Physical activity plays a significant role in influencing cholesterol levels in the body. Regular exercise can help raise high-density lipoprotein (HDL), often termed the "good" cholesterol, while reducing low-density lipoprotein (LDL) and triglycerides. This balance is crucial for heart health and overall metabolic function. Engaging in aerobic activities like running, cycling, or swimming can promote cardiovascular health and contribute to better cholesterol management, reducing the risk of heart-related diseases.
