Some factors that are associated with interrupted sleep and, therefore, may affect your sleep stages include:. Any time you have trouble falling asleep or staying asleep at night, your sleep cycle will be affected. As your body progresses through the four stages of the sleep cycle, it transitions through different biological processes that affect your temperature, your breathing, your cells, and your muscles. All the while, your brain is busy forming, organizing, and storing memories. Over time, not getting enough sleep and cycling through the four stages as you should can cause health issues and difficulty with the following:.

It's important not just to get seven to nine hours of sleep per night, but to ensure it's uninterrupted, quality sleep that allows your body to benefit from each of these four stages.

These areas include the thalamus , hypothalamus , basal forebrain, pineal gland , and portions of the brainstem. When a person sleeps is determined by the interaction of their bodys circadian rhythm and sleep homeostasis. The circadian rhythm acts as the bodys internal clock and is controlled by circadian oscillator cells in the suprachiasmatic nucleus of the hypothalamus. It roughly corresponds to a 24 hour cycle, although it is affected by external light and temperature.

Sleep homeostasis, or sleep drive, determines the length of wakefulness and the intensity of sleep when it occurs. Although the exact mechanism controlling this drive is poorly understood, it is thought to be related to the release of the neurotransmitters GABA and adenosine from the basal forebrain and other surrounding areas. Although the thalamus, basal forebrain, and brainstem promote wakefulness through release of stimulatory hormones , the hypothalamus in particular drives the awake state with hormones such as glutamate, histamine, and orexin. However, as the time for sleep approaches based on the circadian rhythm and sleep drive, these hypothalamic signals decrease to allow sleep to begin.

The central autonomic system and the pineal gland are also influenced by the sleep drive to appropriately affect the sympathetic and parasympathetic nervous systems for the changes in bodily functions seen during the stages of sleep. All stages of sleep are important and your body naturally regulates your sleep cycles to make sure you get what you need. Tools like the Oura Ring can help you monitor your sleep patterns and generate a Sleep Score each night to help you improve your sleep.

We all have those days when we just need our coffee. However, taking a look at your nightly patterns and acting on your desire to improve your sleep can help you face those days well rested. The amount of each phase of sleep can vary significantly between nights and individuals. During an ideal nights sleep, your body has enough time to go through four to five minute cycles that sample different phases of sleep as the night progresses.

In general, each cycle moves sequentially through each stage of sleep: wake, light sleep, deep sleep, REM, and repeat. Cycles earlier in the night tend to have more deep sleep while later cycles have a higher proportion of REM. This period of sleep lasts around five to ten minutes. Stage two is the second stage of sleep and lasts for twenty minutes. The brain begins to produce bursts of rapid rhythmic brain activity known as sleep spindles. The body temperature starts to decrease and heart rate begins to slow. Stage three was previously divided into stages three and four. However, sleep is the period of time in which the brain becomes extremely active. There are four stages of sleep that our bodies go through each night.

During each of these stages specific parts of the brain complete tasks that will help to improve our daily lives. There are several parts of the brain that are active while we sleep and each part performs a specific job. During the time of which we spend sleeping, there are eight main parts of the brain that start their day of work. This stage lasts five to ten minutes and sleep during this stage is relatively light. During this time our heartbeat, breathing, and eye movements decrease.

Our muscles begin to relax and occasionally twitch as well. The brainwaves at this time also begin to slow from their normal daytime patterns. The waves become very uniform and are typically categorized as alpha and theta waves. When we enter stage two non-REM sleep our breathing and heartbeat slow even more, along with the muscles relaxing even more than in stage one. At this time our body temperature decreases and eye movements come to a complete stop.

The activity of brain waves during this time decreases, but is interrupted at times by small bursts of electrical activity that are very rapid. Sleep specialist refer to these small bursts as sleep spindles. Stage two of non-REM sleep is the stage that is repeated the most throughout the night and it lasts for about ten minutes each time. Stage three non-REM sleep is the stage in which deep sleep occurs. This stage lasts for approximately thirty minutes, but takes a longer time to complete during the first half of the time we spend sleeping.

During this stage our …show more content… One of the most common brain activities during sleep is dreaming. Scientist still to this day do not fully understand why we dream or what dreams are exactly. Dreaming causes the brain to become very active, and not only at displaying the images we see during our dreams. A major part of the brain activity that takes place during dreaming is temporarily paralyzing our muscles.
