1. Crash Dieting
Each time you gain and lose weight, breast tissue becomes more slack, kind of like old tights.
It's not only dangerous for your lungs but also for your breasts. It slows down your blood flow and makes your skin saggy.
3. Wearing an unsupportive bra
Your breasts may sag because they don't have enough support.
4. Not consuming enough water
We all know that there are many benefits of drinking water but what about not drinking enough water? If you don't drink enough water then your skin eases off and your breasts become saggy.
