Listen To The Episode With Dr. Sykes Here: The Daily Dose Podcast
Sleep is a fundamental part of human life, yet it remains one of the most mysterious and important parts of our well-being. In this episode of The Daily Dose Podcast I talk with Dr. Lucinda Sykes about the many complexities of sleep, from the mind to the brain and the chemicals in between.
As we get older, sleep challenges can become more pronounced, and Dr. Sykes shares why understanding them matters. This conversation is educational and not medical advice.
Key Takeaways
- Dr. Lucinda Sykes joins Mike Korlin to talk about the science of sleep, its influence on the brain, and the chemical processes that govern it.
- We cover the stages of sleep, from REM to deep sleep, and why each stage plays a role in how we feel.
- Dr. Sykes shares a European study of 8,000 people that, as described in the episode, linked poor sleep over time to a 30% higher likelihood of dementia symptoms. She notes the connection needs further study.
- We talk about how sleep medications and natural sleep aids, including cannabis-derived options like CBN, can affect the brain’s chemistry, and why caution makes sense.
- Healthy sleep habits are the foundation, whatever else you try.
- If sleep problems persist, talk with a doctor.

Meet the Guest: Dr. Lucinda Sykes
Dr. Lucinda Sykes is a seasoned expert on sleep. In this episode she unravels the mechanisms at work while we rest and offers insights on how to think about and prioritize sleep. You can find more of her work at lucindasykesmd.com.
The Complex World of Sleep
There is more to sleep than meets the eye. In the episode we explore the stages of sleep, from the rapid eye movement (REM) phase to deep sleep, and the role each stage plays in restoring the body and mind. We also talk about the chemicals involved in regulating sleep and why a balanced brain chemistry matters.
Sleeplessness Is More Than a Restless Night
Most of us have had nights of tossing and turning. According to Dr. Sykes, sleeplessness is more than an inconvenience, especially as we age. For a long time the medical community considered sleep trouble in older adults a normal part of aging. More recent thinking, she suggests, challenges that.
The post describes chronic sleep deprivation as getting less than six hours of sleep a night on a consistent basis, and notes that over time it has been linked with changes in brain chemistry and a higher risk of dementia and other brain-related conditions. We also touch on how sleeplessness affects women over 50.
The Link Between Sleep and Dementia
One of the standout points is the study Dr. Sykes shared. In the episode, it is described as a study of 8,000 people in Europe where those with poor sleeping habits over time had a 30% greater likelihood of dementia symptoms. The 30% figure stood out to me. As we note in the post, the connection requires further study, and this should be treated as one data point, not a prediction about any individual.
Medication and Sleep
Dr. Sykes explains the interplay between sleep, the brain’s natural chemicals, and the way sleep medications may disrupt them. The takeaway is that seeking a quick chemical fix can come with unintended consequences. This is not advice to start or stop any medication. If you have questions about medications you take, speak to your prescribing provider.
Natural Sleep Aids and Cannabinoids
We also discuss natural sleep aids, including cannabis and CBN (cannabinol), a cannabis-derived compound that has grown in popularity recently. The point we make is to build a healthy relationship with these substances, since they too can affect brain chemistry. They may seem to help in the short term, but needing more over time to get the same effect can be a sign of overuse.
If you are exploring options on the shelf, browse our Sleep Aid category or read our guide to CBD gummies with melatonin for sleep. These are for adults, laws and product rules vary by location (see our Product Warnings & Disclosures), and it is wise to talk with a healthcare professional first, especially if you take medications.
Cultivating Healthy Sleep Habits
The bottom line is clear: most of us need more sleep. Dr. Sykes encourages better sleep habits as a foundation. General habits that come up in discussions like this one include:
- Keeping a consistent sleep and wake schedule, even on weekends
- Keeping your bedroom dark, quiet, and cool
- Limiting screens close to bedtime
- Avoiding caffeine and heavy meals late in the day
- Relaxation practices such as deep breathing or meditation

Other Sleep Disorders
The post includes statistics compiled from sources such as the National Heart, Lung, and Blood Institute and the Sleep Foundation. According to estimates, 50 million to 70 million people have ongoing sleep disorders, the most common being insomnia, sleep apnea, and narcolepsy. If you suspect one of these, a doctor or sleep specialist can help you sort it out.
FAQ
Sleep is a sequence of stages. It includes rapid eye movement (REM) and non-REM sleep. Non-REM sleep has three stages, with stage 3 being the deepest. The different stages serve different functions, and understanding them helps explain why both quantity and quality of sleep matter.
According to the discussion, consistently sleeping fewer than six hours a night is linked with changes in brain chemistry over time, including possible effects on mood and thinking. This is general information and does not diagnose anyone.
Dr. Sykes shared a European study of 8,000 people in which poor sleep over time was linked to a 30% higher likelihood of dementia symptoms. The connection needs further study.
That is a decision for you and your healthcare provider. The episode discusses how they can disrupt the brain’s natural balance, so speak with a professional before using or stopping any sleep medication.
Safety depends on the person, the product, and the dose. The episode encourages a careful, informed approach and a good relationship with any substance. Check with a healthcare professional, especially if you take medications or have a health condition.
Start with a regular schedule, a comfortable sleep environment, less screen time before bed, and relaxation practices. If problems continue, see a doctor.
