1. Respiratory diseases
Viruses and bacteria are particularly active in cold winter and dry air, especially when there is little snow. In this case, especially the elderly, the body's resistance drops, and the respiratory mucosa is easily stimulated, leading to respiratory infection.
For elderly smokers, it is recommended to quit smoking, because the stimulation of smoking is more likely to cause respiratory diseases.
2. Heart disease
In winter, cold air can cause abnormal vasoconstriction, so the elderly are prone to serious consequences such as arrhythmia, angina pectoris and eventually myocardial infarction. The main manifestations of angina pectoris are chest pain and asphyxia. Some patients have unilateral toothache and upper limb pain. Emotional fluctuation is also an inducing factor of cardiovascular diseases. Therefore, the elderly must keep a calm mind and avoid emotional excitement. It is not advisable to be overjoyed or overjoyed.
3. Cerebral vascular diseases
In winter, due to the dry and cold climate, blood vessels will contract strongly, and the elasticity of blood vessels will deteriorate due to the aging problem of the elderly. When encountering cold air, blood vessels will suddenly contract, leading to insufficient blood supply, which is easy to cause some cerebrovascular diseases, such as cerebral hemorrhage or cerebral thrombosis, which is what we call "stroke".
The elderly should be careful to prevent the above three diseases according to their own physical conditions, and don't lose big because of small things.
