What should I do if the weather is getting cold and dizzy?
In summer, the blood vessels of human body dilate, and the blood flow of skin will also increase. Organs with high oxygen consumption, such as heart and brain, have relatively sufficient blood supply. When the weather gets cold, human blood vessels will contract and brain blood flow will decrease. Oxygen in the human body is transported with blood, and the blood supply to the brain is reduced, which leads to insufficient oxygen supply to the brain, dizziness and headache, and also causes autonomic nerve dysfunction and insomnia symptoms. Some elderly people, or some patients with heart disease, asthma, bronchitis, etc. The ability to regulate the body declines. If the cardiopulmonary function is impaired, the inhalation and utilization of oxygen will be hindered, which is more likely to lead to hypoxia in the body.
Lack of oxygen will do great harm to human body. The heart, brain and lungs are big consumers of oxygen. Hypoxia can easily lead to the decline of other organ functions and induce diseases such as heart, brain and lung. Diseases of heart, brain and lung reduce the utilization rate of oxygen by organs themselves, make ischemia and hypoxia more serious, aggravate chest tightness, shortness of breath, dizziness, headache, and even induce angina pectoris, myocardial infarction and asthma. Only sufficient oxygen can effectively improve the immune ability of the body, thus avoiding and alleviating the occurrence of diseases. Therefore, people who often have dizziness and headaches in autumn need to pay attention to supplementing themselves with oxygen.
