That sleep is one of the greatest pleasures in life, we all know. Can wake up late, no time to worry is a delight, but for most this is only possible in the few days off. However, sleep well does not necessarily mean splash about to sleep or stop doing the tasks to succumb to laziness, but maintain a good sleep routine to face the day to day stressful. Besides the pleasure, science proves that sleep well only brings benefits to your health and well-being – which goes for people of all ages, from children to elders.
A good night’s sleep has to do with living longer, according to a study by University of Warwick and the University Federico II in Italy. According to the researchers, people who sleep less than six hours or more than eight per day is 12% more likely to die. With the quality of impaired sleep, grow rich accidents due to drowsiness, and heart attacks due to the stress.For the neurologist Renato Ferraz Lima, the ideal amount of sleep varies from person to person. “But the minimum recommended is six hours a day, it is important not to exceed nine adults because those who sleep more than it ends up actually less rested,” explains the expert. The importance of sleep, also extends to learning. “In REM, when dreams happen, things that have been learned during the day are processed and stored. When we sleep less than necessary, short-term memory is not processed and can not turn into knowledge what has been learned,” explains the neurologist.
Renato further differentiates the types of insomnia: there is transient, having a short time and is usually triggered by an episode, intermittent, or one that passes but returns from time to time, and chronic, which is constant.
Impaired Sexual Life
For those who do not consider untimely death a good reason to worry about sleep itself, will this: men who sleep poorly are more likely to have erectile dysfunction. The study, of the Sleep Institute, was done with 449 men aged 20 to 80 years. Poor sleep is associated with low production of the male sex hormone testosterone, according to the neurologist Renato Ferraz Lima. The study also showed that people with very fragmented sleep and shorter REM sleep (stage in which dreams occur) have twice the risk of dysfunction.
Sleep x childhood obesity
Studies also point to the importance of cultivating good sleep habits from a young age. sleeping habits in childhood can be crucial to adulthood. “Parents do not pose any rules of sleep for children, creating in them the habit of sleeping late. After a few years, however, they need to wake up early to go to school or work. However, they can not sleep early because so were accustomed “says neurologist.
A study by the Research Institute of Seattle Child, USA, found that children and adolescents who do not get enough sleep are more likely to become obese. After evaluating data on sleep patterns, diet and physical activity levels of 723 young people with an average age of 14 years, experts observed a relationship of sleep with a higher body mass index (weight measure in relation to height) and a higher percentage of fat.
Another study, from the University of Helsinki and National Institute of Health and Welfare, Finland, concluded that among the 280 children participants, those who slept less than eight hours a night were more hyperactive. Experts responsible believe that adequate sleep could improve the behavior of healthy children and reduce symptoms of suffering from attention deficit hyperactivity disorder.
Because sleep problems, the child’s performance may fall and it can be diagnosed as hyperactive because of irritability and their difficulty concentrating.
An important point in the children’s sleep is the role of parents. A study by the American Academy of Sleep Medicine showed that children from families that set regrados sleep schedules develop better learning. The language development, phonological awareness and early math skills were most frequently detected in children whose parents reported having rules about what time to go to bed. In addition, sleep an hour earlier contributed to greater development measures.
The doctor says that the optimal amount of sleep for children is from 9 to 11 hours of sleep. “Children often get irritable when they sleep less than this, and have commitment to their growth, because during one of the phases of sleep there is the release of GH hormone responsible for growth.”
You and I, you and I: juntinho?
Before unusual items for sale, such as pillows in arm format to satisfy that desire the lonely sleeping snuggle with someone, you can even think that sleeping next to someone is an antidote to insomnia. But it does not always work well. A study by the University of Surrey in the UK, found that sharing a bed with your partner can cause troublesome because of snoring or dispute the blanket, and bring thus the loss of precious hours of sleep. The researchers concluded that, on average, couples suffer 50% or more problems sleeping, when sharing a bed. a link was also established between poor sleep and depression, heart disease, stroke, lung disorders, traffic accidents and divorce. “For those who divide a bed with a partner, have insomnia and bothered by snoring or ‘territorial’ dispute bed, worth trying to sleep in separate beds or environment,” says neurologist.
The quality of sleep also has a role in controlling blood pressure. A study by the University of Chicago (United States) confirms that a good night’s sleep is associated with lower levels of blood pressure. The study evaluated 578 middle-aged adults. The results showed that, after the exclusion of patients who were taking antihypertensive medication, shorter duration of sleep and the worst quality, were decisive for an increased risk of elevated systolic and diastolic blood pressure over time. A short sleep also was associated with an increased risk of developing hypertension. For every hour of sleep less, there was an increased relative risk of incidence of hypertension by 37%.
