Everyone knows sleep is important, but until recently no one knew exactly why.
Now research shows that waste products from the brain’s metabolism accumulates in the fluid surrounding nerves during the day, and then gets flushed out and eliminated when you sleep. The fluid is called cerebro-spina fluid (CSF), and the study found poor sleep was associated with a buildup of a substance (b-amyloid) in CSF associated with Alzheimers.
A supportive mattress makes a difference in how well you sleep. Health professionals generally recommend a firmer sleep surface, but comfort is an individual preference. There’s a lot of new bedding options, like high quality foam and memory foam mattresses that expand on delivery, some with intricately designed layers for pressure point mapping and temperature-control.
Be sure whatever type of mattress you use that you have the correct sleep foundation. With newer sleep technology box springs are often replaced with slatted and other mattress foundations. It’s important to choose the correct foundation for your mattress to create the best sleep posture and so that the mattress cools, wears correctly and allows for sufficient air flow.
If your mattress sags (doesn’t provide adequate support), is too firm (you notice painful pressure points), sleeps too hot (tossing and turning) it’s likely time to shop for a new mattress.
