Waking up at this time in the morning maybe harmful for you, warns neuroscientist

The trend of waking up at 5am has taken social media by storm, with many touting its productivity benefits. However, experts are now raising concerns about its potential drawbacks, suggesting it could even harm your brain health.Neuroscientist Rachel Barr recently shared her insights on TikTok (@drrachelbarr), questioning the supposed advantages of an early start.

While setting an alarm for 5am might be easy, she warns that your body might not be ready to rise, which can lead to complications.“Is it true that waking up at 5am every morning will help you to get the best out of your brain?” she posed. “We’re often told that the key to productivity and success is early rising, but it’s not just your alarm that decides when you and your brain properly wake up; it’s also your body.”At the heart of this discussion lies our individual internal clocks, commonly referred to as circadian rhythms, which govern our levels of hunger, sleepiness, and alertness.

While light and darkness play a significant role in regulating these rhythms, a substantial portion is influenced by our genetics.Rachel explained in her video from last year, “If you have the genetic profile of a night owl, it means you sleep and wake a little bit later, and 5am is probably not going to cut it.

Not only does that mean that night owls tend to be more productive later in the day, but it also means that if you're getting up at 5am, you run the risk of losing most of your REM sleep.”REM, or rapid eye movement, is one of the five stages we cycle through during sleep.
