Medical professionals confirm that significant changes in body odor can be triggered by hormonal fluctuations. This article addresses the question, 'Can hormonal imbalance cause smelly?', and explains how shifting hormone levels affect sweat composition and skin bacteria, leading to a noticeable change in scent.

According to a 2014 study, the human nose can distinguish over one trillion different smells, yet many people experience the phenomenon of being unable to notice their own body odor. So, **why can you smell yourself but others can't** (or sometimes, vice versa)? It's a matter of biological and neurological filtering that helps your brain focus on new threats and opportunities.

While sweat itself is odorless, over 4 million sweat glands on the human body produce secretions that can be broken down by skin bacteria, causing a distinct smell. A sour milk body odor is the result of this bacterial breakdown, often pointing to specific factors like diet, hormonal shifts, or hygiene.

Did you know that every human has a unique odor signature, a personal 'odorprint' influenced by genetics, much like a fingerprint? This complex signature answers the question: **Do I have a unique smell?**, and is constantly shaped by a fascinating interplay of biology and lifestyle.

Only about 2-10% of alcohol is eliminated through breath, sweat, and urine, while the rest is metabolized by the liver.

According to research published in *Psychological Science*, humans can detect sickness in others through their body odor within just a few hours of an immune system response being triggered. Understanding **what does someone smell like when they are sick** involves examining the volatile organic compounds (VOCs) released by the body, which can signal illness through distinctive changes in scent from the skin, breath, and urine.

According to the National Institute on Alcohol Abuse and Alcoholism, the human body processes alcohol at a fairly consistent rate, meaning the odor can linger long after your last sip.
