Drink More Water
Interestingly, being well-hydrated can actually reduce water retention (27).
Your body is always trying to achieve a healthy balance, so if you are constantly dehydrated your body tends to retain more water in an attempt to prevent water levels from becoming too low.
Achieving an optimal daily water intake can also be important for liver and kidney health, which may reduce water retention in the long-term (28, 29).
The benefits of drinking more water don't stop there. Other research shows that it's also important for health, fat loss, brain function and more (30, 31, 32, 33, 34).
As always, achieving a balance is optimal. If you drink excessive amounts of fluid you may actually increase your water weight.
Simply drink when you're thirsty and stop when you feel well-hydrated. You should also drink slightly more in hot environments or when exercising.
You can also monitor your urine color to assess hydration. It should be light yellow or fairly clear, which is a good indicator that you are well-hydrated.
BOTTOM LINE:
Dehydration or over-hydration can lead to water retention. Make sure to drink balanced amounts of water each day.
