Feeling hot but not having a fever

Everyone knows that when you have a fever, your body will feel hot, especially your head. You may also have symptoms such as headache, general weakness, and fatigue. However, some people feel that their body is hot, but after measuring their body temperature, they do not have a fever. However, they still feel very hot all over. What may be the reasons for this situation? Below, I will introduce several situations that may cause your body to feel very hot but not have a fever.

1. Body heat dissipation

As the temperature rises, the body's blood flows out of the body surface in order to dissipate heat, causing relative ischemia of the internal organs. That's why people feel drowsy, weak, and have low blood pressure. At this time, you should replenish your Qi and blood to treat low blood pressure. Traditional Chinese medicine believes that one should nourish Yang in spring and summer. In spring, people should replenish Yang. You can take Qi-invigorating pills appropriately, and the symptoms of fever and dizziness you feel will disappear.

2. Rheumatic fever

Rheumatic fever is a systemic, non-purulent disease of connective tissue associated with group A R-hemolytic streptococcal infection. It was once one of the major diseases that endanger the life and health of school-age children and adolescents. It can affect the heart, joints, central nervous system, and subcutaneous tissue, but is most obvious in the heart and joints. Clinical manifestations include carditis, annular erythema, arthritis, chorea, and subcutaneous nodules. The lesions may be acute or chronic with recurrent attacks, and may leave behind heart valve lesions to form chronic rheumatic heart valvular disease. People with rheumatic fever may feel hot but not have a fever.

3. Colds cause internal heat

It is possible that a cold has caused internal heat in the body. A body temperature not exceeding 37.5 is not considered a fever. It may be a low fever. It is recommended that you go to the hospital for a routine blood test. If you have a cold, you must pay attention to rest, ensure adequate sleep, eat a light diet, take antibiotics and antiviral drugs, and drink plenty of water. You will recover in about a week, so don't be too nervous.

4. Autonomic dysfunction

If you have a fever but your temperature is not high, you may need to consider that it is caused by autonomic nervous system dysfunction. If it is accompanied by symptoms of headache, you need to rule out organic diseases that can cause headaches, such as migraine, trigeminal neuralgia, cerebral arteriosclerosis, cervical spondylosis, etc. It is recommended to go to the hospital for treatment, combine specific symptoms, signs, and relevant examination results to determine the cause, and give active treatment to the cause.
