Sweating at night is something many people experience, and it usually has a harmless cause, such as a bedroom that is too warm, thick bedding, or a demanding phase in life. Night sweats warrant further investigation when you repeatedly sweat so heavily that your clothing or bedding becomes soaked, even though the surroundings are not too warm. Because the causes are wide-ranging, a structured look at possible triggers can be helpful.
Possible causes
Environment and Lifestyle
A warm bedroom, bedding that is too thick, late heavy meals, or alcohol in the evening are common and easily remedied reasons for night sweating.
Hormonal Changes
Around menopause or with other hormonal changes, increased night sweating is common and usually easy to identify.
Infections and Metabolism
Feverish infections or an overactive thyroid can be accompanied by night sweats. Such causes can usually be checked easily.
Psychological Stress
Stress, inner tension, or restless nights can also lead to increased sweating during sleep.
Typical steps at the doctor's office
- 1Your doctor will ask how often and how severely the night sweats occur, what your sleep environment is like, and whether you have any other symptoms.
- 2A physical examination and, if necessary, blood tests help to narrow down common physical causes.
- 3Depending on the results, treatment of the identified cause follows, or adjustments to your sleep environment and daily routine may be sufficient.
What you can do yourself
- Ensure you have a cool, well-ventilated bedroom and breathable bedding and nightwear.
- Avoid late, heavy meals in the evening as well as alcohol, which can promote night sweating.
- Pay attention to ways of reducing evening stress and promoting restful sleep.
- Observe in which situations the night sweats occur, as this makes evaluation easier.
Seek medical advice if the night sweats occur repeatedly, you wake up heavily soaked even though the environment is not too warm, or if they persist over a longer period of time. Your general practitioner is the right point of contact to systematically narrow down the possible causes.
