According to Ayurveda, human health is determined by three factors, known as the three doshas (tridoshas), namely - vata, pitta and kapha.
Low emotional states can occur due to a significant shift in the levels of these three doshas. Additionally, lack of awareness of one’s inner self can also lead to an emotional imbalance.
Majorly, according to Ayurveda, depression is a result of kapha imbalance. Plus, changes in the brain’s electrochemistry can encourage a vata shift, which may also trigger a loss of enzymatic activity in the metabolism (also known as a shift in pitta).
In these three doshas, kapha imbalance can lead to heaviness, darkness, anxiety, and stress, often leading to hopelessness and sadness.
