It isn't as easy as you think.

People who sleep fewer than eight hours each night are more likely to feel overwhelmed, irritable, and angry, according to the American Psychological Association. They’re also more likely to see a year-over-year increase in stress. Plus, sleep loss may double the amount of norepinephrine, a hormone that can raise your heart rate and blood sugar, according to one study published in the Journal of Clinical Endocrinology and Metabolism.And because stress can also interfere with sleep, sleep loss and stress feed on each other. Luckily, if you’re having trouble sleeping, there are a few simple tricks to try. Stick to the same bedtime every night, lay off the booze, and read a book instead of staring at a screen before hitting the hay. And you can always opt for a nap, which has the power to stave off some of the negative effects of sleep loss and decrease the amount of stress hormones in your body.

We live in a world where we're constantly plugged in and on the go, so much so that it makes it nearly impossible to get the recommended seven to nine hours of sleep each night that our body needs. And boy do we need that recharge.

A CDC survey showed that 35 percent of Americans say they get fewer than seven hours of sleep nightly, which is alarming on a lot of levels. We need our zzzs so that our bodies can reset and help manage our daily stress. If that isn't enough to get you to knock off for the night, we also need sleep for weight loss.

If you think catching up on sleep over the weekend will help fill the deficit you experience during the week, think again.

According to Greatist, a sleep study followed participants who slept six hours per night for a period of two weeks. Their physical and cognitive abilities became so impaired they were on par with someone who had been deprived sleep for two nights in a row. Even scarier? The study participants largely didn't even realize they were sleep deprived, assuming that haziness as part of their usual disposition.

So catching up on sleep is possible if you only need to grab a couple of hours here or there, but the less sleep you give your body over time, the harder it is to make up.
