Day and night are the natural rhythm of life. For millennia before electric light was developed people had to live in a largely natural cycles of light and dark. It is expected, therefore, that the human body has used this cycle to promote health and to vary too far from them would have negative consequences. It seems to be the case. Sleep disorders, depression and even aging and cancer are some of the conditions that have affected the poor 'hygiene light ".
Every person has a master biological clock that regulates the production and release of melatonin from the pineal gland. Melatonin helps us sleep and is produced at night than during day time. It also has two very important roles. Melatonin is a part of the serotonin times - this is one of the "feel-good" hormones, and deficiency is known to contribute to depression and seasonal affective disorder. Melatonin also contributes to the good functioning of the immune system and is recognized role in controlling at least some forms of cancer and reducing the impact of aging.
Melatonin is a particularly strong antioxidant, reduces the cancer's ability to grow and stimulate the immune system to increase its ability to deal with cancer and infection. This was the subject of a wide range of animal and human research with knowledge of its usefulness in inhibiting cancer that reaches more than 30 years.
So you can see that it is highly desirable to hormones. Unfortunately, modern society is not good, "the light of hygiene," which encourages significant production of melatonin -. In fact, quite the opposite
culture in the Western world it is considered socially desirable for a person who likes to party well into the night, but that the person who enjoys getting up at dawn. Today it is much more common for city people spend most of their workday indoors, no matter what time of year. Heating in winter and air conditioning in the summer also contribute to our indoor lives.
We also have a medically induced fear of exposure to the sun, because the risk of skin cancer. We are strongly encouraged to stay out of the sun. [But this in mind that far more people die from low vitamin D causes cancer and heart disease than ever dies from skin cancer. We get most of our vitamin D from the sun .]
In addition to the social desirability of staying indoors a lot of people routinely wear dark glasses when going out in the sun, which prevents the eyes from getting a strong dose of light we need to increase the production of melatonin during the night.
Maybe it's time to rethink our lives. Here we have a natural treatment for cancer, depression and aging - the one that the body produces on its own as long as you provide the raw ingredients -. And most of us do not know about it
Our body needs a regular bright light. Even in winter the light of those places closer to the poles often have more light than you carry in yourself. Our body also needs regular darkness, deep darkness of the kind that occurs when there is no moon.
Our bodies do not learn to adapt to the environment in which we live, but it seems that adaptation is possible only to a point.
It might be useful to leave in the middle on a regular basis to get some bright sunlight in order to increase levels of melatonin and vitamin D (vitamin D is another natural anti-tumor agent). Consider also going to sleep earlier in the evening and waking up at dawn -. Nature and natural cycles can have significant health benefits
