Spiritual research shows that drinking water that is boiled and cooled is good for health according to Ayurveda !

When water boils, it is purified by the sanskar of fire which did not happen in the water kept in the refrigerator. The tap water in the study originally had Sattvikta; but when that water was kept in a cold atmosphere (refrigerator), its Sattvikta reduced. This shows that drinking water that has been kept in a refrigerator is not spiritually beneficial.
