The importance of hydration on a boat


You have probably heard this before as it is the mantra of any sportsman, regardless of one’s level:"You have to drink before you're thirsty and eat before you're hungry"! Think you’re safe from dehydration when doing water sports?Think again: wind, salt water, and exertion make you lose a lot of water. So don’t wait to have that drink (of water), your body will thank you, and I’ll tell you why.

Keeping hydrated when sailing

What exactly is dehydration?

The human body is 60% water. Dehydration occurs when an increase in water loss - urine, sweating, etc. - is no longer offset by a sufficient intake of water.Every day, our body eliminates 2 to 3 litres of water, which is naturally offset by our diet and drinking water.During physical exertion sweating is accentuated, causing us to lose up to several litres of water per hour. Hydrating yourself regularly becomes vital!


The symptoms of dehydration.

Even before feeling thirsty, the initial symptoms of poor hydration appear and they are numerous. First, a decrease in the amount of urine, the colour of which becomes darker. Then comes the sensation of thirst, which is already synonymous with a weight loss in water of about 1%. Subsequently, the lack of water can cause several uncomfortable sensations for an athlete: Lack of energy, feeling tired, decreased physical performance, headaches, and dizziness when standing up.


Hydration on a boat

Hydration and sailing.

Sailors fear two things: Dehydration and exhaustion from the heat. At sea, physical effort, along with the sun’s exposure accentuated by the effect of its reflection off the boat and sails, as well as the wind accelerating the loss of water, all lead to the phenomenon of dehydration. Here are a few tips to stay hydrated and in great shape!


Our advice:

1- Hydrate before, during, and after exercise

2- Drink the equivalent of one glass every 20 minutes

3- Drink flat water or check that the sodium content of your sparkling water is not too high

4- Children and older people are more sensitive, so make sure they stay hydrated as well


In short, during a boat trip make sure you have enough water for the trip's entire duration. Better to have too much than not enough!
