Here, experts explain 12 different s of sleep deprivation, and what you need to know about them.

According to a report by the journal of Behavioural Brain Researchsleep deprivation induces oxidative stress an imbalance between free radicals and antioxidants in your bodywhich further impairs learning and memory processes.

Another thing that can suffer with poor sleep is your immune system. In particular, you might find that it's harder to shake off a cold. A study in the Archives of Internal Medicine followed the sleeping habits of volunteers for 14 days straight. Researchers found that people who got less than seven hours of sleep were nearly three times as likely to develop a cold than those who got eight hours or more rest a night.

First, skimping on shuteye tires out the ciliary muscle, which helps your eyes focus. The result: you'll have a harder time reading up close, he says.

Light can also affect the ciliary muscle. A NIH study showed a strong correlation between children who slept with the light on and near-sightedness later in life. While most adults sleep in total darkness, modern blue-light technology like TVs, computers, and cell phones can also contribute to poor sleep.

Then there's the extra ocular muscle, which moves the eye from side to side and up and down. Shanbom says, but in a well-rested person the eyes can compensate on their own. A lack of sleep makes the misalignment harder to control, potentially resulting in double vision.
