If you're battling blood pressure problems, you don't need another med -- you just need better sleep... and that doesn't necessarily mean more sleep.

"Better" sleep is slow-wave sleep -- the deep sleep that helps to refresh our bodies and restore our minds. And now, a new study finds that people who miss out on it aren't just tired, forgetful, and irritable -- they have a dramatically higher risk of hypertension, too.

Researchers checked the BP levels and monitored the sleep habits of 784 senior men on two occasions, three and a half years apart.

They found that men who spend less than 4 percent of the night in slow-wave sleep were 83 percent more likely to develop hypertension between the two tests than men who spend at least 17 percent of the night locked inside that deepest of slumbers.

The men who got the low-quality sleep were also more likely to get less overall sleep, wake up more often, and even suffer from sleep apnea.

So how much quality sleep are you getting? There's no way to know for sure without spending a night in a sleep lab. But one way you can tell on your own, right now, is to just see how you feel in the morning.

If you wake up feeling lousy, odds are you're not getting enough. Poor sleep can do so much more than raise your blood pressure. Lack of sleep and low-quality rest can boost the odds of everything from cognitive decline to an early death.

You definitely don't want any part of that – but don't rush off to your doctor and beg him for sleep meds, either, because there are natural solutions that can help you to get the best rest of your life.

One recent study found that seniors can overcome sleep problems with the help of talk therapy in as little as two in-person sessions and two follow-up phone calls. (Read about it here.)

Other studies have found that you can get relief by making simple lifestyle adjustments -- like cutting back on late-day caffeine -- or easy nutritional additions, such as a calcium and magnesium supplement before bedtime.
