What to know about Why humans care so much about body odour, and what it really tells us

The article explores the biological and psychological role of smell in humans, contrasting it with animal pheromone systems. It discusses the limitations of human pheromone research while highlighting the potential for scent to communicate emotional states, detect illness, and serve as a future medical diagnostic tool.

What happened

Humans spend a great deal of time trying to smell good.

Why it matters

We wash, deodorise and perfume our bodies daily, suggesting body odour must matter.

Common ground

Yet scientifically, the picture is far less straightforward.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
