Nursing study links poor sleep to weight gain.

Is good sleep really important if you are trying to lose weight? The answer according to research is a resounding YES!

It can be a vicious cycle. Poor sleep can lead to increased weight gain and weight gain can lead to even worse sleep. It is well know that some sleep problems like sleep apnoea can are made worse by obesity. In one study a group of nurses were only allowed 5 hours sleep per night over a 5-day period. On average they gained 1.8lbs (0.8kg). Poor sleep can also lead to an increased appetite. Studies have shown that if you sleep is not adequate the hormones that control hunger are disrupted. A study looked directly at this using a sample of 1,000 short duration sleepers and found that the hormones mentioned above varied by up-to 15%. All of the short sleeps had higher BMI, clearly displaying a correlation between short sleep cycle and weight gain.

In  a further  study  over 16 years , 60,000 non-obese nurse were observed. The outcome of the study was that the nurses that slept for 5 or less hours a night were 15% more likely to be obese than those who slept 7 or more.

The studies mentioned above are not the first to be linked to high BMI and weight gain. Poor quality of sleep has also been linked to insulin resistance.

The Better Sleep Council recommends that you replace your mattress every 7 years but the truth is that it varies wildly dependent on the quality.  The quality is particularly relevant with memory foam mattresses as they have a huge number of additives from fire retardants chemicals to softeners. Dependent on the amount and quality of chemicals used the quality varies wildly.

The Zonesleep topper has been developed to help extend the life of mattress while also eliminating the heat and sweat problems associated with Memory Foam and traditional mattress.  The Zonesleep topper has had a huge number of reviews in regards its ability to alleviate back and hip pain while sleeping.
