The condition of feeling cold in summer may be related to the individual’s physical constitution. Some patients who are usually malnourished or lack the necessary physical exercise, have poorer physical fitness and a lower basal metabolic rate, are prone to feel cold. Patients may also experience a lower basal body temperature and cold hands and feet. In addition, feeling cold in summer may also be caused by a viral cold. If a patient with a viral cold may have a fever, the patient may have cold hands and feet, chills and chills when the body temperature is relatively high. In addition, patients suffering from hypothyroidism may have low basal body temperature and feel cold because their basal metabolic rate also decreases. So when this happens, first of all, you should pay attention to proper exercise, and secondly, you should strengthen nutrition, enhance physical fitness and improve immunity. If the patient is accompanied by other symptoms, further examination is needed to clarify the diagnosis and provide targeted treatment according to the cause.
