Eating chocolate can help to relieve some people from altitude sickness. However, most of the people who have plateau reaction can’t be relieved by eating chocolate, because chocolate only replenishes the sugar in the body, which will relieve the discomfort caused by hypoglycemia, while the real plateau reaction is caused by the lack of oxygen. It is best to relieve it by inhaling oxygen. At the same time, you can also take drugs to relieve, including rhodiola, inosine and salvia, etc. These drugs can increase the body’s oxygen tolerance, which will greatly relieve the discomfort caused by the lack of oxygen due to plateau reaction. However, the main thing in the plateau area is to pay attention to personal protection, avoid excessive exercise, physical exertion, also avoid overeating, maintain a calm state of mind and enough sleep can effectively prevent and relieve plateau reaction.
