Prof. Benjamin Murphy, Ph.D.Long-term exposure to stress can harm your immune system. Increased cortisol diminishes white blood cells and antibodies, thus increasing your chances of getting an infection. Clients have indicated higher incidents of illness while stressed. The body has a basic instinct to survive, compromising protection.
Fight-or-flight responses divert resources from immune function. Blood pours into the muscles, therefore limiting flow into the lymph nodes. Digestion is slowed down, hindering nutrient absorption. Breathing shallowly limits oxygen delivery for cell repair. These physiological changes weaken defenses significantly.
Breath control decreases cortisol levels almost instantly. Try breathing in for four seconds, hold for seven seconds, and exhale for eight seconds. Repeat this five times when you feel stressed. You will quickly reset your nervous system. Meditating daily can also help reduce inflammation levels.
Exposure to nature is associated with a significant boost to natural killer cells. Consider taking 20-minute walks in green spaces. Sunlight provides vitamin D, which plays a crucial role in regulating the immune system. Aim for a combination of physical activity and outdoor exercise. The combination creates double protection.
Mindfulness rewires stress responses over time. Daily gratitude journaling reduces anxiety markers. Body scans identify tension early. Progressive muscle relaxation before bed helps. Consistency matters more than duration.

Integrating your lifestyle helps manage stress consistently. Pair habits to routines you already have in place. For example, practice deep breathing while you wait for coffee. Journal while you commute to work. These are examples of anchor strategies I teach my clients. Small changes, done consistently, increase resilience.
