Travelling through airports with an invisible illness can be difficult, as it may not be obvious to others that you need extra time or assistance. The experience can be stressful and anxious for some, and it may be hard to explain your hidden symptoms. This is why several airports in the UK have implemented a scheme, so that those with invisible illnesses can order a sunflower lanyard to wear through the airport. These lanyards make the wearer more visible so that they can travel independently, but access help quickly if needed. Some supermarkets are also trialing this scheme.
