I read this article, which wrote about the strong relationship between sleep pattern and mental health. It is surprising to know that jet lag can actually get people into mania and depression. A healthy sleep schedule can give you a good mood.

Should more medical practitioners use light therapy to fix mood disorders?

I’m not sure what is light therapy, but to fix mood disorders, you have to make people sleep well. Which means get into sleep quickly and at the right time, and wake up and get sunlight at the right time. To do that, the artificial light should be blocked through night, but sunlight needs to get in at the morning, which is quite challenging. The sleep schedule should be fixed everyday at the right time(10:30-6:30). It is true for me that when I don’t get enough sleep in a particular day, I wake up and get angry or sad for no reason at all. Also I had difficulty go to sleep if the artificial light is not fully blocked. But I personally don’t feel the effect of sunlight, because if it is raining and the sky is dark in the morning, I don’t feel any difference.

I would say the mood issues can all be fixed if the person can sleep well.

— Dr. Friedman supposes that the reasons more depressed patients don’t receive chronotherapy are that it isn’t taught in medical school, and that sleep deprivation or light can’t be patented so there is little financial incentive to invest in this treatment or research. Do you agree? Why or why not?

My answer: I don’t think so. I think the chronotherapy is not yet being add to the medication is just because there haven’t been anyone bothered enough to add that new system or method to carry out the chronotherapy. Because there could be a lot of difficulty in establish a new thing. So I think if someone figured out how to do it, then of cause he can get patent in someway. Or maybe someone in the world already did but failed or failed to spread. Not everything have to be taught in school, it can also be taught in the working place.

— Should more medical schools teach chronobiology? Should more medical practitioners use natural methods to adjust sleep and mood disturbances? Why or why not?

Yes, of cause. Chronobiology sounds so useful, so why not. I prefer a natural method to cure people, because we should not be too relied on chemical products. We should rely on our own body. That’s kind of what all Chinese thinks. We are part of the nature so we should stay natural.
