There aren't too many ways to survive a bullet hurtling toward your heart. You could be wearing a Kevlar vest (unlikely), possess bona fide Matrix moves (even more unlikely), or watch in stunned silence as the hand of God reaches down and miraculously plucks the projectile out of the air (not gonna happen unless you're in a Monty Python movie).

But there's an upside to this depressing scenario. Actually, make that two. First, the lethal round you need to worry about moves quite slowly: It's called heart disease. Second, you can count on at least 30 ways to survive it.

We've collected a whole slew of simple, effective strategies for safeguarding your heart health. You don't have to adopt all of these lifesavers, but give each one a try to see if you can stick with it for the long haul. Who knows? You just might dodge a bullet.

Love Her Two Times

Men who have sex once a month or less have a risk of developing heart disease that's 45 percent greater than that of guys who do it two or three times a week, a study in the American Journal of Cardiology reveals. Sex may protect your cardiovascular system like a clothed workout does, the researchers say.

Work In Some Walnuts

They're the alpha nuts in terms of alpha-linolenic acid, an omega-3 fat that fights inflammation, says Dr. Larry Santora, medical director of the Dick Butkus Heart and Vascular Screening Center in Orange, California. Yale researchers report that eating about a half cup of walnut halves a day can improve blood vessel function.

Keep the Beat

Tomorrow morning, before you fumble to find your slippers, find your pulse. Then log your beats per minute (bpm), says cardio-thoracic surgeon Dr. Pierre Theodore, vice chairman of the medical advisory board at Grand Rounds. Healthy guys should be at or below 70 bpm. If your rate rises higher for a week or more, call your doctor.

Heart disease is America's No. 1 killer. But know what's fact and fiction with these 5 Heart-Health Myths to Stop Believing.

Avoid Dirty Air

Inhaling ultrafine pollution particles can thicken the wall of your carotid artery, predisposing you to heart attacks, say University of Washington researchers. Particle levels peak in the early morning in winter, a study in Atmospheric Environment reports, so save outdoor runs or rides for the afternoon.

Be a Bean Counter

Pass on the potatoes and spoon out the legumes. People who ate 1 cup of fiber-rich lentils, beans, or chickpeas a day reduced their systolic blood pressure by 4 mm Hg after three months, according to a study in Archives of Internal Medicine. Add black beans to salads, cook lentils into a curry, or scoop an extra serving of pinto beans into chili.

Even if you have the will to eat more fiber, you almost certainly don't have the way. Use this plan for smuggling more roughage into your life.

Come to Grips with BP

As little as four weeks of handgrip training can lower your blood pressure by about 10 percent, a meta-analysis in the Journal of Hypertension reports. The researchers say the exercise creates "shear stress," which improves blood vessel function. Try four two-minute contractions with each hand. Rest for about a minute in between.

Start Scrambling. . .

. . .and stop thinking that eating eggs raises your LDL (bad) cholesterol. In fact, Brazilian research suggests a link between egg consumption and clearer coronary arteries. One guess is that the yolk's payload of vitamins E, B12, and folate may be the key. Just stop at four eggs a day to limit the calories.

Research finds that weight-training improves the quality of your "good" HDL, lowering heart attack risk. Find out how to improve your cholesterol today.

Run the Numbers

Choose an exercise to do weekly—say, a 2-mile run—and just afterward, log your time and your heart rate. Call your doc if you notice major changes—for instance, a heart rate of 185 bpm after a workout that typically takes you to 165 in the same time. That can signal an issue, like clogged arteries or a weakened heart, Theodore says.

Be a Breath Man

Stop and take a long, slow breath. Better yet, take six breaths in 30 seconds. Doing this can lower your systolic blood pressure by as much as 4 mm Hg within minutes, a study in Hypertension Research found. Some research suggests that if you practice this deep breathing consistently, the pressure-lowering effects can last over time.

Sweat Out Burnout

Don't let your job be the death of you: Work-related exhaustion increases your heart disease risk, a study in Psychosomatic Medicine shows. So hit reset: In a Swiss study, men suffering from burnout slashed their symptoms by up to 57 percent by doing cardio exercise just two or three days a week.

Say F.U. to the Flu

On top of its virus-fighting powers, the flu vaccine nearly halves your risk of heart attack, suggests a study in the journal Heart. That may be because influenza triggers an autoimmune response that battles the virus but also produces inflammation that can clog arteries. Visit flushot.healthmap.org to find vaccination sites in your area.

Hit the Sack. . .

Compared with solid sleepers, insomniacs face a 45 percent increased risk of heart attack, according to a study from Norway. Just 30 minutes of exercise three times a week can boost your sleep. But be patient—the benefits can take months to kick in, say Northwestern University researchers.

. . .but Don't Sleep In

There is such a thing as too much sleep: People who log 10 or more hours a night have an elevated risk of heart disease, according to a study in the journal Sleep. One explanation: Snoozing too much may be linked to weight gain and poor mental health. If you can't keep your z's in the healthy range (seven to nine hours), see your doc.

Go on a Trans Fat Fast

Columbia University scientists say you can significantly reduce your LDL-particle number (a marker of cardio risk) by cutting your trans fat intake by just 1 percent for a year. These fats are being phased out of many products, but they're not gone. For example, they're in butter-flavored Pop Secret popcorn and Land O'Lakes margarine.

Pig Out on Potassium

A CDC study found that consuming an extra 1,000 milligrams of potassium every day can reduce systolic BP. Bananas pack about 420 milligrams, and you can also find the mineral in sweet potatoes (540 milligrams per baked medium spud) and cooked yellowfin tuna (450 milligrams in a 3-ounce serving).

Charge Solar Cells

Scientists in Scotland found that 20 minutes of UV exposure can increase your body's production of nitric oxide, which lowers blood pressure. You can soak up some sun for 10 minutes twice a week, but check with your dermatologist first if you're fair-skinned or have had skin cancer, says Dr. Joshua Fox, of Advanced Dermatology P.C.

Try the Silent Treatment

For each 10 decibels of traffic noise near your home, your heart attack risk rises 12 percent, say scientists in Denmark. At night, use earplugs, such as the Howard Leight Quiet Multiple-Use Earplugs ($5 for 10, howardleightconsumer.com).

Collar Cardiac Trouble

Dog owners tend to have lower blood pressure than Fido-free folks, according to a study in Circulation. Not ready to commit? Walk a friend's pooch a few times a week, says Dr. Richard Krasuski, a Cleveland Clinic cardiologist.

Join the Breakfast Club

In a recent Harvard study, men who typically skipped breakfast had a 27 percent increased risk of coronary heart disease, possibly because of greater fluctuations in their blood sugar and higher levels of blood triglycerides.

Kick the Can

Energy drinks may be enemy drinks. Research from the University of the Pacific showed that these caffeine-charged beverages can spike BP even in healthy guys. Stick with coffee.

Pour Some Milk

French research found that people who consumed the most low-fat dairy were least likely to have high LDL. The calcium in dairy may help boost fecal fat excretion from your body, which may help lower cholesterol, the scientists say.

Take Your Squats Lower

While any strength training raises your HDL (good) cholesterol, squats will supersize it, since they work your biggest muscles. But do full squats; they activate more small-muscle fibers than half or quarter squats, says Santora.

Rock the Karaoke Bar. . .

. . .and be the Ed Sheeran to her Taylor Swift. Researchers in Sweden found that people who sing together have better heart-rate variability, or the interval of time between beats. And the more variable your heart rate, the better your odds of surviving a heart attack.

Follow the Spice Route

Cinnamon may look like dirt, but it acts like a drug. Two teaspoons of it, consumed with food, can tamp down postmeal blood sugar surges, according to a study published in the Journal of the Academy of Nutrition and Dietetics.

Shack Up

Scientists in Finland say a single guy has up to a 168 percent higher risk of dying of a heart attack than a married man who lives with his mate. Alone? Join a Meetup group; socializing can cut heart-harming stress, Theodore says.

Shun Salad Dressing

Every glug can add about 2 teaspoons of sugar to your salad, triggering spikes in blood sugar and LDL cholesterol, says Janet Bond Brill, author of Blood Pressure Down. Dress greens with olive oil, vinegar, and lemon juice.

Cook Up Some Kale

In a study from Harvard, men who averaged about 1 1/2 servings of leafy greens a day were 12 percent less likely to develop heart trouble than those who ate just one serving a week.

Grin at the Reaper

A sunny outlook may cut your coronary artery disease risk by up to half, say Johns Hopkins researchers, possibly because positivity helps fend off stress and inflammation. For more on this, see "The Price of Pessimism" in this issue.

Color Yourself Healthy

If it's orange, eat it. (Except Cheetos.) A Finnish study found that men with the lowest blood levels of beta-carotene were about three times as likely to develop congestive heart failure as those who had the highest levels.

Go. Nowhere Fast

Hop on a stationary bike. Warm up for five minutes, and then alternate 15 to 30 seconds of fast pedaling with equal amounts of slow recovery. Do this for 10 minutes, rest four minutes, and repeat. This routine can help improve your lipid ratio, a Canadian study found.
