August is typically the hottest month of the year. Whether at work or at home, ensure you are drinking at least half your body weight in ounces per day to stay hydrated. You will need to drink more if strenuous activity like construction work, sports, yard work is in your plans.
REMEMBER: If you are thirsty, you are already dehydrated.
Hydration starts before you exert yourself. Begin hydrating two hours before your activity and every 15 minutes during the activity. During competition and after, you need to replenish fluid and electrolytes lost from sweating. A person who is 4 percent dehydrated has a loss of 20 percent from their performance.
Plain water is best for activities which require an hour of continuous exertion or less. For activities which require more than a continuous hour of exertion, consider sports drinks.
The large amounts of caffeine in these drinks can work more like a diuretic, which can lead to dehydration. Energy drinks with large amounts of sugar also slow down digestion and fluid absorption. Users may experience upset stomach, increased heart rate and jitters.
