Research says this is how long you should sleep

Getting 6 – 8 hours of sleep is found to be beneficial to the heart. Short sleepers have 11% greater chance of heart ailments while those who sleep more than 8 hours have a 33% greater risk.

According to the lead researcher having the odd short night or lie-in is unlikely to be detrimental to health, but evidence is accumulating that prolonged nightly sleep deprivation or excessive sleeping should be avoided. The research involved data collected from 1 million individuals, across 11 studies. Authored by Dr. Epameinondas Fountas of the Onassis cardiac surgery center in Athens, it was recently presented at the European Society of Cardiology Congress in Munich.
