Stay hydrated While Swimming.
When you swim, believe it or not, you sweat. It is important, as with any sport, to drink plenty of water; before during and after your workout. Don’t make the mistake of thinking just because I am in the water I am getting plenty of fluids. The water washes away the feeling of sweat thus the old thought of “I’m not sweating”. There are a lot of different types of hydration drinks. Avoid caffeine whileas its dehydrating affects will inhibit your performance, cause headaches and the ability to think clearly.
When you sweat your body loses important electrolytes and inhibits your performance. Remember to always bring hydration in a non-breakable container onto the pool deck!
