Sleeping less than 7 hours a day?

Today I got a mail from someone in the department of metallurgy and material science, IIT Bombay which emphasizes on the need of good sleep. In fact he forwarded the mail to all the IIT B people. It's a very good time to remind all the students with the probable consequences of not having good sleep since end semester examination has already started and most of the students might be planning night outs to prepare for examination. The fellow who has sent the mail seems to have collected a few very important points:

1. Short sleep duration (less than 5 or 5-6 hours) increased risk for high BP by 350% to 500% compared to those who slept longer than 6 hours per night. Paper published in 2009. And high BP kills for sure.
2. Young people (25-49 years of age) are twice as likely to get high BP if they sleep less. Paper published in 2006.
3. Individuals who slept less than 5 hours a night had a 3-fold increased risk of heart attacks. Paper published in 1999.
4. Complete and partial lack of sleep increased the blood concentrations of High sensitivity C-Reactive Protein (hs-cRP), the strongest predictor of heart attacks. Even after getting adequate sleep later, the levels stayed high.
5. Just one night of sleep loss increases very toxic substances in body such as Interleukin-6 (IL-6), Tumour Nacrosis Factor-Alpha (TNF-alpha) and C-reactive protein (cRP). They
increase risk of many medical conditions including cancer, arthritis and hear disease. Paper
published in 2004.
6. Sleeping for less than or equal to five hours per night leads to 39% increase in heart diseases.
Sleeping for less than or equal to 6 hours per night leads to 18% increase in heart disease. Paper
published in 2006.

The fellow has also pointed out the possible region behind the sudden death of a Mumbai based
CEO of some MNC as the lack of sleep. I really appreciate the effort made by him. I hope the IIT junta will pay a little attention to it.
