Do We Really Wake up in a Bad Mood 300 Days a Year?

I came across a study recently that said that we wake up in a bad mood 300 days a year! That's basically five or six days a week.

What puts us in that bad mood? According to the study, it's either waking up cold, waking up too hot, noises or a bad/strange dream.

I guess I can attest to waking up in a bad mood if I'm awakened in the middle of the night.

For me personally, if I can't get to sleep at night, I definitely wake up in a grumpy mood. My alarm goes off at 2:15 a.m., and every minute I can't get to sleep is one minute less of sleep. And I need my sleep.

But 300 days a year waking up in a bad mood? Seems excessive.
