What is a good night sleep? They compared women over medium and long term who got 5 hours or fewer regularly to moment who managed to get regularly 7 hours sleep on their weight.
The findings were interesting.The group who sleeped up to 5 hours were more likely to add 33lb over a 16 year period which is 30% more likely when compared to the women sho managed to get 7 hours each night. Also, the light sleepers have a significantly higher risk becoming obese.
The kicker is the researchers found that sleeping patterns had a much greater influence on women's long term weight that Eating Habits and Physical Activity!
The group of women that slept 5 hours or less weighed 5.4 lbs more at the start of the study than the group that got 7 hours or more. They also put on 1.6 pounds more EACH year than the good sleepers.
So over time the 1.6 pounds can really add up. The difference increases between the groups over a 20-30 year period about 32lbs over 20 years.
How is this possible? The reasearchers said that hormones which regulate appetite are affected after just a few nights of sleep restriction. What is surprising is that those who sleep less actually eat less than those who get adequate sleep. This shows that sleep is a much greater contributor to your long term weight than diet.
Also, they that people who sleep well fidget more during their waking hours which helps burn more calories. It is also most likely that hormones are tweaked in such a way as a result of how much we sleep - and this has a bearing on how many calories we burn off each day.
In order to stay/get slim, people have to focus on three factors:
-- Adequate sleep
-- Nutrition
-- Physical activity
Ask any professional sportsperson what the secret of top fitness is, and they will all say it is a combination of good training, eating the right foods and sleeping well - get one of those three factors wrong and you seriously undermine your chances of weight loss and preformance.
