Heart disease ranks among the top causes of death globally. Many recognize that poor diet, lack of physical activity, and smoking contribute to this risk.
Recent research indicates that sleep issues might be equally significant, particularly when multiple problems occur simultaneously.
Researchers from Yale School of Medicine discovered that individuals dealing with both insomnia and sleep apnea face a substantially higher likelihood of developing heart disease and hypertension. Their results were published in the Journal of the American Heart Association.
The study analyzed data from nearly one million veterans in the United States. This extensive sample provided insights into how sleep habits influence health over time.
Insomnia and sleep apnea are both prevalent. Insomnia makes it difficult to fall asleep or stay asleep, whereas sleep apnea involves repeated breathing pauses during sleep. While each condition alone can affect health, having both turns out to be particularly risky.
This combined condition is known as COMISA. Individuals with COMISA were found to be at a significantly greater risk of cardiovascular issues compared to those with only one sleep disorder.
The underlying reason may relate to sleep’s role in bodily recovery. During restful sleep, the heart and blood vessels take a break and repair. This process is vital for maintaining healthy blood pressure and circulation.
When sleep quality is compromised, the body cannot complete this restorative process. Breathing interruptions from sleep apnea and frequent awakenings from insomnia disturb the body’s natural rhythm. Over time, this can put added stress on the heart and elevate disease risk.
The researchers stress that sleep should be viewed as a fundamental aspect of overall health, rather than a minor concern. Many individuals overlook sleep problems or address them separately, but this study underscores the need for a more integrated approach.
They recommend that healthcare providers assess for both insomnia and sleep apnea together instead of focusing on just one. Prompt treatment of both conditions could help prevent the development of serious heart issues.
Prevention also plays a crucial role. Instead of waiting for heart disease symptoms to appear, health systems should prioritize early signs, like poor sleep, to intervene sooner.

Recent years have seen a rise in the use of sleep-tracking apps, with many individuals turning to these tools to better understand their sleep patterns. These apps, often connected to smartwatches or smartphones, claim to measure sleep duration, how quickly one falls asleep, and the overall quality or restfulness of sleep.
As health and wellness become more prominent, sleep monitoring has gained popularity. People hope that tracking their sleep can lead to feeling more energized and improving overall well-being. However, a recent study conducted by researchers in Norway questions the effectiveness of these apps, indicating they may not always be beneficial—and in some cases, could even worsen sleep, especially for those already dealing with insomnia.
The study was published in Frontiers in Psychology and explores critical issues about how we incorporate technology into our health routines. Led by scientists from the University of Bergen, including Håkon Lundekvam Berge and Karl Erik Lundekvam, the research aimed to understand how users perceive their sleep when using these apps and whether they help or hinder sleep quality.
Surveys involving 1,002 adults from Norway revealed widespread usage: nearly 46% of participants had used or were currently using sleep-tracking apps. Women and individuals under 50 were more likely to use these tools than men and older adults. Many users found some benefits; approximately 15% believed the apps helped improve their sleep, and nearly half appreciated gaining insights into their sleep patterns. Such awareness might encourage healthier habits, like going to bed earlier or reducing screen time before sleep.
Nonetheless, the study identified notable drawbacks. About 17% of users reported increased worry about their sleep because of the data they received. A small portion—around 2.3%—even said their sleep quality worsened overall. The effects appeared more pronounced among younger adults, who were more engaged with technology and more attentive to sleep data.
Particularly concerning is the impact on individuals with existing sleep issues. Those with insomnia symptoms found that detailed sleep data could amplify anxiety and stress, making it harder to fall asleep. This aligns with the concept of “orthosomnia,” a condition where individuals become overly fixated on achieving perfect sleep scores, which ironically worsens their sleep quality by causing increased worry and tension.
The accuracy of sleep apps remains uncertain. Many estimate sleep stages based on movement or heart rate, but these methods don’t always match the precision of clinical sleep studies. As a result, the information provided to users may not perfectly reflect actual sleep quality.
The study also notes limitations, such as reliance on self-reported data, which can be biased or inaccurate, and the fact that participants volunteered, potentially skewing the results toward those already interested in sleep issues.
Despite these considerations, the findings suggest that sleep apps can offer benefits for some but are not universally suitable—particularly for those prone to anxiety about their sleep. The researchers recommend not becoming overly dependent on these digital tools. Instead, paying attention to how you feel during the day and adopting simple sleep habits—like maintaining a consistent bedtime, going to bed when sleepy, and reducing screen time before sleep—may be more effective.
Ultimately, while sleep apps can be useful, they are not a cure-all. For individuals with sleep challenges, especially insomnia, these tools may cause more harm than good. Maintaining healthy routines and focusing on overall lifestyle habits tend to yield better results than obsessing over sleep scores.

Mental health experts often describe “hyperarousal” as a state where the mind and body stay unusually alert, tense, or activated. Those experiencing hyperarousal may feel constantly on edge, struggle to relax, or have difficulty sleeping.
This condition has long been associated with various mental health issues, such as insomnia, depression, anxiety, post-traumatic stress disorder (PTSD), and ADHD.
However, researchers have noticed something confusing. Even though many mention hyperarousal, they don’t always mean exactly the same thing when they use the term.
Different studies show that hyperarousal can involve slightly different experiences or symptoms. This ambiguity makes it challenging for scientists and doctors to fully understand the condition or develop effective treatments.
To address this, researchers at the Netherlands Institute for Neuroscience decided to investigate what hyperarousal really entails. Their goal was to determine if hyperarousal is a single condition experienced across multiple disorders or if it includes several distinct forms.
Led by researcher Tom Bresser, the team’s study was published in the journal eClinicalMedicine. Bresser explained that scientists already understand quite a bit about how hyperarousal contributes to insomnia.
People with insomnia often experience racing thoughts, heightened alertness, or physical tension preventing sleep. But since hyperarousal also appears in many other mental health conditions, an important question arose.
Specifically, the researchers asked whether all these cases reflect the same underlying process or if different types of hyperarousal might exist.
To explore this, the team developed a comprehensive questionnaire that incorporated questions traditionally used to measure symptoms across different mental health conditions, not just one.
This method allowed them to capture various aspects of stress, alertness, emotional tension, and mental activation.
Nearly 500 volunteers took part in the study. Participants were recruited through sleepregister.nl, a Dutch platform where individuals volunteer for sleep-related research.
Each person answered the complete questionnaire, giving the researchers a rich dataset about their sleep habits, emotional states, and mental health experiences.
When analyzing the responses, the scientists found something unexpected: hyperarousal isn’t a single, uniform condition. Instead, the data pointed to seven separate types of hyperarousal. These different forms appeared across various mental health issues, though their intensity varied depending on the condition.
For example, those with insomnia might experience specific hyperarousal types more intensely, like mental alertness or racing thoughts at night. Conversely, individuals with anxiety might show other types, such as persistent worry or heightened emotional sensitivity.
Similarly, people with depression, PTSD, panic disorder, or ADHD might display different combinations of these hyperarousal types.
This suggests that hyperarousal isn’t a one-size-fits-all phenomenon. Instead, it may consist of various related processes affecting the brain and body differently.
The researchers created a shorter, specialized questionnaire to measure these seven hyperarousal types more easily. This new tool simplifies studying hyperarousal without needing multiple psychological assessments.
According to Bresser, this new questionnaire could help scientists better map hyperarousal in a clear and detailed way. The Netherlands Institute for Neuroscience’s sleep lab has already begun using it in new studies of insomnia and anxiety.
The team is also examining how these hyperarousal types are connected to brain activity, exploring which regions are involved in each form. Understanding these mechanisms could shed light on how these states develop and why they appear in different mental health conditions.
Gaining a deeper understanding of hyperarousal might also improve psychological treatments. Often, patients seek help for one primary issue, like anxiety or sleep problems. But during therapy, clinicians may discover overlapping symptoms related to other conditions, complicating treatment.
If clinicians identify the specific types of hyperarousal underlying a patient’s symptoms, they could tailor interventions more precisely. Instead of focusing solely on one disorder, they could target the fundamental hyperarousal patterns influencing multiple symptoms.
Scientifically, this study represents a significant step in clarifying a long-used but sometimes vaguely defined concept. By distinguishing seven different types, it offers a more detailed framework for understanding how stress, alertness, and emotional activation impact mental health.
Additionally, the findings highlight that many mental health disorders share common underlying processes. Conditions that appear very different may, in fact, be connected by similar biological or psychological mechanisms.
Further research will be needed to confirm these results and explore how these hyperarousal types relate to brain function and behavior. Nonetheless, this study paves the way for new insights into mental health research and treatment options.
This refined understanding of hyperarousal could eventually lead to better diagnostics and more personalized therapies for those dealing with insomnia, anxiety, depression, and other mental health conditions.
We have gradually become used to using screens while lying in bed, despite our awareness of the potential physical and mental drawbacks. A recent study indicated that individuals who engage with electronic devices before sleep face a 33% higher rate of poor sleep quality.
Further research reveals that using screens in bed can elevate the chances of developing insomnia by an alarming 59% among young adults and teenagers. Additionally, this habit reduces sleep duration by 24 minutes. To add to the concern, each extra hour spent on screens correlates with a further increase in insomnia risk.
According to a study published in the journal Frontiers Psychiatry, “The results showed that increased screen time in bed correlates with a higher likelihood of reporting symptoms of insomnia and shorter sleep duration, whereby each additional hour of screen time was linked to a 63% increase in insomnia risk and 24 minutes less sleep.”
The research concentrated on over 45,000 students in Norway, examining the impact of their screen usage in bed on sleeping patterns. Participants provided information not just about their sleep and wake times but also how long it took them to fall asleep, any sleep-related challenges, daytime drowsiness, and the persistence of their sleep issues.

These aspects were integral in forming an insomnia profile. Insomnia is defined medically as “difficulty falling asleep or staying asleep, or frequently waking up.” The American Academy of Sleep Medicine states that approximately 12% of people in the U.S. suffer from chronic insomnia, while nearly a third of the population experiences temporary symptoms.
Social Media Is Not the Sole Culprit
Social media often receives criticism for its role in keeping us glued to screens, bombarding us with a relentless flow of algorithmically curated content. This leads to a cycle of endless scrolling that can consume hours without us realizing it. Moreover, the nature of social media content itself can have an especially troubling effect on children.

Experts assert that there’s no direct link between social media use and its influence on sleep quality. Data analyzed by specialists shows that social media has effects comparable to any other screen-related activities, such as gaming, streaming, or web surfing.
“Regardless of screen time, users who engaged solely with social media reported the lowest rates of insomnia symptoms and the longest sleep duration, while those participating in different screen activities experienced the poorest sleep,” the research states.
That said, it’s essential to note that social media apps generate the majority of notifications on smartphones. While they may not directly contribute to hours of content consumption, the alerts can disrupt sleep or distract the mind.
