Extending Bed Time with Extra 20 Minutes Could Limit Sugar Cravings

The study found that 86 percent of those in the sleep-consultation group ended up spending more time in bed, and half of them slept longer: between 52 and 90 minutes longer, to be exact. There were no significant diet differences shown in the group who did not change their sleeping habits during the study. The team also noticed a decrease in the amount of carbohydrate intake in the daily diet.

Researchers at King's College London conducted the study by recruiting 42 healthy people of normal weight who were a little sleep deprived - getting less than seven hours of sleep a night.

In the study, the researchers recruited 21 individuals to participate in a 45-minute sleep consultation created to extend their sleep time by up to 1.5 hours per night.

A recent study has found that an extra 20 minutes of sleep could help people in cutting down the consumption of unhealthy food and sugar by nearly 10g. In the United States, that number looks much the same: The Centers for Disease Control and Prevention (CDC) reports that one in three adults is not getting the suggested seven-hour nightly minimum.

And they also cut down on their carb intake. The remaining 21 volunteers received no such advice.

The researchers found extending sleep resulted in a 10-gram reduction in reported intake of free sugars - the sugars added to foods by manufacturers or in cooking at home, as well as sugars in honey, syrups and fruit juice - compared to the amount consumed at the start of the trial.

Sevilla opted to increase prices by £35 from the amount they charged Liverpool fans for their group encounter earlier in the season.

The team suggested that any new sleep routine will take some time to get used to.

Lead researcher, Haya Al Khatib, also from Kings College added: "Sleep duration and quality is an area of increasing public health concern and has been linked as a risk factor for various conditions". During this time, the participants also wore motion sensors on their wrists that measured the exact amount of sleep they got each night, as well as the amount of time they spent in bed before they actually fell asleep.

A new study found that an extra 20 minutes of sleep could be the key to shedding excess pounds but when talking about the previous study, it may not seem like the obvious way to lose weight.

Increasing time in bed for just an hour or so could impact the food choices we make, Khatib also notes.

"We hope to investigate this finding further with longer-term studies examining nutrient intake and continued adherence to sleep extension behaviours in more detail, especially in populations at risk of obesity or cardio-vascular disease".

As if we needed an excuse to stay in bed longer...
