We always suggest that a client drinks plenty of water after receiving a massage. In fact, drink plenty of water even several days after the massage to keep your body hydrated. The general rule is drinking eight glasses of eight-ounce of water daily. However, the specific amount depends on your weight. So the exact amount of water you drink is up to you. Listen to your body, if after having some water you still feel thirsty, it might be a good idea to drink more water.
