2. Blunted Thirst and Sweat Awareness
In cold weather, you may not feel as thirsty as usual when exercising. This is because the blood vessels constrict to focus blood flow to the core parts of the body (leaving our fingers and toes to feel the cold!). This fools the brain into thinking its important parts are getting the fluids they need, but overall they aren't!
Cold-weather exercise also distracts us from realising quite how much we're sweating. Not only do we not notice our thirst, but cold air can also confuse the cooling effect of sweating, so we may not recognise the need to rehydrate as we work.
3. Reduced Daylight and Micronutrient Status
Winter brings shorter days and less exposure to sunlight. During these darker months, we get less natural vitamin D, which affects bone health, immunity, and muscle performance. While not related to the conventional fuelling pillars of carbohydrates and electrolytes, this vitamin D drop is worth highlighting.

Adapting to the Cold: How to Make Your Sports Nutrition Winter-Ready
Now that we've covered how cold weather affects your body's needs, let's shift to why it requires athletes to fuel differently as the weather cools. At OTE Sports, our fuelling expertise focuses on two key areas: carbohydrates and electrolytes.
Boosting Carbohydrates
The increased energy demands of training in the cold mean we rely on carbs more than ever during winter to both power our exercise and generate body heat, but how should you change your carbohydrate intake during autumn/winter training?
We recommend upping your carb intake to compensate for the body's higher demands. Generally, this should be a 10-20% increase to your normal consumption, as everyone will have different nutritional requirements.
Introducing Electrolytes
Not everyone trains with electrolyte drinks, and that's okay. During the winter, however, these drinks can be the ultimate countermeasure for profuse sweating during exercise in heavy clothes. Cold, dry air can also draw moisture from your breath, so it's vital to replenish fluids efficiently during these autumn/winter workouts.
Electrolytes are lost through sweat, and electrolytes like sodium and potassium help the body rehydrate and transport large volumes of blood to muscles. During the winter, adding high-electrolyte drinks to your hydration plan can help you replenish fluids faster and more effectively.
