Waking Up Sweating

When a person wakes up drenched in sweat, even if the room temperature is cool, then that person might be suffering from a medical condition that is known as sleep hyperhidrosis. This can occur in a localized manner (no underlying pathological condition) or generalized (often a symptom of other medical conditions). It affects persons of any age but most commonly appears in adults. Women are more affected by this condition than men, especially those who are going through menopause. Also, dark skinned individuals present a higher risk for sleep hyperhidrosis than those with a fair skin.

There are certain factors that increase the risk for a person to wake up sweating. These are, among others: obesity, drinking excessive quantities of caffeine-based drinks, alcohol and eating unhealthy foods. Also, it is important to understand that the excessive sweating during the night might represent a sign that there is an infection somewhere in the body. It is for the best to consult a doctor and identify the exact cause that leads to you waking up drenched in sweat. The doctor will recommend the necessary tests and investigations for the confirmation of the diagnosis.
