Hydration reminder!

They are plenty of articles on hydration and most of us have read at least one. So I am not going to bore you with all the scientific facts but I just wanted to write a short reminder about hydration in winter.

As we all know, hydration is one of the most if not the most important thing to remember during exercise, let alone races. But a lot of people do not realise that it is as important in cold weather as it is in hot weather.

Wearing extra clothing. Heavy jackets, long underwear and other pieces of warm clothing help your body conserve heat. But the added weight is one factor that makes the body work between 10 and 40 percent harder.

By working harder, the body produces more sweat, contributing to fluid loss. In cold weather, we lose more fluids through respiratory water loss. For example, when you can see your own breath, that’s actually water vapor that your body is losing. The colder the temperature and the more intense the exercise, the more vapor you lose when you breathe. Sweat evaporates more quickly in cold air. We often think we are not sweating in cold, dry weather, because it tends to evaporate so quickly. Wrong! And unfortunately it can make you less thirsty.

Below is a simple and useful poster (reminds me of school)!


Winter is coming! it’s going to get cold BUT remember, stay hydrated! Drink well during and especially days prior races and long training runs/workouts and treat yourself, buy some new gear, you deserve it!

Keep smiling!

  1. Cheers for that. Also don’t neglect salts (electrolytes). In many ways as important, and as we tend to take them on board with water, you can do both by dropping a few tabs into your bottle. Most of us lash in the gels so we get the sugar hit we need, but often forget the salts.
