Why does the neck sweat at night while sleeping in an adult?

Sweating is a natural process for the human body. Sweat removes harmful substances, helps in cooling the body. However, there are situations when excessive sweating causes inconvenience or even causes concern. Especially if it happens at night. For example, when the neck sweats during sleep.

Excessive neck sweating during night sleep: we understand the situation

If you have noticed this problem, you should understand it in more detail. Excessive sweating, or, in scientific terms, hyperhidrosis, is a fairly common phenomenon. There can be many explanations for the process of sweating in the neck that occurs during sleep, from the most banal to serious ones that require medical treatment. Let’s look at the most common ones first.

Wrong diet

Eating heavy and high-calorie foods or alcoholic beverages before going to bed will inevitably lead to feelings of heaviness in the stomach and profuse sweating. At night, the body of an adult must rest, and the digestion of food requires increased blood flow, which provokes the release of sweat.

It is desirable that the last meal was 2-3 hours before bedtime and consisted of easily digestible foods.

Heightened emotionality

If you are by nature an emotional person, impressionable, vulnerable, this fact can also be the cause of excessive sweating in a dream. The peculiarities of the functioning of the nervous system of such people leads to the fact that excessive excitement causes them to have a rapid heartbeat, which causes a rush of blood to the skin, especially in the head and neck. For such people, sound sleep is especially important, so they are shown walking in the air, refusing active activities in the evening, it is possible to take herbal teas with a calming effect.


Another very common reason that the neck, chest and back of the head sweat profusely at night can be overweight. As a rule, for obese people, sweating can be a frequent occurrence during the day, but at night it leads to regular awakenings, and, as a result, to lack of sleep, chronic fatigue. It would be good to take measures to reduce excess weight, since obesity, in addition to sleep disorders, can lead to a whole “bouquet” of more serious problems.

Taking medications

Some medicines can increase body temperature and increase sweating during sleep, including in the neck. This side effect should go away after you stop taking the drug.

High humidity and temperature

The simplest non-compliance with the temperature regime in the room can also lead to the neck and neck sweating profusely at night.

Doctors consider falling asleep at a temperature of ­16-19 degrees optimal. It’s pretty cool, but it is under such conditions that the body produces melatonin, the sleep hormone responsible for the coherence of our entire body and strong immunity.

Humidity in the room also has a big influence. Waterlogged air often also causes excessive sweating during a night’s sleep. Doctors recommend that you carefully choose the temperature and humidity that are comfortable for you in the room. Well, if you are a fan of heat, do not forget to at least ventilate the room well before going to bed.


An important point in deciding why the neck sweats at night is the observance of the rules of personal hygiene.

  1. Carrying out water procedures before going to bed cleanses the skin, removes impurities and sweating secretions.
  2. It is important to use bed linen and nightgowns made from natural materials that have the ability to absorb sweat, relieving discomfort, and not causing a “greenhouse effect”.
  3. Bedding should be washed regularly.

If these personal hygiene measures are observed, night sweats in an adult should not become a problem.
