The Science of a Good Night’s Sleep
There are four common hindrances to quality sleep: backaches, sore shoulders or hips, temperature issues, and breathing troubles. Reading this will help you understand the ergonomic features that a mattress must have to resolve these hindrances and assure deep sleep. Mattress shopping is actually buying better sleep. By understanding the quality of sleep a mattress will produce for 10 to 15 years we can determine it’s true value.
Reducing movement while we rest allows deeper levels of sleep that rejuvenates our bodies. Many factors, such as age, weight, and sleeping style, will determine what you need to sleep more motionless. However, too keep it simple, there are four things a mattress must to do for everyone. In order of importance they are: maintain spinal alignment, reduce surface pressure, regulate body temperature and resist nasty allergens.
1 ~ Maintaining spinal alignment. Backaches are produced by mattresses that don’t support your spine. The ideal position of your spine while lying is the same as it while standing. A mattress that is too hard will tend to push on your shoulder and hip while not supporting your lower back or side. Soft mattresses often sag, causing your spine to follow the curve of the mattress. Only a mattress that can conform to your body without sagging will give adequate support. This support should be felt evenly along the length of your body, especially at your waist and lower back.
2 ~ Reducing surface pressure. High pressure on your shoulder and hip causes tossing and turning because it restricts blood flow and eventually will cause these joints to ache. A mattress that conforms to the shape of your body will distribute your weight evenly and eliminate high-pressure areas. The best materials to achieve this are latex and visco-elastic (memory) foams. These foams produce even pressure over the entire surface of your body, allowing your body to relax into the deeper levels of sleep, which provide the greatest recovery for the body. This pressure can be measured scientifically to assure proper circulation.
3 ~ Regulating body temperature. Sleeping too hot or too cold will also cause tossing and turning. While we sleep, our bodies give off moisture, which gets trapped in our bedding. This dampness interferes with our body’s ability to regulate its own temperature. The best cure for this is wool, either as the top layer of the mattress or in a separate mattress pad. Wool can absorb up to one third of its weight in moisture without feeling damp. It also dissipates moisture much faster than down, cotton, or polyester. Since you are drier, you are warmer in the winter and cooler in the summer. Your heartbeat actually slows down, and you relax into deeper sleep.
4 ~ Reduce harmful allergens. Waking stuffy in the morning may indicate dust mites, mold or mildew. These thrive in a damp environment. Wool’s self-drying properties prevent the build up of mold and mildew making it very difficult for dust mites to thrive. Also, natural latex and wool produces no chemical off gassing, creating a healthier sleep environment for all, especially those who suffer with allergies or asthma.
Conventional bedding fails in two areas. First the padding, which consists primarily of polyurethane foam, will soften and show body impressions. Polyurethane foam will loose 20 to 40 % of its resiliency in ten years, causing a proportionate increase in surface pressure. Secondly, as poor quality springs inevitably weaken, the mattress sags in the middle, distorting the natural curve of the spine.
We have found no other material that can match the resiliency and the performance of latex foam. Correctly formulated latex foam will loose only 10 to 15 % of its resiliency in ten years, even in softer densities. By combining layers of foam that vary in density, optimal spinal alignment and very low surface pressure can be achieved and maintained for years with consistent performance.
Best of all you’ll never feel the movements of your sleep partner, because there is zero motion transfer and they will sleep more motionless too! (They may even wake up nicer.)
