5. Eat less salt
When you consume sodium (salt), water retention in the body is increased. This means that your tissue holds more water, including your breast tissue. Water retention can cause aches and pains, especially in areas with a lot of nerves. Your breasts will swell and feel tender and sore. So, if you’re coming up to your period, it makes sense to reduce the amount of salt you eat. You should consider the two weeks after your period to be the time when you can eat salt regularly without worry and the two weeks before your period the time you should cut back.
