Stress and immunity: Here's the link

The immune system works against the infections and protects your body from illnesses. Studies suggest that stress can weaken your immune system and make you prone to illnesses.

Dr. Akshay Kumar from Artemis Hospital explains, "The state of mind certainly affects one's state of physical health. The disruption in the state of mind not only raises concern for mental health but also has debilitating effects on physical health. Stress weakens your immune system making you more vulnerable to fall ill."

"Due to stress, your body produces a high level of cortisol hormone, altering the immune system. Your brain gives defense signals to the endocrine system thus releasing the hormones to fend off diseases but the constant hormonal dysregulation caused by stress might affect your health. When the human mind is stressed your immune system further gets compromised due to the body being unable to produce the required lymphocytes (white blood cells) which are an essential part of your immune system to fight off microbes and antigens," he adds.
