Almost every addicted individual believes at the outset stopping using drugs without help is easy and most people try to quit without seeking treatment. Although some people are successful, many attempts result in failure to achieve permanent abstinence. Research suggests that long term drug abuse results in changes in the brain that last long after a person stops using drugs. These changes in brain function from drugs can have many behavioral consequences, including an inability to exert control over the impulse to use drugs, despite adverse consequences the defining characteristic of addiction. Understanding that addiction has a fundamental biological component may help explain the difficulty of achieving and maintaining abstinence without treatment. Psychological stress from work, family problems, psychiatric illness, pain associated with medical problems, social cues or environmental cues like encountering streets, objects or even smells associated with drug abuse, can trigger intense cravings without the individual being consciously aware of the triggering event. Any one of these factors can hinder attainment of sustained abstinence and make relapse more likely. Nevertheless, research indicates that active participation in treatment is an essential component for good outcomes and can benefit even the most severely addicted individuals.

Natural Oils

Natural oils contain hundreds of organic constituents such as hormones, vitamins and other natural elements that are beneficial to the skin. Natural oils fall into two general categories: essential oils and carrier or base oils. Essential oils are volatile compounds found in plants. They give fruits, flowers, herbs and spices their fragrance and flavor. Obtained by distillation or expression, essential oils are highly concentrated and used at a very low concentration. Carrier oils, such as almond, sunflower, olive, walnut and other oils exist in higher concentration in cosmetics and when applied directly to the skin nourish, soften and protect it. Diluting essential oils makes them good bases. Oils are highly penetrating. They easily enter through a cell wall delivering essential vitamins, oxygen and nutrients. This helps stimulate cell metabolism and the regeneration process. The ability of oils to penetrate and carry nutrients through the cell wall to the cell nucleus can prevent cell deterioration, which can lead to infections and diseases.

How Much Sleep Is Enough?

Animal studies suggest that sleep is as vital as food for survival. Rats, for example, normally live two to three years, but only live five weeks if these rats do not get REM sleep and only two to three weeks if these rats do not sleep at all. This timeframe is similar to death due to starvation. But how much sleep do humans need? To help answer that question, scientists look at how much people sleep when people can do can so without restrictions.
When healthy adults have unlimited opportunity to sleep, adults will sleep on average between eight and either and half hours a night. But sleep needs vary from person to person. Some people appear to need only about seven hours to avoid problem sleepiness whereas others need nine or more hours of sleep. Sleep needs also change throughout the lifecycle. Newborns sleep between 16 and 18 hours a day and children in preschool sleep between 10 and 12 hours a day. School-aged children and adolescents need at least nine hours of sleep a night.
The hormonal influences of puberty tend to shift the biological clocks of adolescents. As a result, teenagers are more likely to go to bed later than younger children and adults and teens tend to want to sleep later in the morning. This sleep and wake rhythm is contrary to the early-morning start times of many high schools and helps explain why most teenagers get an average of only seven to seven and a half hours of sleep a night.
As people get older, the pattern of sleep also changes, especially the amount of time spent in the deep sleep stages. Children spend more time than adults in these sleep stages. This explains why children can sleep through loud noises and why kids might not wake up when parents relocate sleeping children from the car to a bed. During adolescence, a big drop occurs in the amount of time spent in deep sleep, which is replaced by lighter, stage 2 sleep. Between young adulthood and midlife, the percentage of deep sleep falls again: from less than 20 percent to less than 5 percent, one study suggests. Lighter sleep (stages 1 and 2) replaces deep sleep. From midlife through late life, people tend to experience more interruptions by wakefulness during the night. This disruption causes older persons to lose more and more of stages 1 and 2 non-REM sleep as well as REM sleep.
Many older people complain of difficulty falling asleep, early morn­ing awakenings, frequent and long awakenings during the night, daytime sleepiness and a lack of refreshing sleep. Many sleep problems, however, are not a natural aspect of sleep in the elderly. Because older people are more likely to have many illnesses that can disrupt sleep, some sleep complaints often may be due, in part, to illnesses or the medications. In fact, one study found that the prevalence of sleep problems is very low in healthy older adults. Other causes of sleep complaints in some of older adults are sleep apnea, restless legs syndrome and other sleep disorders that become more common with age. In addition, older people are more likely to have sleep disrupted by the need to urinate during the night.
Some evidence shows that the internal clock shifts in older people, so older people are more apt to go to sleep earlier at night and wake up earlier in the morning.

Despite variations in sleep quantity and quality, both related to age and between individuals, studies suggest that the optimal amount of sleep needed to perform adequately, avoid a sleep debt and not have problem sleepiness during the day is about seven to eight hours for adults and nine or more hours for school-aged children and adolescents. Similar amounts seem to be necessary to avoid further increasing the risk of developing obesity, diabetes or cardiovascular disorders.
Quality of sleep is as important as quantity. People whose sleep is frequently interrupted or cut short may not get enough of both non-REM sleep and REM sleep. Both types of sleep appear to be crucial for learning and memory--and perhaps for all the other restorative benefits of healthy sleep, including the growth and repair of cells.
Many people try to make up for lost sleep during the week by sleeping more on the weekends. If a person has lost too much sleep, sleeping in on the weekend does not completely erase the sleep debt. Certainly, sleeping more at the end of the week does not make up for the hampered performance at the beginning of or during that week. Just one night of inadequate sleep can adversely affect the functioning of the body and mood during at least the next day.
Daytime naps are another strategy some people use to make up for lost sleep during the night. Some evidence shows that short naps (up to an hour) can make up, at least partially, for the sleep missed on the previous night and improve alertness, mood and work performance. However, naps do not substitute for a good sleep. One study found that a daytime nap after a lack of sleep at night did not fully restore levels of blood sugar to the pattern seen with adequate nighttime sleep. If a nap lasts longer than one hour, the body may have a hard time waking up fully. In addition, late afternoon naps can make falling asleep at night more difficult.
