State of Consciousness: Sleep Deprivation Circadian rhythm is a regular biological rhythm with a period of approximately 24 hours and is fundamental adaptation. Circadian rhythm is associated with sleep deprivation because of many different factors. When circadian rhythms are disturbed it throws off our biological clocks and hormones, body temperatures, and digestive cycles. When you lose at least an hour of sleep every night, week after week and month after month it makes it more difficult for a person to pay attention and to remember things. It also causes the reaction time to slow down, sometimes behavior becomes unpredictable, ability to make decisions decline.
Sleep normally occurs in several stages: dreamless periods of light and deep sleep and some periods of active dreaming (REM). This cycle is repeated during the night. AS aging happens most people find it more difficult to fall asleep and stay asleep. Total sleep time may remain or is slightly decreased (6.5 to 7 hours per night). The transition between sleep and wake may be abrupt, giving older people a feeling of being more of a “light sleeper” than they were previously (nih.gov).
Light falling on the retina stimulates the production of melatonin, which keeps our body clock in time. We also have two periods of sleep-readiness - between 2pm and 6pm and 2am and 6am. Sleep patterns do, however, change as we age. As we get older we get less of stages three and four sleep. After the age of 60, we get very little deep sleep, possibly because we do not need it.
Further research by Shapiro et al studies runners sleeping patterns and found that they slept one hour more after a marathon race. This supports this theory because the more damage we do to our body the more restoration or repair is needed at night, which according to Oswald occurs in NREM sleep. On the other hand Horne challenges this view. He believed that not all sleep was necessary. He believes that REM sleep repairs and restores the body and brain, however NREM sleep (stages 1-4) is ‘optional’ sleep.
Let’s face it, it’s hard to get up in the morning, but we need all the time we have to get ready . That’s where the RoomRedo gets put into play. While you’re getting ready for work or school the RoomRedo is busy at making your bed and cleaning your room. It works faster than you work at cleaning up after yourself and making your bed. If you need to run an errand, the RoomRedo can clean and make your bed while you’re out.
Our core body temperature is lowest at around 4:30am and highest at around 6:00pm. These temperature changes also entrain the sleep-wake cycle, with low temperatures signalling a time for reduced activity. This may explain why (most of us) are fast asleep at 4:30am when our core body temperature is lowest. Hormone production also follows a circadian rhythm. Cortisol is a hormone which makes us feel alert.
What is Sleep Apnea Sleep apnea is a common sleep disorder in which you have one or more pauses in breathing while you sleep. Is a chronic disorder that affects your quality of sleep. Sleep apnea is one of the leading causes of daytime sleepiness increasing the risks of automobile accidents. Deprives you of a restorative sleep you need to be energetic and mentally sharp the next day. How you can help?
This can affect their lives vastly because sleep affects everything you do. Scientists have directly related teenagers average sleep to how well they do in school, how well they build relationships and how they feel in general. Sleep also locks in information and memories from the previous day. So if teenagers aren’t getting enough sleep, the information and memories will not be stored properly which puts their learning at risk if they are not able to fully remember information that was taught in previous days. Our bodies run on an internal clock, which is known, in scientific terms as a circadian rhythm.
They tend to retire to bed around 1 a.m. and start their day at 7 a.m.., but may be woken up to deal with emergencies in the middle of the night. Finally, full-time mothers, especially those with young children, tend to sleep when their babies do. Typically, they will sleep from 10 p.m. and be awoken at 1 a.m. to comfort their babies for a couple of hours. They then go back to bed to wake at 6 a.m., but nap for two hours or so in the early afternoon. Thus the influence on one's sleep pattern is worthy of consideration when choosing an
The clock cycles around a 24 hour time period, and is best regulated when usual routines are followed, most importantly when we wake up. When people interrupt their normal schedules as to work an unusual late shift, or in this case to just stay up late, the circadian rhythms are thrown off course. Once off course, the circadian rhythms are unable to quickly adapt to a rapidly changing activity schedule, and ends up resulting in a lack of sleep. My friend’s poor decisions are throwing his rhythms off schedule, and are affecting his deprivation of sleep throughout the rest of the week. 2) Sleep is prompted by natural cycles of activity in the brain and consists of two basic states: rapid eye movement sleep and non-rapid eye movement sleep, which consists of stages 1 through 4.
