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. This means that the body is functioning within a healthy range.
It is also possible to have acid urine after an intense physical exercise since during the effort our body releases important amounts of lactic acid, or after being seated too long in a room. A walk outside usually brings back our urine pH between the healthy range.
While we are walking in a well oxygenated area, our body burns the acids and excretes them via our lungs.
