Spring is kapha season and the time when kapha transforms from its winter solid state (ice and snow) to its spring liquid state (rain and mud). When the weather warms and melts kapha the same thing happens inside our bodies. For people with imbalanced kapha, the liquid state can make respiratory and digestive symptoms seem worse. Symptoms of imbalanced kapha include morning sinus congestion, dripping nose, watery eyes, low appetite, nausea, and feeling sluggish.
In Ayurveda, both vata and kapha dosha cause colds and flu when they are out of balance and immunity is weak. Excess kapha dosha has the qualities of cool, heavy, and moist which causes runny nose, sneezing and a cough with a lot of phlegm. Excess vata dosha has the qualities of dryness, lightness and moving fast which causes coldness with chills and a dry cough.
