Dr. Sanchari Sinha Dutta, Ph.D. via News-Medical – Why do so many people hit snooze? This global smartphone study uncovers surprising patterns and raises questions about how repeated alarms may be impacting our sleep health. Harvard Medical School researchers conducted a study on users of a sleep monitoring smartphone application to explore the prevalence and characteristics of snooze alarm use, a typical but poorly understood human behavior. The findings are published in the journal Scientific Reports. Background Sleep is a complex and dynamic physiological process for maintaining health and well-being. Internal circadian rhythms, together with time spent awake, influence the timing and duration of sleep. However, humans often subdue these biological regulatory processes for personal or professional reasons. The recommended duration of night sleep for adults ranges from 7 to 9 hours. However, over the past several decades, a trend of not meeting this recommendation has been observed in global populations, which may increase the risk of both physical and mental health complications. Although humans naturally wake after sufficient sleep, they often require assistance, such as the use of an alarm clock, to meet a desired wake time under conditions of insufficient sleep duration. The “snooze” function commonly available in alarm clocks is designed to repeatedly alert the sleeper in fixed intervals following the initial alarm. However, according to sleep experts, a sleeper should set an alarm for the last realistic wake time instead of setting a snooze alarm to get as much consolidated, uninterrupted, high-quality sleep as possible. Using a snooze alarm is a typical but poorly understood human behavior. Only a few studies have investigated the health impact of snooze alarms and reported that this practice is associated with short and poor-quality sleep and feelings of drowsiness upon waking. In the current study, researchers analyzed a large dataset to explore the prevalence and characteristics of snooze alarm use across countries, cultures, and climates. Study design The study analyzed a large pool of data from the users of a sleep monitoring smartphone application called “SleepCycle.” The database included six months of data from 21,222 app users and more than 3 million sleep sessions from users across four continents. The dataset included users who elected to use the traditional snooze feature, logged sleep sessions 50% or more of the nights in each month of the monitoring interval, used the app on an iPhone as opposed to an Android device, and consented for their data to be used in research. Study findings The analysis of sleep sessions opted by users at night revealed that more than half (specifically, 55.6%) of sessions end up with a snooze alarm. Of all users, about 45% were heavy snooze alarm users, 28% were moderate users, and 27% were light users. Compared to light and moderate users who used snooze alarm less frequently and demonstrated more consistent sleep times, heavy snooze alarm users, who used the alarm almost every day and multiple times within each day, demonstrated erratic sleep/wake times. Overall, users pressed the snooze alarm approximately 2.4 times daily and spent on average 10.8 minutes snoozing. This is equivalent to a monthly loss of nearly one 6-hour night of sleep. Heavy users chose the snooze alarm approximately 4 times daily, resulting in about 20 minutes of snoozing duration. On the other hand, light users chose the snooze alarm on average 1.2 times a day, resulting in 3 minutes of snoozing duration. The use of a snooze alarm was more frequent during weekdays (Monday to Friday) and less frequent on weekends (Saturday and Sunday). Fewer commitments on weekends among employees and students might be the reason for this less frequent use. The duration of snooze alarm use was significantly longer among women than men. The researchers suggest that this could stem from factors such as additional childcare and household duties over professional duties or an increased risk for insomnia among women, which might be the reason for women’s higher reliance on the snooze alarm. Month-to-month variations in snooze alarm use were minimal in the study population. Users in the Northern hemisphere exhibited slightly higher usage in December and less usage in September, while users in the Southern hemisphere exhibited the opposite trend. These variations might be associated with changes in seasonal sleep patterns due to factors like less access to natural light during winter months, potentially causing a delay in circadian rhythms. The frequency of snooze alarm use was also higher among long sleepers (more than 9 hours of sleep) compared to that among short sleepers (less than 7 hours of sleep) or those meeting the recommended sleep duration (7 to 9 hours of sleep). As researchers mentioned, higher snooze alarm usage observed after long sleep sessions could be indicative of hypersomnia or compensatory sleep to recover from sleep deficiency. The snooze alarm usage frequency was also higher among sleepers who went to bed later than usual compared to those who went to bed earlier. An unusual sleeping time is more common among shift workers who may have inadequate time in bed, and hence, more reliance on the snooze alarm. Furthermore, users with misaligned sleep may experience more fragmented sleep, and thus, greater reliance upon the snooze alarm. While the study provides valuable insights from a large, international dataset using objective snooze alarm data, the researchers acknowledge certain limitations. These include the sleep data being app-derived, which may overestimate actual sleep duration as it doesn’t account for time taken to fall asleep or awakenings during the night. Additionally, it was not certain if users were actually sleeping between alarms, and the sample of app users may not be fully representative of the general global population. The study also did not have information on the age of participants or self-reported feelings of grogginess upon waking. Overall study findings Overall, the study findings highlight that a higher frequency of snooze alarm use might be indicative of a poor sleep pattern and potentially part of the phenotype of poor sleep health. Given that snooze alarm use is discouraged by experts to avoid sleep fragmentation, researchers highlight the need for future investigations to understand the impact of snooze alarm use on daytime performance and overall health. They also suggest that public health messages encouraging individuals to set their alarm for the latest possible wake time, rather than relying on the snooze button, could be a viable strategy to promote better sleep habits.

How Bedtime Screen Use Affects Sleep in Early Adolescents

The AHA! Team — Thu, 05 Sep 2024 08:02:43 +0000

Dr. Sushama R. Chaphalkar, PhD. via News-Medical – In a recent study published in the Journal of Adolescent Health, researchers investigate the potential link between bedtime screen use in early adolescents and sleep outcomes after one year. Overall, bedtime screen use was associated with shorter sleep durations and increased sleep disturbances one year later in early adolescence. How does screentime affect sleep? Research shows that screen use, which includes television, computers, and mobile phones, increases during early adolescence between the ages of 10 and 15 years and has been associated with academic, mental health, and sleep issues. Adequate sleep is vital for adolescents’ behavioral, emotional, and cognitive development. In fact, early sleep problems can be used to predict behavioral and emotional concerns, as well as weight gain later in life. Most studies on screen use and sleep are cross-sectional in design and focus on daily rather than bedtime use. Studies from Switzerland, the United Kingdom, and Norway reported that bedtime screen use negatively impacts sleep; however, these studies were associated with several limitations. Likewise, the United States Adolescent Brain and Cognitive Development (ABCD) Study recently reported that bedtime screen use was associated with sleep disturbances; however, the cross-sectional nature of this study prevented the researchers from establishing causality. About the study The present study included 9,398 participants between 11 and 12 years of age with complete data from the ABCD study. About 48% of the study participants were female, 45% were non-White, and the average age was 12. Screen usage around bedtime was assessed using a nine-item survey that included various screen activities, device presence, and phone usage at bedtime. The activities included gaming, social media use, texting, video calling, internet browsing, and watching movies, videos, or television. Overall screen usage data were collected through the Youth Screen Time Survey, which calculated average daily screen time. In years two and three of the ABCD study, caregivers assessed sleep disturbance using a 26-item measure, which calculated an overall sleep-wake disturbance score and subscale score for disorders of initiating and maintaining sleep. Sleep duration was assessed using the Munich Chronotype questionnaire, which calculated the weighted average sleep duration. Confounding data on sex, race/ethnicity, age, household income, parent education, study site, melatonin use, adverse childhood experiences, and depression symptoms were also collected. Statistical analysis involved using logistic, ordinal logistic, multiple linear regression models, and propensity weights. Study findings About 63% of participants had a television or electronic device in their bedroom, whereas 54.9% turned off their phones before going to sleep. In one week, 16.2% were woken by phone calls or messages, whereas 19.3% used a device if they woke up at night. Bedtime screen behaviors increased from years two to three. Having a television or electronic device in the bedroom was associated with shorter weekly sleep duration. While leaving the phone’s ringer on was associated with increased sleep disturbances and shorter sleep durations, putting the ringer on silent or vibrate was associated with shorter sleep durations. Using electronic devices before bed was associated with shorter weekly sleep durations and greater sleep disturbances. Specific activities like talking on the phone, texting, playing music, and using social media were associated with increased sleep disturbances and more severe insomnia. Total daily recreational screentime was also related to sleep disturbances and shorter sleep durations, although to a lesser extent. Being woken by phone calls or texts and using devices during the night were both associated with reduced sleep durations and increased sleep disturbances. Although bedtime screen use did not affect changes in sleep duration over time, total screen time and playing music before bed were associated with higher sleep disturbance scores. Important strengths of the current study include the large and diverse study cohort, strong external validity, and a prospective design focusing on early adolescents. However, the study findings are subject to potential recall, social desirability, and selection biases. Furthermore, the current study did not include details on screen use context, changes in screen use patterns, and sleep disturbance classifications. Conclusions The study findings emphasize the urgent need for clinicians to address bedtime screen use among adolescents. Moreover, the researchers suggest that parents should implement strategies like a ‘Family Media Use Plan’ to limit screen time before bed. These observations provide important insights into the potential benefits of reducing bedtime screen use for improving sleep. Future studies should explore the mechanisms that contribute to this association, use objective measures, and assess how bedtime screen use impacts sleep as adolescents age.

Are You Addicted to Doomscrolling? (Plus How to Stop)

AHA Publisher — Wed, 18 Nov 2020 08:00:55 +0000

Christine Ruggeri, CHHC via Dr. Axe – Do you have a habit of scrolling endlessly through social media, looking for answers or clarity? If this perpetual rabbit hole of scrolling — refreshing and scrolling again — is leaving you feeling agitated, hopeless and drained, you’re officially doomscrolling. Doomscrolling can have a major impact on your mental and physical health. If you’re caught in the routine of scrolling several times throughout the day, searching aimlessly for more and more negative content, it’s time to cut back on your time online and find new, more positive outlets. It’s for your own health, after all. What Is Doomscrolling? Doomscrolling is when you continue to scroll through bad news or even seek it out, even when it leaves you feeling sad or agitated. It’s been described as an “endless procession of negative online news.” For many people, the pandemic has intensified these habits. Findings from this past April that were reported by Pew Research Center indicate that 53 percent of American adults say the internet has been essential for them during the pandemic. In addition, 34 percent of U.S. adults describe the internet as “important, but not essential.” It appears that we may be using the internet now more than ever. Over the last eight months, many adults began working from home, from their computers, making internet use even more prevalent. People also are suffering from feelings of isolation and loneliness, so they use the internet to connect with others. But why are people doomscrolling if it leaves them feeling sad or even panicked? For some, it’s like an addiction that’s fed by the false notion that staying informed will provide a sense of security — when, in reality, it causes just the opposite. Doomscrolling not only negatively impacts your mood, but it can also disrupt sleep, focus and concentration. Because it alters your mental health, it can also negatively affect your physical health and cause issues such as: headaches sugar cravings overeating low energy brain fog digestive issues If you’re constantly doomscrolling, you may be dealing with chronic stress, which can have a serious impact on your overall health. How to Stop 1. Set Aside Time to Scroll If you like to scroll through your Facebook feed or Twitter for the latest news, you’re not alone. Many adults use social media as their news source. To avoid doomscrolling and its effects on your mental and physical health, however, set aside a specific amount of time for scrolling through the news. Maybe that’s 20 minutes in the morning and 20 minutes in the evening. Make it work for your schedule, and set a timer on your phone if you have to. You can also track your screen time to keep yourself accountable. Why is it so important to reduce your social media and scrolling time? One study published in the American Journal of Health Behavior indicates that people categorized as “Wired” or “Connected” in defining their social media use have an increased association with the the risk for depression and anxiety. 2. Declutter Your Phone and Laptop If you’re prone to doomscrolling, it may be time to minimize the apps on your phone, laptop and desktop so you’re less likely to use them in between tasks or when “wasting time.” If you’re triggered by one app in particular, then delete it from your phone so that it’s not always at your fingertips. Why consider deleting a social media app? A study published in Cureusfound that prolonged use of social media platforms, such as Facebook, may be related to negative signs and symptoms of depression, anxiety and stress. 3. Stop All Notifications From News Sources Are you getting a push notification every time a news story breaks? If so, stop! Push notifications are meant to enhance and increase smartphone engagement. They can be distracting and leave you scrolling, again, even when you were in middle of a task. Stop all push notifications, which entice you to spend more time scrolling. 4. Don’t Click on Triggering Articles You can usually tell from the headline whether or not the article will trigger you. More bad news? More divisive? Then skip it. These articles can leave you feeling isolated, sad, angry and hopeless. Instead, stick to positive, informative and uplifting content. 5. Avoid Debate Commenting Let’s face it — your social media debate commenting rarely changes a person’s mind or gives you a sense of security or community. In fact, it likely makes you feel more isolated and agitated. One study conducted in the U.K. suggests that posting about feelings and venting on social media predicted low mood and self-estreem and high paranoia. If you’re doomscrolling and come across a post that makes you want to comment, perhaps discuss the issue with your spouse or loved one instead. You’re likely to get better clarity and positive reinforcement that way. 6. Don’t Read News Articles on Social Media Does all of your news come from social media? If you are constantly refreshing your social media timelines for the newest stories, it’s a much better idea to visit a specific news website instead. Or, better yet, rely on a printed newspaper that you can read leisurely in the morning and put away for the remainder of the day. You may actually retain the information when reading news in a different format, like print. One study published in Human Factors found that a scrolling format reduced understanding of complex topics from web pages, especially for readers who were lower in working memory capacity. 7. Find Your People We need to maintain a sense of community for our mental and physical health. Communicating with groups of like-minded people is good for the soul. Organizing charity events or working together to conduct acts of kindness make it even better. Research shows that community-belonging is an important component of health prevention and can even promote healthier behaviors, like exercise and improved diet. 8. Find Other Outlets If you’re doomscrolling out of boredom, work on finding other outlets that actually improve your overall health and well-being. Add uplifting activities into your daily routine, like going for a walk outdoors, yoga at home, meditation, reading a fictional story, talking on the phone or Zooming with friends, and cooking for loved ones.
