Can Sleep More Slim Us Down? “Don’t sleep too much as this will make you fat!” This is the statement I used to hear from people around me, especially the elderly ones, since I was young. I did not ask why or I supposed even if I asked, I doubt I would get the answer. Nevertheless, this statement seems to contradict with what I have read the other day about an article saying that sleep more to slim down. Researchers from France's Inserm argued that more sleep could be the ideal way of stabilizing weight or slimming. In fact, their study showed that an extra hour of sleep at night might help cut excess weight and fight obesity. Since obesity or overweight is confirmed as one of the possible risk factors that could increase the chance of heart disease, diabetes, high blood pressure, and certain types of cancer, people have every good reason to maintain their healthy weight at all time. Unhealthy diet and lack of exercise are surely the cause that leads to obesity, but recent data indicates that lack of sleep might also be a factor that is too often being under-estimated.
Around 30 surveys being carried out on wide population samples in 7 countries, and the findings have highlighted the link between lack of sleep and excess weight or obesity in both children and adults. According to the researchers, the very first study was carried out in 1992 highlighting the problem in children and teenagers, and the rise in obesity in the United States in the second-hand half of the 20th century revealed its link with decrease in sleep. Grehlin and leptin are the 2 key hormones produced at night to help regulate appetite. Grehlin makes people hungry, slows metabolism and decreases the body's ability to burn body fat while leptin regulates fat storage. The study found that less sleep (two 4-hour nights) caused an 18 percent loss of appetite-cutting leptin and a 28 percent increase of appetite-causing grehlin. This will definitely make people hungry for foods high in fats and sugars like biscuits, cakes, chips, and peanuts. 23 to 24 percent increase in hunger was noticed as a result of sleep loss. Such change would translate into an extra 350 to 500 kilocalories a day, which for a young sedentary adult of normal weight, could lead to a major amount of added weight. However, it was not clear if several years of sleep deprivation could eventually harm the body's ability to restore a balance between the 2 hormones. Another study by Johns Hopkins Bloomberg School of Public Health published in the journal Obesity in February 2008 found that children lack of sleep faced a greater risk of becoming obese than kids who got good amount of sleep. In the study, 17 published studies were reviewed on sleep duration and childhood obesity and every extra hour of sleep was found to cut a child's risk of becoming overweight or obese by 9 percent. In comparison, children getting the least sleep had a 92 percent higher chance of becoming overweight or obese than children who slept enough. As recommended by most health experts, children under 5 years old should sleep 11 hours or more a day, while children age 5 to 10 should get 10 or more hours of sleep, and children older than 10 should sleep at least 9 hours.
