Should You Drink Electrolytes Before or After a Dive?

If you're adding electrolytes to your dive routine, one question comes up all the time:

"Should I drink them before I dive or after?"

The answer is... both can make sense, depending on your dive day.

Before Your Dive

The goal isn't to chug a drink right before splashing in.

Good hydration starts well before you arrive at the dive site. By the time you feel thirsty, you're often already behind.

For morning dives:

Hydrate the evening before.
Drink fluids with breakfast.
Consider adding an electrolyte drink before heading to the boat, especially on hot days or when making multiple dives.

Between Dives

Surface intervals are a great opportunity to replace fluids you've already lost.

A bottle of water and an electrolyte drink can be an easy way to stay ahead of dehydration during a full day on the water.

After Diving

Your hydration needs don't stop when you climb the ladder.

Continuing to replace fluids after your last dive supports recovery after a long day in the sun, carrying gear, and breathing dry compressed air.

Don't Overdo It

More isn't always better.

Drinking excessive amounts of plain water in a short period can dilute your body's sodium levels. The goal is steady hydration throughout the day, not trying to "catch up" all at once.

A Simple Dive-Day Routine

Here's an easy strategy:

✔ Night Before
Drink water consistently throughout the evening.

✔ Morning
Hydrate with breakfast.

✔ Between Dives
Continue drinking fluids and eat a light snack.

✔ After Diving
Keep hydrating during the drive home and throughout the evening.

Hydration isn't complicated—it just needs to be consistent.
