A new study says no.
The study, published in Acta Ophthalmologica, tested the hypothesis that greater habitual water intake is associated with lower risk of dry eye disease (DED).
The study details.
The study included more than 51,000 participants from the population-based LifeLines Cohort Study (mean age = 51.2 years).
DED was assessed using the Women's Health Study dry eye questionnaire. Water intake was calculated based on food frequency questionnaires.
What did they find?
Greater water intake was not tied to reduced risk of DED. Rather, it was associated with a modest increased risk of DED. Interventional studies are needed to fully understand the effect of water intake on DED, but this study found no evidence that greater water intake is beneficial.
