Drinking water is good for your health．There are some scientific ways of drinking water．

1．It is the best medicine to drink two glasses of water in the morning．

2．Drink clean water．

3．Drink the water that has not been boiled．

Many people think boiled water is safe and good to people's health．In fact，it is not true．The boiling point of water is 100℃．By boiling it，most bacteria in water can be killed．In the past，the water was less polluted，so boiling was a good way to make clean water．But heavy metals and other dangerous things in today's water are much more terrible than bacteria．Boiling doesn't fix that problem．And boiling water may give us more of the dangerous things in our glass．

4．Never use soft drinks to take the place of water．

2）Drinking water at about 10 am helps your body keep enough water．

3）Drinking water at about 3 pm can clean out the wastes in your body．

4）About eight o'clock in the evening is the best time to drink water．Your blood gets thicker when you sleep．Water will make your blood less thick．
