How to keep your immune system strong
💙Eat as many fresh fruits and vegetables as you can, every day.
The micronutrients they provide ensure you aren’t missing key nutritional components, like zinc and vitamin A, that your immune system needs to fight off invading microbes. Note that most supplements are not superior to the nutrients you can get from food.
The fiber from fruit and vegetables can help your gut’s microbiome produce important compounds for a healthy immune system.
💙Stay physically active with walks and exercise.
Studies show the immune system is very responsive to exercise. Exercise and immune regulation are interrelated and affect each other. Exercise changes immune regulation by affecting cells and has anti-inflammatory effects.
💙Sleep for at least seven hours a night.
When the body does not get enough sleep, the immune system is negatively affected.
Sleep loss reduces natural killer cell activity, which increases the risk for cancer and viral infections; generates production of inflammatory cytokines, which increases the risk for cardiovascular and metabolic disorders; and reduces production of antibodies, which increases the risk for infections.
💙Minimize stress.
Stress of all sorts—psychological and physical—directly weakens parts of your immune system, increasing risk for infections or reactivation of viruses inside you. Shingles, a painful rash that arises from the reactivated chickenpox virus, often flares up when people are experiencing chronic stress.
Stress can also cause "patrols" in your immune system—certain cells that tell the immune system to wind down an attack—to fail. When this happens, too much inflammation can occur. Hives are one example of a stress-induced breakdown in the immune system’s patrols.
💙Drink less alcohol.
Alcohol disrupts immune pathways that can impair the body’s ability to defend against infection, contribute to organ damage associated with alcohol consumption, and impede recovery from tissue injury.
💙Do not smoke.
Smoking exacerbates pathogenic (disease-causing) immune responses and/or reduces immune defenses.
