- One of the challenges to happiness is over thinking. When we focus too much on ourselves we can spiral into overanalyzing and negative self talk or self criticism. When we go for a walk outside three thing happen; endorphins are released to create greater joy, we’re distracted from overthinking by the vast number of stimuli all around us, and the air and sunlight gives renewed energy. Exercise in a gym delivers some of this, but the sounds and sights of nature are incredible mood lifters. A fun exercise is to spend time noticing everything around you using your senses. Concentrate on an object like a leaf or a shell. Notice how it smells, the colours and patterns, and even the sound and taste! Try it and see if it helps you to feel calmer and more connected to the world around you.
