A recent study found an association between drinking hot Turkish tea and eye pressure. Glaucoma, or colloquially eye pressure, is a condition usually seen in patients over the age of 60. Although the cause of the disease is structural, in some cases it can also occur due to cortisone use, diabetes or trauma. Glaucoma begins with intraocular pressure reaching a level that will reduce blood flow to the eye.

The cause of the disease is usually caused by genetic characteristics. Glaucoma, on the other hand, is known for being a slow-progressing disease. It is estimated that there are about 57.5 million people with eye pressure in the world.

As researchers investigate the question of whether caffeine affects pressure inside the eye, they note that there are findings that drinking hot tea reduces the risk of glaucoma. In a paper published in the Turkish Journal of Ophthalmology, researchers in Turkey examined the results of eye examinations in 1,678 participants aged 40 and older.

It was also investigated how often participants consumed coffee, hot tea, soft drinks, whether caffeinated or not. As a result, a total of 84 participants had glaucoma. Most of them were observed to have diabetes and few had a smoking habit.

But the team concluded that glaucoma is linked to hot tea. The study concluded that people who drank more than 6 cups of hot tea a week were less likely to have eye pressure, even when conditions such as age, body mass index, diabetes and smoking habits were taken into account.

Individuals who consumed hot tea were 74 percent less likely to suffer from glaucoma than those who did not drink it. It was also noted that there was no link between cold tea and glaucoma. On the other hand, those who conducted the study said that it is difficult at the moment to come to any final conclusions.
