Thermodysregulation in Autism means it is hard to keep body temperature normal. People may feel too hot or too cold.
Many autistic people have trouble noticing and handling temperature changes. Their bodies sense things differently. This can make them sweat too much or feel bad in some places.
They might react strongly to having a fever. Knowing about these problems helps caregivers and families. They can better help autistic people and meet their special needs.
Key Takeaways
- Thermodysregulation means autistic people can’t keep their body temperature steady. They might feel too hot or too cold.
- Brain signals, hormones like oxytocin, and sensing body changes can cause these problems.
- Signs are sweating a lot, not feeling cold, acting differently, and odd reactions to fever.
- Caregivers and schools can help by looking for these signs. They can use cooling or warming tools. They should make safe and comfy spaces.
- Planning with clothes, drinking water, and quiet breaks helps autistic people stay healthy. It also helps them enjoy daily life.
Thermodysregulation in Autism
Thermodysregulation in Autism happens when the body cannot keep its temperature steady. Many autistic people feel temperature changes in a different way than neurotypical people.
Some feel hot or cold much more than others do. Others may not notice temperature changes at all. This is because their brains sense things differently.
Autistic people may:
- Feel heat or cold much stronger than others.
- Need bigger temperature changes to notice them.
- Do things like flap hands or rock when uncomfortable.
- Change how they talk or act when they feel bad.
- Show signs of dehydration or overheating that are not expected.
Things like humidity or air pressure can make these feelings worse. Caregivers and teachers often see more anxiety or irritability in autistic people when the temperature changes. These reactions do not look the same as in neurotypical people.
Causes and Mechanisms
Thermodysregulation in Autism has many causes. The brain and body work together to control temperature, but this system works differently in autistic people.
- Sensory Processing Differences
- Many autistic people have trouble with interoception, which is the sense that tells the brain about the body’s inside, like temperature or hunger.
- Poor interoceptive awareness makes it hard to notice when the body is too hot or too cold.
- This can cause problems like not wearing a coat when it is cold or not drinking water when it is hot.
- These challenges make it harder to keep the body safe.
- Neurological Factors The brain uses signals to control temperature. Lower brain temperatures link to more excitatory activity, which connects to autistic traits. When body temperature goes up, like during a fever, some children with autism act differently. This shows that temperature can change how the brain works in autism. The hypothalamus helps control body temperature. It reacts to small changes and releases hormones like oxytocin, which also affect social behavior and stress.
- Hormonal Influences
- Oxytocin is a hormone that helps with temperature, energy, and social behavior.
- Children with autism often have less oxytocin than neurotypical children.
- Oxytocin affects how the body feels and reacts to temperature.
- Animal studies show low oxytocin causes problems with staying warm and social behaviors.
- Early oxytocin treatment in animals can help with temperature and social skills.
- Interoception and Health Risks Interoceptive problems mean autistic people may not notice when they are too hot or too cold. This makes serious health problems, like heat stroke or frostbite, more likely. The insula, a part of the brain important for interoception, works differently in autism. This makes it harder for autistic people to react to changes in body temperature.
Caregivers should look for signs of discomfort, like changes in behavior or more stimming, because these may mean temperature problems even if the person does not say they feel hot or cold.
Thermodysregulation in Autism is caused by many things in the brain, hormones, and sensory systems. Knowing these causes helps families and professionals keep autistic people safe and comfortable.
Symptoms
Heat Sensitivity
Many autistic people are sensitive to heat. Their bodies may not cool down well. This can make them feel bad or even get sick.
Some signs to look for are:
- Sweating a lot when it is warm
- Skin turning red or pale
- Breathing changes when too hot
- Trouble sleeping because of heat
People with autism may not keep their body temperature steady. Sensory processing problems can make them feel heat more strongly.
This makes it hard to react the right way. Sometimes, they do not notice heat or react too late. Caregivers should watch for signs of being too hot. Some autistic people cannot say when they feel bad.
Cold Sensitivity
Cold sensitivity is not the same as heat sensitivity. Many autistic teens and adults do not feel cold as much. They may not notice when they get cold. This can make them more likely to get hypothermia. Some signs are:
- Not feeling cool temperatures well
- Not noticing cool, but still feeling cold pain
- Less able to sense temperature, which can affect thinking
- Different ways of feeling cold that match how severe symptoms are
Studies do not show if kids or adults have more cold sensitivity. Both can have trouble knowing when it is cold. This can make them stay in cold places too long. These sensory problems make it hard to dress right or get warm.
Fever Response
Fever can cause unusual reactions in autism. Some autistic people act better when they have a fever. This is called the “fever effect.”
Research shows about 83% of autistic people are more social and alert with a fever. These changes go away when the fever ends. One big study found 17% of autistic kids improved in thinking, talking, and social skills during fever.
Kids who get better with fever often have lower non-verbal skills and more repetitive actions. Fever may help the brain work better and raise oxytocin.
Oxytocin is important for social behavior. But most autistic kids become less social and more upset with fever. These odd fever reactions are linked to immune system differences.
They can also raise health risks. Taking care of fever in autism needs extra care. Some treatments may change how the immune system grows.
Sensory and Behavioral Effects
Thermodysregulation in Autism changes how people feel and act. Many autistic people cannot feel temperature on their skin or inside their body well. This makes it easier to get too hot, too cold, or burned. Behavior changes include:
- Not knowing when they are too hot or cold
- Not drinking water or wearing warm clothes when needed
- Trouble with self-control, eating, bathroom use, and feelings
Too much heat or cold can make them tired, anxious, or unable to focus. These problems can make daily life and moving around harder.
They may pick clothes that feel good instead of what is right for the weather. Caregivers should help by checking temperature, giving sensory-friendly options, and helping them talk about feeling bad.
Using layers of clothes and cooling or heating tools can help. Knowing about sensory and body differences is important to help autistic people.
Risks
Medical Complications
Thermodysregulation in autism can cause many health problems. Autistic people have more risks if their bodies cannot keep temperature normal. Some problems that can happen are:
- Seizures can start with fever, mostly in people with epilepsy before.
- Fever can make people confused or unable to focus for a short time.
- Being sick can make them more irritable, sensitive, and have trouble sleeping.
- They can get infections more easily because their immune system is different.
- The brain can get inflamed, and this can make symptoms worse when temperature changes.
A study from South Korea showed autistic people sometimes need emergency help for heat. They may go to the hospital if their body cannot control temperature.
Taking medicine for mental health and having social problems can make these risks higher. Doctors and nurses should watch closely and help to keep them safe.
Families should check body temperature and look for quick changes in behavior when someone is sick.
Sensory Overload
Sensory overload often happens when autistic people have trouble with temperature changes. Many cannot feel their own body signals, like being thirsty or warm.
This makes it hard to know when they are too hot or need water. Problems with interoception can upset the body’s balance and make self-care hard.
- Feeling things more strongly can make heat, humidity, or sweating feel too much.
- Sensory overload can make people irritable, anxious, or shut down.
- It is harder to control feelings when overheating makes frustration worse.
Autistic people may not notice early signs of heat stress. This makes thermodysregulation and health problems more likely.
When to Seek Help
Some signs show when someone needs a doctor for temperature problems in autism:
- Seizures or trouble breathing
- Symptoms that do not get better at home
- Signs of dehydration, like headache, tiredness, dizziness, or confusion
- Quick changes in behavior, like more irritability or trouble focusing
Families should have a plan for emergencies and talk to doctors to handle fever and stop serious problems. Going to the hospital may be needed if things get worse or do not get better.
Management
Home Strategies
Families can do many things to help with thermodysregulation in autism at home. Keeping rooms cool is helpful. Use fans or air conditioning and close curtains when it is hot.
Some families make special cool spots in the house. Wearing loose, light clothes and using cooling items like neck wraps or vests can help. It is important to drink water often. Caregivers give cool drinks and snacks like watermelon. Plan activities when it is cooler outside.
Playing with water can help lower body temperature. Using cool wet cloths or misting fans can make people feel better. Everyone is different, so families should ask what feels good and change plans if needed.
School and Work Tips
Schools and jobs can help autistic people by making small changes. Teachers and bosses can let people wear comfy clothes. They can give fans or let people take breaks in cool places.
Signs that remind people to drink water or use cooling tools are helpful. Plan outdoor time when it is not too hot and make shady spots. Staff should look for signs someone feels bad and help them talk about temperature needs.
Clothing and Hydration
Picking the right clothes and drinking enough water are very important for thermodysregulation in autism. Wearing layers helps people change clothes if they get too hot or cold.
Light, airy fabrics help keep the body cool. Some people use special cooling or heating vests or pads. Remind people to drink water and eat snacks that have water in them. Pictures or timers can help people remember these steps.
Caregiver Support
Caregivers are very important for helping autistic people with temperature control. They can teach ways to calm down, like deep breathing or using pictures.
Caregivers should watch and change plans to fit each person. Making a calm space, giving comfort items, and keeping routines the same can lower stress.
It is good to work with doctors to make a plan for fevers. Support groups and expert advice give caregivers more help and ideas.
Being patient and watching closely helps caregivers find the best ways to help each person with thermodysregulation in autism.
Daily Life Impact
Social Participation
Thermodysregulation changes how autistic people join social events. Many feel bad in places that are too hot or cold. They might skip group activities outside or in busy rooms.
Some kids do not play outside in summer or winter because their bodies cannot handle temperature changes. Others may leave birthday parties early if the room feels stuffy or cold.
Friends and family sometimes do not get why they make these choices. This can make autistic people feel left out or lonely. It is harder to join in when others do not see the hidden problems with temperature discomfort.
Activity Barriers
Everyday things can be hard for autistic people with thermodysregulation. Simple tasks like walking to school, playing sports, or shopping can cause stress.
Some do not want to wear clothes for the weather because some fabrics feel bad. Others may not notice when they get too hot or cold, which can be risky.
Teachers and coaches may not know why a child skips gym class or recess. These problems can limit learning, exercise, and fun. Families often need to plan extra breaks or bring special things like cooling towels or water bottles.
Using visual schedules and reminders helps autistic people get ready for temperature changes in daily routines.
Community Awareness
Community awareness is important for helping autistic people with thermodysregulation. Many people do not know that autistic people often have trouble with interoception, which is the sense that tells the brain about body needs like temperature, hunger, or thirst.
Without good interoceptive awareness, it is hard to notice feeling bad or ask for help. When communities learn about these problems, they can give better support.
Schools, jobs, and public places can offer quiet rooms, let people wear comfy clothes, and give water. More awareness brings more kindness and real help, making it easier for autistic people to stay safe and comfortable every day.
Thermodysregulation in Autism can change how someone feels every day. It can also affect their health. Families and caregivers should watch for signs early.
They need to check often and talk openly with autistic people. People in the community can learn more about this. They can help by making places safer for everyone.
People can ask for changes at school or work to help. When people learn about thermodysregulation in Autism, they can give better care and support.
