Alcohol consumption stimulates hormones that lead to risky behavior during Mardi Gras.
A study carried out by A Cento and C Simmons on The Correlation Between Alcohol Consumption and Risky Behavior During Spring Break confirmed what has often been observed, that men are more likely to engage in risky behavior during times of high alcohol consumption such as Mardi Gras and Spring Break.
Testosterone levels in men are decreased following alcohol intake, and as a result of this, the brain and pituitary gland are instructed to produce more hormones that stimulate increased production of testosterone.
This may explain why males, particularly those in college, act more wildly than their female counterparts while consuming large quantities of alcohol.
Similar research done on females did not show that alcohol had the same effects on female hormones (Mendelson and Mello, 1985).
