What’s the secret of a perfect day ?

Drinking a glass of water in the morning? A very good reflex!
Drinking a big glass of water upon waking provides a feeling of freshness and well-being. Moreover, it awakens the digestive functions since it’s the first liquid to arrive in the stomach!
Furthermore, the body which is composed on average of 60% water, needs around 1.5 liters of water daily (which is 8 glasses per day : one glass = 200 ml) (3).
Better to start drinking water in the morning because you may be too busy to think about drinking enough later on.
In conclusion, a good start in the day is important!
