    As a thread that connects, modifies, and moulds our perceptions and understanding of the world, touch develops in the complex fabric of human sensory experience. The impact of touch on human development as a sense extends far and wide, touching on many areas of our lives, including our thoughts, feelings, and relationships. Touch, whether it's the soft touch of a caregiver's hand or the rough texture of the earth, is an important sense that shapes our brain circuits and promotes overall development. In this blog post, we explore the importance of touch in sensory development, specifically looking at how it affects early life, emotional health, and interactions with others.

    What Is Touch?

    Did you know that there are four distinct senses involved in touch?

    • Touch (cutaneous sensation): To feel anything with your fingertips means to be able to detect the connection between two surfaces. There are touch receptors in the skin of a youngster. When there is pressure on the skin, the touch receptors pick it up and relay the signal to the brain's touch neurons.
    • Temperature: Unlike touch (pressure) receptors, a child's skin contains temperature receptors that function autonomously. The brain then receives data from temperature and pressure sensors. While infants are sensitive to temperature, they struggle to control their core body temperature.
    • Pain: A child's body also contains pain receptors that transmit signals to the brain. It is believed that a baby can feel pain as early as the third trimester of pregnancy when pain receptors are already activated.
    • Proprioception: This is being aware of one's own body's location and motion. A child's skin, muscles, and joints all work together to relay information about the child's body and limb positions to the brain.

    Sensory Development and Importance of Touch

    In the formative years of a person's life, sensory development—which includes the sense of touch—is paramount. One of the most fundamental ways people engage with and learn about their environment is via their sense of touch, often called the tactile sense. The significance of touch and its role in sensory development are as follows:

    Early Brain Development

    During the early years of life, the brain undergoes rapid development. Sensory experiences, including touch, contribute to forming neural connections and pathways. Positive touch experiences are essential for the healthy development of the brain's sensory processing areas.

    Bonding and Attachment

    Touch is fundamental for caregivers to establish a strong emotional bond with infants. Skin-to-skin contact, cuddling, and gentle touch release oxytocin, a hormone associated with bonding and attachment. This bonding is crucial for a child's emotional and social development.

    Stimulation of Nervous System

    The sense of touch provides crucial input to the nervous system. Different touch stimuli, such as pressure, temperature, and texture, stimulate nerve endings in the skin. This sensory input helps in the development of the nervous system and the integration of sensory information.

    Body Awareness

    Through touch, individuals develop a sense of their bodies and the space around them. This proprioceptive awareness is important for motor skills, coordination, and spatial orientation. Activities that involve touching and feeling different textures can enhance body awareness.

    Cognitive Development

    Touch experiences contribute to cognitive development by fostering curiosity and exploration. Infants and young children often use their hands and fingers to explore objects and surfaces, building cognitive skills and understanding of the physical world.

    Regulation of Emotions

    Touch can have a calming and soothing effect on individuals. A gentle touch activates the parasympathetic nervous system, promoting relaxation and stress reduction. This is particularly important for children in managing their emotions and developing self-regulation skills.

    Social Skills

    Positive touch experiences contribute to the development of social skills. For example, handshakes, hugs, and other forms of appropriate touch are integral to social interactions and communication. Learning appropriate touch boundaries is an important aspect of social development.

    Therapeutic Applications

    Touch is often used in therapeutic settings to address developmental challenges or sensory processing disorders. Occupational therapists, for example, may use tactile activities to help individuals improve sensory integration and motor skills.

    Formation of Relationships and Early Development

    Some eight weeks into a woman's pregnancy, her sense of touch begins to take shape. As the growing brain establishes a strong relationship with touch, the unborn child is exposed to myriad sensations through the mother's womb. Recent studies have shown that early tactile sensations help shape brain networks, promoting the development of important cognitive abilities.

    The vital connection between a parent and infant is the one where the importance of touch is most apparent. Numerous studies have demonstrated the many benefits of skin-to-skin contact for infants, including regulating physiological functions, promoting emotional attachment, and developing secure attachment styles. A child's emotional resilience and social competence are laid down in the first few years of life by the comforting touch of a carer, which is more than just a nice gesture.

    Cognitive Development and Tactile Learning

    Even as they move from infancy into early childhood, touch is an important part of a child's brain development. To develop sensory discrimination and refinement, tactile encounters are crucial since they provide a portal into the physical qualities of things. One of the most important ways children's brains develop is through exploratory play, which involves physically touching and experimenting with various forms, textures, and temperatures.

    Sensory bins and other tactile learning tools help students better understand abstract ideas in the classroom. In addition to honing fine motor skills, children's hands-on study of three-dimensional items enhances their comprehension of mathematical and spatial relationships. Incorporating tactile sensations into educational environments promotes a comprehensive learning method, acknowledging the interdependence between sensory experiences and cognitive growth.

    Managing Emotions and Promoting Well-Being

    As a means of both self-soothing and expressing one's emotions, touch is a potent regulator of emotional states. A complex web of receptors on the skin communicates with the autonomic nervous system; these factors impact our emotional health, stress hormone levels, and heart rate. A reassuring handshake or a loving embrace can alleviate tension, calm nerves, and make you feel safe.

    Tactile encounters are crucial for the development of emotional intelligence in young children. Physical gestures like holding hands, patting someone on the back, or embracing someone teach children to identify and communicate their feelings. Developing a deep knowledge of empathy and connection through tactile, emotional communication paves the way for good relationships in later years.

    Motor Skills and Sensory Integration

    The intricate process of sensory integration includes the tactile system, which is linked to other forms of perception. In sensory integration, the brain combines and makes meaning of data from several senses. This complex dance of sensory processing relies heavily on tactile input and visual, auditory, proprioceptive, and vestibular inputs.

    There is a strong correlation between tactile sensations and the development of motor abilities. Babies practice their fine and gross motor abilities by investigating their environment through reaching, grabbing, and interacting with things. A child's motor coordination, spatial awareness, and self-assurance in navigating the real world are all positively impacted by tactile, sensory-rich play.

    Disorders of Sensory Processing and Other Difficulties

    Although touch is essential to growing senses, some people may have trouble processing sensory information because of tactile sensitivity or SPD. Tactile defensiveness impacts daily functioning and social relationships, defined as a dislike of specific textures or an excessive sensitivity to touch. However, hypersensitivity to touch might cause an individual to seek out extreme sensory experiences, impacting their behaviour and focus.

    When helping someone with SPD, it is essential to be aware of and able to manage any tactile sensitivity. Tactile activities are a common part of occupational therapy for desensitisation or to give adequate sensory input, which helps people better control their reactions to touch and navigate their sensory environment.
