We've all been there – you eventually make it home after a big night out, snuggle into the covers and prepare yourself for the glorious lie-in that awaits, only to be rudely awoken by some kind of drunken mystic force at 8am.
Maybe it's our bodies trying to get back at us? Or perhaps it's the universe trying to turn us into functional human beings? Either way, it's annoying AF and it's time to get to the bottom of it.
Just like all out little bodily quirks, science has a big role to play. Speaking about the phenomenon, As Dr. Aaron White, a senior scientific advisor to the director of the National Institute on Alcohol Abuse and Alcoholism, explained to Buzzfeed:
"Alcohol tricks you into thinking you're sleeping better because you pass out a little faster but it's actually very disrupting and prevents you from getting a restful, deep sleep."
So, not only does alcohol make you lose all inhibitions and convince you that you're more than able to flirt with the hunky man at the bar, it also completely messes with your sleeping pattern – Great!
What's more, once the alcohol wears off in the middle of the night, our bodies enter into REM sleep, making it much easier to wake up.
The only way to prevent this is to take it easy on the G&Ts and stop drinking a little earlier in the night.
You win some, you lose some.
