Here is the science.
Most snooze buttons are set to last around 9 minutes. That amount of time isn’t enough for you to complete a full sleep cycle (75-90min), so your alarm ends up jolting you back to wakefulness while you’re still transitioning between sleep stages. Research shows that your memory, judgement, and reaction time are all affected, and it can take up to 4 hours to go away. (unless you take a cold shower!)
I admit it. I used to be a snooze button addict. 😩
Every morning my alarm clock would go off and I would hit that button at least 2-3 times. And I always feel worn out, still tired, confused and start worrying about bad night sleep. It feels like you have to rush through your morning in the search of those lost minutes the snooze button stole from you.

The sense of achievement itself 😁

The downward spiral.
