For men and women alike, health and beauty are coveted, with a healthy sunblock tan ranking high as a desirable trait. There is a sound scientific basis for the popularity of the sunblock tan; not only is it visually appealing, it is a marker of good health. As with so many things dealing with the human condition, moderation is the key.
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.
Within the brain there is a gland known as the pineal. Medical science has debated its purpose and function for centuries. That it could play a role in getting a sunblock tan was never imagined, such is the complexity of human physiology. The pineal controls the release of melatonin, which, through its impact on melanin, allows the skin to develop a sunblock tan.
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 a number of negative effects from exposure to the sun, the most obvious being sunburn, the most dangerous cancer. For most human beings, more than fifteen minutes exposure to direct sunlight begins to damage the surface of the skin. Those seeking a sunblock tan must take care not to overexpose the skin.
Science has determined that the rays are made up of three ultraviolet frequencies known simply as A, B and C. With this knowledge, a number of ointments have been developed for protection. In the pursuit of the perfect degree of sunblock tan, one must carefully use the protection and regulate the length of exposure for best results.
