Expression of Genes Relating Hypertension and Efficacy of 4-7-8 Breathing Control on Reducing Blood Pressure

Participants in the deep breathing group will be randomized to receive a diaphragmatic deep breathing program. They will be instructed to practice deep breathing at a rate of 6-10 breaths per minute for 15 minutes, twice daily, every day for a duration of 3 months.

Participants in the 4-7-8 breathing group will be randomized to receive a 4-7-8 breathing program. They will follow the 4-7-8 breathing training program, which involves inhaling for 4 seconds, holding the breath for 7 seconds, and exhaling for 8 seconds, counted as one cycle. This pattern is to be repeated for 6 cycles to complete one set. They will perform 12 sets per day-6 sets in the morning and 6 sets in the evening-with normal breathing between each set. This routine will be carried out daily for a duration of 3 months.

Participants in the slow breathing with device group will be randomized to receive a slow breathing with device. They will undergo deep breathing training using a resistance-based breathing device called BreathMax, set at 25% of their maximal inspiratory pressure. The breathing rate will be 6 breaths per minute, continuously for 15 minutes, twice a day. This routine will be performed daily for a duration of 3 months.
