Neuroscientist Rachel Barr has raised concerns about the benefits of waking up at 5am, citing potential harm to one’s brain. She explains that while setting an alarm can be done at any time, our bodies may not be ready to wake up at such an early hour.
The key issue lies in our internal clock, or circadian rhythm, which regulates hunger, sleepiness, and alertness. Genetics also play a role in determining when we feel most awake. According to Barr, if you’re a natural “night owl,” waking up at 5am may not be suitable, as it can disrupt REM sleep patterns.
REM sleep is crucial for brain health, and research suggests that delayed REM sleep can increase the risk of cognitive decline and Alzheimer’s disease. A study found that individuals who slept for over 98 minutes after falling asleep had elevated levels of toxic proteins, including amyloid and tau, which are associated with an increased risk of Alzheimer’s.
Sleep consultant Rosey Davidson emphasizes that getting enough sleep is essential for brain health, enhancing memories, improving mood regulation, and supporting mental well-being. She suggests that the best time to rise varies from person to person, and forcing oneself into a routine can have severe consequences on brain function.
Barr advises against stressing over ideal sleep schedules, as lifestyle factors can affect it. Instead, prioritizing one’s sleep window and creating an environment that supports rest is crucial. By being mindful of wind-down times and relaxing before bed, individuals can optimize their sleep and wake up feeling refreshed and alert.
