Stages of Sleep Deprivation You Need to Know

Posted on 31 views

What are the stages of sleep deprivation?. We know that there are four stages of sleep deprivation: Non-REM (NREM) sleep stages 1,2, 3 and REM sleep. The awake period occurs before and intermittently throughout various stages of sleep deprivation  or when a person shifts to sleep position.

Stage 1 is often determined by the presence of slow eye movements, this sleepy sleep stage can be easily disrupted which causes awakenings or arousal. The tone of the muscles in the whole body relaxes and brain wave activity begins to slow since waking up.

Stage 2 is the actual NREM sleep stage specified. Resurrection or arousal does not occur as easily as in Stage 1, sleep and slow-moving eye rolls are stopped. Brain waves continue to slow down with a specific explosion of rapid activity known as a sleep spindle mixed with a sleep structure known as the K complex.

Stage 3 is known as NREM deep sleep. Awakening or arousal is rare and it is often difficult to wake a person in Stage 3 sleep. Parasomnias (sleep walking, sleep talking or somniloquy and night terror) occur during the deepest stages of sleep.

Stages of sleep deprivation by day

There are some stages of sleep deprivation by day. First, at 24 hours sleep-deprivation can disrupt coordination, memory, and Scott Kelley’s assessment. A 10-year Army veteran, knows about sleep deprivation. With lots of placement under his belt, Kelley has many instances of awake more than 24 hours in the field.

Kelley’s military training and the adrenaline-filled environment seemed to be enough to keep him focused and alert at this early stages of sleep deprivation.

At 36 Hours: Physical Health Starts to Have bad impact and be aware because your health is at risk. When you are high levels of inflammatory markers, that will cause cardiovascular disease and high blood pressure. These hormones are affected – your emotions can be everywhere.

As soon as Kelley reached 36 hours without sleep, her head began to buzz as if she was dehydrated, and she began to lose motivation. The response depends on the training, and in some cases, it works on autopilot and loses time. Once, he was called back to work right when he would go to bed after 36 hours at work, he said.

At 48 Hours: Micro Sleep and Disorientation. After two days of not sleeping, said Cralle, the body begins to compensate by closing it to micro-sleep, episodes that last from half a second to half a minute and usually followed by periods of disorientation. “People who experience deep sleep fall asleep regardless of the activities they live in,” he said. Microsleeps are similar to blackouts, and someone who experiences them does not realize that it happened.

Kelley experienced micro sleep during this phase of sleep deprivation. “About 48 hours or more, sometimes my mind starts to be neutral, and I find myself staring into the distance if I don’t maintain focus,” he described.

At the another step, 72 Hours have a different case because it will be the main Cognitive Deficit and Hallucinations. In this level will have high interference such as motivation, perception, other mental processes, deficit concentration and so forth.

Kelley gives some sample such as when someone on guard duty and repeteadly see another person with a gun in the forest, and ready to come into the camp. And after that, the person decided that he is staring at the branches and shadows. Yah, something like that the effect of sleep deprivation.

Actually stages of not getting enough sleep. But at least, knowing the stages of sleep deprivation, you can diagnose your body when you sleepless then fix your problem.
