Is there a swimsuit that lets you know when you have been in the sun too long?

Yes, there are innovative swimsuits designed with UV-sensitive materials that change color when exposed to harmful levels of ultraviolet (UV) radiation. These swimsuits help wearers monitor their sun exposure and encourage timely reapplication of sunscreen. Some models even integrate technology that connects to mobile apps for more precise tracking of sun exposure. This feature aims to promote skin safety and prevent sunburns.
