The Hidden Causes of Night Sweats: What's Really Making You Sweat?

Published: Jan 08, 2024

Night sweats can be more than just an annoyance - they might be a sign of an underlying health issue. Let's dive into the surprising causes behind those drenching nighttime episodes.

Infections: The Sneaky Sweat-Inducers

Believe it or not, various infections can cause night sweats. Tuberculosis is a classic culprit, with nearly half of TB patients experiencing night sweats. HIV infection can also lead to night sweats, either during initial infection or as the disease progresses. Even less severe infections like endocarditis (heart valve infection) can trigger sweating episodes.

Hormonal Havoc

Hormonal changes are another common cause of night sweats. Menopause is the most well-known hormonal trigger, but it's not the only one. Conditions affecting the thyroid gland, like hyperthyroidism, can lead to excessive sweating. In men, low testosterone levels can sometimes cause night sweats.

Night sweats are episodes of excessive sweating during sleep, often indicative of underlying health issues such as infections or hormonal imbalances.

Medications and Substances

Your medicine cabinet might be the source of your sweaty nights. Antidepressants, particularly SSRIs and tricyclics, are notorious for causing night sweats in up to 22% of users. Other medications like diabetes drugs and hormone therapies can also be culprits. Don't forget about alcohol and caffeine - both can increase sweating in some people.
