As temperatures rise across the UK, many parents are asking the same question:
What happens if my child genuinely cannot cope with school during a heatwave?
For many children, hot weather is simply uncomfortable.
For some autistic, ADHD and other neurodivergent children, it can be far more significant.
The combination of heat, bright sunlight, sensory overload, disrupted routines, poor sleep and dehydration can make school feel overwhelming.
Why Heat Can Affect Neurodivergent Children Differently
Many neurodivergent children experience:
- Difficulties recognising thirst or overheating.
- Sensory sensitivities to heat, clothing, sunlight or humidity.
- Increased anxiety and dysregulation.
- More frequent meltdowns or shutdowns.
- Sleep disruption, leading to exhaustion the following day.
- Challenges communicating when they are becoming physically distressed.
Some children may continue wearing coats, jackets or preferred clothing despite hot weather because of sensory needs.
Others may not recognise they are becoming overheated until they reach crisis point.
This can create additional challenges in school environments where classrooms, playgrounds and dining halls may become extremely warm.
Should Parents Keep Their Child Off School?
There is no simple yes or no answer.
In most cases, schools should first consider whether reasonable adjustments can help a child safely access education during periods of extreme heat.
Examples may include:
- Access to cooler rooms or shaded areas.
- Relaxed uniform requirements.
- Additional drink breaks.
- Access to fans or cooling equipment.
- Indoor alternatives during break and lunch.
- Flexibility around activities that may increase heat exposure.
- Earlier identification of signs of distress.
The focus should be on supporting attendance wherever possible while ensuring the child’s health, safety and wellbeing are protected.
What Schools Should Understand
A child who appears “fine” may still be struggling.
Heat can increase:
- Anxiety.
- Sensory overwhelm.
- Irritability.
- Fatigue.
- School avoidance.
- Emotional dysregulation.
Behaviour that appears oppositional may actually be a sign that the child’s nervous system is overwhelmed.
This is particularly important for autistic children, children with ADHD, PDA profiles, sensory processing difficulties and other SEND needs.
Practical Tips for Parents
- Encourage regular drinks throughout the day.
- Consider cooling towels or sensory-friendly cooling products.
- Prioritise sleep where possible.
- Communicate concerns with school early.
- Monitor for headaches, dizziness, unusual fatigue or increased distress.
- Explain any sensory barriers to changing clothing or removing jackets.
The Most Important Thing
Every child is different.
What works for one child may not work for another.
The goal should never be attendance at all costs.
The goal should be helping children remain safe, regulated and able to learn.
If heat is significantly affecting your child’s ability to access education, speak to the school as early as possible and work together to identify reasonable adjustments that may help.

Subject: Urgent Concerns Regarding Heatwave and My Child’s SEND Needs
Dear [Headteacher/SENCO],
I am writing regarding the current high temperatures and the impact they are having on my child, [Child’s Name].
As a child with [Autism / ADHD / Sensory Processing Difficulties / PDA / Other SEND], [Child’s Name] experiences significant difficulties that can be made worse by extreme heat. These include [sensory sensitivities, anxiety, emotional dysregulation, difficulties recognising thirst, difficulties recognising when they are overheating, sleep disruption, communication difficulties, etc.].
I am increasingly concerned that the current weather conditions may be affecting their ability to safely access education and remain regulated throughout the school day.
In particular, I have observed:
• [Insert examples]

I would therefore like to request that the school considers reasonable adjustments during this period of hot weather, including where appropriate:
• Flexibility around uniform requirements.
• Access to cooler indoor spaces.
• Additional water and drink breaks.
• Opportunities to avoid direct sunlight where possible.
• Access to sensory or regulation breaks if required.
• Consideration of indoor alternatives during particularly hot periods.
I appreciate that schools are facing challenges during the heatwave, however I believe it is important that [Child’s Name]’s SEND needs and welfare are taken into account when considering how they can safely access education.
I would be grateful if we could discuss any additional support or adjustments that may help during this period.
Thank you for your understanding and support.
