Will altitude sickness be more severe in winter?

　　The plateau is covered with snow in winter, attracting many travelers, but the low temperature environment makes many people worry that altitude sickness will intensify. Is altitude sickness really more severe in winter? How to replenish energy during plateau travel?

Will altitude sickness be more severe in winter?

　　Altitude sickness may be more severe in winter, and the core reason is related to the physical burden caused by low temperature. In winter, the oxygen content of plateau air is lower than that of plains. The low temperature also stimulates the body to constrict blood vessels, leading to increased blood circulation resistance. The heart needs to work harder to maintain oxygen supply, which can easily aggravate dizziness, shortness of breath and other reactions. At the same time, cold will cause the body to consume more calories to resist the low temperature, temporarily reducing immunity, and making the discomfort more obvious. However, individual differences are large, and the reaction of people who are adaptable and keep warm may not be obvious.

How to replenish energy during plateau travel

　　1. Choose high-carbohydrate foods

　　Carbohydrates such as rice, noodles, and steamed buns can be quickly converted into energy and have little digestive burden. They can be consumed frequently as staple foods to provide basic power for the body.

　　2. Eat an appropriate amount of high-quality protein

　　High-quality proteins such as eggs, fish, and lean meat can maintain muscle function and enhance body tolerance, but the amount needs to be controlled to avoid excessive increase in gastrointestinal digestion pressure and increase the burden on the body.

　　3. Supplement high-energy snacks

　　Carry snacks such as chocolate and nuts with you and eat them in small amounts between activities to quickly replenish calories, relieve fatigue, and avoid discomfort caused by lack of energy.

　　4. Drink more warm water

　　The air on the plateau is dry and the body loses water quickly. Frequent drinking of warm water is required to keep the respiratory tract moist, promote metabolism, and avoid dehydration aggravating the reaction.

　　5. Avoid foods high in oil and sugar

　　Fried foods, sweet pastries, etc. are slow to digest and will take up a lot of energy in the body for digestion. They may also cause gastrointestinal discomfort and should be avoided as much as possible in a plateau environment.

　　Although traveling on plateaus in winter requires increased vigilance, it can be effectively dealt with by keeping warm and replenishing energy. Climbing heights gradually and avoiding strenuous exercise can also help the body better adapt to the plateau environment and enjoy the fun of travel.
