Patients with low body temperature are prone to catching colds. These patients generally exhibit physical weakness and poor resistance, making them more susceptible to other diseases. Therefore, patients with low body temperature should first go to a hospital for further related examinations, such as blood routine tests, liver and kidney function tests, thyroid function tests, adrenal cortex function, and urinalysis. Once the condition is diagnosed, appropriate measures should be taken based on the results to alleviate the condition. Also, for those with a physically weak constitution and low body temperature, it is important to strengthen exercise, enhance nutrition, and improve physical fitness in order to reduce the occurrence of illnesses.
