Everyone deals with stress some of the time. One of the most popular times? The holidays. Gifts to buy, meals to cook, family drama to dredge up again. It can be a lot to handle. Most of us probably know the telltale symptoms of stress: muscle tension, headaches, sleeplessness, irritability. But it has some more surprising and insidious effects, too.For example, did you know that there's a scientific link between stress and acne?

There are many myths surrounding the essential amino acid tryptophan and Thanksgiving dinner. When tryptophan is taken on its own at certain doses on an empty stomach, it can make you sleepy.

When you overeat, your body diverts blood to your stomach and the rest of the digestive system to handle the overload. Most American consumes as many or more calories during Thanksgiving dinner than in a single normal day. In addition, there are lower levels of tryptophan in turkey than in chicken.
