The benefits of having a water cooler are not restrained to the summertime; it can also be beneficial to you to have a water cooler in the winter, as you do need to drink water all year round not only when it is hot outside.
A point-of-use or mains water cooler is a water cooler that is plumbed into your main water system, and when fitted with a good filter it can provide you with fresh, chilled drinking water whenever you feel like it.
Your body needs water throughout the year in order to maintain the around 70% balance that ensures that your body can work optimally. Your body loses water all the time via urination, exhalation, perspiration and various other natural bodily functions, which is why you need to constantly drink water in order to replace that which has been lost.
When you do not drink sufficient water you will become dehydrated and this will cause various things to happen in and to your body; your mouth will get dry, you will get thirsty, you will develop a headache, and your reactions and cognitive thinking skills will be slowed down. This can happen at any time, not just if you are doing strenuous exercise or during hot weather.
The great thing about having a water cooler in the winter is that, if you have invested in one of the more upmarket models such as the Living-Water Executive Water Cooler, you will have access to cold, ambient and hot water. So, even if you it is cold outside and you do not feel like drinking a cold drink, you will have immediate access to ambient water for a quick glass of hot lemon as well as to hot water which you can use to make your tea, coffee or hot chocolate without having to wait for the kettle to boil.
