☆ Why Do I Wake Up Right Before My Alarm?
  + stars: | 2023-06-27 | by ( Melinda Wenner Moyer | ) www.nytimes.com   time to read: +1 min
Q: Sometimes I wake up a minute or two before my alarm is set to go off. In one telephone survey published in 1997, for instance, researchers from Iowa and Minnesota randomly interviewed 269 adults mainly in the Midwest. About three-quarters of those interviewed said they sometimes woke up before their alarms, and just under a quarter said they woke up so reliably that they never had to use an alarm. After the research team published a newspaper ad asking for people who always or regularly woke up at specific times without using an alarm, they invited 15 of those respondents into a lab and tracked their sleep for three nights. They found that five of the 15 awoke within 10 minutes of their target wake-up times all three times.

When we've been awake for a long time, our sleep drive kicks in and tells us we need to sleep. During REM sleep, the cortex – responsible for cognition and emotion-processing – is activated in some regions and deactivated in others. After cycling through non-REM and REM sleep around 4 to 5 times, the basal forebrain and other structures receive signals to start exiting sleep. WHEN SLEEP GOES WRONGIn the U.S. alone, 50 to 70 million people experience some type of chronic sleep disorder, according to the American Academy of Sleep Medicine (AASM). In the United States, a list of board-certified sleep medicine physicians and accredited sleep disorders centers is available from the American Academy of Sleep Medicine.
