Your boogers smelling like pennies, a metallic scent, often points to a sinus infection, where trapped bacteria and infected mucus create foul odors, or even trace amounts of blood from irritation, but it can also be phantom smells (phantosmia) from inflammation, dental issues, medications, or rarely serious conditions, so if it persists or you have other symptoms, see a doctor.
Experiencing a metallic smell, which is often described as blood-like or similar to iron, can have clear causes. Nasal issues, such as sinus infections or nasal polyps, directly affect the sense of smell and may distort it into sensing metallic odors.
One of the most common causes of strange smells in the nose, including ammonia or metallic odors, is a sinus infection. When the sinuses become inflamed and filled with mucus, bacteria can start to grow, producing unpleasant odors. This kind of smell may be described as metallic, sour, or chemical-like.
Your body naturally contains trace amounts of metals like iron, copper, and zinc. When these metals mix with sweat, they can produce a metallic odor. Hormonal changes, certain medications, or even your diet can affect the levels of these metals, leading to a stronger smell.
Those times when you can smell a very specific odor are known as olfactory hallucinations. These are actually a common aura symptom for patients that have seizures of frontal lobe focus, though these types of seizures have the potential to spread to nearby structures in your brain.
If you're constantly smelling something nobody around you seems to be able to smell, you may have a condition called phantosmia. It's a term used to describe olfactory hallucinations -- that means the organs related to your sense of smell are sensing odors that aren't really there.
Phantosmia is when a person smells something that is not actually there. The smells vary between individuals but are usually unpleasant, such as burnt toast, metallic, or chemical smells. Possible causes range from nasal polyps to a stroke.
Your vaginal discharge may smell slightly metallic — like copper pennies — when you're menstruating. This is because period blood contains iron. A vagina that smells like ammonia may be a sign that there's urine residue on your genitals (vulva) or that you're dehydrated.
Nonenal® (also known as 2-Nonenal) is a naturally occurring compound responsible for the distinct odor associated with aging. It typically appears after age 40, becoming more noticeable in both men and women.
Diabetes can cause sweat to smell sweet, fruity, or like nail polish remover due to high ketone levels from uncontrolled blood sugar (diabetic ketoacidosis or DKA), a serious complication requiring immediate medical attention, often accompanied by excessive thirst, urination, weakness, nausea, or confusion. In some cases, uncontrolled diabetes might also lead to sweat smelling like ammonia, especially with kidney issues, or cause increased sweating.
The most common culprit is sinus infections. When mucus gets trapped and infected, the bacteria produce foul odors. But infections aren't the only reason.
“A metallic or iron-like smell on the breath could be related to certain medical conditions, such as respiratory tract infections, bronchiectasis, or problems with the liver or kidneys.
Runny nose. Sinus pressure. Sinus headache. Smelling foul odors (like burning or rotting) that no one else can smell.
Phantosmia. This is a condition in which people smell certain odours that aren't there. Often these odours are burning, metallic, chemical or rotten. Phantosmia is associated with colds/flus, sinus infections, migraines, epilepsy and stroke.
Sinus infection odor treatment at home
At-home treatment options could include taking medications to help reduce inflammation, as well as using a nasal rinse (saline) to clear out the sinuses. Over-the-counter decongestants and pain relievers may also help to reduce sinus infection odor.
Seek medical attention if the metallic smell persists for more than a few days, is accompanied by other symptoms like headaches or vision changes, or if you experience severe sinus pain or unexplained nosebleeds.
Kids start to have body odor around the time puberty starts and hormones change. Usually, this happens when females are 8–13 years old, and males are 9–14. But it can also be normal to start puberty earlier or later. Bathing every day, especially after a lot of sweating or in hot weather, can help with body odor.
Salty and sweet flavors tend to weaken first. Later, it may be more difficult to taste things that are bitter or sour. Age can also lessen the sense of smell which is strongest when people are between 30 and 60 years old. Some people eventually lose their sense of smell entirely.
Nonenal production usually starts around the age of 40 and can be exasperated by menopause or other fluctuations in hormones. The frustrating thing about Nonenal is that the smell isn't easily removed, especially from fabrics like shirt collars, sheets, and towels.
The Science Behind Scent Transfer
Studies show that microbiota transmission from one partner to another through vaginal sex can persist for several days, suggesting that sexual activities not only change the genital microbiota but could last for several days, allowing putative pathogens to colonize and/or overgrow.
Overall, Experiments 1–3 and a subsequent mini meta-analysis found that men evaluated the scent of sexually aroused women as relatively more attractive. Experiment 2 showed that these sexual chemosignals increased men's self-reported sexual arousal.
A fishy smell from your vagina can be caused by several factors such as sweating, a vaginal infection, your diet or poor hygiene. While some of these causes can be resolved at home, others may need medical treatment.
A metallic vaginal odour is usually caused by blood. This is because blood contains iron, which can smell metallic. During your period, if you smell a metallic smell, this is often normal and nothing to worry about.
Conditions like kidney disease, diabetes or hyperhidrosis can affect how your body processes waste, leading to an intense ammonia smell. It's essential to tune into your body's signals and consult with a healthcare professional if you suspect your sweat's scent is more than just a dietary or exercise-related quirk.
