Dehydration is one of the most common and most preventable performance problems in hockey. Study after study has shown that even mild dehydration — a loss of just one to two percent of body weight in fluid — measurably impairs physical performance, reaction time, decision-making, and mood. For a hockey player, those are the exact capacities that determine success on the ice. And yet, chronic under-hydration is extremely common among competitive players, particularly teenagers who are not in the habit of thinking about their fluid intake.

The challenge with hockey-specific hydration is that the cold environment of a hockey rink masks the sensation of sweating. Players don't feel hot and sweaty the way they would after a summer run, so they don't perceive their fluid losses as significant. But skaters in full equipment can lose one to two liters of sweat per hour during high-intensity play. Over a sixty-minute game with warm-ups, that represents a substantial fluid deficit that has to be replaced proactively rather than reactively.

The basic standard for hydration is to arrive at every practice and game already well-hydrated — meaning your urine is pale yellow or clear — and to drink consistently throughout the session rather than waiting until you feel thirsty. Thirst is a late signal. By the time you feel thirsty during exercise, you're already somewhat dehydrated. Build the habit of drinking before you need to, and your performance will reflect it.

What to Drink and When

Water is the foundation of hydration and should make up the majority of your fluid intake throughout the day. For sessions lasting longer than sixty minutes or games played in warm indoor environments, a sports drink that provides carbohydrates and electrolytes can be beneficial for maintaining energy and replacing sodium lost in sweat. Avoid relying on energy drinks as a hydration strategy — the caffeine content accelerates fluid loss and the sugar content in most energy drinks is not formulated for athletic performance. Drink water. Drink it consistently. Make it a habit before it becomes a problem.

At Hockey Horizons, we believe that what happens away from the rink is just as important as what happens on it. Nutrition is one of the most powerful and most overlooked performance tools available to junior hockey players.
