Sweating it out over a big date this weekend? If you’re a guy, that could be just the ticket, according to a human biology study released on Friday.
Biologists at the University of Pennsylvania said they found male perspiration had a surprisingly beneficial effect on women’s moods. It helps reduce stress, induces relaxation and even affects the menstrual cycle.
In a study to be published in the journal Biology of Reproduction, researchers collected samples from the underarms of men who refrained from using deodorant for four weeks. The extracts were then blended and applied to the upper lips of 18 women, aged 25 to 45.
The women rated their moods on a fixed scale for a period of six hours. The findings suggested something in the perspiration brightened their moods and helped them feel less tense. Blood analyzes also showed a rise in levels of the reproductive luteinizing hormone that typically surge before ovulation.
