Clinical information about night sweats

As mentioned earlier, night sweats are a type of generalized hyperhidrosis (excessive sweating). It's sometimes referred to as nocturnal hyperhidrosis.

This type of excessive sweating occurs while a person sleeps, and they may wake up because it can soak and dampen the bed sheets and bedclothes. This can be annoying because a person will likely have to repeatedly change their bedsheets and bedclothes if the night sweats are constant.

Night sweats are not inherently harmful and can occur without apparent cause (idiopathic night sweats), but they can also indicate an underlying condition. Here are some underlying causes of night sweats:

• Sleep apnea
• Anxiety
• Stress
• Hypoglycemia (low blood sugar)
• Hyperthyroidism
• Tuberculosis
• Endocarditis
• HIV
• Menopausal and female climacteric states
• Enlarged lymph nodes (lymphoma)
• Taking certain medications
• Obesity
• Fever from various infections
• Headache disorders (in some cases)
• Lack of expected normal physiological development in childhood and adults
