Why Do People Get Night Sweats During Withdrawal?

When people sweat a lot, the condition is called hyperhidrosis. Some medications are to blame, along with addiction to alcohol which can come with with night sweats as a side effect. Night sweats usually are more common with binge drinking or excessive use of alcohol. A single drink can actually make a person sweat. The same thing may happen when a person stops drinking and goes into withdrawal.

Body Heat and Alcohol

Drinking alcohol raises the body temperature. When the body gets warm, it perspires to sweat out the heat and cool the body down. Alcohol makes a person’s skin feel more warm but does not provide warmth against the cold. Just a little bit of alcohol causes blood vessels to dilate, moving warm blood closer to the surface of the skin, resulting in feeling more warm temporarily. The same veins are pumping blood closer to the skin’s surface, causing core body heat to be released.

Night Sweats and Withdrawal

Sweating excessively at night may be a sign of alcohol withdrawal, especially for people who have not had a drink for a day or so. Almost all people in acute withdrawal have decreased blood volume as a result of diaphoresis (profuse sweating), hyperthermia, vomiting, or abnormally rapid breathing. Acute withdrawal may find a person experiencing autonomic nervous system hyperactivity and an increased risk of serious symptoms like delirium tremens (DTs) and seizures. Seizures and tremors usually occur within the first 48 hours following discontinued consumption and peak around 24 hours.

Sweating Out Toxins

The primary function of sweating is to regulate the body’s internal temperature. When internal temperatures are reached, the body perspires to cool things down. As sweat evaporates, the surface of the skin is cooled. Sweat consists of 99% water and tiny residues of carbs, salts, protein, and urea. When a person does not consume water, this may impair the body’s detox and cause toxic retention.


By continuing to drink, a person may experience serious consequences. The best way to seek help is professional treatment for addiction. The following suggestions may also help:

  • Replenish lost fluids with water
  • Rinse skin to remove excess salt from sweating
  • Keep bedroom at a comfortable temperature
  • Avoid using heavy blankets
  • Change bed sheets before turning in for night

It may be hard for some people to avoid experiencing night sweats after they have been drinking. It all depends on the individual. The best way to get support is in a rehab environment that provides support for withdrawal and oversees the individual’s experience and can help them navigate it more effectively.
