Study suggests sniffing body odor can reduce social anxiety.

A study by researchers from Karolinska Institute in Sweden has found that exposure to human "chemo-signals" in body odour can reduce social anxiety by nearly 40% when combined with mindfulness therapy. The researchers asked 48 women with social anxiety to sniff some of the armpit sweat samples alongside receiving mindfulness therapy. Those who sniffed body odour appeared to do better with the therapy. The study suggests that human body odour can even tell our emotional state- happy or anxious.
