What Are Night Sweats: Get the Facts

What are night sweats?

Night sweats are also called as nocturnal hyperhidrosis, which means excessive sweating during the night. Night sweats are episodes of continuous sweating at night even when the environmental temperature is very cold. Some people may sweat so extensively that they might find their bed sheets drenched in the morning. Although night sweats are so annoying, they are usually harmless.

If you only experience them once in a while, then there is nothing for you to worry about because such presentations do not indicate a serious medical condition. However, if you have been repeatedly experiencing night sweats, then it could be a sign of an underlying medical condition. If this is the case, then you should visit a healthcare professional.

However, there are other diseases such as the HIV infection, abscesses, and osteomyelitis that may give rise to night sweats as well.
  • Cancer - Night sweats can be an early symptom of certain cancers such as lymphomas and leukemias. However, this is not a common presenting symptom and cancer would manifest with other symptoms as well, such as sudden and unexpected weight loss and loss of appetite.

When should you seek treatment?

Night sweats are usually harmless and not a usual cause for concern. However, sometimes, having night sweats can be an indicator that you have an underlying medical condition. Therefore, if you are frequently having night sweats that disturb your sleep or when night sweats are associated with other signs and symptoms, then it is time for you to visit a healthcare professional.

If you have night sweats associated with the signs and symptoms such as loss of weight and appetite, fever, or a cough, then it may be a sign of a serious medical condition. Additionally, if you have already been diagnosed with lymphoma or AIDS, then it may be a sign that your condition is progressing. Visit your health care professional in such situations as well.
