When we are outside, studies show evidence of significant improvements to our mood, stress levels, confidence and self worth, relationships and physical and mental health. And yet many of us aren't making use of the myriad benefits the natural world can offer us. Bear Grylls is here to change that. In Rewild, Reboot, Recharge Bear lays out a challenge, to dedicate 90 days to nature. By taking regular, achievable steps to reduce the amount of time spent on screens, indoors, and at desks, you too can experience the powerful, life-affirming impact being outside will have on everything you do. This book is about walking barefoot, growing something, learning something. It's about turning our faces towards the sun and reminding ourselves who we really are.
