Here's What Actually Causes Moodiness During Your Period

The next time you’re feeling moody for no reason, it’s probably safe to say you can blame it on PMS (also known as premenstrual syndrome).

Roughly 50% to 80% of women have experienced some degree of physical or psychological PMS symptoms in her life.

Although PMS is not a new concept, YouTube channel AsapSCIENCE collaborated with YouTube comedian IISuperwomanII to take a closer look at the science behind why women get emotional before or during their periods.

The video also makes an excellent point that without the menstruation cycle, humanity would not exist. So a big round of applause to women who put up with PMS symptoms and periods!
