what is the optimum sleep time

[rauland]

My sleep log shows about 60% sleep efficiency. What is considered optimum?

Sometimes I have a higher efficiency than others. It depends on how restless I am.

Sixty percent is not good sleep. You may want to evaluate your caffeine intake. People often say that they can drink caffeine before bed and still go to sleep.  The problem is that when that occurs, your sleep is neither deep nor restful.  Try to experiment with it.   Because of the way that caffeine interacts with the body, if you go to bed at 10 pm, then the last caffeine that you should have is at 2:30.  The other concern is that if you have a large dose of caffeine from noon to 2:30, it would also cause you to have poor sleep. I hope that this helps.

It didn't take many weeks of recording my sleep patterns to notice a trendl.  Overall my sleep is typically really good (90%) except if I eat late in the evening or drink anything 'stronger' than water.
