Tamil actor Ajith Kumar, 54, a racing car buff, recently reflected on his various commitments, which leave very little time for him to sleep. “Sometimes even less (sleep)…Just last night, I only slept for two hours,” Ajith recently admitted.

On being asked why, he told The Hollywood Reporter India, “I don’t know. I ask myself this question every day. Because there is so much that I need to think of. My career, putting a project together, and racing. Racing is a very expensive sport. I have not had a sponsor. And I am seeking a purpose, not to enhance my personal wealth. I am trying to put it back into the sport, which I see has a lot of potential. Yes, I love the sport, but I know this sport has got a lot of potential for the drives, the brands, and manufacturers. So, I am knocking on every door. So, that’s one part of me. There are so many other things that I am thinking of (which keep me awake). I am grateful.”

But how do some people manage to function well on less sleep every night, while some just cannot handle it?

We turned to Dr Aarti Ullal, physician and diabetologist, Gleneagles Hospital Parel, Mumbai, to gather some insights. “Some people seem to function well on very little sleep, often getting by with just 4–6 hours a night. This ability can be influenced by genetics, lifestyle, and adaptability,” said Dr Ullal.

However, for most people, consistently sleeping less than 7 hours can cause fatigue, mood changes, and decreased focus, even if they don’t notice it right away, she added.

“Those who manage on less sleep often have strong motivation, disciplined routines, and efficient sleep quality, meaning they reach deep, restorative stages faster. Factors like healthy diets, regular exercise, stress management, and consistent sleep schedules also help improve sleep efficiency,” said Dr Ullal.

Still, it’s important to note that being used to less sleep doesn’t mean it’s healthy. The expert said that chronic sleep deprivation increases the risk of heart disease, diabetes, obesity, and weakened immunity.

“People who appear fine on short sleep may actually be coping with subtle health declines over time. While some individuals can function well on less sleep due to genetics or strong discipline, most people need 7–9 hours to maintain long-term health, energy, and mental well-being,” said Dr Ullal.
