Why Lack Of Sleep Is Bad For Your Health

Many effects of a lack of sleep, such as feeling grumpy and not working at your best, are well known. But did you know that sleep deprivation can also have profound consequences on your physical health? One in three of us suffers from poor sleep, with stress, computers and taking work home often blamed. However, the cost of all those sleepless nights is more than just bad moods and a lack of focus. Regular poor sleep puts you at risk of serious medical conditions, including obesity, heart disease and diabetes – and it shortens your life expectancy. It’s now clear that a solid night’s sleep is essential for a long and healthy life. How much sleep do we need? Most of us need around eight hours of good-quality sleep a night to function properly – but some need more and some less. What matters is that you find out how much sleep you need and then try to achieve it. As a general rule, if you wake up tired and spend the day longing for a chance to have a nap, it’s likely that you...

Can You Really Sleep With Your Eyes Open?

Sleeping with your eyes open sounds like something from a horror film, but it’s a real condition called nocturnal lagophthalmos. It occurs when the eyelids can’t close enough to cover the eye—either partially or fully. Surprisingly, the condition is quite common. As much as 20 percent of people experience it, and it even occurs in babies. It can be hereditary, so if you sleep with your eyes open, your infant might, too (but most children grow out of it). However, if you still experience nocturnal lagophthalmos as an adult, it’s important to check in with a doctor. First, sleeping with your eyes open robs your peepers of important moisture. When your eyes are closed throughout the night, tears help clean and repair your cornea. That’s why the condition can lead to dry eyes, blurred vision, infection, and even permanent vision problems, if not treated. But eye irritation isn’t the only problem your physician will check for.

Sweet Dreams: How Sugar Impacts Your Sleep

Who doesn’t love a delicious after-dinner dessert? But digging into those cookies or that bowl of ice cream means that you’re pumping lots of added sugar into your body—something that can negatively impact the quality of your sleep. In fact, the more sugar that you eat during the day, the more often you’re going to wake up in the middle of the night. Even if you don’t fully wake up, the sugar in your system can pull you out of a deep sleep, making you feel exhausted the next day. On top of that, consuming too much sugar during the day can lead to an energy crash. Eating lots of sugar reduces the activity of what are called orexin cells. As a result, you’re going to feel pretty sleepy. Ever wonder why you want to take an afternoon nap after chowing down on something indulgent? That’s why. To avoid those nap-inducing energy dips, you want to do everything that you can to keep your blood sugar level steady. Do that and you’ll keep your en...
