After waking up, try to get at least 2 full glasses of water in order to active your internal organs. You may also be dehydrated from the night before so this can help to provide you with some liquids as well. Drinking a glass of water 30 minutes before a meal can be helpful for digestion as well. If you drink a glass of water before a shower and bed you can decrease your blood pressure and lower the risk of stroke and heart attacks as well. Timing is everything!
