Waking up at 5 am really boosts brain productivity? Neuroscientist reveals the truth

Key points

• For years, the idea of joining the "5 AM Club" has been as a powerful habit of highly successful people.
• From business leaders to self-help gurus, many have claimed that waking up before sunrise can boost productivity, improve focus, and increase the chances of success.
• However, according to neuroscientist and sleep researcher Rachel Barr, the relationship between waking up early and being productive is not as straightforward as many people think.
• She argues that there is no single wake-up time that works best for everyone because our brains and bodies are wired differently.
• In a recent Instagram video, Barr explained that productivity is influenced by a person's natural biological rhythm, known as the circadian rhythm.
