Lack of sleep not just tiring, but dangerous, warns health expert
Sleep deprivation linked to increased risk of heart disease and mental health problems.
SHAH ALAM - Sleep disorders not only lead to nights of tossing and turning but are also associated with severe long-term health risks, including cardiovascular diseases (CVD) and mental disorders, says Universiti Putra Malaysia (UPM) Public Health Physician, Associate Professor Dr Halimatus Sakdiah Minhat.
Halimatus highlighted that poor sleep quality significantly increases the risk of hypertension, heart disease, and stroke.
"Insomnia, which includes trouble falling asleep or frequent awakenings, is considered a chronic condition if it occurs three times a week for more than three months," she told Sinar when contacted recently.
She noted that chronic sleep deprivation is linked not only to CVD but also to mental health issues such as depression and anxiety, substance abuse, a weakened immune system, cognitive decline, and a diminished quality of life.
She said it may also lead to long-term consequences like diabetes and obesity.
A recent study from Sonno, Malaysia's leading sleep company, stressed the alarming extent of sleep-related issues, which found that nine out of ten locals, or 87.2 per cent, report problems such as insomnia, frequent waking, or difficulty initiating sleep.
The study surveyed 212 people across Malaysia last January.
Halimatus also pointed out the immediate impacts of sleep disturbances, including extreme fatigue, emotional disturbances, and reduced cognitive abilities, manifesting in forgetfulness, lack of focus, and decision-making difficulties.
"Those suffering from chronic insomnia experience significantly lower energy levels throughout the day, often accompanied by headaches, dizziness, or muscle weakness," she added.
Prolonged sleep deprivation can lead to severe emotional instability.
"Individuals with insomnia are five times more likely to develop depression than those without sleep issues," she said, emphasising the profound effect insomnia has on memory, concentration, and overall performance.
