Many times an athlete restricts his or her intake of water for a number of reasons. Whether they feel water will make them vomit or slow them down during physical activity or they just don't have enough water available to them at the time, an athlete should never restrict their intake of water. Very rarely does an athlete vomit from drinking too much water. Many products and sport drinks are available to help quickly replenish fluids during exercise or competition, but, contain artificial ingredients and chemicals. Read the labels of everything you eat or drink and don't assume it's the right thing to put into your body because some commercial on TV says so.
Water is the best choice for athletes or anyone who is physically active.
Always have plenty of water available during physical activity. Always drink water at room temperature during physical activity. Drink MORE than enough to quench your thirst. Drink even when you are not thirsty during physical activity. People who sweat more, should drink more.
