Water cooler bottles are used for keeping the water inside the bottle cool. Normal water bottles generally have only one layer. They are made of plastic, glass, stainless steel, etc. But when you are outside your home working, or working out in a gym, or doing other physical activities, you need cool water to quench your thirst. Normal water bottles are not good enough in those times. The reason for this is that the water gets warm in those bottles due to the conduction of heat from outside the bottle, as these bottles do not have proper heat insulation. So, the best solution for this is to use water cooler bottles.
Water cooler bottles use the heat insulation properties of their materials and trapped air to give the best cooling effect. These bottles have two walls placed side by side and which are separated by a vacuum. As the outside heat reaches the bottle’s outer wall, it will try to radiate heat through the vacuum between the two walls towards the inner wall. But because of the bottle’s heat insulation properties, the outside heat’s radiation and transmission processes do not fully take effect, and eventually, most of the heat will be lost. So, for several hours, the water inside will remain insulated from the outside heat and will remain pleasantly cool for you to drink. Just remember to tighten the cap properly after every use. For best cooling results also, you can put the bottle in the refrigerator for some time first before going out.
Buy a good plastic water cooler bottle to keep you refreshed during hot summer days or when working out or going cycling. When buying, look for a wider mouth in the bottles that would allow you to put ice cubes in or to stir the drink inside. Also, make sure that the walls are flexible enough so that you squeeze the bottle without breaking it. Conversely, do not try to buy very cheap water cooler bottles. Cheap water bottles are made of plastics with high levels of Bisphenol A. This compound can cause infertility, pregnancy problems and other neurological symptoms. So, try to buy a decent water cooler bottle to keep health hazards away. Some water cooler bottles are made of stainless steel also but those are too inconvenient to carry because those are generally quite heavy.
Now, the next time you go outside for work or for gym, running or cross training, make sure you have a water cooler bottle with you. Drinking cool water will keep you fresh and cool all day long.
