A Northwestern University study on overweight and obese adults found that delaying the last meal to at least three hours before bedtime improved nighttime heart rate and blood pressure, as well as morning glucose regulation, without calorie restriction, suggesting an earlier dinner window may benefit overall cardiometabolic health—though the small, mostly female sample and lack of meal-content data limit generalizability.
An analysis of 5,899 adults aged 65+ finds insomnia linked to higher dementia risk; using population attributable fraction, about 12.5% of US dementia cases in 2022 (~449,000) could be prevented if insomnia were eliminated. However, PAF is a model, not proof of causation. Burden is higher in women and those 85+, underscoring the need to integrate sleep health into geriatric care and pursue targeted insomnia interventions.
Older adults should aim for seven to nine hours of sleep with a consistent wake time that matches their chronotype. Sleep needs can vary with activity, stress and hormones, and deep sleep tends to decline with age, but anchoring your schedule to a steady wake time helps the circadian rhythm. Some people wake earlier as they age, reflecting a shift in chronotype or personal preference. Seek medical advice if you experience persistent fragmentation, daytime sleepiness, excessive daytime sleep, snoring, or frequent nightmares.
A reader who often sleeps fewer than seven hours learns from a sleep expert that cutting sleep can carry health risks, with explanations of why even modest sleep loss matters and practical tips to improve sleep quality and duration.
A study identified five distinct sleep profiles linked to different patterns of mood, health, and brain activity, emphasizing the need for personalized approaches to improving sleep based on individual patterns and challenges.
A woman explores a new wearable device called Zeus, designed to reduce snoring by electrically stimulating throat muscles, after recording her own loud snoring habits. While initial trials show promise, her personal experience with the device was mixed, but it may help some users with snoring or mild sleep apnea, offering a less intrusive alternative to traditional treatments.
A recent study suggests that chronic insomnia increases the risk of developing dementia or mild cognitive impairment by 40%, equivalent to aging the brain by an additional 3.5 years, highlighting the importance of sleep health in cognitive aging and dementia prevention.
Addressing chronic insomnia may reduce the risk of cognitive decline and brain aging, with treatments like cognitive behavioral therapy showing promise in improving sleep quality and potentially protecting brain health.
Many adults with sleep problems do not seek medical advice, despite up to 20% experiencing chronic sleep disorders; if sleep hygiene tips like limiting blue light and bedtime routines are ineffective, it may be time to consult a doctor.
The article reviews the 11 best anti-snore pillows recommended by sleep experts, highlighting their features such as support for proper head and neck alignment, materials like memory foam and latex, and technological enhancements like sensors and adjustable firmness, all aimed at reducing snoring and improving sleep quality.
A recent Chinese study suggests a causal link between gut bacteria and insomnia, indicating that gut health may influence sleep and vice versa, potentially leading to microbiome-based treatments for sleep issues in the future.
Emerging research emphasizes that beyond just sleep duration, factors like sleep consistency, timing, and quality are crucial for cardiovascular health, prompting a broader approach to sleep assessment and intervention in cardiology.
Brent Franson, creator of the 'Death Clock' app, was shocked to learn his predicted death age was 76, with Alzheimer's as a potential cause. After making significant lifestyle changes—improving sleep, diet, and exercise—he extended his life expectancy by nine years, emphasizing that sleep, diet, and exercise are crucial for longevity and reducing Alzheimer's risk.
Frequent nightmares may indicate a higher risk of cognitive decline and dementia, according to recent studies. Research suggests that middle-aged adults experiencing weekly nightmares are four times more likely to face cognitive decline, while older adults with frequent nightmares have double the risk of dementia. The studies highlight potential early signs of dementia, especially in men, and suggest that addressing sleep disturbances could aid in early diagnosis and intervention. Maintaining social connections, regular exercise, and adequate sleep are recommended to reduce dementia risk.
