Managing Director of Indian operations of a large IT company died after a massive cardiac arrest in Mumbai recently at the age of 42. He was very active in sports, was a fitness enthusiast and a marathon runner. In an interview he said that he managed with 4-5 hours of sleep and admitted that he would love to get more sleep. He did everything right: eating proper food, exercising, maintaining proper weight. But he missed getting proper and adequate sleep of minimum 7 hours every day. And that killed him.
Sleep helps your brain to work properly. While you’re sleeping, your brain is preparing for the next day. It’s forming new pathways to help you learn and remember information. Our bodies regulate sleep in much the same way that they regulate eating, drinking, and breathing. This suggests that sleep serves a similar critical role in our health and wellbeing.
Cutting sleep from seven to five hours a night nearly doubles the risk of death from all causes and in particular cardiovascular disease.
