The Perfect Pillow !

Nothing starts your day off better than getting a good night's sleep. And sleeping with the right pillow can help.The wrong pillow may worsen headaches, neck pain, shoulder and arm numbness, discomfort, sneezing, and wheezing.And if your pillow is past its prime, it may contain skin cells, mold, mildew, fungus, and dust mites, which make up more than half of an older pillow's weight, Breus notes.

Is it time to buy a new pillow? Experts say the general rule is to buy a pillow every 12 to 18 months. After two years, it's definitely got to go.

Some expert advice:

• If you sleep on your back: "Back sleepers need thinner pillows, so their head is not thrown too far forward." Also look for a pillow with extra loft in the bottom third of the pillow to cradle your neck.
• If you sleep on your side: Side sleepers need a firmer pillow to fill in the distance between the ear and outside shoulder.
• If you're a stomach sleeper: Look for a very thin, almost flat pillow. You may not even need a pillow for your head, but consider tucking one under your stomach to avoid lower back pain, Breus suggests.

Here's what to look for in each type of pillow filling:

• Foam: "Go by the density," Breus says. "The higher the density, the less breakdown, and the more support you will have without getting too soft."
• Memory foam: These are popular because they reduce pressure points by continuously molding and adjusting to the shape of your body as you move throughout the night. Memory foam pillows come in various shapes, including a popular contoured S-shape, which is meant to support the neck. Breus notes that memory foam material is known to make sleepers hot, and can sometimes emit an unpleasant chemical odor.
• Latex: This is the firmest type of pillow, and it resists mold and dust mites, Breus says. Latex pillows may also help with back and neck alignment, as they're often contoured for neck support.
• Wool/cotton: Wool and cotton pillows are hypoallergenic and resist mold and dust mites. Both also tend to be quite firm. So if you love a squishy pillow, these fillers aren't for you.
• Down/feather: Many sleep experts recommend these as one of the best pillows for a good night's rest. "One of the great things about down pillows is that you can move the stuffing around so that you have the most support where you need it," Bernard says. "Plus, it's soft, yet firm enough to give you the support you need."

When shopping for a new pillow, keep these tips in mind:

• Consider more than cost. "Just because a pillow costs more does not automatically make it a better pillow or the right pillow for you," Bernard says. "What matters is how the pillow feels to you. Most of the time, you can find something that works without breaking the bank."
• Try it out in the store. "If you're in a store and there's the option to lie down, do that," Breus says. If that's not an option, Breus suggests that you stand next to a wall in the position in which you like to sleep, put the pillow against the wall as though the wall were a vertical mattress, lean your head against it, and ask someone to tell you if your neck is tilting one way or another. Your neck should be in line with your spine.

Here's a quick look at some of the options:

• Cervical pillows: Available in various materials and shapes, these pillows add extra cushioning in the lower portion of the pillow to support the neck. Doctors say that occasionally they can be of some help, but a research review, conducted by the Canadian Institute for the Relief of Pain and Disability in 2007, showed insufficient evidence to recommend for or against the use of these pillows.

• Water pillows: Favored by some physical therapists and many chiropractors, these pillows use water to create your own customized level of density and support.

• Cool pillows: Touted as an antidote to hot flashes and night sweats, these pillows include a filling of tiny "beads" that absorb and whisk away head heat, leaving the part of the pillow that touches your face cool. "You lay your head on it and it's like you always have the cool side of the pillow," Breus says.
• Oxygen-promoting pillows: This pillow technology is based on studies of sock fabric that helped promote circulation in diabetes patients. These pillows use the same technology to increase oxygen content in tiny blood vessels by up to 29%. What can that do? Doctors aren't sure, but "some people have even reported a reduction in pain after using these pillows," Breus says.
• Anti-snore pillows: There is limited research showing that any particular pillow design affects snoring. But individual patient reports, and a study published in 2005, show that relief is possible in some people.
• Positional pillows: These pillows are designed for back, stomach, or side sleepers. Experts say some can be very helpful. If you choose one, look for support, comfort, and the right size for your body.
