Correct Answer is A

Explanation

A) Correct answer. Deep-breathing exercises are a relaxation technique that can help reduce stress and lower blood pressure. Deep breathing triggers the relaxation response, leading to decreased heart rate and blood pressure.

B) This option is incorrect. While regular exercise is beneficial for managing hypertension, high-intensity workouts may not be the best choice for stress reduction. Low to moderate-intensity exercises are more effective in promoting relaxation.

C) This option is incorrect. Consuming alcohol can have negative effects on blood pressure and overall health. It is not a recommended relaxation technique.

D) This option is incorrect. Social interactions and maintaining a support system are essential for mental well-being. Limiting social interactions may lead to increased stress and feelings of isolation.
