Earth's exosphere extends at least 60,000 miles up from the planet’s surface to the edge of interplanetary space. And coincidentally, you have around 60,000 miles of blood vessels in your body.

Those vessels provide pathways for blood carrying oxygen, nutrients, hormones, immune system cells, and platelets (for clotting), and deliver these necessities to your cells and organs while helping transport waste and toxins out of the body. It’s a big job.

But sometimes your circulation becomes obstructed or slowed because of heart disease or blocked arteries. In those cases you may have chronically cold feet or fingers, shortness of breath or fatigue, and even sexual dysfunction.

To ease poor circulation or prevent it from happening, the Cleveland Clinic suggests you:

• Try low-impact exercise such as walking or pool exercise classes.

• Skip red meat and full-fat dairy to reduce or prevent atherosclerosis, which can lead to peripheral artery disease.

• Maintain a healthy blood pressure, and if recommended reduce your salt intake.

• Elevate your legs to about hip level whenever possible.

• Wear compression socks.

• Don't smoke.

In addition, you want to eat a plant-based diet with no simple sugars or syrups, get 150 to 300 minutes of physical activity a week, stay hydrated, and try dry brushing before showering (never on moles or irritated skin). That increases blood circulation.

Some foods and supplements also promote healthy blood flow. These include vasodilating cayenne pepper and pomegranates, and garlic, which contains allicin. Studies show that it relaxes blood vessels.

Other foods to add to your diet to combat restricted blood flow include cooked tomatoes, beets, onions, and berries.
