According to Dr. Huynh Tan Vu, University of Medicine and Pharmacy Hospital, Ho Chi Minh City – Campus 3, in the human body there are two opposing autonomic nervous systems: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system increases sweat secretion, while the parasympathetic nervous system reduces sweat secretion. When the sympathetic nervous system is active, it stimulates the sweat glands to secrete more sweat.
Sweating is a natural response of the body to fight against increased temperature. However, there are times when the body still sweats when not active, especially at night, which can be a sign of some dangerous diseases.
Cancer
According to doctors, night sweats are an early symptom of cancer, usually lymphoma. If you notice excessive sweating at night and some signs such as sudden weight loss and fever, you should quickly go for a health check.
Infectious Diseases
A rather dangerous infectious disease is tuberculosis. These patients often sweat more at night than normal people.
In addition, night sweats are also a sign of some dangerous diseases such as endocarditis (heart valve inflammation), osteomyelitis and can be a symptom of the disease of the century HIV (AIDS).
Premenopausal
Pre-menopause in women can start from 40. At this time, due to hormonal changes in the body, women can sweat. Many patients feel more anxious, have insomnia, stress and many areas of red skin.
However, this is not a cause for concern. It is best to provide your body with enough lost water and use a soft, dry towel to wipe away sweat to avoid skin infection.
Hypoglycemia
Many people who are supported by insulin and diabetes medications may experience night sweats and other discomfort. In addition, the sweat glands depend on the central nervous system, so low blood sugar also affects the activity of the nerves, leading to sweating.
The patient also has other symptoms such as: arrhythmia, tremors in hands and feet, dizziness, loss of consciousness, and possibly even coma.
Fattigue
Obese people tend to have higher body temperatures than people of normal weight, because their subcutaneous fat is too thick. This group tends to sweat more even when resting. Therefore, obese people should choose a weight loss diet to prevent the risk of disease.
Stress and chronic tension
Stress from work and daily life follows you into your sleep. This can inhibit nerve activity, and some people even have “nightmares” that cause sweat glands to work harder.
Additionally, feelings of excitement, anxiety, and stressful situations release adrenaline into your circulatory system, causing you to sweat more.
