Do you feel sluggish, apathetic and sluggish? Do you have mood swings – are you subdued or short-tempered? At work, do you find it difficult to gather your thoughts, concentrate, create something creative and finish on time? Are you more hungry for fatty and high-carbohydrate products?
Did you know that the above symptoms may be a symptom of lack of sleep.
How important is proper sleep for the body?
Scientific research results:
“Scientists from the Universities of California, Pittsburgh and Carnegie Mellon (USA) proved that adequate sleep is essential to good health. Short sleep lowers the body’s immunity, increasing the risk of contracting a common viral infection several times. People who typically slept less than 6 hours a night were 4.2 times more likely to develop an infection than those who slept at least 7 hours. For people who got less than 5 hours of sleep, the risk was 4.5 times greater.”
“Seven or more hours of sleep increases the benefits your heart receives from a healthy lifestyle – suggest research reported in the “European Journal of Preventive Cardiology”. In the case of people leading a healthy lifestyle – exercising, eating healthily, drinking alcohol in moderation and not smoking – the risk of cardiovascular disease decreased by 57%, and the risk of death due to stroke or heart disease – by 67%. However, adequate sleep (seven or more hours a day) turned out to be even more important – thanks to it, a healthy lifestyle significantly more effectively protected against heart disease and stroke (the risk of disease decreased by 65% and the risk of death – by 83%).“
“Sleeping less than 6 hours a day can disrupt your appetite and cause obesity – reports the American Journal of Human Biology. Dr. Knutson has collected data from experimental and observational sleep studies. It follows from them that Sleeping less than six hours a day leads to an increase in body mass index (BMI), which is an indicator of overweight and obesity. Too little sleep disrupts the secretion of ghrelin and leptin, which increases appetite and disturbs the feeling of satiety. As a result, a sleep-deprived person eats more and moves less.”
“Research conducted in 2007-2009 by the team of Prof. Susan Redlin from Harvard Medical School included 784 men over 65 years of age. At the beginning of the study, none of them had hypertension, at the end 243 men suffered from it. It turned out that men whose deep sleep was the shortest were 84 percent more likely to have high blood pressure than those who slept deeply the longest. “Hypertension increases the risk of heart attack, stroke and other health problems.”
“People who are deprived of sleep for a long time look less healthy and attractive than those who are rested – confirmed by Swedish research, the results of which are published by the British Medical Journal. Scientists from the Karolinska Institutet in Stockholm decided to verify the common belief that sleep adds beauty. For this purpose, two photos were taken of each of the 23 young volunteers – men and women – one after eight hours of sleep and the other after 31 hours of wakefulness. All photos were taken in a standard way – from the same distance, without makeup and with the same facial expression. Those who lacked sleep were rated as less attractive and in poorer health“
“During sleep, the brain is cleansed of toxins produced during intense mental work – say American scientists in Science. A team of specialists from the University of Rochester Medical Center believes that one of the main reasons we need sleep is to cleanse our brain. Scientists have shown that during sleep, brain cells shrink and the gaps between neurons open, allowing toxins to be washed out by the fluid. If the brain cleansing process is disturbed, disturbances in its functioning may occur – as in Alzheimer’s disease, in which pathological proteins accumulate in the brain.
“People who sleep less than 6 hours a day have an increased risk of premature death – results from Italian-British research reported by the magazine “Sleep”. The analysis revealed that people who slept less than 6 hours each night were 12 percent more likely to die prematurely than people getting the recommended 6-8 hours of sleep.”
“..one extra hour of sleep a day reduces the risk of developing coronary atherosclerosis – writes “New Scientist”. A five-year study involving 495 people aged 35 to 47 found that sleep largely reduces the risk of coronary artery calcification. Calcium deposits in the arteries are a precursor of coronary heart disease. Vein calcification occurred in 27%. people who slept less than 5 hours at night, 11 percent people sleeping from 5 to 7 hours and only 6 percent people sleeping more than 7 hours“
“A healthy night’s sleep is the best way to strengthen your memory. …sleep strengthens connections between nerve cells in the brain, which is crucial for learning and memory processes – writes the BBC online service. Research by scientists from the University of Geneva on this topic was presented at the conference of the Federation of European Societies for the Study of the Nervous System (FENS).”
“The lack of a deep sleep phase leads to the development of insulin resistance, which promotes obesity and may lead to type II diabetes – reports the journal Proceedings of the National Academy of Sciences.
1 capsule 30-60 minutes before bedtime. To regulate sleep related to changes in time zones – 1 capsule 30-60 minutes before going to bed on the first day of travel and for the next few days after arriving at the destination.
