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.
The sun is, of source of vital importance to life on planet earth, even beyond getting a sunblock tan. It provides critical energy and nutrition to all of the creatures alive today. Vegetation is nurtured by the energy in solar rays, creating nutrients through photosynthesis. While most enjoy the sun in the effort to perfect their sunblock tan, there are other reasons to seek solace in the sun.
Mankind has long worshipped Deities that represented and controlled the events he could not otherwise understand. Gods of fire, water, earth and the sun demonstrated respect for the critical elements that created earth itself. The sun was particularly revered, and now science is catching up, with evidence indicating the orb affects how man lives and some mechanisms leading to death.
In the days of Descartes, around 1625, the pineal gland, situated deep within the brain, was considered a sort of gateway between the world and the human spirit. The precise function of this gland is as yet still not completely understood beyond its function on releasing melatonin. This hormone has a number of effects in regulating physiology, among them helping one attain that sought after sunblock tan.
Another common knowledge impact of sunlight is that it makes most people feel better, in addition to the attractive sunblock tan they can achieve. Biologically the reason is melatonin, produced by the pineal, which regulates drowsiness. The release is inhibited directly by the influence of sunlight on the retina of the eye; the presence of the sunlight inhibits the release.
Sunlight also seems to directly impact some diseases, and may prevent others, so pursuit of a sunblock tan has benefits and risks. Multiple sclerosis is a debilitating disease that affects the nervous system and is often fatal, and may be prevented by adequate solar exposure. Scientists have found a direct proportionality between higher latitudes and the incidence of the disease, the connection being reduce overall sun exposure in these regions.
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.
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.
