Not sleeping in the afternoon- cold exposure worked the opposite way

What the hell do you do for staying awake through the day or rather to not sleep in the afternoon.

I woke up at 7, viewed sunlight within 15-20 mins, had caffeine after about 1.5hrs, then worked out for 15min (swim, also it was a rest day), after that cycled thrice between sauna and a chiller shower (it pumps refrigerated water, good enough to make me scream in a public gym), came home had a smoothie, did some desk work for 2 hours and then slept like a baby for 3 hours, now my sleep for the night is ruined 😭. I literally wanna cry.

What’s your stack/process to not sleep in the afternoon?
