Ever feel guilty for wasting half of Saturday in bed? Or hitting the snooze button so many times on Sunday morning, it’s way past an acceptable brunch hour when you do rise from your slumber? Well, we have the perfect excuse for you to roll over and forget the world, because having a lie-in at the weekend is better for you than you realise.
New research claims that catching up on sleep after a busy week can actually make you smarter, healthier, and less stressed out. A recent study published in the Sleep journal discovered that people who were able reduce their sleep deficit over the weekend had lower Body Mass Indexes (BMIs) than those that didn’t. BMI is a way of calculating healthy body weight using actual weight and the height of the participant.
The study was undertaken in South Korea with a random sample of 2,000 participants between the ages of 19 and 82. Researchers interviewed them about their weekday and weekend sleeping habits, as well as their mood, medical conditions, and height and weight. They linked an extra hour in bed to a 0.12 decrease in BMI.
Speaking to Reuters, the study’s author, Dr Chang-Ho Yun, said that not getting enough sleep can disrupt hormones and the metabolism.
“Short sleep, usually causing sleep debt, is common and inevitable in many cases, and is a risk factor for obesity, hypertension, coronary heart disease, as well as mortality,” he said.
What’s more, the study went on to imply that lie-ins can also increase brain function. Getting more sleep allows your brain to process information better and increases short-term memory function.
Guess what we’ll be doing this weekend without feeling bad about it…
