Chocolate has an odd effect on our brains.
The scent of chocolate induces theta brain waves, which result in relaxation. In fact, research done at Hasselt University throughout Belgium found that when the aroma of chocolate was dispersed in bookstores, book sales increased, particularly for romantic novels. Yes, relaxation! Chocolate also includes tryptophan, which the brain needs to make serotonin, a hormone that induces feelings of well-being. So eating chocolate actually makes you happier!
