  Sit straight in an upright position. Then take a slow and long breath through your nose. As you breathe, you should allow your belly to expand. Then slowly exhale, allowing your belly to retract. While doing this, you should exhale twice the time that you inhale.
• Pursed Lip Breathing Technique
  This technique involves inhaling through your nose and exhaling through the mouth with lips being pursued, leading to a whistling sound.
• Yoga
  Pranayama is a technique practiced in Yoga, which is highly beneficial for asthmatics. It involves a set of breathing exercises that include breathing through alternate nostrils and controlled breathing.
