Sleep is really a far more critical piece of maintaining vitality than we often give it credit for. Since we have so much on our plate to do every day, we often put sleep off into a category of “pleasure and luxury”, but in reality, lack of adequate sleep causes everything from weight gain, immune system dysfunction, to memory loss with a significantly increased risk of developing dementia.
In other words, sleep is in no way a Luxury. It is a total necessity for each and every one of us.
With this said, many of us consume a decent amount of caffeine, starting with coffee or tea in the morning, soda or tea following our coffee, and end the day with some chocolate dessert. ALL of these foods / drinks contain caffeine.
