Exercise and well-being during COVID 19 - time to boost your immunity

Area of Science:

• Immunology and infectious diseases
• Public health and epidemiology
• Exercise science and kinesiology

Background:

• The COVID-19 pandemic presents significant global health challenges, impacting morbidity and mortality.
• Social distancing and isolation measures affect public lifestyle and health, potentially weakening immune responses.
• A robust host immune response is critical for protection against SARS-CoV-2 infection and severe disease progression.

Purpose of the Study:

• To explore the role of exercise in enhancing host immunity against viral infections, specifically in the context of the COVID-19 pandemic.
• To investigate how physical activity can mitigate the adverse psychological and physiological effects of isolation.
• To advocate for health promotion strategies that encourage physical activity during and after the pandemic.

Main Methods:

• Review of existing literature on coronavirus pathophysiology and immune responses.
• Analysis of the impact of exercise on innate immunity and viral protection.
• Examination of exercise's effects on stress, anxiety, and sedentarism associated with isolation.

Main Results:

• Exercise demonstrably improves host innate immunity, offering protection against viral infections.
• Physical activity mitigates negative effects of isolation, such as stress and anxiety, which can impair immunity.
• Moderate-intensity exercise is recommended within the challenging pandemic environment.

Conclusions:

• Enhancing host immunity and counteracting isolation effects through physical activity is strongly supported.
• Innovative, technology-integrated health promotion models involving government are needed to combat inactivity.
• Proactive strategies are essential to reduce physical inactivity during the COVID-19 pandemic and beyond.
