If you love hiking in the mountains, camping and fishing at a favorite lake, or just going for a walk in the woods, you likely already know that time in nature does a world of good for both physical and mental health. Researchers at the University of East Anglia performed a meta-analysis of more than 140 studies completed in 20 countries that objectively confirms these subjective impressions. Exposure to wild spaces reduces the production of stress hormones, lowers pulse rate and blood pressure, decreases sleep disturbances, and increases happiness, well-being, and even creativity. For many people, spending time in the great outdoors, whether for an afternoon or weeks at a time, means a break from technology. But there are so many practical benefits of having your phone with you! So before you escape to the woods to eat roots and berries and forget human speech, think about adding some of this essential camping gear and equipment to your packing list.
