How do veins grow

Along with more visible veins , the surrounding skin looks thin, which enhances the visual appeal. This is partially due to low levels of subcutaneous fat, which helps achieve defined veins and muscles. They can naturally occur or be the result of unhealthy patterns. Continue reading to learn more about what causes bulging veins as well as what you can do to increase their size and visibility. Your arms may appear veiny both when exercising and standing still.

Protruding veins in your muscles can be the result of a low body fat percentage and high muscle mass. Here are a few reasons why your veins may be more noticeable. This causes your veins to dilate, enhancing vein definition, especially during high-intensity activities. Veiny arms may be a sign that your body is stressed from your fitness or daily routine. Increased stress levels can cause vascularity due to higher levels of the stress hormone cortisol. Another hormone called aldosterone can cause water and sodium retention along with increased blood pressure.

This can lead to vein swelling. Others have naturally larger veins that are more even more apparent if they exercise often. Veins may be more visible in older people, since they have enlarged veins due to weakened valves along with thinner skin with less elasticity. If you want to achieve veiny arms, there are several things you can do to create more definition.

High-intensity weightlifting causes your muscles to enlarge. In turn, that causes your veins to move toward the surface of your skin and pop out more. To build muscle, do strength-building workouts with a high number of reps, heavy weights, and short rest breaks between sets.

Focus on exercises that strengthen the biceps, triceps, and forearm muscles. To increase vascularity, include plenty of movements that require you to lift the weight over or above your head.

Your veins will be more prominent if you have less body fat under your skin covering your muscles. Reduce body fat by upping your cardio and lowering your caloric intake to lose excess weight. A lower body fat percentage will allow you to lose the subcutaneous fat just below your skin, allowing your veins to be more visible.

The circulatory system helps maintain body temperature. Blood vessels expand to release heat, allowing you to cool down, and narrow or constrict to conserve heat, according to the National Library of Medicine. In extreme cases, such as when your feet are exposed to very cold or wet conditions for prolonged periods of time — a condition called trench foot — the constriction of blood vessels can shut down circulation, causing skin tissue to die, according to the U.

Centers for Disease Control and Prevention. Another consequence of extreme exposure is frostbite, which can happen after just a few minutes in freezing conditions. Blame that ice cream headache on your blood vessels.

Anyone who likes popsicles or ice water may be familiar with the uncomfortable sensation known as brain freeze. When something cold touches the warm roof of your mouth, local blood vessels constrict to minimize heat loss, then relax to restore blood flow. This response triggers a burst of pain that lasts for a few minutes, or until the body adapts to the sudden change in temperature, the National Institute of Neurological Disorders and Stroke explains.

The agency notes that ice cream headaches are more common among people who have migraines. Your blood vessels might get a boost from chocolate. Eating moderate amounts of chocolate could offer some benefits, including keeping your heart and blood vessels healthy and helping to lower heart disease and stroke risk , according to a June study published in Heart. How does this guilty pleasure benefit your blood vessels? Chocolate, particularly dark chocolate , contains micronutrients called flavonoids that are believed to have strong antioxidant properties, the American Institute for Cancer Research points out.

Obesity takes a toll on the blood vessels. It's estimated that every pound of fat requires about one extra mile of blood vessels, according to the Obesity Action Coalition — and that means more work for the heart. Zhao explains. For someone who weighs pounds, a one-pound gain isn't going to cross the threshold and put a lot of strain on the heart and blood vessels.

But for someone who is already pounds, it can put a burden on the heart and increase the risk for blockages inside blood vessels, he cautions. Blood vessel damage can start early. But wait a second — why don't you have them?

And why do they look different from the veins on the inside of your wrist or elbow? That's because those grown-up veins are varicose say: VAIR-uh-kose veins. What is a varicose vein, anyway? It's a vein that has become stretched and swollen with blood. To understand how that happens, let's learn a bit about what veins do. You have veins and arteries running through your whole body.

They are tiny tubes that carry blood to and from every part of your body, from your nose down to your toes. The flow of blood starts with the pumping action of your heart. When your heart beats, it pumps your blood and moves it through all those little tubes. The arteries carry the blood from your heart out to your body, and the veins carry the blood from your body back to your heart. The blood going out to your body in the arteries is full of oxygen, which makes the blood bright red.

But the blood coming back from your body in the veins is darker because your body parts have used up the oxygen in the blood. That's why veins look purple or blue. It's a lot of work to move all that blood.

To do their job, veins are full of valves that help keep the blood flowing in the right direction.
