Hydration in Winter

Hydration in Winter

It’s officially December, and you might be thinking hydration isn’t as important now. After all, cold weather means we’re not sweating as much, right? But what if we told you hydration is just as important in the colder months - and far more necessary than you might think? In fact, it can be even more important, as we’re often less aware of dehydration in the cold. We spoke to our co-founder and neuroscientist, Dr Paul, to get the lowdown.

Heating your home during winter can leave you dehydrated without realising it. While you may not be sweating as much as in summer, indoor heating dries out the air. Cold, dry environments also increase water loss - the condensation you see when you breathe on a crisp morning is water leaving your body. Staying topped up with water and electrolytes is vital to keep your body replenished. In colder temperatures, your sense of thirst is diminished by up to 40%, even when you are dehydrated, as highlighted by Dr Ashwin Sharma in The Independent.

Hydration doesn’t just prevent dehydration - it’s also your first line of defence against illness. When your body is well hydrated, it supports healthy mucous membranes by keeping the lining of the mouth, nose, throat and lungs moist. These membranes act as a barrier against airborne infections such as the flu virus. When we’re dehydrated, this protective barrier becomes less effective, allowing harmful pathogens to enter the body.

As discussed in our blog introducing Daily Immune+, this formula is designed not only to support hydration and mucus function, but also to give your immune system additional support during the colder months. With just one daily tablet, your body receives added vitamins C and D, iron, zinc and selenium to help keep your defences strong.

Hydration goes even further. It impacts everything from muscle function to brain health. Poor hydration can affect concentration, mood and reaction times - effects that may be amplified during the darker winter months when mood is already lower. Staying hydrated helps support mental clarity and focus, alongside immune defence.

The main takeaway? Hydration isn’t seasonal. While the weather changes, your body’s need for water, vitamins and minerals does not. Prioritising hydration throughout winter supports immunity, wellbeing and overall health.
