Gratitude not only affects your Attitude but your Resilience

We’ve all heard the saying, “mind over matter,” but putting the cliche into practice might help you avoid sickness.

Research suggests that your thoughts and feelings influence your immune system’s ability to function properly and keep you healthy. 

The study examined how emotional experiences, such as stress, joy, and sadness, are tied to immune responses. Researchers found that negative emotions, especially chronic stress, can suppress immune function, leading to higher susceptibility to illness. 

On the flip side, positive emotions—like happiness, gratitude, and a sense of purpose—can boost immune markers, improving your body’s natural defenses.

The study is just one in a long line of research that connects your thoughts to your health. For example, chronic stress is linked to elevated cortisol levels, a hormone that suppresses immune function over time. And people who reported higher levels of joy and satisfaction have stronger T-cell activity (critical for fighting infections) and better-regulated inflammatory responses.

This doesn’t mean you can’t be sad or angry. Instead, it’s about awareness to avoid rumination or staying in a negative state of mind. Research suggests that merely recalling your anger can reduce the antibody immunoglobulin A — your first line of defense against illness — for up to six hours.

The research emphasizes the importance of psychological well-being, showing that mental health interventions like mindfulness, therapy, or even small acts of kindness can enhance immune function and performance.

The next time you feel stressed, take a few minutes to meditate or practice gratitude. If you lack joy, connect with loved ones, spend time in nature, exercise, or watch your favorite comedy special or sitcom. Even small efforts to improve your emotional state can help support a healthier immune system.
