As we reach the midpoint of winter in Aotearoa, Exercise New Zealand emphasises the importance of staying active and
socially connected to boost your immune system and ward off seasonal illnesses. With colder temperatures and shorter
days, it's easy to fall into sedentary habits, but maintaining regular physical activity and social interactions are
crucial for enhancing our body's defence mechanisms.
The Science Behind Exercise and Immunity
A recent article published in the World Journal of Biology Pharmacy and Health Sciences highlights that engaging in regular moderate-intensity exercise can significantly improve your immune response and
prevent a range of conditions. Activities such as brisk walking, cycling, and swimming enhance the function of various
immune cells, helping the body fend off infections—an especially important consideration during winter when respiratory
infections are more common. Here are three key factors to consider:Enhanced Immune Function: Moderate exercise boosts the immune system by stimulating key immune cells that fight
infections and reduce inflammation.Reduced Risk of Illness: Regular physical activity lowers the incidence, severity, and duration of respiratory
infections, improves vaccine response, and reduces the risk of death from infectious diseases like influenza and
pneumonia.Balancing Exercise Intensity: While moderate exercise enhances immunity, prolonged high-intensity workouts without
adequate rest can suppress it. Balance is key to maintaining optimal immune function.
The Role of Social Interaction
Staying active during winter is not just about maintaining physical fitness; it's about preserving overall well-being. Research has also shown that engaging in activities that include interactions with others, such as yoga classes, group fitness
sessions, or gym visits with friends, provides immense social benefits that have been shown to improve immunity. Social
interaction can reduce cortisol levels, improve sleep, and even lower the risk of dementia. According to Exercise New
Zealand, group-based exercise activities remain highly popular in Aotearoa, with over 85% of exercise providers offering
some form of group activities. These activities not only promote physical health but also foster a sense of community
and support.
Stay Active, Stay Social, Stay Healthy
Exercise New Zealand encourages everyone to stay active and socially engaged this winter. By incorporating regular
physical activity and social interactions into your routine, you can boost your immune system and enhance your overall
health.
