brain, fisher says she wouldn’t be surprised if prolonged bouts had a stress-like effect on your man’s body and mind
testosterone is a caustic substance, she says, and it could eventually stoke the release of anxiety hormones like cortisol, which has been linked to weight gain, depression, and other unhealthy drawbacks
  testosterone and cortisol may also be suppressing the release of the sleep-regulation hormone serotonin, research from the university of pisa in italy shows
as a result, your man not be getting solid sleep at night, which can contribute to emotional chaos
persistently high levels of these hormones may crank up his immune system, elevating his inflammation levels, fisher says
that could make him more likely to get sick, studies suggest
on top of all that, some recent research from israel has linked oxytocin to negative emotions like hate
oxytocin is often called “the love hormone” because it spikes during new bonding phases between lovers
but it may throttle up emotional responses of all types—positive or negative—which may help explain an increasingly bitter attitude toward you, the study authors say

jealousy evokes strong psychological responses, but little is known about physiological effects
this study investigated whether actively thinking about a jealousy-provoking situation would result in a testosterone (t) response, and what factors might mediate this effect
we examined t responses to imagining one’s partner engaging in one of three activities: a neutral conversation with a co-worker, a flirtatious conversation with an attractive person, or a passionate kiss with an attractive person
women in the flirting condition experienced a significantly larger increase in t relative to those in the neutral condition; the kissing condition was intermediate
in men, there were no significant effects of jealousy condition on t
these findings are consistent with the steroid/peptide theory of social bonds, such that the flirting condition elicited a ‘competitive’ t response, and the kissing condition elicited responses consistent with defeat
romantic jealousy is an emotion that arises when a person perceives that a valued relationship is under threat of being lost to another person (holtzworth-munroe et al
1997 ; puente and cohen 2003 ), and such threats may be real or imagined (rilling et al
although jealousy can be experienced as a very serious and upsetting emotion (pines and friedman 1998 ; sheets et al
1997 ), it is commonly understood that jealous feelings can range from normal to pathological, and that those feelings can be manifested in ‘good’ or ‘bad’ ways (conley et al
given that jealousy encompasses a wide range of experiences, there is reason to suspect that not all types of jealousy are predicated upon the same psychological, affective, and physiological processes
determining how these processes may be differentially evoked by different kinds of jealousy could be key to understanding jealousy and its functions in more detail
an important distinction separates sexual jealousy from emotional jealousy (guerrero et al
sexual jealousy involves a threat to exclusive sexual access to a partner whereas emotional jealousy involves a threat to exclusive emotional access to a partner
for the purposes of this study, however, we examine relationships that are both emotional and sexual and thus jealousy that can contain both types; one of many important future questions would be to experimentally test each one separately
testosterone (t) is a steroid hormone that has been associated with sexuality and competition (hamilton et al
2009 ; van anders 2013 ; wingfield et al
although t is positively linked with many aspects of sexual contexts (goldey and van anders 2011 ; van anders 2013 ), associations are more nuanced than largely assumed, with pleasure-focused sexuality especially salient for increasing t in women (van anders and goldey 2010 ; van anders et al
in addition to some sexual contexts, competitive situations—which are defined as those that involve the acquisition or defense of resources (e
, food, territory, or erotic opportunities; van anders et al
2011 )—have also been shown to increase t (carre and mccormick 2008 ; hirschenhauser and oliveira 2006 ; van anders and watson 2006 )
effects of competition on t have been generally investigated within athletic contexts and/or using only men as participants, but competition is also relevant to romantic relationships for both men and women
these relationships can involve maintaining partners over time despite the presence of rivals (vanderlaan and vasey 2008 )
the current study examines whether relationship-based competitions, which could invoke jealousy, are associated with t as well
romantic jealousy might include several socially relevant components, including competition, aggression, and/or intimacy
given t’s important role in social bonding and aggression processes, there is reason to believe that changes in t may be an important pathway through which individuals generate behavioral responses to social stimuli
the steroid-peptide theory of social bonds (s/p theory) identifies two types of aggression (antagonistic and protective) and two types of intimacy (erotic and nurturant) that have different effects on t and peptides (van anders et al
given the multifaceted nature of jealousy, it may evoke some physiological responses relevant to aggression and competition, and other responses consistent with intimacy and bonding
the s/p theory is useful for theorizing how jealousy might affect t: e
, is it an aggressive feeling? a competitive one? a hurt one? a loss of intimacy, or a feeling of increased closeness to a partner whose value is made salient by attention from a rival?
hormonal correlates of jealousy are not widely studied, but the involvement of t in pair bonding suggests that it may be implicated in romantic jealousy as well
furthermore, experiencing jealousy may
