Sleep – or lack thereof – can affect everything from mood to ability to concentrate and overall health. And now researchers say there’s proof that a good night’s sleep may be linked to overall healthier eating habits.

According to Reuters, a Harvard Medical School study found that truckers who regularly got adequate sleep tended to consume more fruits and vegetables and fewer sugary drinks and snacks.

Researchers studied the work, sleep and eating habits of 542 male truckers. They found that 52 percent reported getting enough sleep each night. They also said that they ate an average of three servings of fruits and vegetables, drank less than one sugary beverage and ate less than a half serving of a sugary snack each day.

On the other hand, those who reported getting inadequate sleep ate just two servings of fruits and vegetables, drank more than one drink with added sugar and ate one sugary snack each day.

The study’s lead author, Dr Orfeu Buxton, told Reuters that the findings are consistent with previous studies that have shown inadequate sleep increases hunger and induces greater eating.

Health experts recommend between seven and eight hours of sleep each night. According to the Mayo Clinic, nutritional supplements believed to aid in sleep include melatonin and valerian.
