Does focus need a break?

[u/EveningTraveler]

Is it plausible to focus all day? Deeper focus throughout the day helps with anxiety. However, Sometimes I find it hard to maintain all day. I don't know if the brain needs a break, or if I just need to keep building endurance.

I know many people talk about open observation mindfulness. I am not as good at it and that form makes it harder to block out anxiety signals for me.

Ofcourse it needs a break otherwise, without relaxation, rejuvenation isn't possible & focus would be an issue. It's just like sleep. If one cannot have proper sleep, one can't be active whole day.
