Drinking water immediately after waking up is a popular ritual in Japan. The Japanese believe that drinking water first thing in the morning can help heal and manage epilepsy, bronchitis, asthma, diarrhea, vomiting, urine and kidney diseases, diabetes, menstrual disorders, meningitis, arthritis, headache, heart beating fast, eye diseases and help you manage a healthy weight.
Not many people like to drink water first thing in the morning. Instead, most people prefer tea or coffee but it is recommended to drink water or at least eat fruits that contain water.
While you sleep, your body is filtering out all the toxins you’ve accumulated throughout the day. The little bit of water that’s left in your digestive tract by the time you get to bed isn’t enough to clear away all this waste. Drinking water as soon as you wake up will give your kidneys more to work with to help them eliminate all the toxins that are clogging your system.
Why Drink More Water
Drinking water is important for mental clarity and alertness. In fact, dehydration is a risk factor for delirium and dementia in the elderly and in the very ill (1). It’s also important for nearly every bodily function. In fact, in as little as 3-4 days, dehydration can become deadly.
“I have sort of a 100-hour rule,” says Claude Piantadosi of Duke University in North Carolina. “Depending on the temperature you are exposed to, you can go 100 hours without drinking at an average temperature outdoors. If it’s cooler, you can go a little longer. If you are exposed to direct sunlight, it’s less,” he added. via NBSNews
“Dehydration kills by bringing blood pressure down to fatal levels. The more energy you expend the more likely you are to lose water,” says Randall Packer, an expert from George Washington University. “You lose a little bit of water every time you exhale. You lose water when you sweat. You do make a little water when you metabolize food… but the balance is such that you always need some sort of water intake.” (2).
