How is dizziness and vomiting on a hot day?

When the weather is hot, the human body is affected by high temperature, and it is prone to various discomfort symptoms, among which dizziness, nausea, vomiting and other discomfort symptoms are very common. How is the weather hot, dizzy and disgusting? This is mainly due to the adverse effects of high temperature on human metabolism, which easily causes various discomfort symptoms. Let's learn more about the reasons why high temperature weather has adverse effects on human body.

1, the cause of dizziness

Under the influence of high temperature environment, blood vessels will contract. In this state, people's blood pressure will drop, and there will be insufficient blood supply to the brain. Moreover, due to the influence of heart function, the nutritional function needed by the brain will be insufficient, so there will be discomfort symptoms such as dizziness and pallor. In this case, it is necessary to go to a cool or ventilated environment as soon as possible to lower the body temperature and eliminate discomfort.

2. Causes of nausea

When the ambient temperature is high, the body temperature will also rise, and then the human body will cool down through sweat. In this state, the human body will consume a lot of salt and other minerals. If sweating is serious, it will lead to abnormal endocrine function of human body. Therefore, the digestive function of the stomach will also be affected, which is prone to indigestion. Moreover, in this high-temperature environment, microorganisms are very active, which is easy to ferment food in the stomach and intestines, which will stimulate the stomach and intestines, and then there will be discomfort symptoms such as nausea, abdominal distension and abdominal pain. In this case, it is also necessary to go to a cool place as soon as possible to cool down and avoid heatstroke.

3. Preventive measures

When the weather is hot, the human body will secrete a lot of sweat to cool down, and when sweating, it will take away a lot of minerals and salt. Therefore, after sweating a lot, you should not only replenish water, but also properly supplement minerals such as salt. When the weather is hot, if you have discomfort symptoms such as dizziness, nausea, pallor, general fatigue and fever, you'd better leave the high-temperature area as soon as possible and cool down, otherwise you are prone to heatstroke symptoms, and even life-threatening in severe cases.
