Nature has a significant impact on our immune system. Spending time in nature and being exposed to natural environments can help boost our immune system. The fresh air, sunlight, and natural surroundings can reduce stress levels, stimulate the production of vitamin D, and increase the activity of immune cells, all of which contribute to a stronger immune response. In addition, exposure to diverse microbial environments in nature can help train our immune system to better recognize and respond to pathogens. Therefore, regular contact with nature can play a vital role in supporting a healthy immune system.
