How to check for collisions in Update method (i.e. not just with OnCollisionEnter)?

Or if there’s any other way to check for collisions on an ongoing basis, I’m all ears. Basically, I want the character’s speed value to be continually set to a certain value whenever they’re touching a certain object - WHENEVER, not just when they first hit it. I do successfully have it working for when they first hit it, using OnCollisionEnter.

OnCollisionStay.
