Meet a British boy who cannot sweat
The boy suffers from a rare genetic condition, which means he cannot sweat.
Fred was kept in intensive care for the first four days of his life. When he was ten months old, he suffered his first seizure.
When the boy is overheated he has convulsions. His parents have to ensure their son keeps cool by using fans, water sprays and ice packs.
The family always has the windows open and keep the heating off.
