I read your article “Why I do not use social media”, however, many times I know it’s very bad to keep using my smartphone, checking TikTok and other social media software, but I just can’t stop it. Even that exposure to sunlight was already helping me, as it helped regulate my sleep cycle (you can find scientific findings on what our skin synthesises with sunlight). I could not fix my inclination to procrastinate without changing other parts of my life: unthinking procrastination while keeping everything else constant would be a fool’s errand.
