Lack of sleep affects the brain in multiple ways that can impair concentration, judgment, alertness, impede reaction times, and decrease attention. It also increases the likelihood of drifting off to sleep.

This could be embarrassing if you are at a social gathering. And, it’s very dangerous if you’re driving, or working a production night shift with sophisticated tools. With driving, you can equate it to driving drunk, and the same applies to running a production night shift.

Some of the biggest recent disasters including the 1979 Three Mile Island nuclear accident, the massive Exxon Valdez oil spill, and the 1986 Chernobyl nuclear meltdown were related to sleep deprivation

The jury is still out on the full effects of sleep deprivation for some higher level cognitive capacities including perception, executive functions, and memory.

Insomnia And Depression

Insomnia has the highest link to depression. In fact, insomnia is one of the first signs of depression. If you’ve ever experienced ongoing loss of sleep for a number of days or longer, have you noticed the way you look in the morning? Most people have puffy eyes and sallow skin tone.

In addition, chronic sleep loss can cause dark circles under the eyes, and fine lines. If you care about the way you look whether it’s for personal or business reasons, remember that constant lack of sleep can help age your skin.

Why Does That Happen?

It has everything to do with the stress hormone cortisol. When you don’t get enough sleep, the body simply starts releasing an excess amount of cortisol. And, the end result is that cortisol starts breaking down collagen, which is the protein that the skin depends on to maintain an elastic and smooth look .

Lack of adequate sleep can also have a negative effect on your eyes. Your eyes need to replenish themselves properly and that means they need at least five hours of sleep every night.

Are There Side Effects?

The main side effect that sleep deprivation can cause is eye spasms which will have an effect on your productivity. Even though these spasms don’t cause pain or affect your vision, they are annoying and irritating. Can you imagine going to a job interview, or delivering a presentation in this condition?

Stress and eye inflammation are also related to lack of sleep. The bottom line is that you will not be functioning at your best.

The “Whitehall II Study” by British researchers reviewed 10,000 plus British civil servants over two decades to determine if sleep affected mortality. Their findings, published in 2007, showed that individuals who cut their sleep from seven to five hours or less a night almost doubled their risk of death from all causes. Data also showed that lack of sleep doubled the risk of death from cardiovascular disease.
