Aggravated Kapha (water) accumulates in the airways, leading to their narrowing and obstruction. This causes an interruption in the flow of the air in the lungs, causing shortness of breath and difficulty in breathing. This happens because of increased intake of vata (air) and kapha aggravating foods, internal weakness of lung tissues, and various diseases affecting the lungs. Factors like living in a cold and damp atmosphere, having cold or stale food or drink, eating foods that are not easily digestible, and ama (mucus) formation that blocks the respiratory channels also causing difficulty in breathing.
