In a recent study, adults who were allowed just five hours of sleep a night for a week continuously scored poorly on tests. Only after they slept eight hours for two nights in a row did their test scores improve. Researchers say by cutting your sleep short, you miss out on REM (rapid eye movement) sleep, which helps consolidate information and enhance memory.
Additionally, a survey conducted by the Better Sleep Council reports that “sleep deprivation” impacts alertness at work, productivity and your ability to socially interact with co-workers. The bottom line: Quality sleep is vital to your health, happiness and productivity. According to the latest research, the human body still needs 7-8 hours of sleep per night (the recommended average for adults).
Tips for healthy sleep
To improve the quality of your nightly sleep, the National Sleep Foundation recommends the following:
1. Schedule time for sleep. Just like we manage the many things on our “to do” lists, sleep is an appointment that you can not miss. When the quality of your sleep improves, so does your mood, thus the quality of your life. Tonight’s sleep can determine how your tomorrow will be, so it should be top on any daily agenda.
2. Establish a relaxing bedtime routine and create a sleep sanctuary. Wind down before bed. Take a bath, meditate, do whatever you need to do to relax and wipe away the day’s stress. If you find your mind racing while trying to sleep, keep a pad of paper next to your bed and jot down what’s on your mind. Make sure your bedroom is dark, cool and quiet and that your pillows, sleep surface and coverings provide you with comfort.
3. Exercise regularly, but finish your workout at least three hours before bedtime.
4. Avoid foods and drinks high in caffeine (coffee, colas, tea and chocolate) and alcohol a few hours before bedtime. Caffeine and alcohol disturb sleep. Nicotine may make it difficult to fall asleep and lead to fragmented sleep; those who smoke should get help to quit.
NOTE: If you suffer from chronic or severe insomnia, visit your doctor or a sleep disorders clinic to see if there is an underlying medical condition.

According to a recent study, four simple behaviors – being physically active, not smoking, drinking moderately and consuming fruits and vegetables – can increase longevity by as much as 14 years. The study surveyed 20,244 men and women (ages 45 to 79) in the United Kingdom between 1993 and 1997. The participants, none of whom had cardiovascular disease or cancer at the beginning of the study, were asked if they were nonsmokers, were physically active, had moderate alcohol consumption and ate at least five servings of fruits or vegetables a day. One point was assigned for each healthy behavior.

Researchers studying gratitude report that practicing gratitude can improve your health and well-being. Robert Emmons, Ph.D. and colleagues at UC Davis randomly divided study participants into three groups, each which made weekly entries in a journal. One group had to write about five things they were grateful for. Another group was assigned to write about five things they found annoying or irritating. And a control group was asked to list five events that affected them in some way. At the end of the three-week study, those who focused on gratitude reported feeling better about their lives overall, were more optimistic about the upcoming week and reported fewer health problems when compared to the group that focused on hassles, or the control group.
