My bedroom faces the sun and I can sleep just fine even with the curtains wide open - it only becomes a problem when it's unnecessarily hot and it starts to burn you

I can never sleep during the day regardless of how tired I am. Maybe it's the mindset that I'm wasting the day or just the light/noise from outside but ugh, it's depressing
To be honest, it doesn't really matter when you get the sleep, as long as you get it. All-nighters are never good cause your brain needs to recharge after everyday to retain info and stuff.
That's why I never did all nighters when I had exams and even though I studied less, got better grades than people who did all nighters mwahaaha
