WATERLOO (KWWL) -- It's the biggest meal of the year: Thanksgiving dinner.
But the traditional holiday meal may leave you a little drowsy.
Although turkey has been blamed for after dinner naps because of L-tryroptohan, studies find our sleepiness is actually caused by other factors.
For example, when you over-eat it, blood is directed away from other organ systems during digestion, including your nervous system which could cause the need to take a snooze.
Also, alcohol is a depressant and can cause anyone to feel sleepy if they drink too much.
