Relaxation
The word 'relax' is a verb, hence it is a doing word that infers taking some action in itself. Relaxation is not just something we are doing when not doing something else. Relaxation is its own specific action. Relaxation is the specific action we can take to relax the muscles in our body, lower our heart rate and calm our nerves.
Being relaxed is not just a posture. We might usually associate lying down or being seated with relaxation but there are many ways of lying down that cause tension in parts of the body and many loungers that are not ergonomically safe. We can be relaxed standing up just as much as we can be lying down or sitting.
