What can an individual do to reduce their risk of a severe case of COVID-19? In the absence of a cure, improving the health of an individual, especially pulmonary health, is important. Hydration, balanced nutrition, appropriate exercise and regular sleep may help. Once an individual is infected, fresh air and cleaning the environment is recommended. This helps protect those who interact with a patient in-home or healthcare settings. It also reduces re-exposure to viral particles that the individual may cough, sneeze or breathe out. Rebreathing viral particles may lead to infection of other parts of the lung and increase the viral load.
Attention to wellness during the mild period of COVID-19 may impact whether it becomes severe. Among the well-established means of strengthening the immune response to many viruses are elevated hydration, balanced nutrition (chicken or egg drop soup!), good sleep habits, and not interfering with elevated temperature unless it exceeds safe limits (103◦F, 39.5 ◦C). Improving respiratory health before becoming infected, should also improve outcomes.
Good ventilation and frequent cleaning of the environment of individuals that are ill with COVID-19 is widely recommended by health authorities. This is critical for anyone who must interact with a patient, whether family members in the home or healthcare providers in medical settings. It may also provide benefits through reducing re-exposure of the individual to viral particles, which may affect pulmonary tissue that is not yet infected or has been recently cleared by the immune system.
Deep breathing has been shown to improve respiratory health and patient outcomes across a number of conditions. While more intensive chest physiotherapy has not been found effective in treating hospitalized pneumonia patients, for mild symptoms standard breathing exercises may be beneficial.
In about 80% of cases, COVID-19 has only mild symptoms and individuals recover without requiring significant medical intervention. In 20% of cases, the disease becomes severe, 10% require Intensive Care to survive, including ventilators. and 2- 4% of cases result in death. The outcome is also sensitive to underlying cardiovascular health and risk increases dramatically with age. In a typical case the disease begins mild, and after several weeks suddenly progresses to become severe. A competition between viral replication and elimination by the immune system underlies disease progression. Sudden onset of severity indicates that the battle reaches a transition (tipping point) to a lethal phase. This may be due to the extent of damage to lung tissue, the overload of some capacity of the immune system, auto-immune impacts such as a Cytokine storm, or other mechanisms. The sensitivity of the transition to multiple factors suggests that even a small change in individual conditions may shift the balance. Strengthening the immune system or reducing the ability of the virus to spread across the pulmonary tissue may be helpful.
The coronavirus spreads via droplets from coughs, sneezes and exhaled air of individuals who carry the virus (regardless of whether they show symptoms). The following recommendations to improve pulmonary health and reduce exposure/reexposure to viral particles are safe for individuals in reasonable all-around health. Anyone with specific health concerns or respiratory issues may wish to consult their chest specialist in Nagpur before adopting them. Please note that these recommendations will not substitute for prevention, we only hope that they may reduce the severity in some cases.
Recommendations
Aerobic exercise. Before infection aerobic exercise strengthens cardiovascular health. Once infected, during the period of mild symptoms, moderate daily aerobic exercise can improve lung ventilation. Such exercise may benefit immune function as well. Ideally, do this exercise outdoors or with open windows or otherwise well-ventilated areas. Insufficiently warm climates long walk or even running may improve lung capacity. Jumping jacks, jogging in place, or dancing can be done even in small spaces.
Keep windows open where temperatures allow. It is best for airflows to be outward, and surely not to allow airflow from an infected individual toward spaces where uninfected individuals are present [5]. This has two benefits: allowing any viral particles present in the air to exit the room, rather than you (or someone else) breathing them back in; bringing more oxygen into the room—helpful for the lungs and all-around health. If the weather in your region is cold, consider opening the window at least a small amount while also running a heater. Air purifiers may also be helpful.
Spend time outdoors (without approaching others within 6 ft. Balconies, back yards or patios, are good locations to be, as well as walks while avoiding proximity to others. This has the same benefits as keeping windows open—ensuring exhaled viral particles don’t get re-inhaled.
Breathe in through the nose. Breathing through the nose helps clean incoming air, via cilia (small hairs) and mucous membranes, thus creating a shield against disease. Nasal breathing also warms and moistens incoming air.
Deep breathing. Deep breathing and exhalation bring fresh air in and can improve lung capacity. We typically breathe in and out only a fraction of our lung’s capacity. Expelling viral particles from the more stagnant areas of the lung may further decrease self-exposure to viral particles. Deep breathing is often recommended by the best hospital in Naagpur for health and well being and can be done multiple times a day on a regular schedule.
Avoid viral rebreathing. Outdoors or with open window: Breath out, turn to breathe in clean air. Repeat multiple times, and periodically. Where fresh air is not available, use HEPA air purifier day and night.
Additional lung health practices. Many additional exercises can be found for enhancing respiratory health. See Rush University Medical Center recommendations for more nuanced exercises.
Clean surfaces and wash clothing and bedding. Frequent washing removes viral particles that are deposited on surfaces and clothing and prevent exposure or reexposure
