Autistic burnout is when someone who has autism feels really tired and overwhelmed with their autism. It's like when you play really hard all day and before bedtime you feel so tired you just want to go to bed and sleep. Autistic burnout can happen because people with autism use a lot of energy to try to fit in, communicate and understand the world around them.
Think of it like an extra battery in their brain being used, and when that battery runs out, they need to rest. This can make it hard for them to do everyday things like going to school or hanging out with friends. It can also make them feel stressed or sad.
To help someone with autistic burnout, they may need more rest and extra support from their family and friends. They may also need to find ways to reduce stress and take breaks when they need them. So if you know someone with autism who is feeling really tired and overwhelmed, it's important to be kind and understanding and try to make things easier for them.
