Waking before 5 AM is often framed as a badge of discipline and boasted about by CEOs in self-help podcasts, but it may be more disruptive than productive. <\/p>\n\n\n\n
Human circadian rhythms are biologically programmed for a natural wake time closer to sunrise. <\/p>\n\n\n\n
Regularly rising in the pre-dawn hours can misalign your internal clock, especially if you\u2019re not consistently sleeping early enough to compensate. <\/p>\n\n\n\n
What’s more, circadian misalignment has been linked to increased risk of metabolic dysfunction, mood disorders, and cardiovascular problems. <\/p>\n\n\n\n
Chronically short sleep is another risk: six hours or less per night impairs cognitive performance and insulin sensitivity (PMID: <\/a>24011890<\/a>).<\/p>\n\n\n\n Involuntary early waking at 4:30 AM without an alarm could also be a red flag. It can be triggered by cortisol spikes or even nocturnal blood sugar instability. <\/p>\n\n\n\n Ensure you refrain from eating three hours before bed to reduce the likelihood of waking because of metabolic activity.
