How easy is it to see when someone is truly relaxed and happy? Apart from the calm stillness of subtle pleasure, activity is the key to identifying these emotions. It is simply not possible to enjoy something, or even to be totally engaged by something, and not express it in body movement.

Notice the outlets for energy: movement of arms and head in particular, but also leg movement, so-called happy feet.

Smiling is almost always a feature  – from the faintest corner-of-the-mouth twitch, to a broad beaming smile that creases the eyes.

The eyes also tend to be larger when someone is relaxed and happy ('wide-eyed') as they take in the maximum of visual information. In moments of pleasure we sometimes see a rapid widening, the 'eye pop'.

Positive emotions are also associated with relaxed muscles in body and in facial muscles, particularly in and around the mouth.

We often see a confident non-defensive posture, an 'opening up' of the body, torso exposed, arms relaxed by the side, facing the person in conversation full on.
