Overview
- Nutritionist Oliver Goble warned on Thursday, May 28, 2026, that waking regularly at about 3am often reflects an underlying strain on the body rather than a random night-time rouse.
- Experts say overnight rises in stress hormones such as cortisol can keep the brain more alert and break up deeper sleep stages.
- Blood-sugar drops or swings can trigger early-morning waking by activating the body’s stress response or prompting hunger-related arousal.
- Alcohol, late heavy meals and caffeine intake earlier in the day are common, modifiable causes that fragment sleep and make early waking more likely.
- Brief awakenings are normal but the advice is to improve sleep habits and see a healthcare professional if the same-time waking persists for weeks with daytime tiredness since this commentary summarizes established mechanisms rather than new clinical research.
