Author By: Tallene Hacatoryan, MS, RD, CLT on 27 Mar, 2018

If you are wearing too many layers or sleeping in a hot environment, this may cause sweating at night. However, the term night sweats, also known as hyperhidrosis, is used for severe hot flashes at night, unrelated to environment. This is not characterized by flushing, warmth and redness to the face, rather, night sweats are a bit more extreme in severity.

Night sweats are often repeated episodes related to a medical condition or illness and may be associated with fever, chills, weight loss, localized pain, cough, diarrhea or other symptoms that are concerning. It is important to consult a health-care professional for unexplained night sweats that do not resolve over time. Treatment of night sweats depends on the underlying cause of the problem, which is a major part of resolving the issue.

Night Sweats Cause #1: Caffeine

Although night sweats can be a symptom of a more serious health concern, in some instances, it may be related to diet and lifestyle. That hot cup of coffee that you start your day with may be keeping you up at night. Coffee and caffeinated beverages are considered triggers for excessive sweating at night.

Caffeine may exacerbate hormonal symptoms of menopause as well. Some studies suggest that caffeine may worsen hot flashes and night sweats in post-menopausal women. Since caffeine is a stimulant, your central nervous system may become triggered and increase your heart rate, raising your blood pressure and activating sweat glands.
