Dehydration During Winter 6th August 2020

Dehydration during winter is actually more common than you may think. In fact, there are articles out there which claim that dehydration increases during winter even though we’re less thirsty1. In this blog, we’ll look into why dehydration occurs during winter. 

Why does Dehydration Occur During Winter

Usually when we sweat, we are losing body fluids and know that we’re getting dehydrated. But what about if we don’t sweat, or if we don’t realise that we’ve been sweating?

During winter, sweat tends to evaporate rapidly due to the dry and cold air2. We also wear layers of clothing, or even just heavy clothes, which makes the body work harder and results in greater sweat levels.

Ever notice during cold mornings that you can see your breath as you breathe out? That is water vapour which is being lost from your body2.

You can also easily get dehydrated while exercising during winter. This is because the cooler temperatures means that your body doesn’t acknowledge that you’re thirsty2. You will end up drinking less fluids.

Winter is the peak time for the flu and colds, especially during August3. When this sickness occurs, you may experience fever and sweating resulting in a loss of body fluids.

Symptoms

Here are some of the dehydration symptoms to look out for during winter2:

  • Dark coloured urine
  • Fatigue
  • Dizziness
  • Lack of sweat
  • Dry and sticky mouth
  • Being extremely thirsty

How to Stay Hydrated

The best way to avoid dehydration is by not waiting until you feel thirsty, as you are already well dehydrated by this stage. It’s important to drink fluids throughout the day to keep yourself hydrated. Water is an easy solution but does not help replenish lost electrolytes. Some sports drinks have high sugar levels and contain less electrolytes than other options. The best solution to treat and prevent dehydration is an Oral Rehydration Solution (ORS), which contains both glucose and electrolytes. They can also replenish essential body fluids and salt lost through dehydration.

BIOLyte is an ORS with Prebiotic and Zinc. Not only does it aid in fast rehydration, but it can also help reduce both diarrhoea and vomiting. The Prebiotic helps with the growth of friendly bacteria in the gut while the Zinc helps to reduce stool output and frequency. BIOLyte also meets the World Health Organization guidelines for ORS formulation.
