The benefits of sleeping 8 hours a day for preventing chronic diseases
The importance of healthy sleep in disease prevention
A medical consultant, in an exclusive statement to Al-Youm newspaper, emphasized the critical importance of adhering to a healthy sleep schedule, noting that getting eight hours of sleep daily acts as a protective shield against many chronic diseases. This statement comes at a time when life's pressures are increasing and the pace of daily life is accelerating, leading many to overlook the importance of sleep and its direct impact on overall health and quality of life.
The scientific and historical context of the sleep process
Historically and scientifically, sleep has never been merely a state of inactivity or passive rest, but rather an active and complex biological process that the body needs to rebuild its cells and replenish its energy. During sleep, humans go through several cycles, including light sleep, deep sleep, and rapid eye movement (REM) sleep. In deep sleep, the body releases growth hormones, repairs damaged tissues, and enhances immune system functions. Accumulated medical studies over the decades have proven that chronic sleep deprivation disrupts the body's hormonal and biological balance.
How does sleep protect the body from chronic diseases?
The link between sleep deprivation and chronic diseases is now an undeniable scientific fact. Not getting eight hours of sleep is strongly associated with an increased risk of cardiovascular disease, as prolonged sleep deprivation leads to high blood pressure and increased stress and inflammation levels in the body. Furthermore, sleep plays a crucial role in regulating blood sugar levels; chronic sleep deprivation reduces insulin sensitivity, paving the way for type 2 diabetes. Disruption of the hunger and satiety hormones (ghrelin and leptin) due to lack of sleep is also a major contributing factor to obesity.
The local and global impact of sleep deprivation
Both locally and internationally, the "sleep deprivation epidemic" has become a major challenge for healthcare systems. The World Health Organization and numerous regional health bodies consistently warn of the economic and social repercussions of insufficient sleep, including decreased productivity, increased workplace and traffic accidents, and the exorbitant cost of treating resulting chronic diseases. In our Arab societies, lifestyle changes such as excessive use of smart devices before bedtime, delayed work hours, and late-night socializing have reduced the average number of hours of sleep per person, necessitating a serious effort to raise health awareness.
Tips to improve sleep quality
To maximize the benefits of sleep and strengthen the body, experts recommend following healthy sleep habits. This includes setting a consistent bedtime and wake-up time, even on weekends, creating a quiet and dark sleep environment, and avoiding caffeine and heavy meals several hours before bedtime. It's also advisable to avoid the blue light emitted from mobile phones, as it inhibits the production of melatonin, the hormone responsible for regulating the sleep-wake cycle. In conclusion, we must recognize that eight hours of sleep is not a luxury, but a fundamental pillar of health, as important as proper nutrition and exercise.
