A new study highlights that inconsistent sleep schedules going to bed and waking up at different times daily—can raise the risk of stroke, heart attack, and heart failure by 26%, even if you get a full night’s sleep.
The study, published in the Journal of Epidemiology and Community Health, is the most detailed of its kind, linking irregular sleep patterns with serious heart health issues. Medical experts recommend maintaining a consistent schedule for better well-being.
Expert Opinions
Doctors in the UAE pointed out that earlier research focused mainly on sleep duration, suggesting 7 to 9 hours of sleep per night for optimal health. However, this study revealed that regularity is just as important.
Inconsistent sleep can disrupt the body’s internal clock, or circadian rhythm, leading to increased levels of stress hormones, high blood pressure, and inflammation, all of which affect heart health.
Professional Challenges
For many UAE residents, sticking to a regular bedtime can be tough due to demanding work schedules, especially for those with night shifts or rotating hours. Jad Azar, a Lebanese expat in the hospitality industry, shared his struggles.
“Some days feel like a blur. My body is exhausted, but my mind races with work demands,” said the 32-year-old. “In the hotel industry, long, unpredictable hours make consistent sleep a luxury. Even when I sleep, my mind won’t shut off because of the responsibilities and expectations, especially during peak seasons.”
Despite the challenges, Jad stays motivated by valuing hard work and dedication. “These are the years to push myself and go the extra mile,” he added.
Travel and Family Commitments
Balancing work, travel, and family life also disrupts sleep for many. Arijit Nandi, an Indian expat, explained how his hectic routine affects his rest.
“My business trips involve early morning flights, often requiring me to wake up in the middle of the night. Add late-night presentations and board meetings, and my sleep schedule becomes chaotic,” he said.
As a father, Arijit also spends late nights caring for his child when needed. Despite his busy schedule, he enjoys dropping his son off at school every morning. “It’s part of my routine, and I wouldn’t trade it,” he shared.
The Health Impact
Doctors warn that irregular sleep can lead to serious health problems. Dr. Ahmad Alkasmi from Aster Hospital Sharjah explained how a disrupted circadian rhythm increases stress hormone levels, raising blood pressure and inflammation. Over time, this damages blood vessels and elevates the risk of heart disease.
Irregular sleep also worsens conditions like high blood sugar, cholesterol issues, and metabolic disorders, including diabetes and obesity. Dr. Basma Mohamed Aly El Nager from Burjeel Medical Centre highlighted that South Asians, already at higher risk for heart diseases, may face even greater challenges with inconsistent sleep.
Take Action for Better Health
Experts stress the importance of recognizing the role of sleep in heart health. Regular bedtime routines, even in fast-paced lifestyles, can make a significant difference. Those experiencing ongoing sleep irregularities should consult a healthcare provider to identify potential causes and improve their overall well-being.
Maintaining consistent sleep habits isn’t just about feeling reset, it’s essential for your heart and overall health.
