Can daily yoga lower your blood pressure over one week? You divide 20 participants into two groups. One group watches television for two hours each day. The other group practices yoga exercises, breathing techniques, and meditation for the same time.
You measure each group's blood pressure right after their sessions for seven days. The television group shows a slight rise in blood pressure. The yoga group shows a steady decline after a few days.
Hypothesis
The hypothesis is that persons who have been practising yoga will have reduced blood pressure.
The force blood exerts against artery walls shifts depending on what your body is doing. Relaxation practices like yoga may reduce that force over time. In this experiment, 20 male participants are divided into two groups — one watches television for two hours each day, the other practices yoga exercises, breathing techniques, and meditation for the same time. You measure each group's blood pressure with a portable wrist monitor after their sessions for seven days. The yoga group shows a steady decline after a few days. The television group, by contrast, shows a slight rise. That pattern suggests sustained physical and mental relaxation can lower the force blood pushes against vessel walls.
Your body reacts to change, but a calming routine can reshape that reaction. You divide 20 participants into two groups. One group watches television for two hours each day. The other practices yoga, breathing, and meditation for the same time. You measure each group's blood pressure right after their sessions for seven days.
Method & Materials
You will divide the participants into two groups and measure their blood pressure with a portable wrist blood pressure monitor. The first group will watch television for two hours and the second group will practice yoga for two hours.
You will need a yoga instructor, a television set, 20 male participants between the ages of 35 and 45, and a portable wrist blood pressure monitor.

The results of the experiment showed that the participants in the yoga group had a decline in their blood pressure after a few days, while the participants in the television group had a slight increase in their blood pressure. This proves that the hypothesis that persons who have been practising yoga will have reduced blood pressure is true.
Why do this project?
This science project is interesting because it shows how yoga can be used to reduce blood pressure, which is a common health issue.
Also Consider
Variations of this experiment could include different age groups or female participants, or comparing the blood pressure with other activities like listening to soft music, aroma therapy or practicing tai chi.
