Why Hydration Is So Important in Water Polo

  • Marko Radanovic

Learn why hydration is extremely important in water polo, how dehydration affects performance, and simple ways athletes can stay hydrated before, during, and after practice and games.

Signs That You Are Dehydrated

Some common signs are:

  • Feeling thirsty

  • Dry mouth

  • Headaches

  • Heavy legs

  • Muscle cramps

  • Feeling dizzy

  • Low energy

  • Trouble focusing

  • Dark yellow urine

Again, one important thing:

If you already feel thirsty, you are already a little dehydrated.

That is why good athletes try to drink water consistently during the day instead of waiting until they feel thirsty.

A lot of water polo players think:

“I’m in the water all the time, so I can’t get dehydrated.”

But that is actually wrong.

Water polo players get dehydrated very often, especially during:

  • Hard practices

  • Long tournaments

  • Outdoor games in the sun

  • Swim sets

  • Summer training

The problem is that because you are already in the water, you usually do not notice how much your body is sweating.

And one very important thing to understand is:

When you already feel thirsty, your body is already a little dehydrated.

That means dehydration starts before most athletes even realize it.

At Waterpolo University, we always say that performance is not only about:

  • Shooting

  • Passing

  • Eggbeater

  • Swimming

Your body also needs:

  • Sleep

  • Recovery

  • Nutrition

  • Hydration

If your body is not working properly, your skills will not work properly either.

What Happens When You Are Dehydrated?

Your body needs water to function properly.

When you lose too much water:

  • Your muscles get tired faster

  • Your brain reacts slower

  • Your body feels heavier

  • Your energy drops

  • Your focus becomes worse

In water polo, dehydration can make you feel:

  • Heavy in the legs

  • Slow in swimming

  • Weak while shooting

  • Tired very quickly

  • Less focused during games

Sometimes players think:
“I’m just having a bad practice today.”

But many times, they are simply dehydrated.

Why Water Polo Players Get Dehydrated So Easily

1. You Don’t Feel Sweat in the Water

In basketball or soccer, athletes can clearly feel sweat.

In water polo, you are already wet, so it is harder to notice.

But your body is still sweating a lot during:

  • Swimming

  • Eggbeater

  • Wrestling at center

  • Counterattacks

  • Conditioning sets

That is why many players drink much less water than they actually need.

2. Outdoor Practices Make It Worse

A lot of water polo is played outside in the sun.

Heat + hard training + sun = much faster dehydration.

During tournaments, players can play multiple games in one day while sitting in the sun between games.

That makes hydration even more important.

3. Hard Practices Use A Lot of Energy

Water polo is one of the hardest sports physically.

Your body is constantly working:

  • Legs never stop moving

  • Swimming is nonstop

  • Wrestling is physical

  • Your brain is always thinking

All of this makes your body lose water faster.

How Hydration Affects Your Water Polo Performance

Legs and Eggbeater

Water polo starts from the legs.

When dehydrated:

  • Legs burn faster

  • Eggbeater feels harder

  • You sink lower in the water

  • You lose explosiveness

This affects:

  • Defense

  • Shooting

  • Passing

  • Body position

Everything becomes harder.

Shooting

Dehydration can affect:

  • Shot power

  • Accuracy

  • Arm speed

  • Coordination

Sometimes your shot feels weak or off during practice.

Hydration can actually be part of the reason.

Focus and Decision-Making

Water polo is a fast-thinking sport.

You constantly need to decide:

  • Pass or shoot?

  • Press or drop?

  • Drive or stay?

  • Help or recover?

When dehydrated, your brain reacts slower.

That can lead to:

  • Bad passes

  • Late reactions

  • Defensive mistakes

  • Poor decisions

Recovery

Hydration is also important after practice.

It helps:

  • Muscles recover

  • Energy come back faster

  • Reduce soreness

  • Prepare your body for the next practice

Players who stay hydrated usually recover much better during the season.

Simple Hydration Tips for Water Polo Players

1. Drink Water Before Practice

Do not wait until practice starts.

Start drinking water during the day before practice.

You want to arrive already hydrated.

2. Drink During Practice

Even small water breaks help a lot.

Do not ignore hydration just because you are in the pool.

3. Drink After Practice Too

Your body needs to replace the water it lost.

Hydration after practice is very important for recovery.

4. Use Electrolytes During Long Days

During:

  • Tournaments

  • Double practices

  • Hot outdoor days

electrolytes can help your body recover better.

5. Make Hydration a Habit

The best athletes do not hydrate only when they remember.

They make it part of their daily routine.

Just like:

  • Warming up

  • Stretching

  • Practicing fundamentals

hydration should become part of your discipline.

Final Thoughts

Hydration is one of the easiest ways to improve your water polo performance.

Even small dehydration can affect:

  • Energy

  • Legs

  • Shooting

  • Focus

  • Recovery

And remember:

If you already feel thirsty, your body is already starting to get dehydrated.

That is why smart athletes drink water consistently throughout the day and not only during practice.

At the end of the day, your body is your engine.

If the engine is not working properly, performance will drop no matter how talented you are.

Take hydration seriously, especially during:

  • Summer

  • Tournaments

  • Outdoor practices

  • Hard training weeks

Because small habits create big results over time.
