Some people in this world get a gift from God in the form of a short sleep capability. They are known as short sleepers. They can meet the needs of their bed only by sleeping less than 6 hours. A report published in Science journal in 2009 states, Ying-Hui Fu (professor of neurology at the University of California San Francisco, USA) and his team were succeeded in identifying the mother and her daughter who slept around 6.25 hours each day. Uniquely, they were very energetic.

The results of blood tests showed, they have mutations that affect the cycle for 24 hours. Fu said, 4 to 6 hours of sleep was the optimum time for them because their chances of genetic mutations affected sleep patterns.

However, not every short sleeper has a genetic mutation. “It’s hard to say how often the case these mutations occur,” he said.

According to Fu, the majority of short sleepers are the people who are very active. They enjoy several hobbies, have a successful career, and have two types of work.

One of short sleepers worth mentioned here is Dan Nainan, a comedian who lives in New York. Every night he sleeps only 4 hours. In the morning, he feels fit and not sleepy even though he doesn’t drink prescription drugs and caffeine.

Nainan doesn’t know whether he is a short sleeper because of the demands of work or because of genes. What is clear for him, a short sleeper has the advantage of a 20 percent more time than the people in general. He uses that time to develop marketing strategies and comedy material.

The story of the life of a short sleeper named Amy Avery is also very interesting. This Atlanta residents sleeps in just four to five hours each night. But she is safe the next day. She doesn’t not experience fatigue or evaporate despite working full during the day. Remarkably, she doesn’t need coffee or other caffeinated beverages either.

Everyday, Avery works full time as director of digital at an advertising company. Coming home from the office, he takes care of her husband and two children aged 5 years and 2 years. After the child and her husband slept soundly on the hour at 9 or 10 pm, Avery does household chores such as washing. She also still has time to do the duties of her office, read a book, or watch television. []
