Brazilian researchers conducted research and found that cholesterol levels often increase with winter's arrival and drop again as warmer weather returns.

Experts say it's a complex picture and these changes might affect heart attack and stroke risk, but they add there are many other factors to consider.

There are several possible reasons cholesterol varies by season, including changes in diet, exercise and exposure to the sun.

This research is being discussed at the American College of Cardiology's annual scientific session.
