Women Use REM-Disruptive Snooze Alarm More Often Than Men
An analysis of more than 21,000 people worldwide suggested that 56% used the snooze function on their alarm regularly, interrupting sleep patterns researchers said are important for rapid eye movement (REM) sleep. Women had significantly longer snooze durations than men (11.5 vs 10.2 minutes), with heavy users averaging 20.2 minutes of daily snoozing, investigators found.
METHODOLOGY:
Researchers included data of over 3 million sleep sessions of over 21,000 users of a sleep-monitoring smartphone application (54% men) from July 2022 to December 2022.
Participants resided primarily in the United States, followed by the United Kingdom, Japan, Australia, and Germany.
Users could opt for traditional snooze features in the smartphone application. Sleep sessions lasting 4 hours or longer were included in the analysis.
Participants were heavy, moderate, or light users if > 80%, 40%-60%, and < 20% of their sleep sessions ended with a snooze alarm, respectively.
TAKEAWAY:
In all, 56% of sleep sessions ended with the use of a snooze alarm. Women more frequently used the snooze alarm (mean snooze alarm sessions, 2.5; 95% CI, 2.5-2.6; mean daily snoozing time, 11.5 minutes) than men (mean snooze alarm sessions, 2.3; 95% CI, 2.3-2.4; mean daily snoozing time, 10.2 minutes).
The use of snooze alarms was significantly higher on weekdays than on weekends ( P < .001). Heavy, moderate, and light users pressed the snooze button 4, 1.7, and 1.2 times and snoozed for an average of 20.2, 6.3, and 3.0 minutes, respectively.
< .001). Heavy, moderate, and light users pressed the snooze button 4, 1.7, and 1.2 times and snoozed for an average of 20.2, 6.3, and 3.0 minutes, respectively. Participants in Sweden used snooze alarms the most (mean snooze alarm sessions, 2.7), and those in Japan and Australia used it the least (mean snooze alarm sessions, 2.2).
Long sleep sessions (> 9 hours) were more likely to end with a snooze alarm than those of the recommended duration (7-9 hours) or short sleep sessions (< 7 hours). Participants who went to bed earlier than usual used a snooze alarm less often, whereas those who went to bed later than usual used it more often.
IN PRACTICE:
'The hours just before waking are rich in rapid eye movement sleep. Hitting the snooze alarm will interrupt these critical stages of sleep and typically only offer you light sleep in between snooze alarms. The best approach for optimizing your sleep and next day performance is to set your alarm for the latest possible time, then commit to getting out of bed when your first alarm goes off,' lead investigator Rebecca Robbins, PhD, Division of Sleep Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, said in a press release.
SOURCE:
This study was published online on May 19 in Scientific Reports .
LIMITATIONS:
This study's sleep duration likely overestimated actual sleep due to unmeasured sleep latency and awakenings. Data reflected time in bed, not true sleep time. Snooze alarm data were objective, but users may have been awake during snooze periods, potentially inflating snooze estimates. Data on age and self-reported feelings on waking up were not available. Additionally, wake time variability and self-reported sleep quality were not assessed.
DISCLOSURES:
Funding information was not provided for this study. Several authors reported having financial relationships with various sources. One author was employed by the application manufacturer. Details are provided in the original article.

Who Should Consider Getting Flood Insurance? These Days, Almost Everyone.
With the Atlantic hurricane season about to start, this may be good time to consider buying flood insurance for your home — even if you don't live in a hurricane-prone area. Officials at the National Oceanic and Atmospheric Administration said this month that they were expecting more than the average number of hurricanes during the season, which begins June 1 and runs through November. NOAA predicts as many as 19 named storms, with six to 10 of them strengthening into hurricanes. An average season has 14 named storms with seven becoming hurricanes. Flood insurance should not be seen as important only for property owners near the ocean, insurance experts note. While properties near the coast are in particular peril, areas far inland have had severe flooding in recent years as a warming climate spawns intense storms that drop heavy rainfall. Won't my homeowner insurance policy cover flood damage? No. Standard homeowner insurance policies don't cover damage from floods, which are the most common and costly natural disaster in the United States. Flood protection — which typically covers damage from rising water entering a home — requires a separate policy, available from the federal government's National Flood Insurance Program or from certain private insurers. Borrowers with federally backed mortgages in certain high-risk areas are generally required to carry flood coverage, but it's largely optional otherwise. What if I don't live near a coastline? You should still evaluate buying flood coverage, insurance experts say. Consider this example. In September, Hurricane Helene made landfall on Florida's gulf coast as a powerful Category 4 storm, then moved inland, traveling hundreds of miles north. The storm drenched parts of six states and caused record flooding in western North Carolina. Want all of The Times? Subscribe.

Cicada invasion begins as Brood XIV swarms parts of U.S. See photos.
This year's cicada invasion has started as Brood XIV emerges from underground and swarms parts of the U.S. The insects are expected to be concentrated in Kentucky and Tennessee, and show up in parts of Georgia, Illinois, Indiana, North Carolina, Virginia, West Virginia, as well as in Cape Cod, Massachusetts, central Pennsylvania and Long Island, New York. It is a one-in-17-year event for Brood XIV, which digs its way up from the soil as it warms and descends on neighborhoods in the billions. The brood, however, is the only group emerging this spring, meaning there likely won't be as many cicadas as last year when multiple broods surfaced simultaneously. Cicada nymphs develop in the soil over a long period and surface when the ground hits 64 degrees Fahrenheit. They can be heard crunching through the grass to climb up trees, plants, people or any vertical surface, with a forceful quality about it. Experts say they're not dangerous to pets or humans, and they don't sting or bite — and aren't poisonous or venomous. Instead, cicadas are also largely beneficial to the ecosystem, serving as a source of food source for birds and other predators. They can aerate soil and provide nutrients for trees when they decompose. Photos show this year's invasion beginning.
