People do get just as tanned / burnt when moving. The people on the beach probably spent more time in the sun.

People definitely get tanned while walking or running.

But more body coverage and overall even tan when ur laying down. You’ll notice people get more tanned shoulders and arms when just walking around.

People get sunburned walking around or working in the sun.

It's just likely that moving around doesn't present any single part of your body to the sun constantly, and you probably move into shade intermittently.

Being by water intensifies or reflects really, more light on people nearby.
