The first stage of sleep lasts for about 5-10 minutes as you are falling asleep. It is like a transition period. The brain produces theta waves during this time, which are slow brain waves. Your heart rate noticeably slows down. Hallucinations are commonly found in this stage.
In stage 1, the heart beat slows down, muscle tension is reduced and alpha waves are replaced by slower theta waves. Stage 2 sees the emergence of irregular bursts of electrical activity known as ‘sleep spindles’; at this stage we are ‘properly’ asleep. In stage 3 there are very slow waves with large amplitude. This is the first stage of deep sleep. During this stage, heart rate and body temperature continues to fall.
Day 5: Patient’s heart rate would increase rapidly when he gets out of bed but would decrease rapidly back to normal. Patient was still in A. fib. Continue to monitor heart rate and continue therapy, ready for a TEE today. There were no complications with the TEE patient was shocked back into normal sinus rhythm. S: Patient is having shortness of breath and feels a little weak.
By the age of 6 months a circadian rhythm is established and by the age of 1 year infants are usually sleeping mainly at night, with 1 or 2 naps during the day. The periods of deep sleep lengthen and there is a reduction in the amounts of active/REM sleep. Sleep patterns change during childhood and by the age of 5, children have EEG patterns that look like those of an adult but they are still sleeping more (around 12 hours a day) and having more REM activity (about 30% of total sleep time). Boys are also found to sleep slightly more than girls. As childhood progresses, the need for sleep decreases, but in adolescence it increases slightly, to around 9 or 10 hours a night.
Outline and evaluate one or more biological rhythms (12 marks 4+8) An Ultradian rhythm is a biological rhythm that spans less than 24 hours such as the basic rest- activity cycles or the stages of sleep. Sleep consists of five stages and one cycle through these stages lasts for about 90 minutes. The first four stages are known as NREM sleep (non-rapid eye movements) and the fifth stage is called REM sleep (rapid eye movement) Stage one and two are characterised by a relaxed state. EEG shows alpha and theta brain waves during these stages and heart rate slows and temperature drops. Stage 3 and 4 also known as slow wave sleep (SWS) is characterised by delta brain waves, during these stages most of the body’s repair work is undertaken.
Reduced sleep can add manic and hypomania episodes. Studies have found that 25% to 65% of bipolar patients who had a manic episode have experienced social rhythm disruption prior to the episode [ (AstraZeneca, 2009) ]. Social rhythm disruption can throw off a person’s sleeping cycle. This can be as simple as staying up late working, watching television or even being nervous about something and not being able to sleep. Once a person lacking sleep has gone into mania they start believing that they do not need sleep and will stay awake for more than 20 hours, this makes the disorder worse [ (AstraZeneca, 2009) ].
This is the state in which they can be a threat to themselves or others. The next stage is the crash in which the user’s body cannot handle the drug anymore and will shut down into a sleep for 3 to 5 days. After the crash, a hangover of hydration and exhaustion starts, lasting for weeks. The user will feel weak, falsely leading the user to turn back
When you eat, your body automatically turns any calories it doesn’t currently need into triglycerides and stores it in your fat cells to use for energy in between meals. If you eat more calories than you burn on a regular basis, then you are at a high risk for your
Experimental Research PSY/285 February 17, 2013 Experimental Research Pharmaceutical Research: Sleeping Aids There are many different kinds of sleeping aids that can help someone fall asleep today. Insomnia is when a person has a hard time falling asleep, staying asleep, or a disturbance in the quality of sleep a person gets that will make them feel they are not well rested when they do wake. Insomnia is more common today then we think, about 10% of adults suffer from severe insomnia. Lack of sleep may cause someone to have no motivation, mood swings, and not be able to function to their full potential. Insomnia has also been known to cause depression, anxiety, and stress, which in turn can cause other health problems.
Trinh Le Larry Bounds AP Language and Composition 26 August 2014 Amount of Sleep Required Everybody goes through a 24-hour cycle for each and every day. Within those 24 hours people can choose to be lazy, active, productive, adventurous, studious, or even curious. No matter what the answer is, one thing we all have in common is that we all need sleep. Sleep is a condition when our body and mind recurs for many hours every night, in which the body system is inactive and relaxed. Therefore, after a long day of doing nothing or work, the human body has to be fatigued and needs rest or even better the body and mind needs sleep.
