The spring is coming, is summer far away? I believe many girls have a great determination to on diet while seeing full of clothes in the supermarket. Recently, some researchers from USA found that sleeping is linked to fat. More or less sleeping can lead to abdominal fat increased obviously. If you are also one of these groups, let's come to see how "scientific sleep".

Younger adults who get either little sleep or a lot of it may see a greater expansion in their waistlines over time, a study published suggests recently. Researchers also found that adults who less than 40 slept for 5 to 6 hours had a greater accumulation belly fat over the next 5 years, versus those who averaged 6 over 7 hours. Those who lying in bed more than 8 hours each night also showed a bigger fat gain, but it was less substantial than that seen in short sleepers.

On average, short sleepers showed a 32% gain in visceral fat, versus a 13% gain among those who slept 6 or 7 hours each night and a 22% increase among men and women who got at least eight hours of sleep each night.

As for why sleep duration might affect abdominal-fat gain, there are several theories.

There may be indirect effects; people who get too little sleep may be too tired during the day to exercise, while those who spend a lot of time in bed may spend less time being active, relative to people who sleep fewer hours.

Research also suggests that sleep loss has a great relationship with appetite, which results in over eat that cause you getting fatter and fatter.

Depress, sad, introverted or unsettled emotions, which are often affects people's sleep and has been linked to weight gain. These are also some important factors. So sleep enough is so important, which ensure you have power to do daily exercise and have a regular eating habit.

Are you sleeping right? Don't be too lazy to do exercise or just want to lying in bed to reading, writing, eating or watching. Move your body as much as you can.
