What you might not know is that sleeping for less than 9 hours could be contributing to weight gain. Not only that but, if you suffer from sleep apnoea your chances of gaining weight are even higher.

Sleep Duration & Weight Gain

A new study analysing sleep effects on health has found that people in the study, who were sleeping for 6 hours each night had waist measurements of 3 cm wider than those who are getting 9 hours of sleep.

The research, led by Laura Hardie of the Leeds Institute of Cardiovascular and Metabolic Medicine and the School of Food Science and Nutrition at the University of Leeds, involved 1,615 people aged 19-65 in Great Britain. Laura and her team studied the relationship between sleep duration and a number of quantifiable factors such as waist circumference, blood pressure, lipids, glucose, thyroid hormones and other measures of a person's metabolic profile.

"Because we found that adults who reported sleeping less than their peers were more likely to be overweight or obese. Our findings highlight the importance of getting enough sleep," Hardie told ScienceDaily.com.

"How much sleep we need differs between people," she added, "but the current consensus is that seven to nine hours is best for most adults."

In fact, the findings of this new study show that waist circumference and BMI are lowest for people who get 12 hours sleep a night! This finding contradicts earlier studies that have shown too much sleep might have a similar impact on the body as too little sleep.

Obstructive Sleep Apnoea And Weight Gain

Another new study has revealed the vicious cycle of obstructive sleep apnoea (OSA) and weight gain. It’s a well-known fact that obesity is a leading risk factor for OSA, but a new study has revealed that OSA itself may promote further weight gain.

Ari Shechter, a Professor in the Department of Medicine at Columbia University, recently published his findings in the journal Sleep Medicine Reviews. Shechter’s findings suggest that OSA severity is linked to unhealthy dietary choices. Food preference was studied in a group of patients undergoing screening for OSA. They analysed the fibre and fat intake in the morning following the diagnostic study.

The evidence suggests that leptin levels are abnormally high in those with OSA, similar to the leptin levels seen in obesity. This may also contribute to a “leptin resistance” in OSA patients.

Leptin, also known as the ‘starvation hormone’ notifies your brain if you have eaten enough. It also notifies you if your calorie intake is sufficient. An abnormally high leptin can cause a resistance, resulting in low satiety and high hunger. Which leads to excess food intake and weight gain.

Shechter’s research validates the reciprocal relationship between sleep disorders and weight gain. But we all know how difficult it can be to get 6-8 hours sleep, let alone 9-12. Even if you don’t have OSA, getting enough sleep is vital to achieving your health and weight goals. Here are 9 things you can do today to get a better night’s sleep.

Sleep Apnoea And Weight Loss

Posted on Fri, Nov 18, 2011

Sleep apnoea has long been linked to metabolic retardation and a consequent increase in bodyweight.  In fact, in the majority of cases, people who are obese are highly likely to be suffering from some degree of sleep apnoea.

Sleep apnoea stops the sufferer from breathing normally while asleep, as the soft tissue of the upper airway collapse and block breathing.  In severe cases this happens 30 or more times per hour, often for 30 seconds or more each time.  The effect on the body's physiology is easy to imagine.

The interesting thing to note is that sleep apnoea and weight issues are a circular relationship.  Just as sleep apnoea can cause people to put on weight, it is also true that overweight people are likely to have sleep apnoea.  This leads to a downward spiral, as the weight gain leads to worsened apnoea, which leads to increased weight gain, etc.

In this article from ABC7 News in the US, one apnoea sufferer explains the difference treatment has made to her condition and her life.  One positive outcome is that her retarded metabolism appears to have been kick started again ... and she has lost 45 pounds since April.

As the report says, "As with most people who lose weight, a healthy diet and a consistent exercise regimen are part of her method. McCormick, though, chalks up her extreme weight loss to one more factor.

Breathing.

Last April, McCormick participated in a sleep study that revealed she had sleep apnea. Sufferers of sleep apnea briefly and repeatedly stop breathing while they sleep due to a blockage of the airway."

Since undergoing treatment for sleep apnoea, Rebecca says her life has "turned around completely. She sleeps eight hours a night, doesn't snore anymore, and has the energy to work out on a daily basis.

"Many times, I don't wake up at all in the night," McCormick said. "(My) emotions stabilized. I'm back to being a positive and energetic person."

Twersky says people who can't lose weight with diet and exercise alone might indeed be one of the millions who have an underlying sleep disorder. He says if you suspect sleep apnea, you should consult with a doctor about getting tested."

Sleep apnoea is a serious condition which should be treated, rather than tolerated.  If you have apnoea or know someone who does, arrange a diagnostic sleep study for them as a matter of urgency.
