Listen up, night owls: If you're sleeping six or fewer hours per night, you're not doing your health any favors.
A finds that getting the recommended seven to nine hours of sleep per night may help you tame your sweet tooth.
Researchers at King's College London recruited "short sleepers" 鈥� that is, people who routinely sleep less than seven hours per night. The participants were coached on strategies to extend sleep time, such as cutting back on caffeine, reducing screen time and sticking to a regular bedtime each night.
Based on this coaching, the short sleepers began to sleep about one hour more per night. And here's the fascinating part: They also changed their diets 鈥� without being asked.
"We found that those who extended their sleep [also] reduced their intake of added sugars by about 10 grams per day," explains one of the study authors, , a doctoral candidate at King's College London.
That's about 40 calories' worth of sugar, which is not a huge change. But over time, a small, daily decline in sugary foods could make a difference.
The study, which is published in the American Journal of Clinical Nutrition, is small. It included just 42 normal-weight participants, and it doesn't prove that sleep is the key to diet change. But the findings serve up more evidence that our sleep can influence our eating habits and waistlines.
A study published back in 2013 found that just five. In that study, people were allowed to sleep for just five hours for a five-day period. They gained, on average, almost 2 pounds.
And as we've the timing of meals 鈥� independent of sleep 鈥� can also influence how our bodies respond to all the calories we eat. For instance, a study published in the International Journal of Obesity found that people who eat their main meal early in the day are , compared with people who eat a heavy, late-night meal.
It seems we humans are. And we require regular sleeping and eating habits to keep our body clocks in sync 鈥� and our health in check.
