Brief Summary

Background:

Tea is a universal beverage and one of the most popular drinks around the world. Some cell and animal experiments have pointed out that drinking tea may be related to hypotension, body composition and vision problems, and there are more and more related advertisements, especially for hibiscus tea, which is rich in anthocyanins. However, there is a lack of literature on the effectiveness of hibiscus tea drinks in preventing and treating blood pressure, body composition and vision problems in college students.

Purposes:

This study used a randomized human trial to evaluate the effects of drinking hibiscus tea on the control and reduction of blood pressure, body composition, and near vision problems. 100 subjects were divided into 2 groups: the hibiscus tea group and the boiled water drinking group, and they continued to drink it for 10 weeks. At the beginning of the trial (week zero), the second week, the sixth week, and the tenth week after stopping drinking, the visual fatigue scale, blood pressure, and body composition were examined respectively. At the initial stage (0th week) and at the 10th week after stopping drinking, visual acuity examinations were performed.

Expected results:

1. To explore the effect of hibiscus tea drinks on subjects' myopia.

2. To explore the effect of hibiscus tea drinks on visual fatigue of subjects.

3. To explore the effect of hibiscus tea drinks on the blood pressure of subjects.

4. To explore the impact of hibiscus tea drinks on the body composition of subjects.

5. To explore the effect of hibiscus tea drinks on body fat of subjects.
