Core T is All: The Male Sexy Hormone
A recent study from the University of Abertay has come out today which challenges testosterone as the primary hormone responsible for male attractiveness; the main culprit is portrayed as cortisol:
Women preferred cues to low cortisol in general and in the fertile phase of the cycle, and there was an interaction between T and cortisol in general and in the non-fertile phase. Results were consistent with the SL-ICHH but not the original immunocompetence handicap model: females expressed preferences for cues to cortisol but not for cues to T, except in interaction with the stress hormone.
Cortisol can be simplified as a stress hormone. The more stressed you are, the more cortisol is floating around your system. Long-term elevated cortisol is hypothesised to play a detrimental effect on health. This is consistent with why the only personality where there is any evidence that there is long-term detrimental health effects is type A.
A brief google search confirms that simple strategies for relaxation such as meditation (or ahem, commonsense: removing a stressor if there is one) helps keep the stress down. I even saw someone say carbohydrates can put your cortisol up (via insulin release, which stimulates cortisol release).
However, the study does have a small sample size. It examined reactions to face only, and not in a holistic manner. I wonder if it’s reproducible.
What do you say girls: is sexual attractiveness something you associate more with someone who’s taking it easy?
