Sometimes we don't get enough, sometimes too much, and others we get just the right amount; but everyone needs sleep and no one can avoid it for too long. It is the single best way way to refresh the body and to relieve daily stress and tension. There's nothing better than being able to lie in a nice bed at night after a long day drift into a peaceful sleep. While we all do it, it is very complex in its own nature, being classified into four stages and two types, REM sleep and NREM sleep. During sleep the brain is extremely active, as we dream. However, while some of us dream, others have to deal with a variety of sleep disorders. Sleep disorders are common, and you've probably heard of many, but here are some weird sleep disorders that may open your eyes. So relax and enjoy a top 10 list of bizarre sleep disorders. Don't let them keep you up at night.
More commonly known as teeth grinding, sleep bruxism is when someone, while sleeping, is known to clench or grind their teeth together. Many say that it is caused by stress, tension, anxiety, suppressed anger, or something as simple as a misalignment of the teeth. Simple treatments are given to correct the problem generally, such as a mouth guard or therapy. Though the condition doesn't seem very serious, in many cases sleep bruxism can become an issue. If the bruxism carries on for too long, it can lead to jaw disorders, damaged teeth, headaches, and other problems.
磨牙症更常见的表述是teeth grinding，其症状表现为：一个人在睡觉时咬紧牙关或者磨牙。通常认为磨牙是由于压力、紧张、焦虑、压抑愤怒或者仅仅是牙齿咬合不正引起的。一些简单的治疗措施，例如进行口腔防护或治疗，正常情况下就可以矫正这个问题。 尽管磨牙听起来并不严重，但不注意会成为很大的健康隐患。如果长期磨牙，可能导致上下颚咬合不正，造成牙齿损伤、头疼，甚至引起其他问题。
Sleep apnea is a very serious condition that is marked by the stopping and starting of breathing during the night. It is said that the condition elevates the risk for a stroke. Doctors say that loud snoring or waking up feeling tired even after a long nights rest may be indicators of sleep apnea. There are two main types of sleep apnea: obstructive, which is when the throat muscles relax and the airways narrow or close, and central sleep apnea, which is when the brain fails to send messages to the breathing muscles. Sleep apnea can be due to excess weight, high blood pressure, smoking, or a history of the disorder. Also, find information on how to stop snoring.
Better known as sleepwalking, somnambulism is said to be a pretty harmless condition that many people grow out of over time. However, it can be serious in some cases, as those who sleepwalk generally do daily tasks, so a sleepwalker could easily get into a car and drive. It is said that 15% of children between the ages of 8-12 experience sleepwalking. Many times the person who sleepwalks will not remember it, but may wake up with glassy eyes or speaking clumsily. Sleep walking it usually caused by an underlying problem, such as seizures, sleep apnea, PTSD, or arrhythmias, and is therefore not treated. Instead the cause of sleep walking becomes the main focus.
We've all been tired during the day at some point in time, but people with narcolepsy are generally extremely tired during the day and will often experience sudden sleep spells. Narcoleptics can be extremely serious, but there is still no known cure. One out of every 2,000 people is said to have narcolepsy. Plenty of treatments exist, but none fully get rid of the condition. Doctors believe that brain chemicals, notably hypocretin, play a large role in narcolepsy. Generally these cells are excessively damaged, which causes disruptions to sleep patterns, as hypocretin is known to regulate the REM sleep cycle as well as staying awake. However, no one knows why these cells are damaged, and how they become damaged.
6.Restless Legs Syndrome (RLS)
Restless Legs Syndrome (RLS) is classified by a strong and urgent need to move the legs. The urge is said to be extremely hard to resist, as there are often uneasy feelings felt inside of the legs. Some say it's a prickling sensation while others say it's more of a tingling feeling. In any case, the sensations can be painful, which makes sitting or lying down hard for those with RLS. RLS is a sleep disorder because the condition is said to be its worse at night and then eases off in the morning and it causes disruptions to normal sleep patterns. It is said that 5%-10% of people in the U.S. and Northern Europe will experience RLS.
