A current trend in Japan today is drinking water immediately after getting out of bed. Scientific tests have confirmed the medical value of this practice.
- When you wake up, before doing anything, drink two glasses of water, or 440 milliliters. If for any reason you cannot drink this much water at one time, you may start with as much water as you can drink, then gradually increase the amount.
- Then wait 40 minutes before eating or drinking anything or brushing your teeth.
I keep the gap between drinking water and eating my breakfast as long as possible, the 40 minutes is not always practical.
