Imagine not drinking anything at work all day. Neither coffee, nor water, nor a carbonated beverage. After 8 hours of work, you would be dying of thirst. This means that you should immediately meet your water needs after a night’s sleep. For this reason, drink 2 glasses of cold water as soon as you get out of bed in the morning from now on. German scientists determined that the metabolism worked 24% faster for the 90 minutes after doing this. Smaller amounts of water have no effect. In addition, another recent study showed that muscle cells develop faster when they combine with water.
A basic rule of thumb: Drink at least 2.5 liters of water a day!
