What Causes Insufficient Sleep?

Humans spend approximately one-third of their lives sleeping—a seemingly substantial amount of time. Yet, for some individuals, fatigue and sleep insufficiency persist regardless of when or where they rest. While a small minority experience unexplained chronic sleep insufficiency, the majority of cases stem from poor sleep quality or inadequate sleep duration. So, what causes persistent feelings of sleep insufficiency? Let’s explore this further.

Causes of Persistent Sleep Insufficiency

Persistent sleep insufficiency may result from excessive physical or mental fatigue, heavy manual labor performed the previous day or over several preceding days, or consecutive nights of sleep deprivation. It is also essential to consider suboptimal health status (sub-health), psychiatric disorders, and chronic debilitating diseases. Constitutional weakness or general physical debility may likewise contribute to ongoing sleep insufficiency. Additionally, elevated body temperature, blood pressure fluctuations, and—particularly—neurological disorders may underlie insufficient rest. In such cases, diagnostic evaluations—including brain MRI, electroencephalography (EEG), and comprehensive neurological assessment by a specialist—may be warranted.

From a Traditional Chinese Medicine (TCM) perspective, treatment may focus on strengthening the Spleen and augmenting Qi, regulating emotions, invigorating the mind, soothing the Liver, resolving phlegm, harmonizing Qi and Blood, restoring balance among the internal organs, and correcting Yin-Yang imbalances. We recommend consulting a physician at a hospital for thorough evaluation and diagnosis, followed by targeted pharmacological therapy based on the confirmed etiology. In daily life, ensure adequate rest—ideally taking a 10-minute break after every hour of work—and incorporate simple chest-expanding exercises. Maintain a balanced, nutritious diet as well.
