Hot tea reduces the risk of developing glaucoma

The authors of the new study say that the risk of glaucoma was lower in people who drank hot tea every day.

Risk factors for glaucoma include age, diabetes, obesity and hypertension. Coffee consumption have been linked to an increased risk of developing glaucoma. However, the research results were divided, with some researchers indicate that moderate coffee consumption does not affect the risk of developing glaucoma, and others have received mixed results. In addition, some studies have suggested that the consumption of caffeinated drinks can also affect the risk of developing glaucoma.

The researchers decided to investigate how the consumption of different drinks, including hot tea, coffee and soft drinks, affects the risk of developing glaucoma.

“The purpose of this study,” scientists say, “to study the relationship between the consumption of different beverages with caffeine and without caffeine and glaucoma”.

Materials and methods

The study’s lead author Connie Wu (Connie Wu) analyzed data from 10,000 people. The study used a number of tools, including physical examination and blood samples. 1678 participants agreed to share the full results of ophthalmologic research methods, and of these 84 people suffered from glaucoma.
The researchers studied how much coffee and hot tea with caffeine and no caffeine, alcoholic and non-alcoholic beverages the participants drank over the past year, and how often they drank.

The scientific results

Researchers found that participants who drank hot tea every day, 74% decreased risk of developing glaucoma.
There was no relationship between the risk of developing glaucoma and other beverages, including coffee with caffeine and decaffeinated, and tea, decaf and soft drinks.

The study authors note that “tea contains phytochemicals and flavonoids, which have anti-inflammatory, anticarcinogenic, antioxidant and neuroprotective properties, which is associated with prevention of cardiovascular diseases, cancer and diabetes”.

Thus, researchers believe that drinking tea could have a protective metabolic effect. They also cite studies that suggest that glaucoma may develop under oxidative stress and neurodegeneration associated with aging and decay at the cellular and molecular levels. Taking into account the protective effect of hot tea, when it comes to cellular aging, the researchers suggest that further efforts should be aimed at the study of this drink.
