Test your body's acidity or alkalinity. The best way to do that is to check our urine's pH. It is really easy to do. You have to get some pH test strips and moist it with your urine. The strip will immediately show a color which correspond to a pH. The first urine you excrete when you wake up or during the night might have a pH 5 or even under. When we sleep our body gets rid of its acidity. But later in the morning and during the day our urine should have a pH between 7 and 7.5.
