Cortisol News and Research

RSS

Cortisol is a hormone made by the adrenal cortex (the outer layer of the adrenal gland). It helps the body use glucose (a sugar), protein, and fats. Cortisol made in the laboratory is called hydrocortisone. It is used to treat many conditions, including inflammation, allergies, and some cancers. Cortisol is a type of glucocorticoid hormone.

Aircraft noise pollution harms arteries, but heart drugs show promise in animal model research

Disrupting the circadian rhythm of glioblastoma slows tumor growth, study says

Virtually every cell in the human body has an internal clock. These clocks take their cues from a central clock in the brain. In a normal, biological process called synchrony, the central clock coordinates daily rhythms around the body, so that every cell and tissue recognizes the same external time of day.
