In this informative video, Dr. K. Ramesh, a Professor of Psychiatry, explores the multifaceted causes of insomnia and sleep disorders, emphasizing that poor sleep is often a symptom of underlying issues rather than a standalone condition. He discusses various contributing factors, including psychological stressors like depression and anxiety, medical conditions such as sleep apnea and restless leg syndrome, and lifestyle habits like substance use or excessive screen time. Dr. Ramesh highlights the critical importance of identifying the root cause—be it respiratory, mental, or neurological—before prescribing treatment, while also warning against the dangers of becoming addicted to sleep medications like benzodiazepines. To help viewers improve their sleep naturally, he provides practical “sleep hygiene” tips, such as maintaining a consistent biological clock, using the bed only for sleep, avoiding stimulants like caffeine after sunset, and incorporating relaxation techniques like warm baths.
