What stresses you out the most? If you're an American man - odds are, it's money.

Two out of three American men reported they are stressed out, with financial situation being the top contributing factor, according to a collaborative survey by Aviva USA and the Mayo Clinic.

Thirty-four percent of men who took the survey said that finances stress them out the most, followed by family and/or relationships, job stability and fast-paced lifestyle, with only 8 percent reporting that they stress about their health.  

Health may be the factor which we have the most control over, yet in this study 25 percent of men did not exercise regularly and 45 percent reported that they experienced an increase in weight over the last decade.  Predictably, this study also revealed a strong correlation between high levels of stress and dramatic weight gain.

It is well-established that stress can negatively affect the immune and cardiovascular systems.  However, more research is needed to understand the relationship between stress and increased susceptibility to disease.
