1. Sleep

Sleep plays a vital role in improving health and boosting the immune system (7). It helps in redistributing the energy to help the brain and muscles enrich the immune functions. During this phase, the brain recharges itself, cleans up toxins, and promotes overall health.

Sleeping helps in inhibiting the inflammation by reducing the potency of toxic compounds. Besides, it creates an environment for perfect hormone secretion, which promotes the health of various organs in the body. All these factors enable the immune system to utilize significant amounts of energy that helps in building and regulating a proper immune system. 

On the other hand, poor sleep can lead to irritability, fatigue, headaches, and disrupt normal functions. In such cases, the immune system’s energy is redirected into warding those conditions of which can reduce your body’s capability to fight any foreign pathogens in your body.

In general, it is suggested that a person must have a regular routine of 7 to 9 hours of sleep every day. Hence, proper sleep can build your body’s defense mechanism against coronavirus, flu, or other diseases.

2. Exercise

Regular exercise of 30 minutes a day can be very beneficial in boosting the immune system. It, in turn, can help the body fight off infections. Besides, sweating during exercise can flush out pathogens or toxic compounds that can otherwise damage your health. Exercises exhibit a positive response on antibodies and WBC to circulate more rapidly, which can detect illnesses in earlier stages and prevent infections.

Lunges, skipping rope, sit-ups, and push-ups are some of the best exercise that you can practise at home. 

Exercising your lungs speeds up the recovery process. Practicing breathing exercises can increase oxygen levels and remove stale air from the respiratory tract (8).

3. Stress-free

Chronic stress levels impede the immune system (9), which can disrupt the body’s healing and recovering process against diseases and infections. When stressed, the immune system loses its ability to ward off viruses, bacteria, and other pathogens. It, in turn, makes the body more susceptible to infections. When the body is free of psychological stress, the immune system works at its optimal level. It can help in fighting colds, flu, fatigue, and even in enriching the body’s ability to fight conditions like coronavirus. 

Besides, when any pathogens or diseases infect you, it is essential to keep your mind stress free. If you’re stressed, your brain focuses on promoting neurotransmitters to keep uplift or regulate your mental health. On the other hand, if your psychological levels are healthy, your brain and body have a much higher capacity to fight off pathogens.
