Hydration in the Winter
January 30, 2017
Winter is a time when we may forget about the importance of keeping hydrated. But dehydration can happen just as easily in winter as in the heat of the summer. In the cold weather blood vessels constrict to conserve heat and maintain body temperature, in turn increasing blood pressure. To lower the pressure, kidneys make more urine, so there is less blood to fill arteries and veins, more trips to the bathroom and a greater risk of dehydration.
Not drinking enough water may also make it harder to keep off those extra winter kilos, when shorter days can mean less exercise and more eating! When hydrated, the body is better able to break down fat for energy and regulate the appetite. (We often think we are hungry, when in fact we are really just thirsty.)
Keep track of the colour of urine. Whilst being thirsty is an indication that the body is already getting dehydrated, if urine isn’t clear or light-coloured - more liquid, and ideally water is needed.
For the past few years, the seasonality of water has diminished. “Hydration with water, and in particular water from coolers, throughout the year is now the norm. There is no longer the mid-winter dip in sales. Consumers are understanding the need for year-round healthy hydration. Water delivers that. It is tooth-kind and calorie-free, so it helps in the fight against obesity and is especially useful in tackling childhood obesity. Water appeals to the trend towards wellness,” says WE Chairman, Derek Callaghan.
