Drenching the pillow with night sweats:

People sweat all the time, but they usually sweat in such small quantities that they don’t notice it. A warm room temperature, excessive clothing or exercise will of course increase sweating, and that is normal.

However, if you suffer from excessive night sweats and find your pillow, shirt or bedding drenched in sweat, then that might be a sign of a problem that you need to attend to. Read on to learn more.

Nighttime sweating is due to overactive sweat glands. People typically have a higher body temperature at night – so some degree of sweating at night is normal.

Hyperhidrosis is the medical term for excessive sweating. It annoys those who suffer from it because of embarrassment or frequent awakenings, which can lead to insomnia.


There are many reasons why people suffer night sweats.
Here is a list of potential causes:

Perimenopause: This is probably the most common cause of night sweats, which are sometimes referred to as hot flashes. It’s the time in a woman’s life before menopause, when her hormones begin to change. It is part of the natural transition in a woman’s life and is not dangerous, though it’s distressing at times and can drive women crazy.

Pregnancy: Pregnant woman also suffer from night sweats because of hormonal changes.

Diabetes: Low blood sugar (hypoglycemia) can cause night sweats; the condition is seen in diabetics who take insulin.

Hyperthyroidism: This condition, which involves an overactive thyroid gland, can cause night sweats.

Primary hyperhidrosis: This is a condition in which your body makes excess sweat because of a genetic reason. It usually starts at a younger age.

Still more potential causes include:

  • Sleep apnea syndrome
  • Nightmares
  • Neurological conditions such as stroke, spinal cord injury and neuropathy
  •  Infections, including tuberous sclerosis (TB) and HIV
  • Fever
  • Certain cancers — Lymphoma is commonly associated with night sweats.
  • Medications: Antidepression medications such as bupropion (wellbutrin) and venlafaxine (effexor); stimulants such as Ritalin or Dexedrine; and prednisone
  • Alcohol
  • Stress or anxiety

Tips on relieving night sweats:

  • Talk to your doctors and run some tests to make sure there is no serious condition involved, such as the ones listed above.
  • Make sure to replace the water and minerals lost during the day if you are excessively sweating.
  • If you can find the cause, treatment of that cause can eliminate the night sweats.
  • Wear light-fitting clothes that soak up the moisture, perhaps cotton.
