Take frequent walks. Regular walking is beneficial for body, mind and spirit.
Walk at whatever pace suits you and check in with the physical sensations of walking: the feel of your feet on the path, the flex of your legs and arms. Without effort, relax your upper body. Notice your breathing.
When you have established a comfortable rhythm start to become more aware of your surroundings. Experience where you are and what is in the vicinity – whether you are in the country or the city is not important.
