Healthy drinking habits

Everyone knows that most of our body weight is water, but not all of us adopt good drinking habits. Here are key habits to keep in mind when it comes to smart drinking:

Other than the water you consume through fruits and vegetables, drink a minimum of 6 (women) / 8 (men) glasses of water every day (1 glass = 250 ml) . If you don't eat much fruits and vegetables, add 2 more glasses. On top of that, add 2 more glasses for every 30 min of intense exercise.
Drink a glass of water as soon as you wake up in the morning.
Optional: Track the number of glasses of water you drink every day (you can use an app). It will help you to form a habit and achieve the daily minimum.
You can drink coffee, but only till noontime, so that the caffeine will not affect your sleep quality at night.
Most healthy coffee is Filter Coffee, and I recommend to use an organic and medium roast brand and to ground it yourself just before making it.
You should drink green tea, but only till noon. After noon you can drink infusions tea with no Caffeine.
Other than tea and coffee, drink only water. Don't drink soft drinks, sodas or alcohol.
Our water is not "rich and safe" as it was in nature thousands of years ago, and every type has its own disadvantages. This is why I recommend to simply consume water from several sources if possible (Purified at home, a number of mineral brands, etc.).
Avoid drinking from plastic bottles. If you must do so, make sure they don't contain BPA (also apply to plastic you eat from).
Drink in small sips, instead of a large amount at once.
Avoid drinking very hot drinks.
