Dr. Prashant Saxena, a sleep specialist at Fortis Hospital in Vasant Kunj, highlights the detrimental effects of irregular sleep schedules on health. Patients often present with issues like high blood pressure, poor sugar control, and fatigue, which are exacerbated by inconsistent sleep patterns. The body's circadian rhythm, which regulates various bodily functions, is disrupted by erratic sleep, leading to serious health risks including heart disease, cognitive decline, and metabolic issues. Dr. Saxena offers a step-by-step guide to improving sleep, starting with establishing a consistent wake-up time, followed by exposure to morning sunlight, and reducing caffeine intake in the afternoon. He emphasizes the importance of creating a calming pre-sleep routine and maintaining an optimal sleep environment. If lifestyle changes do not improve sleep quality, he advises consulting a sleep specialist to rule out underlying medical conditions.
