How do you cope with the afternoon anxiety bump?

Every day, I’m always motivated and in general feeling good and happy, but right after lunch, I feel my anxiety taking over, and it feels like feeling it taking over actually increases it, but I don’t know how to deal with it.

I feel like it’s a kind of “sunset anxiety”, because I start to see the beginning of the end of the day, maybe an overwhelming self-demand regarding productivity, idk…
