Sleep is one of the most important things a person needs to do in order to maintain their health. Sleep is necessary to heal and the human body needs it in order to maintain or return to a state of health. Sleep is a little bit more complicated than it appears. While most people think they should just go to bed and make sure to get some sleep every night, it is most important to get the correct amount of sleep as well as during the optimum times for health. Without sleep a person will deteriorate and become unhealthy. The optimum hours that a person should make sure to sleep between are 10 p.m. to 2 p.m. Also, it is thought that even though some people might think they feel just fine only sleeping 5-6 hours per night, it is actually strongly recommended to sleep for at least 8-9 hours per night or more.

Sleep is extremely important for people to stay healthy, mentally fit, alert, as well as maintain body weight. If a person does not get enough sleep it can literally drive them insane. Sleep is one of the body's health effectors and plays a definite role in mood, attentiveness, weight, immunity, and a sense of overall well being. When people are unable to sleep they can show a decline in their health. Some individuals have no real choice about when they sleep because they work graveyard shifts or rotating shifts. When this happens it throws off the person and can be very stressful internally, even if the person does not outwardly show it. One way that lack of sleep affect a person's health is by holding extra weight.

The number of sleep disorders being diagnosed is rising. With the continuous advent of new technology doctors are able to catch and properly diagnose sleep disorders, as well as develop better technologies to treat them. Some of the most bothersome sleep disorders that impact health and a good night's sleep are Obstructive Sleep Apnea, Restless Leg Syndrome, snoring, Narcolepsy, and Insomnia. There are also other disorders that have side effects of troubled sleep, such as Chronic Fatigue Syndrome or Post Traumatic Stress Disorder. Lack of sleep can also trigger problems for individuals. For example, lack of sleep is a migraine trigger for many. Chronic pain also has a huge impact on sleep quality.

Jet lag is a problem for many people. The internal clock in the body is thrown off as the circadian rhythms get disrupted by the travel through different time zones. It is better to rest up and repair than plug along with jet lag. One group of people who have to be especially mindful when traveling are those with Bipolar Disorder. Jet lag can trigger episodes in some people with Bipolar. Jet lag seems to be a phenomenon that people have to just deal with rather than something that is taken seriously. For some people it really affects them physically and mentally, the slight sleep deprivation and time zone change enough to throw a person into chaos internally. Instead of trying to shake it off or deal with it and be tired people need to take jet lag seriously because it does impact a person biologically.

Another area where sleep hugely affects society is at the wheel of a car. Sleepy driving is responsible for a large number of fatal car wrecks every year. Drowsy drivers are one of the biggest dangers on the road. Driving while drowsy will impact a person's response time as well as their coordination. It is definitely an area where people need to be self aware and not travel or drive, even short distances, if they are tired. Some people drive for a living and this can be a major challenge.

Overall, sleep is an extremely important health factor. It impacts the body in many ways and is one of the most restorative activities a person can do.
