Is it that time of the month? Drink an extra glass of water. Estrogen and progesterone influence your body’s hydration levels, and when the two are roller-coastering, like when you’re in the throes of PMS, you may need to increase your fluid intake to stay hydrated, Dr. Kominiarek says. What’s more, for some women who have excessively heavy periods, the amount of blood lost is enough to deplete fluid levels, says OB-GYN Marielena Guerra, MD, of Elite OB/GYN in Florida. If you think the latter might be you, start counting your tampons. If you have to change them more than once every two hours, talk to your gyno.
