Recent studies highlight the significant relationship between sleep and brain health, with experts urging UAE residents to prioritize quality sleep to slow brain ageing.
Alexandra Zatarain, Co-Founder of Eight Sleep, explained that in regions like the UAE and GCC, where irregular sleep patterns are common, it’s crucial to focus on adequate sleep for long-term brain health. “Prioritizing sleep isn’t just a luxury; it’s an investment in longevity,” she said. A survey found that 40% of UAE residents sleep less than six hours a night, often due to stress.
A study by the University of California, San Francisco, found that poor sleep can add nearly three years to brain ageing in people in their 40s. Participants with multiple sleep issues had brains that were, on average, 2.6 years older than those with fewer sleep problems.
Health Risks of Poor Sleep:
- Cognitive Decline: Dr. Rajesh Chaudhary, a neurologist at Aster Hospital Sharjah, warned that insufficient sleep accelerates cognitive decline and raises the risk of neurodegenerative diseases. During deep sleep, the brain performs restorative tasks like synaptic pruning, essential for maintaining cognitive health.
- Overall Health: Dr. Humam Schakaki, Consultant Pulmonologist at Burjeel Medical City, explained that sleep is crucial for muscle growth, immune system support, and emotional regulation. Inadequate sleep impairs alertness, judgment, and weakens immunity.
Improving Sleep Quality:
- Consistency: Dr. Chaudhary recommended a consistent sleep schedule to regulate the body’s internal clock. A sleep-conducive environment (dark, quiet, cool) is essential.
- Reduce Blue Light: Exposure to blue light from screens in the evening can suppress melatonin. Avoiding screens and engaging in calming activities like reading or meditation before bed helps prepare the body for rest.
- Avoid Stimulants: Caffeine and nicotine can disrupt sleep, and regular exercise, done earlier in the day, supports restful sleep.
Case Studies:
- A young male patient with high blood pressure was found to have obstructive sleep apnea. After using a CPAP machine, his blood pressure normalized without the need for medication.
- A 50-year-old female patient with Restless Leg Syndrome (RLS) was treated with medication and sleep hygiene improvement. After a few weeks, she reported better sleep quality and reduced daytime fatigue.
The Power of Good Sleep:
Alexandra Zatarain pointed out that research involving Eight Sleep’s specialized pods showed that improving sleep quality can lead to significant health benefits, including cardiovascular improvements similar to those from exercise. By focusing on improving sleep, individuals can influence their health and wellbeing, ensuring better daily functioning and long-term health protection.
