# Summer Heat Hydration: What Our Athletes Get Wrong
When June rolls around in Bernardsville and the humidity creeps up, we start seeing a predictable pattern in our clinic. Athletes—from high school soccer players to weekend warriors—show up with headaches, muscle cramps, and complaints of "just not feeling right" during practice.
Nearly every time, the conversation circles back to the same question: "Am I drinking enough water?"
The honest answer? It's usually not about how much they're drinking. It's about when, what, and how often.
After years of working with local athletes training in New Jersey's sticky summer conditions, our team has learned that hydration mistakes cost performance. And worse, they can lead to heat-related injuries that sideline athletes for weeks. Let's walk through what we're seeing—and what actually works.
The "Drink a Ton of Water" Myth Doesn't Work in Heat
Here's what happens: An athlete shows up to 7 a.m. practice, chugs a 32 oz bottle before warmups, and thinks they're set for 90 minutes. By the third quarter, they're cramping, dizzy, or worse.
The problem isn't the water itself—it's the timing and the sodium.
When you drink a large volume of plain water on an empty stomach, it dilutes your blood sodium levels (a condition called hyponatremia). Your body actually loses electrolytes through sweat, so you need to replace them, not dilute them. This is especially true in the humidity we deal with here in northern New Jersey, where sweat doesn't evaporate efficiently. You're sweating more, losing more minerals, and plain water alone can't compensate.
What we recommend to athletes who train here: Start hydrating the night before. Drink consistently throughout the day—not a huge dose at once. And during practice or competition lasting more than an hour, you need electrolytes, not just water.
Timing Beats Volume—Every Time
We've worked with everything from competitive lacrosse teams to adults training for half-marathons, and the athletes who perform best in summer heat aren't the ones guzzling the most water. They're the ones hydrating strategically.
Our approach, which we share with every athlete we see:
Two hours before exercise: Drink about 16-20 oz of fluid (water or a drink with electrolytes). This gives your body time to absorb it and regulate fluid levels.
Every 15-20 minutes during exercise: Take smaller sips—4-8 oz at a time. This prevents your stomach from being sloshed and allows steady absorption.
After exercise: Drink about 16-24 oz for every pound of body weight lost during the workout. (Yes, you can weigh yourself before and after to know this.)
This approach works for summer camp pickup games, early-morning training sessions at Bernardsville High School, or weekend tournaments at local sports complexes. The athletes who adopt this rhythm—rather than the "drink as much as possible" approach—report fewer cramps, better focus, and quicker recovery.
What You're Actually Losing (Hint: It's Not Just Water)
Your sweat contains sodium, potassium, magnesium, and calcium. In our humid New Jersey summers, you can lose significant amounts in 60-90 minutes of training.
If you're only replacing water, you're creating an electrolyte deficit that shows up as:
- Muscle cramps (especially in the calves and quads)
- Dizziness or lightheadedness
- Difficulty concentrating
- Delayed recovery (soreness that lasts longer than it should)
For training sessions under an hour, plain water is usually fine if you've eaten a balanced meal beforehand. But for anything longer—or for outdoor summer training in heat—sports drinks with sodium (300-600 mg per liter) or electrolyte tablets mixed into water make a measurable difference.
We've seen athletes who switched to electrolyte-inclusive hydration protocols report better muscle recovery and fewer mid-season injuries. It's not just about feeling better during practice; it's about reducing the strain on your joints and soft tissues.
Your Hydration Plan Starts Before Summer
One thing we emphasize with everyone who comes through our door: hydration is a habit, not a game-day decision.
If you wait until June when the heat hits to figure out your hydration strategy, you'll spend July recovering from preventable issues. Instead, we recommend building the habit now—before peak summer temperatures.
Start tracking how much you drink throughout the day. Notice when you feel thirsty (hint: you should never wait until you're thirsty if you're exercising). Experiment with different electrolyte drinks or tablets to find what your stomach tolerates. And if you're training multiple days a week, keep a hydration log so you can see patterns in how your body responds.
The athletes we see who do this simple prep work show up in July and August not just ready to train, but actually thriving in the heat.
