Many people find it difficult to process sensory information. Any of the senses, Sight, Hearing, Smell, Taste and Touch (external senses) can be hyper-(over) or hypo-(under) sensitive. Children actively seek out activities that provide sensory stimulus, these activities vary according to which sense is over- or under- sensitive

When faced with overwhelming sensory input a person can become stressed or anxious. This can lead to a meltdown and the possibility of other behaviours. When looking at someone’s sensory challenges it is always recommended to consult an Occupational Therapist.

Most of us process information without having to think about it or even be aware of it. We also have internal senses:

Vestibular - sense of balance and movement it tells us where our body is in relation to the ground.

Proprioception - sense of body awareness and position, telling us if we are moving, how fast and in what direction.

How to Help - Activities that can help include using swings, seesaws and roundabouts.
