Memory foam is good for people with orthopaedic problems, as back pain can be diminished because of the way the mattress works. An explanation of the process that happens when you sleep on it will be outlined below.

Memory foam is made of layers of foam, the top of which is really absorbent to body heat. When you lie on it, the heat in your body will soak into this layer and mould the foam around you. The layers of foam underneath will remain at the lower temperature, and are firmer, so the mattress does not sag. This will consequently be more supportive to your spine that usual mattresses, as normal springs can cause your spine to have to be misaligned, by being curved at a slight angle. This can cause aches and pains, so it is useful to have a memory foam mattress for your bed, to prevent any mild pains that may be caused by this. The memory foam easily springs back into place once you get off it, but can retain the shape when heat is applied. In this way, memory foam is superior to your standard sprung mattress.

While it may be beneficial to health primarily in this way, memory foam also harbours less allergens than normal and so allergic reactions or inhalations of dust spores and suchlike will be reduced if you get this kind of mattress. This can be another big benefit to health, and can be particularly good for those who are in bed a lot, as bed lice are unlikely to get into the memory foam. It is also good for hayfever sufferers, as if you have a bedroom window open in the pollen season, the bed will not let the pollen get into it.

There are negatives to this kind of mattress: but these are generally to do with how it differs to a sprung mattress, which many people are used to. For example, because of the way it works, memory foam can feel warm and so, in summer, you may feel like it is harder to remain cool in bed. The flexible nature of the foam can also take a while to get used to, but this does happen after the initial breaking in period and is just like any new product when you use it for the first time.

Memory foam is available in toppers for usual mattresses if the price puts you off investing in a mattress, but it is definitely a worthwhile investment. Toppers will need to be replaced every few years, as consistent heavy weight can crush the foam and mean that it eventually does not mould as well. A mattress will not have this problem really though, and so because of the greater longevity, it is more sensible to buy a mattress in one go, than to pay for toppers more regularly, as memory foam is definitely worth having just because of the health benefits. ]]> http://www.articlecabi.net/health/sleep/good-sleep-is-best-medicine.html http://www.articlecabi.net/health/sleep/good-sleep-is-best-medicine.html Thu, 28 Jan 2010 23:05:36 -0500 Sleep is a natural part of everybody's life. like diet and exercise, Sleep is important for our minds and bodies to function normally , it is not an option. During sleep many of the body's major organ and regulatory systems continue to work actively. Some parts of the brain actually increase their activity dramatically, and the body produces more of certain hormones. In fact, sleep appears to be required for survival
How we fall asleep?
One or the other time many of us might have got this question in our mind about " How do our bodies know when it is time to sleep?" . well here is the answer .
We all have an internal circadian clock that provides cues for when it is time to sleep and time to wake. This clock is sensitive to light and time of day, that is why having a good bedtime routine and a quiet dark place to sleep is so important. At the same time, a chemical messenger called adenosine builds up during the day as our bodies are busy using energy. The more adenosine builds up in the brain, the sleepier you will feel. Adenosine combined with the circadian clock sends a powerful message of sleepiness to your body.
STAGES OF SLEEP:
• Stage 1 (Drowsiness)
• Stage 2 (Light Sleep)
• Stages 3 & 4 (Deep Sleep)
• REM sleep (Dream Sleep)

Now comes the question of how many hours of sleep is needed for an individual , this is a valuable question to be thought about ,because many people in this current competitive and fast paced generation had their own strategies and try to impose this upon others. Some people find that they only need 5-6 hours of sleep, while others need 10-11 hours for optimal performance. So lets find how much is needed in real to every one.
How much sleep is enough?
Each person's sleep requirement is different , it is important to consider how much sleep you need on an individual basis. However the average adult functions best with 7-8 hours of sleep a night
Newborns: neither diurnal or nocturnal, sleep-wake cycles are frequent and evenly spaced during any 24-hour period; sleeping for 3-4 hours, waking for 1-2 hours
Infants: About 16 hours per day of sleep
First year: At one year the infant typically sleeps about 10-12 hours. more at night with a couple of naps in the early and late afternoon
By age 4-5: the child has lengthened the nocturnal period to about 11-12 hours with one nap in the afternoon.
Ages 6 to 9: about 10 hours of sleep
Ages 10 to 12: about 9 hours of sleep
Teenagers: About 8-9 hours of sleep
For adults: 7 to 8 hours a night appears to be the best amount of sleep, although the amount ranges from 5 hours to 10 hours of sleep each day depending on the individual
Senior adults: they have further shortened sleep requirements. But it is now thought that this is only because they tend to get sleep apnea, or musculoskeletal pain which disturbed their sleep.
NOTE: Boston University School of Medicine found that sleeping less than 6 hours or more than 9 hours a day had an increased incidence of diabetes, compared to those who slept 7-8 hours
