Benefits of water for the kidneys

Water offers many health benefits for the kidneys compared to sugary drinks with high calories. Evidence also indicates that maintaining body moisture may reduce the risk of urinary tract infection and kidney stones; [1] They are lumps of minerals that accumulate in the urinary system, yet little evidence, such as a systematic review published in the Cochrane Systematic Review in 2012, indicated that increased water consumption could contribute to reducing the risk of developing kidney stones again.
