Below are some more potential causes for your sudden bout of cold sweats. So, if you start to experience cold sweats and you don’t know yourself to be a quick-to-sweat person, it could mean that something else is going on under the surface. “Understanding the cause of a ‘cold sweat’ depends on properly understanding the cause of the sweating and simultaneously understanding why there is a feeling of being cold,” he adds. Rather, it simply indicates simultaneous sweating and feeling cold. Having a “cold sweat” does not necessarily indicate any particular medical condition, says Dr. For this reason, cold sweats can be confusing and distressing for many patients, says Dr. Cold sweats can be caused by many things, some of which are not concerning and some of which are very concerning.

She explains that cold sweats can be defined as “a large amount of sweating that can be in response to decrease the body’s temperature, often followed with feeling chills.” What causes cold sweats? “Many people often say cold sweats, but what is often found in practice is many individuals are experiencing night sweats associated with chills,” says Tamika Henry, M.D., founder of Unlimited Health Institute.

When the cause of sweating is excessive internal or external heat, the body is sweating to cool off. Although there are many different causes, the result is sweating or in medical terminology, diaphoresis.” “Stressing the body to elicit a sweating response might occur from emotional, physical, or chemical stressors. The heat commonly may be generated from internal sources, such as muscle activity or infection, or it can also exist externally from environmental factors or excessive clothing, says David Cutler, M.D., family medicine physician at Providence Saint John’s Health Center in Santa Monica, CA. Sweating is the body’s natural response to heat or stress. Most people have experienced a cold sweat before, whether you’ve broken out in sweat during a fever, or your palms have gotten clammy when you’re nervous, or maybe you’ve woken up from a nightmare completely drenched.
