Hydration plays a bigger role in performance than most people realize.

The human body is made up of roughly 40–75% water. Muscle alone contains about 70–75% water, which means even small changes in hydration can impact how your body feels and performs.

At Breathe in Motion, we work with active individuals in Brookfield and Mequon to improve performance, recovery, and injury resilience—and hydration is a key piece of that.

Why Hydration Matters

Water supports nearly every system in the body.

It helps:

  • Regulate body temperature
  • Transport nutrients
  • Support cardiovascular function
  • Lubricate joints
  • Maintain muscle function
  • Aid digestion
  • Support brain and nervous system function

When hydration is off, performance and recovery are affected quickly.

What Happens When You’re Dehydrated

Dehydration occurs when fluid intake doesn’t match fluid loss.

This can happen with:

  • Exercise and sweating
  • Illness
  • Not drinking enough throughout the day

Even a small loss—around 2% of body weight—can begin to impact how your body functions.

Common Signs of Dehydration

  • Increased thirst
  • Dark-colored urine
  • Fatigue
  • Headaches
  • Dizziness
  • Muscle cramps
  • Dry mouth
  • Difficulty concentrating
  • Constipation

These symptoms often show up before people realize they’re dehydrated.

How Dehydration Affects Performance

Hydration directly impacts both physical and mental performance.

Physical Effects

  • Decreased strength
  • Reduced power output
  • Lower endurance
  • Increased fatigue

Cognitive Effects

  • Slower reaction time
  • Reduced coordination
  • Difficulty focusing

For athletes, this can affect both training and competition.

How Much Water Do You Need?

Hydration needs vary, but general guidelines can help.

Before Exercise

Drink 14–22 oz of fluid about 2 hours before activity.

During Exercise

Drink 6–12 oz every 15–20 minutes, especially during longer sessions or in heat.

After Exercise

Drink 16–24 oz for every pound lost during activity.

Water vs. Sports Drinks

For most workouts water is enough.

Sports drinks may be helpful when:

  • Exercise lasts longer than 60 minutes
  • You’re sweating heavily
  • You’re training in hot conditions

Why Hydration Matters for Injury Prevention

Dehydration doesn’t just affect performance—it can increase injury risk.

When hydration is low:

  • Muscles fatigue faster
  • Coordination decreases
  • Recovery slows

This can contribute to:

Simple Ways to Stay Hydrated

  • Keep a water bottle nearby
  • Drink consistently throughout the day—not just during workouts
  • Monitor urine color (light yellow is a good sign)
  • Increase intake during training or hot weather

The Goal: Consistent Hydration, Better Performance

Hydration isn’t about one big effort—it’s about consistency.

When your body is properly hydrated, you:

  • Perform better
  • Recover faster
  • Feel more energized
