Body language
The body language of the head should be considered in conjunction with that of the neck. In terms of general posture, the head should be positioned in a manner which feels natural. Body language conveyed by the head and neck involves various ranges of movement. However, it is important to note that the positioning of the head should not cause the neck to be stretched or compressed for too long a period of time without relief. If the neck is strained in this manner, it may inhibit the ability to use it to convey body language messages effectively. In addition, some researchers and health practitioners have found that there is a relationship between prolonged poor posture of the head and neck, and negative mental states. As such, body language which involves the head and neck should not cause strain and seek to be as natural as possible. As with all forms of body language, it is useful to understand as many other connected factors as possible in order to accurately identify the meaning.
