Spending time in nature boosts immunity from "summary" of The Nature Fix: Why Nature Makes Us Happier, Healthier, and More Creative by Florence Williams
In the natural world, our immune system gets a workout, which can be a good thing. When we spend time in nature, we expose ourselves to a greater variety of bacteria, fungi, and viruses, many of which are beneficial for our health. This exposure helps to challenge our immune system, keeping it strong and resilient. Studies have shown that people who regularly spend time in natural environments have higher levels of natural killer cells, which are important for fighting off infections and even cancer.
In addition to the direct benefits to our immune system, spending time in nature can also reduce stress, which in turn has positive effects on our overall health. When we are stressed, our body releases cortisol, a hormone that suppresses the immune system. By immersing ourselves in natural settings, we can lower our cortisol levels and allow our immune system to function more effectively.
Furthermore, being in nature encourages physical activity, whether it's hiking through a forest, swimming in a lake, or simply taking a leisurely stroll in a park. Exercise is known to boost the immune system by increasing circulation of white blood cells and antibodies, which help to fight off infections. The combination of physical activity and exposure to the natural world creates a powerful synergy that can have lasting effects on our health.
It's important to note that the benefits of spending time in nature on our immune system are not limited to just a few hours here and there. To truly reap the rewards, we need to make nature a regular part of our lives. Whether it's a daily walk in the park, a weekend camping trip, or simply opening a window to let in some fresh air, finding ways to connect with the natural world can have profound effects on our health and well-being.
