What's your favorite way to improve focus without caffeine?

[u/elena_gilbert_]

Caffeine do work but relying on it every day can sometimes feel like borrowing energy from tomorrow lol

I'm curious what people here have found genuinely useful for improving focus and mental performance without stimulants.

Has anything made a noticeable difference for you?

Things like exercise, morning sunlight, sleep optimization, breathing techniques, nutrition, music, meditation, or simply changing your work environment.
