You wake up with a stuffy nose.
Dust mites are microscopic insects that feed on mildew-degraded house dust. Many people are allergic to these tiny bugs. Dust-mite allergy symptoms include a runny nose, sneezing, watery eyes, and an itchy mouth or throat.
If you wake up with those symptoms, your mattress may be to blame. Along with washing your pillowcases and sheets at least once a week to rid them of mites and other allergens, buying an allergen-blocking mattress could also help, the research suggests.
Your libido is low.
A non-existent sex drive is one of the sneakier signs that you’re not getting good-quality sleep. And both night sweats and sleep disturbances—caused in some cases by a too-warm sleeping environment—are linked to a loss of libido.
Getting a mattress with a cooling technology like Real Sleep by Real Simple, will pull heat away from the body, safeguard your ZZZs—and your sex drive.
Your skin doesn’t look (or feel) so hot.
Poor-quality sleep is associated with a surge in stress-related hormones like cortisol and the systemic inflammation it causes can promote wrinkles, a loss of skin firmness and elasticity, dull skin, and itchy skin conditions like eczema.
Old mattresses may be one cause of poor sleep and stress. Replace your old mattress, reduce stress and watch your best skin emerge in as little as four weeks!
It takes you an hour or more to fall asleep.
One measure of sleep quality is something sleep researchers call “sleep onset latency”—or the amount of time a person lies in bed before finally drifting off.
While you may (rightfully) blame your inability to fall asleep on things like your bedtime smartphone habit, or your messy room, it could also be that your mattress has become hard with age.
Especially among elderly people, switching from a “high firm” mattress to a “medium firm” mattress, the average time it takes them to fall asleep falls from an average of 67 minutes to just 21 minutes. Measures of neck and back pain also drops more than 50% after sleeping on a medium-firm mattresses for four weeks.
