Impact of Depression on Thermoregulation

Description

Four groups will be recruited to examine the impact of major depressive disorder and pharmaceutical treatments on thermoregulatory heat loss mechanisms. Adults without MDD, adults with MDD, adults with MDD currently prescribed and taking selective serotonin reuptake inhibitors as treatment, and adults with MDD currently prescribed and taking serotonin norepinephrine reuptake inhibitors as treatment will be recruited to completed a passive heat stress experiment. All subjects will sign an informed consent form and undergo a medical screening prior to participation. Each subject will complete 1 passive heat stress experiment in which body temperature will be using a water perfused suit. During passive heating, body temperature, skin blood flow, and local and whole-body sweat rates will be continuously measured and recorded to compare heat stress responses between groups.
