Night sweats are episodes of excessive sweating during sleep that can soak clothing and bedding. They can occur for various reasons, including hormonal changes, infections, or certain medications. Night sweats are often associated with conditions like menopause, hyperhidrosis, or tuberculosis. While night sweats are usually not a cause for concern, they can disrupt sleep and lead to discomfort. If they occur frequently or are accompanied by other symptoms, it may be advisable to consult a healthcare professional for further evaluation and potential treatment options.
