To get out of bed in the morning without difficulty, you simply need to force yourself to get up the moment you open your eyes.

This advice is based on the idea of overcoming sleep inertia through immediate action. Scientifically, what one feels upon waking is often linked to sleep inertia, a temporary physiological state of reduced alertness (Meta-analysis, Journal of Sleep Research). Forcing oneself to get out of bed can effectively interrupt this cycle, but it does not address the root cause if waking up is difficult (lack of sleep, shifted circadian rhythm, or poor sleep quality). The assertion that this works "every time" is exaggerated, as it ignores individual sleep needs and potential underlying disorders. An observational study shows that schedule regularity has a much more lasting impact on the ease of waking up than sheer willpower. In summary, it is a useful behavioral technique for breaking the habit of lingering in bed, but it remains a superficial solution.
