*SAP India CEO Ranjan Das Dies After Gym Workout*     
Ranjan Das, CEO and MD of SAP-Indian subcontinent died after a massive cardiac arrest in Mumbai recently.
One of the youngest CEOs, he was only 42.
*What killed Ranjan Das?*
He was very active in sports, was a fitness freak and a marathon runner.
After his workout, he collapsed with a massive heart attack and died. He is survived by his wife and two very young kids.
It was certainly a wake-up call for corporate India. However, it was even more disastrous for runners.
The question arises as  to why an exceptionally active, athletic person succumbed to a heart attack at 42 years of age.
*What is the real reason?*
Everyone missed out a small line in the reports that *Ranjan used to manage with 4-5 hours of sleep.*
In an earlier interview of Ranjan on NDTV in the program ‘Boss’ day out’, *Ranjan Das himself admitted that he sleeps less and would love to get more sleep.*
*Short sleep duration (<5 or 5-6 hours) increases risk for high BP by 350% to 500%* compared to those who slept longer than 6 hours per night.
*Young people (25-49 years of age) are twice as likely to get high BP if they sleep less.*
*Individuals who sleep less than 5 hours a night have a 3-fold increased  risk of heart attacks.*
Just one night of sleep loss increases very toxic substances in body such as Interleukin-6 (IL-6), Tumour necrosis factor-alpha (TNF-alpha) and C-reactive protein (CRP). They also cause cancer, arthritis and heart disease.
Sleeping for <=5 hours per night leads to 39% increase in heart disease.
Sleeping for <=6 hours per night leads to 8% increase in heart disease.
*What is ideal sleep?*
In brief, sleep is composed of two stages: REM (Rapid Eye Movement) and  non-REM. The former helps in mental consolidation while the latter helps in physical repair and rebuilding.
*No wonder when one wakes up with an alarm clock after 5-6  hours of sleep, he/she is mentally irritable throughout the day (lack of REM sleep).*
And if somebody has slept for less than 5 hours, the body is in a complete physical mess (lack of non-REM sleep), the person is tired throughout the day and immunity is way down.
Barring stress control, Ranjan Das did everything right: eating proper food, exercising, maintaining proper weight. But he missed getting proper and adequate sleep, minimum 7 hours. That killed him.
*We are playing with fire if we are sleeping less than 7 hours even if we have low stress.*
Do not set your alarm clock under 7 hours.
Ranjan Das is not alone.
Do Share it with all the Good People In ur Life…?
