Whether the reason is anxiety, depression, pain, or some other factor, millions of people experience some form of insomnia. Even something as simple as changing the clocks for daylight-saving time can interfere with sleep patterns. It can make you fall short of the eight hours necessary to be creative and energetic-and to keep your immune system functioning properly.
Why do you need at least seven to eight hours of sleep? REM (rapid  eye movement) sleep, which takes place throughout the night, occurs for  the longest periods at the end of the sleep cycle. This is because the  brain replenishes its supply of neurotransmitters, such as noradrenaline  and serotonin, which are crucial for new learning and retention as well  as for mood when we get proper sleep.
   
If you're sleep deprived, try these simple steps for snoozing:
Before Bedtime: It's important to establish a sleep  routine and stick to it. Choose a regular bedtime and preface it with a  warm bath, adding a few drops of lavender oil to the water. Avoid  stressful stimulation from the evening news or violent movies, and  listen to soothing music instead. If you have to get up during the  night, don't turn on the lights. Doing so throws off your internal  clock. And never try to sleep with cold feet.
   
Avoid Stimulants: Stay away from caffeine, alcohol, and  sugar, as well as foods that are spicy or high in fat or salt,  particularly in the afternoon and evening. Cold medications and tobacco  should also be eliminated. Stick with foods rich in nutrients, but don't  eat anything for at least two hours before bedtime unless you need a  protein snack to deal with a low blood-sugar problem.
      
Sleepy Time Snacks: There's a reason everyone wants to  take a nap after a big meal. Food rich in protein is loaded with the  amino acid tryptophan that manufactures serotonin, which is crucial for  sleep.
   
Tryptophan isabundant in poultry, fish, dairy, eggs, bananas, figs,  pineapples, nut butter, tuna, and whole-grain crackers-all good foods to  eat in the evening.
   
Consider Vitamins: In addition to consuming foods that  contain tryptophan, increase your intake of edibles high in vitamin B  complex (nutritional yeast, egg yolks, fish, wheat germ, legumes, and  whole grains) and vitamin C (dark, leafy greens and tart fruits). These  vitamins help in the conversion of tryptophan to serotonin, so a good B  complex supplement along with at least 200 mg of vitamin C is sleep  insurance. A calcium/magnesium supplement can
also be effective for relaxing tense muscles.
   
Helpful Herbs: A cup of German chamomile tea is a  soothing way to end the day. Used for more than 1,000 years, valerian  (Valeriana officinalis) has a  ranquilizing effect, induces sleep, and  improves sleep quality.
    
Hops (Humulus lupulus) has a calming, sedating effect, and St. John's  wort enhances both serotonin and melatonin, helping you stay in deep  sleep longer. Passionflower is also mildly sedating.
   
Kava (Piper methysticum) relieves underlying causes of insomnia:
anxiety, restlessness, and stress. Don't take kava for more than three  months, however. Kava should not be used by anyone who has a liver  problem, takes medication that has an adverse effect on the liver, or  consumes alcohol regularly.
   
Expend Energy: Besides toning your body, exercise is  good for your mind. A walk, a run, a workout at the gym-they all produce  endorphins, which help ease depression and improve sleep. But observe  the two-hour rule by stopping physical activity at least two hours  before bedtime.
      
Stress Busters: Take time to smell the flowers. Go for a  stroll, meditate, read a poem, fly a kite, listen to music.  Relax-you've earned it. You'll be just a nod away from sweet dreams.
   
Shift Work: If you're one of the millions of people who  don't work a typical 9-to-5 business day, you're most likely fighting  your natural sleep-wake pattern. Shift workers in hospitals, on police  forces, and in manufacturing and transportation jobs are working all  night while the rest of the world is sleeping. Then they try to sleep  during daylight hours when everyone else is awake.
    
The human body works on a 24-hour cycle of waking and sleeping, its cues  from nature's cycle of light and darkness. Since sleepiness hits most  of us between midnight and 6 a.m., people who are working during those  hours are disrupting their normal sleep cycle and may
have difficulty falling asleep once they do get home.
   
The following tips may help prepare you for sleep:
- Wear wraparound sunglasses if you drive home in daylight.
- Ask others not to perform noisy household chores like vacuuming or running the dishwasher.
- Unplug the telephone.
- Darken the bedroom with curtains or shades and install carpeting to absorb sound.
- Wear earplugs.
- Turn on a fan or some other white noise to block sound.
Stick to your sleep schedule, even on weekends.
