Sleeplessness, commonly known as insomnia, is not a disorder in itself but a symptom that may point to deeper psychological, medical, or lifestyle-related issues. On a psychological level, conditions such as anxiety, depression, chronic stress, or past trauma can significantly disrupt sleep patterns, making it hard to fall or stay asleep. Medically, issues like chronic pain, asthma, hyperthyroidism, or gastrointestinal reflux can also interfere with restful sleep. Additionally, lifestyle habits such as consuming too much caffeine, inconsistent sleep routines, late-night screen use, or working irregular shifts can all contribute to poor sleep quality. While it’s normal to experience an occasional sleepless night, persistent insomnia that affects your daily life, mood, energy levels, or concentration should not be ignored. In such cases, it’s important to consult a healthcare professional — especially a psychologist, psychiatrist, or sleep specialist — to identify and address the root cause, rather than just treating the symptom. Early intervention can prevent long-term health consequences and significantly improve overall well-being.
