What is sleep? Before discussing how alcohol causes snoring, itâs important to have a basic understanding of what sleep is and how consuming alcohol affects sleep. Sleep is a normal, cyclical state of unconsciousness from which a person can be quickly awakened. It is as fundamental to life as food and water.
Light skin tones are complemented best by light, golden or strawberry blonde hair colors, while platinum and ash don't always look flattering. Medium skin tones can work with all blonde hair colors depending on the warm or cool undertones of your skin, but ashy blondes aren't always the right choice. Darker skin tones need to stick to the darker shades of blonde or simply try caramel or golden highlights, for a natural sun-kissed blonde hair color.
Skin Color Adaptation. Human skin color is quite variable around the world. It ranges from a very dark brown among some Africans, Australian Aborigines, and Melanesians to a near yellowish pink among some Northern Europeans. There are no people who actually have true black, white, red, or yellow skin. These are commonly used color terms that do not reflect biological reality. Skin color is due primarily to the presence of a pigment called melanin , which is controlled by at least 6 genes. Both light and dark complexioned people have melanin. However, two forms are produced--pheomelanin , which is red to yellow in color, and eumelanin , which is dark brown to black.
