Main article: Science and technology in Africa Technology in Africa has a history stretching to the beginning of the human species, stretching back to the first evidence of tool use by hominid ancestors in the areas of Africa where humans are believed to have evolved. In Nubia and ancient Kush, glazed quartzite and building in brick were developed to a greater extent than in Egypt. Parts of the East African Swahili Coast saw the creation of the world's oldest carbon steel creation with high-temperature blast furnaces created by the Haya people of Tanzania. Mesopotamia[ edit ] The Mesopotamians were one of the first to enter the Bronze Age in the world. Early on they used copper , bronze and gold , and later they used iron. Palaces were decorated with hundreds of kilograms of these very expensive metals. Also, copper, bronze, and iron were used for armor as well as for different weapons such as swords , daggers , spears , and maces. Perhaps the most important advance made by the Mesopotamians was the invention of writing by the Sumerians.
Technology, Gadgets Use May Change Human Body Clock; Here's What to Do Mark Bustos Facebook Twitter Linkedin Comment Mail Close Since the light bulb was patented inmankind has been guided day and night by artificial lighting, now available from television sets to smartphone screens - and a growing body of research proves their effect on our circadian rhythm. Basically, using gadgets with screens during nighttime interfere with our ability to get that good night's sleep.
While there are apps and products that supposedly help mitigate the effect of artificial lighting, the relationship between technology and the body clock is not as simple as it seems. In humans, this is regulated by the hypothalamus, a part of the brain that releases a hormone known as melatonin.

Also known as the sleep hormone, melatonin levels in humans generally increase at night and drops before we wake up. While it has a built-in, natural pattern, the cycle of melatonin release is also affected by ambient light. As for the effect of light - from the light bulb to the smartphone screen - Stanford University professor explains Jamie Zeitzer explains in an online forum"light is mainly doing two things to the clock. It is setting the time of the clock and Technological Changes In Human Civilization is changing the amplitude or strength of the clock. A study reviewed existing phototherapy techniques and their effect on addressing sleep problems.
Researchers found out that light therapy is generally effective for sleep problems, especially for circadian rhythm outcomes and symptoms of insomnia.
Is Resetting the Body Clock Possible?
Is Resetting the Body Clock http://pinsoftek.com/wp-content/custom/life-in-hell/a-comparison-of-high-noon-and-the-most-dangerous-game.php While self-help blogs and lifestyle publications might have varying suggestions on how to get your body clock back on track, the common elements are in reducing nighttime exposure to artificial light, especially a few hours before sleep. Additionally, there have been a few published studies on how to reset a person's circadian rhythm. A January study led by the Douglas Mental Health University opened the pharmaceutical potential of steroids in resetting the circadian rhythm.
Understanding the Human Circadian Rhythm
In their study, researchers observed sixteen volunteers in temporal isolation chambers, finding that the peripheral biological clocks in the white blood cells can actually be synchronized through the intake of glucocorticoid tablets. A more recent study, appearing in the February issue of Current Biologyre-trains the body to adapt to the seasonal changes based on the natural day-night cycles. With the natural light-dark pattern, the human body clock adapts. This is achieved by a typical weekend camping trip.]
At all I do not know, that here and to tell that it is possible
I congratulate, your idea is very good
