Night sweats or nocturnal hyperhidrosis are repeated episodes of severe perspiration that make you wake up in the middle of the night to find your clothes and bedding soaked up, even if the room temperature and weather is normal and not too hot.

Occasional occurrences of night sweats when the weather is hot or you may be sleeping under too many blankets are normal and not a sign of any medical problem. Severe and constant night sweat could be a symptom of some serious underlying medical conditions.

Let’s understand the possible reasons that may be making you sweat constantly in the night.

  • MENOPAUSE

The hot flashes that accompany menopause may occur at night, causing night sweats.

  • OBSTRUCTIVE SLEEP APNEA

A condition that causes interrupted breathing during sleep.

  • MEDICATIONS

Certain medications such as anti-depressants, aspirin and other psychiatric drugs can cause night sweats as a side effect.

  • ALCOHOL & DRUG ABUSE

 Consuming alcohol in excess or use of drugs, especially heroin can make you sweat in the night.

  • HYPOGLYCAEMIA

 Low blood sugar can cause night sweats among those who take insulin or oral diabetes medications.

  • INFECTIONS

Tuberculosis is one of the most common infections that is associated with night sweats. Other infections like endocarditis, osteomyelitis, abscesses and even HIV/AIDS can contribute to night sweats.

  • CANCER

Night sweats are one of the early sign and symptom of certain cancers, especially lymphoma or leukaemia.

  • HORMONAL DISORDERS

 Sweating or flushing can be noticed in the case of several hormone disorders, including pheochromocytoma, carcinoid syndrome, and hyperthyroidism.

  • IDIOPATHIC HYPERHIDROSIS

Idiopathic hyperhidrosis is a condition wherein the body chronically produces too much sweat without any identifiable medical cause.

Night sweats are usually harmless but if you notice the following signs then it’s time to see a doctor:

  • If these night sweats happen on a regular basis
  • Interfere with your sleep
  • Accompanied by fever, weight loss, pain, cough, diarrhoea
  • Happen several months or years after menopause

If you notice these above signs along with night sweats, consult a doctor to find out about any underlying medical condition.
