To reduce blood pressure immediately, several effective methods can be used:

• Deep breathing through the left nostril: Sit comfortably, close your right nostril with your thumb, and breathe deeply and slowly through your left nostril for 3 to 5 minutes to relax blood vessels and reduce stress hormones.
• Massaging specific points on the ears, neck, and face: Gently massage the neck from behind the earlobe down to the collarbone, massage a spot 0.5 cm from the ear on the face, and apply pressure on acupressure points just below the base of the skull (GB 20) for 1-2 minutes to relieve tension and improve blood flow.
• Humming "bee breath" (Bhramari Pranayama): Sit comfortably, place fingers on ear cartilage, inhale deeply and exhale while making a humming sound to relax and reduce blood pressure.
• Soaking feet in hot water: This helps move blood away from the head towards the feet, normalizing blood pressure.
• Drink a glass of water: Dehydration can raise blood pressure, so rehydration may help lower it.
• Listening to soothing classical music combined with breathing exercises or meditation can also help lower blood pressure quickly.

These approaches are useful for immediate blood pressure lowering. However, if blood pressure is critically high (above 180/90) or accompanied by symptoms like chest pain, severe headache, dizziness, or shortness of breath, immediate medical attention is necessary.

In summary, techniques focusing on relaxation, acupressure, breathing, hydration, and calming stimuli can reduce blood pressure promptly at home.
