Sensory overstimulation is a very common phenomenon that occurs in human beings as a result of excess information load on the different sensory systems active in our bodies such as auditory, visual, olfactory, tactile and kinesthetic. This is common especially in situations where there is too much noise, excessive visual stimuli, and strong odors and so on. Crowds are a common cause that induces sensory overload or overstimulation. Sensory overstimulation is very common in certain disorders like Autism Spectrum Disorders but it is a myth that it occurs only in individuals who are diagnosed with this disorder/ spectrum. Rather, many individuals who are not falling in the spectrum experience sensory overload although it is more prominent in people who have Autism Spectrum Disorder. Some symptoms of sensory overstimulation are: anxiety, uncertainty, confusion, emotional overwhelms, tearfulness, racing thoughts, behavioral rigidity, and irritability, physical discomforts such as palpitations, increased heat beat, breathlessness, sweating, and dilated pupils. This can be accompanied by other emotional, cognitive, behavioral and physical symptom too.

Sensory overstimulation or sensory overload happens more commonly in people who are introvert in nature, those who are sensitive to changes internal and external to them. External circumstances include changes in environmental cues and internal changes include bodily changes, physical issues, bodily concerns, emotional experience. When we look at the biological approaches and explanation to sensory overstimulation, it has been observed that the threshold of sensation is very low. The Reticular Activating System (RAS) in the midbrain gets stimulated very easily in people who get overstimulated. It is very common phenomenon in childhood and in young children. Since the brain and neurological development of children is still an ongoing process, children feel and express differently when they are overstimulated. Some symptoms can be crying, irritability, throwing tantrums, shutting their eyes, screaming and in fact even psychogenic fever. The feeling that the body and the mind is shutting down is a common symptom of overstimulation. However it is important for parents/ caregivers to notice their children if this behavior persists as this might call for a clinical scrutiny and proper management during such stressful times. Children can learn over time to manage these symptoms and adjust better as they develop. These experiences, in both adults and children, can create a fear conditioning of certain situations, people, places and times and these fears can be generalized to similar situations and environment as well.

There could be certain accompanying mental or medical conditions and vulnerabilities that aggravate or induce the phenomenon of sensory stimulation. In case of traumatic experiences which are unwanted in nature and impinge heavily on one’s senses. Certain mental health disorders like Post Traumatic Stress Disorder (PTSD), Autism Spectrum Disorder (ASD), Attention-Deficit Hyperactivity Disorder (ADHD), Mood disorders, Neuro-developmental issues etc. One common environmental problem that acts as a trigger in ASD is heat or high temperatures. Children with Autism get overwhelmed in high temperature.

Now after understanding the causes of overstimulation, it is important to understand how to help someone who is feeling overstimulated. It is important to understand firstly that when someone is showing these symptoms, that person most possibly lacks the ability to deal with the feeling of overstimulation on their own, even if they are an adult. Therefore we must all be aware of some basic ways to help someone who is overstimulated. Some of the most easy ways is to pay them attention and ask if they want to move around, wash their face, drink some water and to help them ground to reality. Overstimulation can lead to behavioral rigidity and even freezing in time due to sensory overload. It can prove helpful to use senses like touch, closing eyes, playing soft music, holding cold water bottles, splashing water onto face, neck, nape of the neck, hands and feet immensely in this situation. Although they might be small and appear to be insignificant, they actually go a long way in helping someone. When it comes to seeking professional treatment, it can be really helpful to seek a child specialist, clinical psychologist, counsellor, occupational therapist to help someone with sensory overload. The experience and real life case handling enables such service givers with efficiency in dealing and helping people who experience this phenomenon. There are also certain self help techniques which one can employ and utilize to understand and better deal with sensory overload. These are as follows:

Identifying Triggers: It is possible and commendable to try and track down the events which created a sensory overload in an individual. It could be some specific people, some kind of music, a particular odor or scent, or anything. Once that trigger has been identified, it can be actively avoided as much as possible. For children, parents can do the same and help children learn the triggers for them as they grow.

Sticking To A Routine: A daily routine or practice that would help people in general to ground them, get back to a more light-headed experience, and release the pent-up stress and excess energy that gets stored in the body. This will work differently for everyone but it is important to have a routine and stick to it as much as possible. Many children with neuro-developmental problems have this routine because it becomes difficult for them to manage a randomized lifestyle which can set off overwhelming experiences.

Practicing Mindfulness And Allied Calming Techniques: Mindfulness is the practice of thinking and feeling about the present moment; now; and this really helps us to focus on currently ongoing problems and stimulus. Although this isn’t easy to learn and use immediately as crisis arises; but with practice and spending the entire time mindfully, it can become a part of the neural memory and activate itself in case of certain overwhelming experiences. Deep breathing, stress relaxation techniques, meditation, Yoga and physical exercises are common ways to regulate the sensory system and keep it from getting overwhelmed.

To conclude, it is important that we understand how sensory system works in different people and that some people are sensitive and more easily feel or sense various stimuli in their environment. This is both a boon and a problem. Such people can become great observers, analysts and helpers as they feel and understand the pain of others. They can be considered at times as empaths as well. However, this can also have an adverse result as they come into contact with the harsh and competitive reality. This harshness can jade them easily and overwhelm them into developing various mental health concerns. As a part of the society we must hold space for sensitive people or people who are easily stimulated by their environment and make sure their abilities are utilized in a proper manner.
