According to Stanford University School of Medicine researchers, a good night’s sleep may even help fight cancer.
The quality and quantity of a person’s sleep can have a tremendous affect on the balance of hormones in the body. That fact makes the sleep/wake cycle (circadian rhythm) a prime candidate for linking cancer prognosis to a person’s quality and quantity of sleep.
The circadian rhythm involves the hormones melatonin and cortisol.
Melatonin is produced by the brain during sleep. It is a strong  antioxidant. Antioxidants remove damaging free-radical compounds. People with an altered circadian rhythm produce less melatonin. That means that their cells are less protected by the strong antioxidant affects of melatonin and more prone to cancer-causing mutations.
Melatonin has also been shown to slow estrogen production. In many forms of breast and ovarian cancer, estrogen causes cancer cells to continue to reproduce. Workers on night shifts produce less melatonin and are therefore more prone to cancer.
The second possible link involves the hormone cortisol. It normally reaches peak levels at dawn and declines through the day. Cortisol  helps regulate immune system activity. This includes the activity of natural killer cells that help the body fight cancer.
Research has found that women with breast cancer whose normal cortisol cycle was disrupted — their peak levels occurred in the afternoon instead of at dawn — died earlier from their cancer.
The women with the disrupted cortisol cycle tended to sleep poorly, to have lost a spouse, and to have cancer-fighting ability of their immune system suppressed.

Sleep and Health/Disease
Dr. Keith and Laurie Nemec comments:
To have a healthy immune system to fight off or prevent cancer, bacterial, viral, parasitic and fungal infections you must get a good nights sleep.  The two hormones involved in the immune system and sleep are melatonin and cortisol.  Melatonin (only in the natural state and not in supplement form) is a powerful antioxidant consuming free radicals in the body that can cause cancer.  Cortisol is closely linked to killer cell activity which are the white blood cells that kill cancer cells.  To get these two hormones in the proper health maintaining range one needs to get to bed by 8:30 p.m. and wake up by 6:00 a.m.  This is 9.5 hours of sleep which is ideal for health and healing of a human being.  The best way to shift your sleep pattern to going to bed earlier is to start getting up earlier.  The earlier you get up in the morning the more tired you will be at 8:00 p.m. and will get to bed.  Remember this isn’t an all or none situation.  If you are used to going to bed at 11:30 p.m for each half hour you get to bed earlier your immune system is boosted proportionately.  Get up early and have your prayer time, exercise time, quiet time in the morning–early.  Also, remember night time is flesh- feeding time and spent on waste of time activities like watching television.  Get to bed early, get up early and be prepared for your day.
Spirit
Who Are You?
You are a spirit being who has a mind, will, and emotions, who lives in a physical house we call your body. 
Today we will describe the second division of your mind which is your conscious mind.
 

Conscious Mind
This is the thinking, figuring, calculating, planning mind. This is the mind most people live in and from. This mind is where the lie, from the first broken covenant between God and man, when Adam ate of the tree of the knowledge of good and evil, entered. This is the old preprogrammed mind that does what it does because of what it has been taught by a world system of lies, by family and friends that also have been trained in lies, in false belief systems, which have been passed down through the generations.  Unfortunately 95% of our lives are lived from this part of our mind when only 5% should be. The 5% is how much is needed to do the basic activities of daily living, which become almost automatic. The other 95% should be lived from the Truth-filled heart/spirit flowing into the supremeconscious mind. The reason the conscious thinking mind is the greatest blockage to our total health and wholeness is because it has been preprogrammed with the lies. The lies says, “You can do it all by yourself, you are the ruler of your universe, there is no God outside of yourself, the physical world is all there is, physical laws cannot be broken, all things are not possible, it must be right if everyone else believes it and does it.” That is why it is the conscious thinking mind that must be stilled. It is the old lie-filled conscious mind that must be put to death, so that it can come back to life programmed with Truth and Life, programmed with what is Right, what is Truth, with Love, with what is the Way, with Life. In life one must die to the old lie-filled mind, still the never ending chatter of the thinking mind (raging waves in the ocean of the thinking mind), to hear the drops of Truth that are always falling upon the Truth-filled pond of your heart/spirit. Those drops of Truth radiate and touch every part of your being, and once they have touched your being, you radiate and resonate as a shining light, as a frequency of love, to touch the entire world with that Truth that has been placed in you.
