During stage two, the brain waves begin to slow. Short periods of rapid brain wave activity, called sleep spindles, occur throughout the 20 minute period. The body temperature starts to drop and the heart rate slows, as well as the breathing. Extremely slow delta waves emerge in the third stage. They are interspersed with smaller, faster waves and instigate the transition from a light sleep to a very deep sleep.
Stage one, called light sleep, lasts about five minutes. Stage two, or the onset of sleep, last thirty to forty minutes. During stage one and stage two, your brain waves slow, and your heart rate and body temperature drop. People can easily wake during these stages. Stage three and stage four are deep-sleep stages.
Adults Sleep Young adult gets full and restorative sleep. In their early twenties, you get Stage III sleep, which is the deeper and most restorative. After your early 20s, you spend more of the night in Stage II sleep, or middle sleep, which is mildly restorative. As you get older, your sleep becomes less satisfying and less restorative. And, in the fast pace of life, it means adults are sleeping less than before.
Sleep deprivation takes a toll on these students physically, academically and emotionally. Schools during the mid-twentieth century began around nine o'clock in the morning (Crelin 1). The creation of bus schedules led to earlier school start times during the latter half of the twentieth century and now some schools start as early as 7:20 a.m (Crelin 1). It is important to understand how sleep works in order to understand how a lack of it causes damage to the body. While we are awake, neurotransmitters keep us focused.
Nordio and Romanelli (2008) reported that acupressure band at HT 7 for 10 hours, daily for 20 days improved sleep and normal melatonin rhythm compared to the control group in 33 patients (p < .05 and p= .01 respectively). Harris and colleagues (2005) investigated the effect of 2 sequences of acupressure treatment (cross-over design) to support relaxation or stimulation administered daily for 3 days. These investigators found that acupressure at LI 4, ST 36 KD 1, and UB 10 decreased fatigue and improved alertness compared to the period of relaxation acupressure in 39 healthy university students. Molassiotis and colleagues (2007) reported that acupressure for 3 minutes daily for 2 weeks improved fatigue compared to the control group (p< 0.05). However, there was no statistical difference between acupressure treatment and placebo (acupressure at nonacupressure points) groups.
After a long research we have come to a conclusion that basic lifestyle changes would benefit while protecting your heart. Sleep is top of my list. A lot of us have insomnia in this era, either we are thinking to much or not managing our daily rhythm perfectly. In the last 50 years overall sleep duration has decreased on average of 1.5 to 2 hours per night per. In a meta-analysis that was published in the European Heart Journal, presented that short sleepers had a 48% increased risk for coronary heart disease.
However, the scope of this project was to focus on the task-related factors associated with low workload therefore these other factors are only briefly discussed below. The individual factors associated with low workload include sleep-related fatigue and circadian rhythms. Broadly speaking, lack of sleep enhances the effects of low workload situations as it can reduce arousal levels. Williamson, Lombardi, Folkard, Stutts, Courtney and Connor (2011) conducted a review on fatigue and performance and defined sleep-related fatigue as fatigue caused by a ‘reduction in the quantity or quality of sleep, or extension of the time awake since sleep’ and this produces ‘a homeostatic drive to sleep’, which is often experienced as sleepiness. Circadian rhythms are the 24 hour sleep-awake cycle that humans experience.
When you decide to sleep on the floor, you can finally enjoy your peace and save your hard earned money for something else. What’s the difference between a hard mattress and the floor anyway when you know the soft one will have you sleeping in hunched up position? Cons MD Health2 doctors do warn for you to be ready to face the discomfort you are bound to experience during the first few times of sleeping on the floor especially if you are overweight. You can make yourself comfortable by using a pillow then get rid of it as you get accustomed to it. Although sleeping on your back is recommended Natural Sleep Foundation3 cautions that this position may cause the tongue to block the breathing tube, making it a dangerous position for people suffering from sleep apnea.
Stay away from using your electronics or drinking alcohol or caffeine. Using these tips your body will fall naturally into a sleep schedule. In conclusion, sleeping is an important part of our life without it we could die. A study shows that we can spend 11 days without sleep but, with all the side effects you just read about do you think that it is reasonable to stay awake. One thing I found very interesting is that you can start getting hallucinations if you do not get enough
Sleep well Sure you know you need 8 hours of sleep each night (or at least more than 6 hours, if you have difficult times). But rather than quantity, you should notice the quality of your rest.
