Sleep Disorders
Sleep Paralysis
Sleep paralysis is the occurrence when a person may be awake or falling asleep but they are unable to move their bodies or speak verbally. In this sleep disorder, a person is fully awake and conscious of the situation. People are known to have a feeling of choking and pressure within their throats or chests. It can last up to 2 to 3 minutes.
Sleep Terror
When sleep terrors occur a person is known to scream and wail within their sleep. They are in deep fear during the sleeping process and is usually paired with sleep walking which sets a person at risk of a greater accident within their house. Sleep terrors can be due to the lack of sleep, stress, anxiety, or emotional tension that has not been handled.
Sleep Apnea
Sleep apnea is when a person has a hard time breathing during sleep and a persons breathing can even temporarily stop--this leads them to be woken up and have inconsistent sleep. It is quite common and can be seen in 200,000 cases each year within the United States. It is common in men and is known to generally affect those who may suffer from obesity or are old in age.
Insomnia
Insomnia is a sleep disorder in which a person may have trouble falling asleep at night or staying asleep at night. This can be seen in two forms acute insomnia and chronic insomnia. Acute insomnia may lasts up to 1 day to a few weeks while chronic insomnia may last up to 3 nights to 3 months or even to a longer period of time. This can be caused by stress, anxiety, poor sleepinig habts and many other factors.
Jet Lag
Jet lag occurs to those who generally travel from a location that has different time zones and this causes a person to lose sleep and sense of time. This is due to the fact that a person has an inbuilt clock known as the circadian rhythm that signals your body to go to sleep or wake up. With this messed up a person may begin to lose out on sleep and will become successive to stress or anxiety.
Benefits of sleep
Healthier Heart
When a person sleeps there is an opportunity for their blood pressure to decrease. Being consistently awake leads a persons blood pressure to steadily increase or stay stagnant at a high level. High blood pressure can lead to heart issues, so with sleep, your heart can be much healthier with the decrease of blood pressure.
Immune System
Consistent sleep can help a person's immune system. It can actively identify any harmful viruses and bacteria and destroy them at a faster rate compared to those who are lacking in sleep. This happens through the cytokines that are produced while the body is asleep--cytokines are the proteins that target infections and inflammation in the body.
Memory
Sleep is seen to help a person's memories become more stable and fluid. There is an active role in linking together memories in order to stabilize a person's thoughts. Information is transferred from one part of the brain onto another region.
Mood Booster
As your brain takes time to organize and recognize any factors relating to emotional information, it is important to sleep. During a person's time of sleep, the brain remembers and evaluates thoughts and memories. This allows for healthy mental processing and organization. Lack of sleep can lead the body to be consistently active and awake which promotes stress and anxiety.
Stages of Sleep
NREM2
People usually spend 50% of their sleep in this period of sleep. This part of the period of sleep usually lats 20 minute per cycle/. This is where the brain produces sleep spindle and contributes most to motor sequences and memories.
NREM3
This process is when the person falls into deep sleep. This usually lasts from 20 to 40 minutes. This process of the sleep is when a persons breathing rate drops along with their blood pressure. At this stage of sleep, a person may fall ignorant to outside noises from the environment. It is also when a persons body starts its repairs towards its tissues.
NREM1
This part of the sleeping process usually occurs after 5 to 10 minutes a person has fallen asleep. It is known to be the time where a person is in between sleep and being awake. This means that they are still aware of their surroundings and can easily be woken back up but dreams are beginning to start.
REM
There are rapid eye movements during this time of the sleeping process. A deep sleeping process where your body makes small and micro-movements. A person on average will go through 3-5 REM cycles per night which lasts up to 90 minutes in total if a person receives 8 hours of sleep. It is highly important in healthy brain development, daydreaming, emotional processing, and memory.
