This is a bizzare take. The work nap prevalent in East Asia is taken post lunch. People feel dozey after a meal and a short rest is physically and mentally refreshing. Calling it performative is ridiculous.
I never claimed that every nap taken in East Asia was performative, just that performative naps are prevalent there. For instance much ink has been spilled about "inemuri" in Japan and all the related social dynamics that drive it.
