However, not all coffee is good for everyone. If you have Kapha dosha, you may want to think twice before drinking coffee. While coffee can help to improve mental alertness and focus, it can also increase anxiety and restlessness in people with Kapha dosha. Coffee is also a diuretic, which means it can promote dehydration and upset the delicate balance of fluids in the body. If you do choose to drink coffee, make sure to drink it in moderation and to stay hydrated throughout the day.
