In the UK we have some of the cleanest tap water in the world, which means there are no health benefits of bottled water over tap water. And let’s face it, the manufacturers of bottled water fill up their bottles from… taps.
When it comes to the environment, tap water wins hands down. Not only does it take three litres of water to produce a one-litre bottle of water, but you also need to include the environmental cost of transporting that water from its source to the shop which adds to its carbon footprint, and of course, there’s the problem of disposing of the plastic bottle. So, if your company wants to raise its sustainability credentials, get rid of the water cooler that uses plastic bottles and encourage employees to drink tap water instead.
If your employees are concerned about the temperature of the water - and granted, on a warm day it is much nicer to drink cooled water - then encourage employees to fill up reusable water bottles and keep them in the fridge. It may take a bit more thought and planning, but it will be just as effective when it comes to temperature, better for the environment, and a lot cheaper for your company.
There’s no evidence that drinking water that’s at room temperature or drinking cold water makes any difference when it comes to quenching thirst and rehydrating your body. As long as you encourage your staff to stay hydrated, that’s enough. This means there’s no excuse when it comes to encouraging them to drink tap water instead of expensive bottled water.
However, drinking cold water really does make a difference when it comes to exercising, helping to keep your core body temperature lower for longer.
On the other hand, if you’re cold, drinking hot water will help you stop shivering and maintain your core temperature. Drinking hot water can have other health benefits. As it heats the body, it will expand the blood vessels which will help to improve circulation and help to relax your muscles. If you’re drinking more water to help fill you up before a meal and raise your metabolism, then research has shown that hot water is more effective, by as much as 40% over a 40-minute period.
It doesn’t matter what the temperature of the water is, it’s important that your employees stay hydrated - whether that’s through bottled or tap water, flavoured waters, tea, coffee or milk, or eating plenty of fruit and vegetables. Studies have shown that even being mildly dehydrated has an adverse effect on mood and brain function, and more severe dehydration will raise the heart rate.
