A Lifetime of Little Sleep
Legendary playback singer Asha Bhosle, who passed away on April 12, 2026, in Mumbai due to exhaustion and a chest infection, followed an astonishing sleep
schedule for most of her life. As revealed in a 2024 interview, she consistently slept only three to four hours per night, a habit that began around age 15 when she started her film singing career. Living in Borivali meant early commutes, necessitating very early wake-up times, to which she became accustomed. This demanding routine, coupled with the essential two hours required daily for vocal practice (riyaaz), left little room for extended sleep. Bhosle herself explained that this intense schedule meant sleep was a luxury she could rarely afford, leading her to develop this unique and demanding lifestyle from a very young age. She even mentioned resorting to sleep aids to catch any rest when her work schedule allowed for a slightly later wake-up, typically not past 7 AM on non-working days.
The Body's Plea
Dr. Sunil Kumar K, a specialist in Pulmonary and Sleep Medicine, highlights that consistently sleeping less than the recommended 7-9 hours can detrimentally impact nearly every bodily system. Sleep is crucial for the brain and body's repair, restoration, and energy replenishment processes. Insufficient sleep deprives the brain of adequate time to clear waste products, potentially leading to long-term cognitive issues such as impaired memory, concentration, and thinking abilities, and might even elevate the risk of dementia later in life. Furthermore, it disrupts hormonal balance, increasing stress hormones like cortisol, which can manifest as heightened anxiety, irritability, and persistent fatigue. The implications extend to metabolic health, affecting blood sugar regulation and increasing diabetes risk, while also weakening the immune system, making individuals more susceptible to infections and prolonging recovery times.
Long-Term Health Risks
The ramifications of chronic sleep deprivation, as outlined by Dr. Kumar, extend to cardiovascular health and metabolism. The heart, like other organs, requires rest and recovery, which is compromised by inadequate sleep, potentially increasing the risk of heart disease, high blood pressure, and stroke over time. Metabolism can also suffer, either slowing down or becoming irregular, which can contribute to weight gain or difficulties in maintaining a healthy weight. Even skin health is affected; reduced sleep hampers collagen repair, accelerating the appearance of aging signs such as wrinkles and dullness. Emotionally, prolonged sleep loss can exacerbate conditions like depression, lead to mood swings, and generally diminish energy levels and overall physical performance, painting a stark picture of the body's struggle when deprived of sufficient rest.
Adapting and Enduring
While the adverse effects of sleep deprivation are significant, Dr. Kumar acknowledges that a small subset of individuals may exhibit an unusual ability to adapt to lower sleep durations. This adaptation can stem from genetic predispositions or long-term conditioning, allowing some to function without outwardly apparent symptoms. However, medical professionals caution that even in these rare cases, internal stress and health risks might silently accumulate over time. Factors like a healthy lifestyle, maintaining a consistent daily routine, possessing strong mental resilience, and adhering to good nutrition can help mitigate some of the negative impacts. Despite these compensatory strategies, they cannot fully substitute the fundamental need for adequate sleep. Experts emphasize that while these cases are intriguing, they should not be considered the norm, and the vast majority of people should strive for the recommended 7 to 9 hours of sleep nightly to safeguard their long-term health and overall well-being.
