What is a benefit of being outdoors during physical activity?

Being outdoors during physical activity offers numerous benefits, one of the most significant being exposure to natural lighting. Natural light, particularly sunlight, plays a crucial role in regulating our circadian rhythms, which can enhance mood and energy levels. This exposure helps the body produce vitamin D, which is vital for bone health and immune function. Additionally, engaging in physical activities outdoors often improves mental well-being by reducing stress and anxiety, increasing feelings of happiness, and fostering a connection with nature.

The other options do not present benefits of being outdoors; rather, they highlight limitations associated with indoor environments or activities. For instance, indoor air pollution can negatively impact health and performance, isolation can lead to feelings of loneliness, and indoor gameplay improvement does not capture the advantages gained from outdoor physical activity. Thus, natural lighting stands out as a clear benefit of exercising outdoors.
