Not long ago, what is now considered a healthy skin tone was considered a mark of a low social status. What was called a farmer tan, was the result of long days working in the fields on a regular basis, and farming did not fit well with high society. Fashion has a way of making dramatic swings, and now a well developed sunblock tan is essential to looking beautiful.
To get a true healthy sunblock tan, one must turn to the source of energy for the planet; the sun. In addition to providing the true source of nutrition through photosynthesis, it impacts many other facets of life as well. It is so vital that the most accepted theory for the extinction of the dinosaurs is the temporary blockage of the sun, which was nearly complete a terminal event.
In ancient times, the sun was so important that it was worshiped, with the Egyptians naming the Deity Ra. Culture has long included facets documenting the understanding of the central position solar energy plays in allowing life on earth, even beyond the appeal of a sunblock tan. Science has developed a number of theories about the relationship between the solar cycle and human health.
Deep within the brain there is an endocrine gland known as the pineal gland, whose purpose is not entirely clear. What science knows is that the gland produces a derivative of serotonin known as melatonin, which helps regulate human sleep and wake cycles. Melatonin also plays a role in the ability to attain a sunblock tan, by controlling the aggregation of melanocytes in the skin.
Exposure to the sun helps develop a sunblock tan through activation of melanocytes in the skin, the aggregation of which is controlled by melatonin. This same hormone also affects how drowsy people become; an increase in the hormone increases the drowsiness. There is a control mechanism; when sunlight reaches the retina of the eye, it inhibits the release of the hormone, which is why we are drowsier on overcast days.
The affect of the sun goes even deeper, beyond the desire for a sunblock tan, to implications that there its actions can directly promote good health, and a lack of exposure can initiate disease. Specifically, science has discovered a strong correlation between higher latitudes and the incidence of mortality due to multiple sclerosis. The higher the latitude, the less intense the suns rays.
There are also detrimental effects of too much exposure, commonly sunburn, but more seriously skin cancer. Directly attributable to overdosing on the solar rays, it is the condition those seeking a perfect sunblock tan must be careful to avoid. Limiting the time one remains in direct sunlight is the best answer, and even in tanning booths there is a concern.
For humans, too much of almost anything is a bad thing, a concern when perfecting a sunblock tan. The skin hue is not the concern, but the exposure to UV radiation is problematic. The products allowing us to safely develop a sunblock tan have improved greatly, but caution is critical.
