I don't have time to research why I become sleepy when I go to the countryside. Now I'm curious about: *Why do people turn darker when they go to rural areas?* I see everyone discussing it, but I don't know why—*as soon as I step into the countryside*, even if I don't intentionally sunbathe much, after staying for a while, my face becomes *dull and faded*, my skin condition worsens, and I get darker and darker.
