Sleep deprivation poses hidden health risks
MUSCAT, March 23
During the holy month of Ramadhan, a shift in lifestyle and eating habits is inevitable. While fasting serves as a cleansing process for both the body and mind, many people tend to overlook the importance of maintaining adequate sleep, which can have significant negative effects on overall health and well-being.
Dr Hamed Al Sinawi, senior consultant and old-age psychiatrist at Sultan Qaboos University Hospital, explains that during Ramadhan, many people stay up late for prayers, social gatherings, or meals with family and friends. This results in reduced sleeping hours at night, often leading to exhaustion during the day.
'Studies show that sleep deprivation can cause increased fatigue, irritability, mood swings, and reduced patience, which sometimes manifests as road rage,' points out Dr Al Sinawi.
Dr Dilip Kumar Singvi, a specialist in internal medicine and diabetes at Burjeel Hospital, defines sleep deprivation as a condition where a person is either not getting enough sleep (ideally eight hours per night) or is experiencing poor-quality sleep over an extended period of time.
'One of the common causes of sleep deprivation is a disrupted sleep cycle, which is particularly evident during Ramadhan, as nighttime sleep is shortened,' he noted.
According to Dr Singvi, the effects of sleep deprivation are far-reaching. Symptoms include fatigue, daytime drowsiness, mood swings, impaired judgement, memory lapses, and headaches. He warns that prolonged lack of sleep can impact several bodily systems, increasing the risk of heart disease, high blood pressure, diabetes, obesity, and mental health issues such as anxiety and depression. Additionally, sleep deprivation can worsen conditions like obstructive sleep apnea and elevate the likelihood of car accidents.
Dr Al Sinawi stresses the importance of maintaining at least eight hours of quality sleep daily to function optimally. 'Loss of sleep affects memory, concentration, and decision-making abilities, all of which are essential for work and daily activities. Even if working hours are reduced during Ramadhan, individuals still need sharp decision-making skills. Additionally, sleep deprivation can significantly impact a driver's reflexes and reaction times, increasing the risk of road accidents.'
Some individuals attempt to compensate for lost sleep by napping during the day. However, Dr Al Sinawi warns that this may not be sufficient and could lead to further complications. 'Mental health conditions such as bipolar disorder can be at risk of relapse due to disturbances in the circadian rhythm, especially when individuals choose to sleep all day and remain awake at night. This disrupts the body's natural biological clock, leading to emotional instability.'
Experts emphasise that maintaining a healthy sleep schedule is not just about avoiding fatigue - it is crucial for long-term health. Chronic sleep deprivation weakens the immune system, making individuals more susceptible to infections and illnesses. Additionally, disrupted sleep patterns can impair metabolism, contributing to weight gain and an increased risk of diabetes. Dr Singvi advises that simple lifestyle adjustments, such as reducing screen time before bed, setting a consistent sleep schedule, and creating a restful sleeping environment, can help mitigate the negative effects of sleep deprivation during Ramadhan.
As the holy month encourages self-discipline and mindfulness, ensuring proper rest should also be a priority, allowing individuals to maintain both their physical and mental well-being while observing their spiritual commitments.
