Autism Coping with illness: Why even mild symptoms can feel overwhelming

Autism Coping with illness: Why even mild symptoms can feel overwhelming Catching a cold or the flu is never enjoyable, but for autistic people the experience can feel far more intense.

Autism affects sensory processing, communication and daily routines, which means even mild illnesses can lead to physical and emotional strain that others may not fully understand. As awareness grows, so does the opportunity to shape care that genuinely meets autistic needs and helps create healthier experiences in the future.

Every autistic person is different, yet many share patterns in how they experience discomfort, pain or sudden changes in their body. When illness strikes, these factors can add extra layers of difficulty and can also influence how someone seeks support.

Heightened sensory sensitivities

Many autistic people have increased sensitivity to sensory input. When the body is fighting illness, sensations often become stronger and harder to manage meaning Autism Coping with illness can include:

• stronger awareness of aches and pains

• increased sensitivity to temperature changes

• discomfort from blocked ears or sinus pressure

• irritation from certain textures, smells or clothing when feeling unwell

These experiences can quickly build toward sensory overload. What might feel like mild discomfort for a non autistic person can feel extreme for someone who processes sensory signals differently.

Difficulty describing symptoms

Some autistic people find it harder to describe what they are feeling or to recognise the source of discomfort. This can make explaining symptoms such as headaches, dizziness, nausea or chest and sinus pressure far more challenging. If the person cannot easily put their symptoms into words or connect them to illness, frustration, fear or confusion can rise very quickly.

These communication differences are not a lack of awareness; they reflect unique ways of sensing and interpreting internal signals. Understanding this helps create better communication between autistic people, families and healthcare professionals.

Changes to routines and emotional regulation

Illness often disrupts daily routines. For autistic people, routines provide stability and predictability. When symptoms interrupt sleep patterns, eating habits or scheduled activities, stress levels can climb. These routine changes can also make emotional regulation more difficult, especially when combined with physical discomfort.

Looking ahead, building flexible routines that can adapt to illness will help reduce stress and provide reassurance when life becomes less predictable.

Lower tolerance for sensory demands

Simple things that are usually manageable can become much harder when unwell, including bright lights, noise, movement and touch. Being physically ill reduces the energy available for coping with sensory triggers. This can lead to overload, shutdowns or withdrawal if the environment becomes too demanding.

The need for extra rest and quiet

Autistic people may need more time in quiet, low sensory surroundings when sick to support both body and mind. Rest is vital, yet overstimulation can slow recovery or make illness feel more draining. Creating restorative spaces is an important part of neuroinclusive wellbeing.

Practical strategies that make illness easier to cope with

Whether supporting yourself or someone else, a few thoughtful adjustments can make a significant difference:

• provide a calm, predictable environment

• reduce sensory demands whenever possible

• offer clear and simple explanations about symptoms and recovery

• allow extra rest without pressure

• check in gently rather than expecting long conversations

• use comfort items such as blankets, weighted supports or soft lighting

• support communication with choices, yes or no questions or written options

Creating a personalised health toolkit can also help. This might include communication preferences, sensory needs or past experiences with treatments. Sharing this ahead of appointments makes healthcare more accessible and less stressful.

Listening to lived experience

Trevor Sherwood, Creator of LilyAnne’s Wellbeing, often shares the importance of understanding how autistic people interpret illness:

“When an autistic person becomes ill, every sensation can be amplified. The challenge is not only the illness but the added sensory and emotional load that comes with it. Creating calm, predictable support can make recovery much easier.”

This insight reflects a wider shift toward neuroinclusive care that respects the individual rather than expecting them to adjust to rigid systems.

Looking forward

Flu and colds are a normal part of life, but for autistic people they can be more intense and difficult to manage. Greater understanding helps create kinder, more supportive environments at home, at work and within communities. By listening to autistic voices and adapting care, we move toward a future where illness feels less overwhelming and support feels easier to access.
