The dangers of sleep deprivation: damage to the immune system and the biological clock
The Saudi Ministry of Health and a group of medical experts confirmed that the harms of sleep deprivation are not limited to fleeting feelings of fatigue and daily tiredness, but extend to being a serious indicator that may foreshadow chronic diseases such as diabetes, high blood pressure, and cardiovascular diseases. The Ministry explained that insufficient sleep is directly linked to decreased concentration levels, mood swings, and a weakened immune system, making getting enough sleep regularly a fundamental pillar for improving mental performance and supporting both mental and physical health.
Medical awareness of the importance of sleep has evolved throughout history
Throughout history, humans have instinctively recognized the importance of rest, but a precise scientific understanding of the mechanisms of sleep has only emerged in recent decades. Historically, sleep was viewed as merely a state of physical inactivity, but modern medical research has proven it to be an active, complex, and vital biological process for human survival and cell regeneration. In this context, and with the increasing pace of life and daily pressures, the urgent need to highlight this issue has become apparent, culminating in the establishment of World Sleep Day, observed annually on March 13th. This global event aims to remind us that good sleep is not simply a dispensable luxury, but rather a critical health necessity closely linked to an individual's quality of life and longevity.
The overall impact of the harmful effects of sleep deprivation, both locally and internationally
The harms of sleep deprivation extend beyond the individual, impacting societies and economies at both local and international levels. Regionally and globally, statistics indicate that sleep disorders cost countries billions of dollars annually due to decreased productivity, increased workplace accidents, and fatal traffic accidents. Locally, health authorities are making concerted efforts to raise awareness about "sleep hygiene." The Ministry of Health has offered a set of key recommendations, including maintaining a consistent sleep and wake schedule, creating a quiet and dark sleep environment, avoiding stimulants in the evening, and ensuring regular physical activity to guarantee quality rest.
Electronic screens and disruption of the biological clock
Sleep specialist Dr. Mishni Al-Saeed explained that modern lifestyles and the excessive use of electronic devices before bedtime directly disrupt the body's circadian rhythm. The blue light emitted from screens sends false signals to the brain, suggesting it is daytime, which inhibits the secretion of melatonin, the hormone responsible for regulating sleep. This disruption delays the natural sleep cycle and keeps the mind in a state of forced wakefulness instead of deep relaxation. Among the most common sleep disorders resulting from this are insomnia, sleep apnea, and restless legs syndrome.

The risks of sleep deprivation on immunity and brain health
For his part, Dr. Yousef Al-Qurashi, Assistant Professor and Consultant in Respiratory Therapy and Sleep Disorders, stated that sleep deprivation weakens the production of protective cytokines, making the body more susceptible to chronic diseases and infections. On a mental level, lack of rest leads to the accumulation of toxins in the brain, increasing the risk of depression and anxiety, and accelerating the decline in memory and concentration in the long term.

Reasons for consulting a specialist doctor
It is advisable to consult a doctor if you experience persistent symptoms such as severe snoring accompanied by sleep apnea, or excessive daytime sleepiness that threatens your well-being. If insomnia persists for three months, occurring at least three times a week, medical intervention becomes necessary. The message from health professionals is clear: the quality of your day is built on your nights, and investing in sleep is a true investment in your mental and physical health.
