This video by Dr. Rajesh Kumar discusses the vital role of serotonin, often called the “happy hormone,” in maintaining mental peace and overall health. Serotonin acts as both a hormone and a neurotransmitter, regulating mood, sleep, memory, appetite, and even digestion and wound healing. Interestingly, the doctor highlights that 90-95% of the body’s serotonin is produced in the gut, not the brain, making gut health crucial for emotional stability.
