The Effect of Sexual Selection on Mental Health and Happiness in Humans

For my research I will be writing a literature review on the effect of high-risk sexually-motivated behaviors on happiness and mental health in human males. Behaviors such as alcohol consumption, self-deprecating humor and shows of athleticism have historically been found attractive in a male mate and thus have been sexually selected for. These traits, regardless of whether they have a heritable aspect or are learned, lead to increased reproductive fitness for the male. I am interested in examining whether these prevalent behaviors which are known to have negative effects mental health are compensated for by the mental health benefits of spousal and social relationships.  For example, substance-abuse habits formed while trying to impress a potential mate could possibly trigger an depressive episode. On the other hand, having a rich social and romantic life is widely known to increase happiness. Through this work I am trying to gain a greater insight into how biological pressures such as sexual reproduction can create social norms that affect happiness and mental health. I hope to reach a conclusion on whether extreme behaviors performed to increase sexual fitness have a net negative or net positive impact on happiness and potentially mental health issues.
