Dr. Narander Singla, lead consultant in internal medicine at CK Birla Hospital, Delhi, emphasizes that the ideal sleep duration for most adults is a "sweet spot" of 7 to 9 hours per night, supporting optimal rest, memory consolidation, and physical recovery. He stresses that individual needs vary, and personalizing one's sleep routine within this window is crucial, as factors like age (older adults may need 7-8 hours) and individual variations influence requirements. Dr. Singla also highlights that sleep quality is as vital as quantity, noting that disruptions, stress, or an uncomfortable environment can negate the benefits of sufficient sleep. This 7-9 hour range is considered ideal because it significantly enhances both physical health (immune function, weight management) and mental well-being (cognitive performance, focus, memory, emotional regulation), ultimately improving daily performance and energy levels. The key is to find one's personal "sleep sweet spot" and prioritize high-quality, uninterrupted rest for a refreshed and focused start to the day.
