Can hot tea help to prevent glaucoma?
Research has suggested that drinking hot tea may help to reduce the incidence of glaucoma, according to a US study. However, experts point out that no clear causal link has been established and further studies are required.
The study consisted of 1678 participants, 84 of whom had glaucoma. There was no association found between drinking caffeinated and decaffeinated coffee, soft drinks, ice tea and glaucoma. However, participants who drank at least one cup of hot tea per day had a 74% decreased odds of having glaucoma compared with those who did not.
