Hydration Is the Skill Most People Haven't Mastered Yet

When Hydration Starts to Slip

Most people think hydration is simple. Drink water when you're thirsty and carry on. But athletes, coaches, and performance specialists tend to treat hydration differently. Thirst often appears after your body has already begun to adjust to lower fluid levels — which is one reason hydration is important, especially for anyone who is physically active.

Hydration works best when it stays slightly ahead of that signal — not as a reaction, but as a practice. Waiting until you feel thirsty can mean fluid loss has already begun to affect how you feel and perform.

Water helps maintain normal physical and cognitive function, which is why consistent intake matters for good health and hydration. Reaching your daily water intake is not always about following a fixed rule like eight glasses of water a day, but about understanding your body, your routine, and your level of activity. For some, drinking enough water also supports normal functions such as bowel movements.

But hydration is not only about water. Electrolytes matter too. Potassium contributes to normal muscle function and to the normal functioning of the nervous system. Magnesium contributes to electrolyte balance and to the reduction of tiredness and fatigue.

Together, fluids and electrolytes help maintain the balance your body relies on. When fluid intake drops too low in relation to sweat and activity level, it can lead to dehydration, affect body weight through temporary fluid reduction, and make it harder to stay hydrated over time.

The Two Parts of Hydration

Hydration works best when two elements stay aligned: fluid intake and electrolyte balance. Water provides the fluid. Electrolytes help regulate how that fluid moves through the body.

When both are present in the right balance, hydration works as it should — and the difference is most noticeable during long training runs, race days, and warm conditions. This is especially true when fluid loss increases and maintaining good hydration becomes harder through water alone.

Why May Changes the Equation

May is when training volume peaks for many runners preparing for summer races. Longer sessions, increasing temperatures, and higher sweat rates all place greater demand on fluid and mineral intake than cooler months require.

Whether you are counting down to a race or simply trying to keep pace with an increasingly active schedule, this is the month to build a hydration routine — not borrow one from winter. For anyone who is physically active, relying solely on thirst can make it more difficult to stay consistently hydrated.

SALTE was built around this idea. Clean electrolytes. Nothing extra.
