In a recent study by the Centers for Disease Control (CDC), one in nine adults reported never getting enough sleep during the previous month.

Some 11 percent said there was not one single day during the previous month that they were able to get enough sleep. Most adults need seven to nine hours of sleep each night. However, it is possible to determine your sleep needs. Another 16.8 percent said they had gotten insufficient sleep for more than half of the month.

The data were collected as part of the CDC's Behavioral Risk Factor Surveillance System, which surveyed 404,000 people in all 50 states via telephone. Experts agree that insufficient sleep can have major health consequences.

As the year draws to a close, it may be time to use up that money you set aside in your flexible spending account before it's too late.

Flexible spending accounts are an option provided by employers for setting aside pre-taxed income that can be used for anticipated health expenses. These expenses can be quite varied, and may include office copayments, medications, or equipment used to treat sleep disorders. Unfortunately, any money that is not used by the end of the year is lost.

So if you have money sitting in your flexible spending account waiting to be used, now is the time to act.

It is sometimes difficult to objectively characterize something like sleepiness. We know it when we feel it, but it may be something that is difficult to put a number on.

The Epworth sleepiness scale is devised to do just that. It is routinely used to assess the degree of an individual's sleepiness. This is done by presenting common situations and asking how likely you are to fall asleep in them.

This can be a useful measure to establish a starting point in those with sleep disorders and also to monitor a response to treatment over time.
