and can also accelerate blood circulation, improve peripheral circulation and prevent frostbite. Drinking beer in winter can be heated, and the temperature can depend on the temperature. Generally speaking, the suitable temperature for drinking beer is between 12 and 15℃. When the beer can't reach this temperature due to the cold weather, the bottle can be soaked in warm water before drinking to reach the appropriate temperature. But the water temperature should not be too high, because the temperature resistance of beer bottle glass is limited. If it is too high, the bottle will burst and even explode.
