Interoception detects responses that guide regulation, including hunger, heart rate, respiration and elimination 😊 The Interoceptive stimulation is detected through nerve endings lining the respiratory and digestive mucous membranes 🤓 To determine the way an individual sees themselves, interoception uses their vestibular as well as proprioceptive senses 👍 Interoception that is well-modulated helps an individual to detect vestibular and proprioceptive sensations normally. If a person experiences a pounding sensation in their heart, it’s not indicative of trauma. The stimulation will not be craved. This is also true of hunger, thirst, and the sensations that you need to urinate. 
This sense interprets data sent to the body via the skin. There are touch receptors on the skin that sense pressure, heat, and pain. The development of this sense may look like a messy room or situations where a child has strewn through toys or different textures such as sand or water and has made a ‘mess’. Children react to touch very rapidly, whether positively or negatively. Tactile Defensiveness Disorder and Hypersensitivity Disorder affect children’s touch reactions. 
SPD Support offers an online questionnaire that will help determine if your child suffers from SPD. An occupational therapist may be able to help a child with scattered problems. A consultation with an occupational therapy professional is strongly recommended if a child faces multiple problems in one or more of these categories. It is important to note that sensory processing concerns do not spontaneously arise—there is a developmental history to them. A baby who is hard to soothe, a child who crawls slowly or never crawls well, or a toddler who refuses to touch the food tray. SPD can be identified in all of these situations. Prematurity and foetal alcohol syndrome are all indicators of SPD. Kyle T. From Jundiai (Brazil), October 4, 2020 
Chlss.org Further insight is provided by this article. This sense of touch helps to understand how our bodies respond to sensory stimuli. It helps us locate where we are feeling physical sensation within our body and to determine between “safe” and “dangerous” touch, as in the common example of the child touching the stove. Someone who struggles with tactile processing may interpret light touch as dangerous or harmful, even though there are no dangers. The person might become more anxious about this sensation and react with flight or fight responses to light touch on their shoulder.
