Taste blood when running
Rhye – taste (official audio)
You’re in the midst of a strenuous exercise routine. Your pulse quickens. Your muscles plead for forgiveness. Sweat pours down your brow. And the taste of blood is unmistakable in your mouth. What’s going on here? Although it can seem strange to others, many athletes understand exactly what I’m talking about. It’s not unusual to experience a rusty, bloody taste in the mouth during vigorous exercise, but it can be perplexing. It’s even more perplexing when the flavor isn’t followed by any obvious blood in your saliva.

Some people report a “bloody” taste in their mouth during or after exercise, while others report a “metallic” flavor. It’s likely that they’re tasting something similar but categorizing it differently. Blood has a metallic taste due to its high iron content, which some people associate with it.

If you’re a runner, cyclist, or other endurance athlete, you’ve probably had a bloody metallic taste in your mouth at some point during your workout. I’m sure you’re still curious as to why this occurs.
A quick lesson in physiology. Your heart rate and blood pressure rise when you exercise, particularly at a high intensity. Since your heart has to pump more oxygen-rich blood to keep your muscles going, these two things happen. To get the oxygen, this blood must also be pumped into the lungs.
When you take large gulps of oxygen during an intense exercise, the oxygen travels down your trachea (windpipe), to the bronchioles, and eventually to the tiniest sacs in your lungs. The alveoli are the lungs’ air sacs.
The alveoli are delicate little things (very small and porous), and a rise in blood pressure caused by vigorous exercise will cause them to burst and leak blood (hemoglobin), which is iron-rich.
Some of the blood from the broken alveoli travels to your mouth through the bronchi. The blood’s iron molecules come into contact with iron-sensitive receptors on the tongue until it enters our mouth.

If I “press it” on the treadmill or during a race for an extended period of time (even as little as 10 minutes), I will most likely experience something difficult to explain, but I will try. It’s essentially a metallic “taste,” but it seems to be coming from my brain and is more of a general sense of metal than a taste. This is what my brain would taste like if it had tastebuds. You may think this is absurd, or you may say, “That’s it!” I suppose your mileage will vary (pun intended).
Unless you have some unexplained medical problems, it’s conceivable that you’re actually exerting yourself beyond your heart’s capacity to keep up. The fact that you mention that this happens when you put too much pressure on yourself. When the heart is at rest, it pumps out as much blood as it takes in. The right side of the heart (atrium to ventricle) receives blood from the body, which is then pumped to the lungs for reoxygenation. The reoxygenated blood then returns to the left side of the heart, where it is sent to the rest of the body (and then that spent blood goes back to the heart via the right, etc.).
I taste blood in my mouth(no skill)
It’s been discussed on runner’s forums for a while, but the cause of the strange taste you get after a hard workout remains a mystery. In his position as physician assistant and director of team medicine at South Sound Sports Medicine Clinic in Auburn, Washington, Ryan Dirks is frequently asked this question.
He says, “There isn’t always a clear answer—truthfully, we don’t always know why it happens.” Additional testing may be needed to determine the source of your symptoms, but there are a few less invasive alternatives.
First and foremost, according to Dirks, his team prefers to rule out problems inside the mouth. “Just like kidney stones, you can get stones in your salivary ducts, which can cause a blockage or an infection,” he says. Physical exercise and deep breathing will increase saliva production, which can result in a nasty, metallic taste from a contaminated duct, he says. For similar purposes, tooth decay may also be to blame.
Inflammation and tiny cracks in the lining of your nose and throat, particularly if you’re breathing in cold, dry air or if you’re at a higher altitude where the air is thinner, may also be to blame. (Fun fact: Because of its iron content, blood tastes like metal.)
