Congenital insensitivity to pain with anhidrosis

Congenital insensitivity to pain with anhidrosis is a disease that means people born with it cannot feel pain and do not sweat. This can be very dangerous because pain is a signal that tells you when you're hurting yourself or when something is wrong with your body. If we don't feel pain, we might not know when to stop doing something that is causing damage to our body.

People with this disease also do not sweat, which can cause their body to overheat. Sweat is a way for our body to cool down when we get too hot, so without that ability, people with this disease can get very sick and even die if they get too hot.

It's important for people with this disease to be very careful and aware of their body's limits. They should be careful not to do things that could hurt them and they should also take steps to stay cool, like staying in shade or using fans. It's also important for them to see a doctor regularly to make sure they stay healthy.
