In fact, sleep is something we can't do without. It's among my 2023 resolutions to always make sure I sleep before 11PM. With this, I can manage to have at least 5hours sleep becauseI wake up at 4Am. The 8hours seems to be too much for me. Although I'll always try to fix a nap in day time.
As you said you usually stay awake up to 1AM, then I don't think you sleep that much in a single day.
