Sleep and how it affects one’s desire to exercise is kind of the tip of the iceberg because if we’re not getting effective sleep . . . a good sleep . . . . then it affects all aspects of our life. Sleep is as fundamental as breathing or eating is to our health. And if you’re not getting good sleep you’re going to wake up in the morning feeling draggy, unmotivated and feeling like there are a lot of limits on what you can do cognitively you’re not going to be as sharp as you’d like and certainly if you feel this way the desire to go out and exercise in addition to work is going to be pretty limited and your motivation to push through discomfort that you need to really get effective exercise is going to be greatly diminished so sleep affects all aspects of our health, all aspects of our fitness. To make it even worse, generally when we’re tired and not getting enough sleep, our desire for all the foods that aren’t good for us is much higher. We like the rush of the comfort food, sugar rush and what not. Sleep is really important to your overall health.
