As Mouannes suggests, “This hormonal imbalance directly affects the hypothalamus, the part of the brain responsible for the regulation of the internal core temperature. Therefore, some women might experience night sweats, hot flashes, and excessive sweating right before they get their periods.”
Hot flashes might sound like something you only experience in menopause, but similar hormonal changes occur during your period. As progesterone levels increase, there’s often a slight increase in your body temperature, although most don’t notice it. As progesterone levels rise and oestrogen levels fall, the decrease often sees the brain release other hormones that make the brain more sensitive to small changes in body temperature. The result? Hot flashes that see your body sweat so you can cool off.
In a similar vein to bloating and headaches experienced by many before their period, excessive sweating and hot flashes are also common and as a result, typically they aren’t cause for concern. That said, persistent sweating outside of your period could be an indication of other pressing medical issues. For instance, fever, chill, abdominal pain, vaginal discharge, and weight change along with sweating could be something more serious, making an appointment with your healthcare professional a necessity.
