Hydration Tips for Athletes: Hydration in Hot Weather

As temperatures start to heat up, we have to talk about how athletes stay hydrated! Hydration is one of the simplest (and most powerful) ways to support your performance, energy, and recovery.

Why hydration matters more in warmer weather

When it’s hot, your body sweats more to cool down. That sweat loss isn’t just water, you are also losing electrolytes like sodium. If you are not replacing both fluids and electrolytes, you may start to feel more tired and notice headaches, dizziness, or muscle cramps.

Signs you may be dehydrated

  • Dark yellow urine
  • Low energy or sluggish workouts
  • Headaches
  • Dizziness or lightheadedness
  • Muscle cramps

Simple hydration strategies to stay on top of it

Start your day hydrated
Don’t wait until practice. Start sipping water when you wake up so you are not playing catch up later.

Sip consistently
Instead of chugging water right before practice, keep a water bottle nearby (in class, at home, on the go) and take small sips throughout the day. There is nothing worse than chugging water before practice and feeling sloshy with every step.

Add electrolytes when needed
For longer or more intense workouts lasting more than an hour or session in the heat, pack a sports drinks or pair your water with a salty snack before practice.

Remember: hydration is individual

Your needs depend on your sweat rate, sport, intensity, and environment. What works one day might not be enough the next, especially during longer practices or hotter conditions.
