Exercise is well-known to be beneficial to both physical and mental health, and most of us should be doing more of it. However, if you’re more of a lazy slob than a marathon runner, you may need a little more encouragement to put on your running shoes. Even with social distance rules in place, many gyms are still closed—or we don’t feel comfortable coming to gyms that have resumed.

And, in many areas of the country, the cold temperatures make going for a jog a chore. But what if exercise also had the capacity to increase immunity, a lesser-known advantage that could motivate you to get moving?

There has never been a time in recent history when our immunity and ability to fight disease has been more important than during COVID-19. Getting active, it turns out, may play an important role in supporting the immune system and fending off sickness.

Let’s admit it: there’s no such thing as a miraculous pill or supplement that can grant you immunity.

That isn’t to imply that lifestyle factors such as exercise and physical activity don’t influence how your immune system functions. However, it isn’t as easy as “run a mile, kill a bug.” Here’s everything you need to know about exercise and your immune system, especially now that the new pandemic is spreading.

How Exactly Does Exercise Affect Your Immune System?

Although exercise has an effect on your immune system, thinking of it as a “natural immune booster” isn’t entirely accurate.

Here’s what’s going on: Your body perceives any physical exercise that raises your heart rate for an extended period of time as a form of physiological stressor, such as a 30-minute stroll or sprint, a bike ride, or even some tennis volleying. As a result, it mobilises white blood cells such as neutrophils and lymphocytes (especially T-cells and natural killer cells) from various parts of your body to flood your bloodstream.

These cells begin to diminish in your bloodstream shortly after your exercise and even drop below resting levels. Experts initially thought this was proof of immunosuppression, but better lab techniques revealed that these cells were simply being deployed to other physiological regions where they consistently perform an immune monitoring mechanism.

This entire immune system jumpstart is just temporary—say, three hours—but it happens after each session of moderate to strenuous exercise. So, if you keep exercising on a regular basis, you’ll continue to feel those effects after each workout.

Do the physiological reactions, however, translate into real-world advantages? People who exercise regularly are less likely to become ill, according to research. People who worked for at least 20 minutes per day, five or more days a week, reported 43 percent fewer days with upper respiratory tract infection symptoms than those who were inactive, according to a 2010 study of more than 1,000 adults published in the British Journal of Sports Medicine. When they did get sick, their symptoms were usually milder.

That isn’t to imply that exercise will automatically trigger your immune system to destroy every germ invasion it encounters; rather, it will assist you boost your chances of fending it off.

Exercise Boosts Immunity And Can Help Fight Off Infections 

Your immune system benefits from exercise in a variety of ways. It can improve blood flow, eliminate bacteria from your airways, induce a temporary rise in body temperature that may be beneficial, build antibodies to help prevent infection, and lower stress hormones.

Exercise decreases inflammation, enabling the immune system to function more effectively. While acute inflammation in reaction to injury is a normal aspect of the immune system, persistent inflammation can cause the immune system to become sluggish.

Exercise acts like an immunity booster and immunological markers when done on a regular basis. Interleukin 6, a protein that aids the body’s response to damage, is one of the improved markers.

According to a 2019 scientific assessment, moderate-intensity exercise is connected to a lower risk of upper respiratory tract infections, such as the flu and the common cold.

For instance, a 2018 Chinese research of 1413 participants found that those who exercised at least three times per week had a 26 percent lower chance of having a cold.

When compared to people who did not accept the exercise instruction, those who were given an eight-week schedule of moderate exercise had a 14 percent lower risk of acute respiratory infection and a 23 percent lower number of sick days, according to a 2018 research of 390 participants.

Healthy individuals should strive for at least 150 minutes of moderate activity per week, according to the Centers for Disease Control and Prevention (CDC). This can include things like walking, yoga, or gardening.

Small quantities of exercise, on the other hand, can help to increase immunity.

With stay-at-home orders in place and facilities closed, working out during the pandemic can be difficult. The most important thing is to stick to social-distancing norms – while exercise can help you build immunity and responsiveness, it won’t completely protect you from being sick if you are directly exposed to germs.

You may perform a variety of worthwhile exercises both inside and outside your home, including:

  • Chair exercises
  • Resistance band exercises 
  • Isometric exercises
  • Ab workouts
  • Full body exercises 
  • Yoga

People in many states are now allowed to exercise outdoors. Just remember to allow at least six feet of distance between you and everyone else if you workout outside.

Furthermore, having a workout companion will help you exercise more frequently, and having a gym buddy is still possible today.

Regular exercise is the bedrock of a healthy lifestyle. It offers numerous advantages, including improved cardiovascular health, lower blood pressure, and weight management. Is it, however, a natural way to strengthen your immunity and maintain it healthy?

Exercise, when combined with a well-balanced and healthy diet, can improve overall health and thus aid in the maintenance of a healthy immune system. It also helps directly by improving the body’s blood circulation, which permits the immune system’s cells to move around the body far more easily and efficiently.
