Acomplete definition of body image includes how intelligent one believes him or herself to be.

It is essential that we properly define ourselves and should have a clear image of our body image. It should be rooted within us to be properly identified and respected for who we want to be. However, I don't think that the intellect of a person should affect that and that it should be clear that body image has very less or nothing to do with intelligence.

that statement is false Level of Intellegence has nothing to do with it, All that matters is how you perceive yourself. If you value a aesthetic body, then you should go on a diet and make an effort for it. If you don't , then you simply just need to not care about other people think. Either way, you just need to be confident in yourself

Yes she should but is this a question?

Because without physical activity, the body has extra "energy" if you will, and so when it is time for bed you are not tired, so you end up staying up all night. also there is probably an effect on your internal clock, which messes with your melatonin production which goes hand in hand with your sleep cycle
