If Your New Year Resolution Is Weight Loss… Change Your Duvet!

Posted on 29 / 10 / 2013 by Sleep Lover

If losing weight is going to feature on your New Year’s resolution list then it may well be worth thinking about putting a new duvet on your Christmas list.  Whether it’s a washable duvet, luxury goose down or anti allergy duvet make sure you get the right one to suit your needs and help you get a great nights’ sleep.

It’s well documented that getting enough good-quality sleep is fundamental to health. Sleep is a key component of successful weight loss and it’s all about how sleep affects your hormones.

How?  It’s not that complicated and we’ve translated the science bit for you!

· Amygdala Recent research has confirmed that less sleep increases the power of your primal brain to demand high-caloric food. In a controlled test, at the end of the first week the subjects whose sleep had been restricted to five hours gained an average of 2.2 lbs. in bodyweight. Brain scans performed on the sleep-deprived subjects indicated that when they saw calorie-rich foods there was a higher amount of activity from the amygdala in the brain.  The study concluded that a lack of sleep could inhibit self-control and decision-making.

· Adenosine A lack of meaningful sleep creates a build up of adenosine in the body. Adenosine is a neurotransmitter that has properties to slow down nerve cell activity and enhance drowsiness. It’s normally ‘processed’ out of our system during a restful night’s sleep.

· Ghrelin Another study highlighted a relationship between the up regulation of ghrelin and the down regulation of leptin during sleep deprivation. Ghrelin is your hunger stimulating hormone and leptin, an appetite-suppressing and metabolism-boosting hormone that regulates food intake. If leptin levels down regulate then a communication signal is sent to the hypothalamus (a gland in your brain) signalling low food storage and this can then lead to excessive food intake. This study mirrored the overeating tendencies from the two studies above.

Similarly, getting sufficient sleep after exercise to allow your muscles to repair helps to improve your basal metabolic rate – the amount of energy your body needs daily at rest, says Nicola Addison.  And she should know  – she owns a gym frequented by models Erin O’Connor and Daisy Lowe.
