Whether it’s swimming, hiking, sailing, cycling or some other active sport, you’ll probably be out in the sun far more often than you were during the winter months. And because the temperatures where you’re doing your activities are going to be above 70 and likely humid, you’re going to sweat.
That means that keeping hydrated is very important. Heat stroke is a potential killer, and while you’d have to be unlucky to suffer from it, it can sneak up on you. A hot day, a lot of sweat, little-to-no water consumption, and suddenly, you’re beginning to overheat. That can lead to headaches, hallucinations and such potential disasters as body organs shutting down in the most severe cases.
Keep in mind that you may not experience severe thirst as a sign your body is overheating. Some of the signs of dehydration can include loss of appetite, flushed skin, light-headedness, fatigue, and heat intolerance. Any or all of these symptoms are often subtle and can be attributed to other factors. But exhibiting these signs after a workout can spell potential trouble.
How do you know if you’re properly hydrated? Pay attention to urine color. Clear urine means you are optimally hydrated. Darker urine means it’s time to power up with more water and other quenchers.
For every pound of sweat, you will need to replenish your body with about a pint of water. It’s not uncommon for athletes, even weekend warriors, to lose five pounds or more during a vigorous workout. Don’t rely totally on sweat, either – if you’re not sweating, that can be mean you’re already badly dehydrated.
