I have been doing a number of presentations and workshops of late and asking people how much sleep they get a night.
The current research suggests that 7.5hrs to 9hrs is ideal for about 80% of the population. Some can get a way with less, and some need more.Far too many people put their hands up for less than 7hrs sleep and many of these have less than 6hrs sleep a night – consistently. You just cannot sustain optimal living on limited sleep.
The real cost
Many people ‘think’ they can function on less sleep, but may be unaware of the real consequences. For instance many may have less positive health, reduced resilience to illness, and slow recovery from sickness.
But one of the worst consequences, I suspect, is they are achieving less than they are capable of. I think if they had more sleep of a night-time they would be able to perform more effectively, efficiently and creatively. One of the many results of getting more shut-eye of a night-time.
