The increasingly indoor and digital lifestyle of the modern world is creating a potentially negative environment that may be leading to “sensory deficits” for children primarily through environmental deprivation and digital over-stimulation. The sedentary nature of indoor lifestyles lack natural movement, outdoor textures, and spatial challenges which are crucial for brain development. Too much screen time, on the other hand, can lead to sensory overload and stunted motor skills.
The Rise in Sensory Deficits
The rise in sensory deficits are caused by:
- Lack of Outdoor Play (Vestibular & Proprioceptive) leads to decreased physical free play affecting the development of balance, spatial awareness, and muscle strength. Children need climbing, running, and uneven terrain to regulate their sensory systems.
- Sedentary Lifestyles (Tactile & Visual) and the over-reliance on screens limit physical play with different textures (such as, dirt, grass, and water), and flattens our children’s visual perception, since screens do not require the eye to adjust to 3D depths.
- Digital Overload (Auditory & Visual) from fast-paced, bright lights, and noisy digital environments can lead to chronic nervous system arousal. Our children become over-stimulated and struggle to pay attention.
- Processed Diets (Gustatory & Olfactory) from highly processed foods are one-dimensional in taste and texture. This stunts the development of the oral (mouth) motor skills and olfactory (smell) senses required from a varied diet.
Recognising the Signs of Sensory Deficits
When a child’s sensory system is under-developed, we may observe the following responses in everyday settings at school or at home:
- Sensory Seeking: Constantly bumping into walls, crashing into furniture, craving loud volumes, or exhibiting an inability to sit still.
- Sensory Avoiding: Panic or extreme tantrums in noisy/bright environments, extreme sensitivity to certain clothing fabrics, or strong resistance to having hair washed.
- Motor & Emotional Challenges: Frequent clumsiness, poor fine motor skills (e.g., struggling to hold a pencil), delayed speech, and emotional outbursts due to sensory overload.
How to Manage Sensory Deficits
Introduce sensory experiences into your child’s routine to counter the limitations arising from our modern lifestyles:
- Heavy Work Activities that provide deep pressure to joints and muscles, such as pushing a heavy stroller, animal walks (bear crawling), or carrying groceries.
- Messy Play by setting up safe spaces for tactile exploration using sand, water, clay, or finger painting to desensitise touch receptors. Sensory bins are a great way to implement this.
- Vestibular Challenges from swinging, spinning, or hanging from monkey bars. These activities are critical for processing gravity and balance.
- Strict Screen Boundaries with screen-free zones and time limits to reduce auditory/visual over-stimulation and provide time for the nervous system to reset.
