1.
Britain may be the most red-headed country in the world. About 1 to 2 percent of the world’s population has red hair, but in the UK the numbers are much higher, with 13 percent of Scots, 10 percent of the Irish, and 6 percent of people in England having red hair, according to the BBC.
2.
Scientists have tried to explain why some people have red hair for some time and now they may have found an answer: the dull weather in Britain. The human body needs vitamin D from sunshine, but unfortunately people living in Britain do not have enough of it because of its maritime climate. In fact, Britain gets even more cloud than countries in the far north of Europe. In Sweden, for example, the average daily hours of sunshine is 5.4 . In Scotland it is only 3.1 hours.
3.
To deal with this, the DNA of people living in these areas has changed slightly; scientists call this a mutation. Originally, the coloring on our body is a mixture of two kinds of melanin – black melanin is suppressed while only red / yellow melanin is made. The result is red hair, light skin color, freckles and a greater sensitivity to sunlight.
4.
However, what’ s more interesting is that the redhead DNA mutation is recessive, which means it is hidden and can often skip generations without showing. At least 1.6 million Scots carry a redhead gene mutation, and most are unaware that they do. This is why a person who does not have red hair can still produce red-haired children if he or she is a carrier of this special DNA.
5.
The research on red hair, like many areas of science, is contradictory(不一致). In 2002 researchers showed that redheads are more sensitive to pain, and need more anesthetic during surgery than people with blonde or dark hair. However, in 2005 scientists found that a MCRIR mutation gives redheads a higher tolerance for pain. Research into these aspects of red hair genetics continues. Redheads should though be more careful about their exposure to sunlight as they are at an increased risk of contracting skin cancer. If you are a redhead, the advice is not to stay out of the sun, but to be careful about how much exposure you get, and to cover yourself with a high factor sunscreen.
Most people who live in Seattle, Washington, love their city. There is a never-ending flow of fun things to do. But, people who live there do not always enjoy the day-after-day absence of sunshine during the winter months.
It is documented fact that sunshine (or lack of it) plays a major role in how each of us meets the day. It also affects how we perform at school or work. When people are derived of sunlight, they can develop seasonal affective disorder, which makes it difficult for them to feel happy or get things accomplished. No major city in the United States is more affected by the “sunshine factor” than Seattle.
To fight drizzle and fog during the winter months, Steve Murphy created a business that is very popular among the locals. The Indoor Sun Shoppe is more than a little ray of sunshine during the gray days of Seattle’s winter. His shop offers a huge source of plants and artificial lighting for people who are trying to overcome seasonal affective disorder.
Located in Fremont, Washington, The Indoor Sun Shoppe has an amazing collection of exotic plants and “good bugs” in a humid and well-lit environment. At The Indoor Sun Shoppe, you can spend up to $400 for artificial lighting that will chase away the winter blues. It will also keep your plants healthy. You can buy a dawn simulator that will gradually fill your room with a warming wake-up glow. What better way to meet a Seattle morning when real sunshine is nothing more than a happy thought!
