Short periods of stress are unlikely to affect cholesterol levels. However, chronic stress can lead to high cholesterol. Studies show psychological factors, including stress, are significant risk factors for dyslipidemia. Chronic stress causes the body to release cortisol and adrenaline, the two “fight or flight” hormones. These hormones trigger increased LDL cholesterol by releasing triglycerides and free fatty acids and may reduce HDL cholesterol levels. Research to better understand the relationship between stress and blood lipid levels is ongoing.
