Fatigue and night sweats can be caused by various factors, including hormonal changes, medical conditions, overheating, overdressing, nightmares, tuberculosis, medication, low or high blood sugar or pressure, and strenuous late-night exercise. Proper treatment and lifestyle changes can help manage these symptoms.
Fatigue and night sweats can be caused by many conditions, including hormonal changes or imbalances, especially during menopause. Certain medical conditions or illnesses can also cause these symptoms, including the flu or other respiratory illnesses, such as pneumonia or bronchitis. Some forms of cancer can also cause such problems. These symptoms can also be caused by acquired immune deficiency syndrome (AIDS).
Sometimes the most obvious causes of symptoms are easily overlooked. If a bedroom is overheated or the room is particularly hot and humid, night sweats can be a common problem. Fatigue generally results from loss of fluids, therefore causing the body to lose essential electrolytes.
Overdressing in uncomfortable, heavy sleepwear can also lead to fatigue and night sweats. The best way to avoid problems caused by a hot environment is to use the air conditioning when necessary, or circulate the air with a fan and open the window for proper ventilation. Wearing loose, cool nightwear can also help.
When a person has recurring nightmares or frightening dreams, this too can lead to fatigue and night sweats. Some individuals may experience an increased heart rate during a bad dream and sweat. This can cause sleep deprivation or disrupted sleep, which can lead to fatigue.
Tuberculosis is a very serious bacterial lung disease known to cause fatigue and night sweats. This disease is contagious and is transmitted through human contact, coughing and sneezing. If left untreated, the disease can progress and cause irreversible damage or death. Most patients can be treated with medication.
There are several medications that can cause these symptoms. Acetaminophen, Advil and aspirin can cause them in some individuals. Antidepressants are also known to cause fatigue and night sweats. Some antibiotics can also produce these symptoms.
Low blood sugar or hypoglycemia can cause night sweats and fatigue. Weakness and fatigue are especially common for individuals suffering from hypoglycemia. Ensuring that sugar levels in the body are balanced and returned to an acceptable or normal range can help control these symptoms.
High blood pressure (hypertension) can cause these symptoms. High blood pressure can also lead to other more serious complications if left untreated. The best way to control this condition is to monitor your blood pressure and take medications as prescribed by a doctor. Occasionally, high blood pressure medications can cause night sweats.
In some individuals, participation in strenuous late-night or evening exercise can produce fatigue and night sweats. This can usually be prevented by exercising early in the day and cooling down. A positive step in managing fatigue could be finding time to relax before bed.
