If the body temperature is 34℃, it is necessary to rule out any measurement error. The normal body temperature is between 36-37.2℃, and a body temperature below 35.5℃ is considered a sign of hypothermia. If the body temperature is 34℃, we need to observe the general condition of the patient, whether there are any symptoms other than dizziness, and whether there are any endocrine problems, such as hypothyroidism. In the elderly, patients with low basal metabolic rate, poor resistance and wasting are prone to hypothermia. As long as the patient’s general condition is fine, and he/she is eating, sleeping, and urinating and defecating normally, there is no major problem. Regular observation of body temperature and related indicators such as electrolytes, kidney function, liver function, blood count, etc. is needed.
