Physical activity positively influences cholesterol levels by increasing HDL (high-density lipoprotein) cholesterol, often referred to as "good" cholesterol, while lowering LDL (low-density lipoprotein), or "bad" cholesterol. Regular exercise promotes better lipid metabolism, helping to improve overall cholesterol ratios and support heart health. Activities such as aerobic exercise, strength training, and even moderate daily activities can significantly affect cholesterol levels and contribute to reducing the risk of cardiovascular diseases. This underscores the importance of integrating regular physical activity into a balanced lifestyle for better heart health.
