Summary

This study tested whether drinking a set amount of water each day (30-35 ml per kg of body weight) for one week could improve how older adults in nursing homes build muscle protein. Seventeen people aged 65 and older took part. The goal was to see if better hydration could help with muscle loss and strength.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
water
What this could lead to
If it works, this could point toward a simple, low-cost way to help older adults maintain muscle mass and strength.
What could go wrong
This is a very small, early trial with only 17 participants. Results may not apply to all older adults, and drinking more water may not be enough to prevent muscle loss.
