The circulatory system is a vital part of the body as it works to pump blood from the heart to the lungs to get oxygen.

The US’s Cleveland Clinic added that bodily arrangement – also known as the cardiovascular system – continues with its functions as the heart then sends oxygenated blood through arteries to the rest of the body.

“The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues,” the renowned medical organisation added.

Healthcare provider Affinity Health added that good circulation was crucial for several reasons.

Affinity Health CEO Murray Hewlett explained that this included:

Cell function

Efficient circulation ensures all cells have enough oxygen and nutrients to operate correctly.

Heart health

Temperature regulation

Circulation helps regulate body temperature by distributing heat evenly throughout the body.

Adequate blood flow to injured areas promotes faster healing and tissue repair, Hewlett noted.

Detoxification

Muscle function

Hewlett explained that muscles require a steady blood supply to function correctly, which makes circulation essential for physical performance.

Signs of poor circulation

Hewlett believes that recognising the signs of poor circulation is essential for early intervention and preventing potential complications.

He said that common symptoms include:

Persistent cold hands and feet can indicate restricted blood flow to these areas.

Numbness and tingling

Swelling

Swollen ankles and legs may result from poor circulation, as blood and fluid accumulate in the lower extremities.

Reduced oxygen supply to cells can lead to unexplained fatigue and weakness.

Slow healing

Skin changes

Skin discolouration, such as pale or bluish skin, may also be a sign of poor body circulation.

Hewlett noted that another sign of poor circulation are enlarged and visible veins, particularly in the legs.

The role of diet in improving circulation

Berries

Strawberries, cherries, blackberries, mulberries, blueberries, and raspberries are strong antioxidants, particularly flavonoids, which can enhance circulation by lowering inflammation and oxidative stress in blood vessels.

Fatty fish

Omega-3 fatty acid-rich fish, such as salmon, mackerel, and sardines, can decrease blood pressure and minimise the risk of blood clots.

Citrus fruits

Citrus fruits, such as oranges, naartjies, limes, lemons, and grapefruits, are abundant in vitamin C, which helps blood vessels work correctly.

Leafy greens

“They are also rich in vitamins and minerals that support overall cardiovascular health.”

Garlic

“It contains allicin, a compound that can help relax blood vessels and reduce blood pressure, leading to improved circulation and a reduced risk of heart disease,” he said.

Nuts

Hewlett added that the unsaturated fats in nuts can also help reduce harmful cholesterol levels and improve blood vessel function.

Dark chocolate

Beets

Beets contain a high concentration of nitrates, which the body converts to nitric oxide.

Turmeric

Affinity Health said that turmeric contains curcumin, a potent anti-inflammatory ingredient that can help decrease inflammation and enhance blood vessel function.

“Ginger has been used for centuries for its medicinal properties, including its ability to improve circulation,” Hewlett said.

He added that it can help reduce blood pressure, relax blood vessels and reduce inflammation.

Watermelon is high in citrulline, which Hewlett believes can increase nitric oxide synthesis, which improves blood flow and circulation.
