Since asthma involves tightening of the airways, causing difficulty in breathing, one of the best home remedies to prevent asthma is to practice breathing exercises.

  This technique involves inhaling through your nose and exhaling through the mouth with lips being pursued, leading to a whistling sound.
• Yoga
