A healthy lifestyle must include both Physical Activity (PA) and nutrition since they can affect energy balance, enhance the functionality of numerous systems, and boost immunity. The most frequent and widespread threats to human health, infections and the symptoms that go along with them, have negative effects on society and the economy all around the world. The severe aging related alterations and dysfunctions of the human immune system are referred to as immunosenescence. Immunosenescence is the clinical term for the ageing immune system that makes people more susceptible to diseases and decreases the effectiveness of vaccines. Such a phenomena is associated with weakened immune responses that result in the failure of numerous organs, while sedentary lifestyles, gradual muscle loss, and concurrent declines in muscular strength promote immunosenescence and inflammation. In this overview, we've spoken about how nutrition and PA can strengthen the immune system both separately and together. There is evidence that long term PA helps the immune system develop and protects against many infections. We've also covered a number of dietary tactics for strengthening the immune system. Sadly, the evidence that is now available yields contradictory findings. Regarding interactions with food consumption, PA does not typically lead to an increase in energy intake over a brief period of time. But it seems that treating nutritional deficits is the most sensible advice. One can meet the biological requirement of adequate nutrition, which has a substantial impact on the immune system, by consuming a balanced, nutritious diet. It's generally not a good idea to take a single nutrient supplement in the form of food. An appropriate nutrient intake may be achieved by substituting different fruits and vegetables, whole grains, proteins, and probiotics. Therefore, persons who are deficient despite eating a decent diet may benefit from multi nutrient supplementation. Supplementing with probiotics, bovine colostrum, plant derived goods, and functional meals may also aid the immune system in addition to PA.


Physical Activity (PA) • Immunosenescence • Mobilisation nutrition • Multinutrient • Cardiovascular disease • Obesity


Physical Activity (PA) and a balanced diet are important lifestyle elements that affect lifelong health by enhancing body composition, musculoskeletal health, physical and cognitive function. The prevention of metabolic illnesses like obesity, diabetes mellitus, and cardiovascular disease also depends on healthy nutrition and physical activity levels. Lack of physical activity is a substantial risk factor for mortality worldwide, according to the WHO. They said that while some physical exercise is preferable to none, greater physical activity is better for achieving the best possible health outcomes. Contrary to popular belief, combining diet and physical activity can have more significant good health effects and strengthen the immune system than either strategy alone. This is true even though the health benefits of nutrition and physical activity are typically examined separately. Compared to a sedentary lifestyle, regular moderate exercise has been found to lower the risk of infection. Similar to this, a significant, comprehensive examination of data from 195 nations demonstrates that a poor diet with inadequate nutrition is associated with negative health effects. Improvements in fitness, general health/well-being, and perceived quality of life are just a few of the benefits of a healthy lifestyle (including physical exercise and diet) that have been well-documented.


Although important, the advantages to immunity and infection susceptibility are sometimes overlooked. The most typical and frequent presentation is infection, which can have serious economic and social repercussions. This includes respiratory tract infections and the symptoms that go along with it. Additionally, it has been noted that extended exercise sessions and rigorous training are associated with a higher risk of infection. Acute bursts of intense activity temporarily impair immunological function, which can persist for up to 24 hours following the workout. Throughout a person's lifespan, the PA or nutritional requirement changes depending on the stage of development they are in and gradually declines as they get older. Immunosenescence is the term for age related quantitative and qualitative changes in the immune system.

Immunosenescence, as used in medicine, is the slow decline of the immune system that is typically seen with ageing and is associated with greater susceptibility to infections, increased viral reactivation, decreased vaccine effectiveness, and weakened immunological responses that result in diseases. As a result, the majority of older persons are more likely to die from having numerous chronic diseases, and they also tend to have poorer health and disabilities as a result of the toll that chronic diseases have had on their bodies. Costs for social services and healthcare are predicted to be affected. Immunosenescence and inflammation are facilitated by inactivity, the gradual loss of muscle mass, and the corresponding drop in muscle strength.

There is little information on the early history of immunological alterations associated with physical activity and the significance of nutrition. Evidence suggests that sustained Physical Activity (PA) is advantageous for immunological boosting and infection prevention, despite the fact that research into the immune system's reactions to exercise and physical activity is still ongoing. In this overview, we've spoken about how nutrition and PA can strengthen the immune system. We've also spoken about PA, exercise, and how these things relate to different nutritional approaches to boosting the immune system.


The findings implies that there is not enough information to make firm judgments on which diets can significantly strengthen the immune system. Although the magnitude of resistance exercise's impacts on immune function is yet unknown, the majority of research indicates that lifestyle elements including particular food preferences, physical activity, and nutrition have an impact on the inflammatory profile (risk of infection). Additionally, it is linked to behavioural interventions that enhance participant’s immunological and general health in both co-operative and independent ways. On the other hand, it is well known that the prevalence of chronic diseases is increasing globally at an exponential rate, calling for long term systemic policies to boost levels of daily physical activity. However, exercise is a proven method for boosting immune system function and reducing the risk of immunological ageing that is maladaptive. According to this viewpoint, engaging in regular physical exercise seems to be the most effective way to prevent cellular immunosenescence and inflamm aging.

Particular meals and supplements may also strengthen immunity, which lowers the chance of respiratory tract infection. Other supplements, including probiotics, Echinacea, polyphenols, and bovine colostrum, may also significantly strengthen the immune system, according to some new research. Additionally, this study implies that a sufficient diet of a wide variety of healthy fruits and vegetables can compensate for a nutrient shortfall.

Parallel to this, healthcare professionals and public health policymakers should promote physical activity for all people, but especially for older adults and other at risk people, like those with chronic diseases associated with ageing and lifestyle, and for those who are at high risk of developing such diseases. Therefore, more short and long term controlled, randomized interventional clinical trials combining various exercise routines with dietary practices are required to pinpoint additional moderating factors, comprehend the processes underlying immune cell mobilization and infection resistance, and direct clinical practice. This approach would enable a more individualized method of care, which would enhance the effectiveness and acceptance of currently accessible medicines.
