4. Obesity


As if menopause weren’t difficult enough, studies show that obesity can increase menopause symptoms and worsen night sweats. While night sweats can affect any individual of any size, a higher body mass index (BMI) may lead to more frequent hot flashes and night sweats. Maintaining a cooler bedroom temperature at night and running a ceiling fan or keeping a fan on your nightstand can help decrease nighttime sweating.

3. Sleep Disorders

Sleep Disorders

Obstructive sleep apnea syndrome is a disorder in which a person repeatedly stops and then restarts breathing while sleeping. This apnea is caused when the muscles of the throat relax and block the airway. Your bed partner may notice symptoms such as snoring and episodes when your breathing stops. Other symptoms are daytime fatigue, a dry mouth and throat upon awakening, irritability, and night sweats. Risk factors for obstructive sleep apnea syndrome include obesity, enlarged tonsils or adenoids, high blood pressure, and chronic nasal congestion.

2. Stroke


The International Hyperhidrosis Society lists stroke as one neurological disorder that can cause night sweats. Hyperhidrosis refers to excessive sweating, which can either be caused by primary hyperhidrosis or secondary hyperhidrosis. Primary hyperhidrosis is excessive sweating not caused by an underlying medical condition. Secondary hyperhidrosis is excessive sweating that is caused by another medical condition. Stroke is a neurological condition that may cause hyperhidrosis and excessive nighttime sweating. Other neurological conditions that can cause night sweats are autonomic dysreflexia and autonomic neuropathy.

1. Thyroid Disease

Thyroid Disease

Hypothyroidism occurs when the thyroid gland does not produce the necessary levels of thyroid hormones needed for normal body functions. Problems with body temperature regulation can be one effect of low thyroid hormone levels. Hashimoto’s thyroiditis is a form of hypothyroidism in which the body’s immune system attacks the thyroid gland. Hypothyroidism may also occur when medications interfere with thyroid function. Other causes of hypothyroidism are the removal of the thyroid, inappropriate levels of dietary iodine, and pituitary disorders.
