Most people go on camping trips because they're tired of the city or ready for an adventure. Whether you enjoy biking, hunting, or any other outdoor activity, camping offers you a way to focus completely on a hobby for a few days without external distractions. Research shows that some time outdoors can improve your blood pressure, improve digestion and give your immune system an extra boost. When you spend a few days outside, you get some serious health benefits from the extra oxygen and low levels of pollutants.
