Dr. Cservenka: There had been limited research on whether frequent cannabis use is associated with changes in individuals' diurnal stress activity, which can be measured by examining the cortisol awakening response. However, some previous studies had shown that the typical rise of cortisol in the morning, which is thought to be a marker of our body's preparation for managing the stressors of the day, may be blunted among individuals with alcohol use disorder. A recent study by Glodosky et al., 2026, also suggested this may be the case among those with chronic cannabis use, so we attempted to replicate those findings. Although we did not find group differences in the cortisol awakening response (the difference in cortisol 30 minutes post-awakening and at the time of awakening) between individuals who engaged in frequent cannabis use relative to controls, we did find that cannabis use may be related to higher levels of cortisol at the time of awakening and this was significantly related to cannabis use consequences.
![We've all been there: staring at the ceiling at 3:00 AM, fluffing the pillows for the tenth time, and watching the clock tick closer to morning. In our fast-paced world, getting a full night of deep, restorative sleep can feel like a luxury. While most people reach for blackout curtains, sound machines, or herbal teas, they often overlook a major culprit behind poor sleep: physical misalignment and nervous system stress. If you are tired of waking up groggy, it might be time to look beyond your mattress. Exploring holistic wellness options and finding the best chiropractor near me can be the unexpected key to finally getting the rest your body craves. [IMAGE GOES HERE] The Hidden Connection Between Your Spine and Your Sleep It might seem strange to visit a chiropractor for a sleep issue, but your spine and your sleep quality are deeply connected through your central nervous system. Your spine houses the spinal cord, which acts as the highway for communication between your brain and the rest of your body. When your spine is misaligned, a condition known as a subluxation, it can irritate nearby nerves and keep your body in a constant state of low-grade stress. This physical tension makes it incredibly difficult for your body to transition into the parasympathetic "rest and digest" state necessary for deep sleep, a connection explored further in how hidden stressors accumulate in the spine. 3 Key Ways Chiropractic Care Improves Rest Chiropractic adjustments don't just crack bones; they help reset your body's structural alignment and reduce neural interference, an approach detailed in NCCIH's overview of chiropractic care. Here is how that translates to better nights: 1. Alleviating Chronic Pain and Discomfort The most obvious barrier to sleep is physical pain. Whether it's a dull lower back ache, neck strain from staring at a screen, or tension headaches, pain keeps your brain alert. Gentle chiropractic adjustments align the joints, reduce pressure on compressed discs, and alleviate muscle spasms, allowing you to find a comfortable sleeping position without constantly shifting. 2. Calming the Central Nervous System When your nervous system is overwhelmed by spinal misalignments, your body produces higher levels of cortisol, also known as the stress hormone. High cortisol levels keep your heart rate up and your mind racing. By restoring proper spinal alignment, chiropractic care helps reduce this systemic stress, signaling to your brain that it is safe to relax and drift off. 3. Improving Circulation and Respiration Proper alignment opens up pathways for better blood flow and nerve function. Improved circulation helps your body repair itself more efficiently during the night. Furthermore, neck alignments can improve airway function, which can be highly beneficial for individuals who suffer from tension-related snoring or shallow breathing during sleep. Taking the Next Step Toward Restorative Nights Healthy sleep is not just about the number of hours you spend in bed; it is about the quality of the rest your body achieves. If you have tried changing your bedtime routine and still wake up feeling like you haven't slept at all, it's worth addressing the structural side of the equation. By partnering with a qualified professional, you can address the root spinal imbalances that are keeping your body on high alert. Take control of your health today, search for the best chiropractor near me, and take your first step toward waking up truly refreshed.

Response: The background is that we knew for a while now that neurons work hard to consolidate into memories each experience that we have during the day. But at the same time, it is known that sleep restore activity of our body and physiology. How was that possible? How can the neurons in our brain "work hard" during the time that we are supposed to be restoring our vitals? We found that in between their hard work, during sleep, our neurons take "breaks of activity" so our brain can build memories with precision.

Response: Sleep apnea is associated with incident cardiovascular disease, and is a common chronic condition affecting over a billion people worldwide. In diagnosing and treating sleep apnea, it is imperative to establish the type of sleep apnea—whether it is obstructive or central sleep apnea. The differential contribution of central vs. obstructive sleep apnea toward incidental cardiovascular disease in those with significant sleep apnea has not been well studied.
Our group has developed an automated algorithm that deduces on a breath-by-breath level whether reductions in airflow are predominantly due to obstructive or central phenomena. Our algorithm uses several features that are known to be key in distinguishing the type of events and derives a probability of obstruction across each “small” (reduced amplitude) breath. The breath-by-breath probability is then used to determine whether a patient’s burden of sleep apnea is predominantly obstructive or central.
In this work, we analyzed sleep study data from The Osteoporotic Fractures in Men (MrOS) cohort (N=2793) consisting of elderly men, across two visits separated on average by 6.5 years, and derived the probability of obstruction on a breath-by-breath level. The median probability of obstruction for each subject was computed and analyzed against outcomes of cardiovascular disease. We also assessed the stability of the metric in those without any prevalent cardiovascular disease. We find that median probability of obstruction was stable across the two visits, and those with any incident cardiovascular disease had a lower median probability of obstruction: patients with incident cardiovascular outcomes had a significant burden of sleep apnea that was predominantly “central” in nature.

Response: I think its always important to acknowledge that this is a big team effort. We have the teams from MIT, Celero Systems, West Virgnia University (WVU) and Brigham and Women’s Hospital (BWH) all working together on this. For this study, Celero prototyped the devices that we tested in pre-clinical (Swine) models and in a first-in-human study with the team at WVU.
Our lab focuses on the development of ingestible devices for drug delivery and sensing and these have informed the development of these efforts as you can see.
