Powering a heater with pico

I have small 8w 5v heater films for a project. I vaguely recall someone saying powering things on the pico like this would damage the pico. My project would need to power this heater based on an attached temperature sensor, while also powering a 5v LED on a timer. Should I be concerned about the power draw damaging the pico.

You need a circuit that can control that voltage/current. The main components to use is a Relay or MOSFET.
