What causes night sweats?

Night sweats are very common in women, particularly in women over 40. You do not have to be in menopause to start having these sweats, either.
Very often women begin to find that alcohol or caffeine use may trigger episodes of night sweats. Additionally, there are multiple medications that can cause day or nighttime sweats, especially antidepressants. A variety of medical issues such as low blood sugar, infection, and thyroid disease can also trigger these laundry-producing events.
