A weak body clock may be an early warning for dementia
New research shines a spotlight on the profound link between our internal biological clock and the risk of developing dementia. Published in late 2025 in the journal Neurology, the study reveals that weakened and irregular circadian rhythms, our body’s natural 24-hour cycles, may significantly raise the chances of dementia in older adults. Led by Dr. Wendy Wang from UT Southwestern Medical Center, the research tracked over 2,000 participants aged around 79 for three years, clearly showing that disrupted body clocks more than doubled the risk of developing dementia.
But what does this mean for you? The study not only emphasizes the importance of maintaining strong circadian rhythms but also invites us to re-evaluate how lifestyle choices, food, and even dining times might influence brain health. By understanding the body clock’s role in dementia risk, individuals can take practical steps to support a healthier and more synchronized rhythm.
How Does a Weak Body Clock Raise the Dementia Risk?
Our circadian clock regulates crucial aspects of health, including sleep, hormone production, digestion, and brain function. A “strong” body clock aligns well with a predictable day-night cycle, supporting regular patterns of rest and activity. However, when this rhythm becomes weak, irregular, or fragmented, it disrupts these processes. For instance, sleep becomes less restorative, and the brain struggles to clear amyloid proteins, a hallmark of Alzheimer’s disease.
The researchers noted that participants whose daily activity levels peaked later in the afternoon were at a 45% higher dementia risk compared to those who peaked earlier. This suggests that not only the strength but also the timing of your body’s internal rhythm could play a pivotal role in brain health.
What Foods Can Support a Healthy Circadian Rhythm?
Nutrition plays an essential role in maintaining a strong body clock. Certain foods are known to directly support circadian health by influencing sleep quality, energy metabolism, and overall biological rhythms. Here’s a breakdown:
- Magnesium-rich foods: Leafy greens like spinach and kale enhance sleep and support balanced energy levels.
- Omega-3 fatty acids: Found in salmon, walnuts, and flaxseeds, these support brain function and reduce inflammation.
- Complex carbohydrates: Whole grains provide steady energy that aids in synchronized daily activity patterns.
- Tryptophan sources: Turkey, eggs, and lentils promote serotonin, aiding sleep and mood regulation.
- Melatonin-rich foods: Cherries and bananas help support natural sleep-wake cycles.
By eating nutrient-dense and Mediterranean-style meals, which emphasize whole foods over processed ones, you can naturally nurture your body clock. Maltese cuisine, with its rich use of fresh vegetables, fish, and olive oil, is a shining example of a diet that aligns well with circadian health.

Tips for Strengthening Your Body Clock
- Stick to a schedule: Wake up, eat, and sleep at the same times daily.
- Maximize natural light exposure: Spend time outdoors, especially in the morning, to set your body clock.
- Restrict artificial light: Avoid screen time before bed as it disrupts melatonin production.
- Eat earlier: Avoid heavy meals late at night to prevent biological rhythm interference.
- Exercise regularly: Physical activity during the day reinforces your natural activity-rest cycles.
Why Food and Rhythms Go Hand-in-Hand
Emerging research continues to show the deep connection between what we eat, when we eat, and how it aligns with our body’s natural rhythms. Beyond the nutrients themselves, the timing of meals can either support or weaken our circadian clock. Align your meal timings to coincide with your most active daylight hours, and avoid eating late at night when your digestive system naturally slows down.
By incorporating these principles into your daily routine, not only can you enhance overall health, but you may also reduce your risk for neurodegenerative conditions like dementia.

FAQ: A Weak Body Clock and Dementia Risk
How does a weak body clock increase the risk of dementia?
Weak or irregular circadian rhythms disrupt the body's natural processes, including sleep, hormone production, and brain function. This disruption limits the brain’s ability to clear harmful amyloid proteins, which are linked to Alzheimer's, and can impair memory and cognitive function over time. Research published in Neurology in 2025 found that weak body clocks more than doubled the dementia risk for older adults. Specific findings showed that participants whose energy peaked later in the afternoon instead of earlier experienced a 45% higher likelihood of developing dementia. This emphasizes the role of both rhythm strength and timing in brain health. Strengthening your body clock through consistent sleep, exercise, and meal timings while avoiding late eating could help reduce this risk. Learn more about circadian rhythms’ importance and their link to dementia at ScienceDaily.
What are circadian rhythms and why are they important?
Circadian rhythms are your body’s natural 24-hour cycle that regulates essential processes, such as sleep, digestion, hormone production, and brain activity. These rhythms align with factors like light, temperature, and eating patterns to manage your rest, wakefulness, recovery, and energy levels. If your body clock aligns with these natural cycles, it strengthens your overall well-being and reduces neurological decline risks. When disrupted by irregular sleep or erratic eating and activity schedules, circadian rhythms lose their synchronization, which weakens the brain's ability to self-regulate. In particular, poor circadian health impacts nightly processes like removing harmful proteins from the brain, a failure which has been linked to Alzheimer’s disease. Keeping your rhythms consistent and aligned with the natural daylight cycle can support overall health and potentially reduce dementia risks. Research on circadian health continues to point to the critical role these rhythms play in long-term cognitive function. Look into the details of circadian rhythm health with the latest study on Neurology here.
What can I eat to improve my circadian rhythm and decrease dementia risk?
Certain foods support a healthy circadian rhythm by enhancing sleep, energy regulation, and brain function. The following are excellent additions to your diet:
- Magnesium-rich foods: Spinach, almonds, and pumpkin seeds can improve sleep quality and balance energy levels.
- Omega-3 fatty acids: Found in salmon, walnuts, and flaxseeds, they reduce inflammation and nourish the brain.
- Complex carbohydrates: Whole grains like quinoa and brown rice offer steady energy that aligns with daily activity cycles.
- Tryptophan sources: Turkey, eggs, and lentils encourage serotonin production for better sleep and mood.
- Melatonin-rich foods: Cherries and bananas help regulate your natural sleep-wake cycle.
