Your cholesterol goes up over 5 mg/dl in winter and down that much in summer, according to an AMA cholesterol study. You might just get an extra prescription medicine you don’t need if you have a high LDL in winter.
Other blood tests rise when it turns cold: platelet counts, red blood cell counts and blood viscosity, and fibrinogen. Fibrinogen is a blood protein that goes up with inflammation, as does C-Reactive Protein. Fibrinogen is 23% higher in the colder months than in summer. C-Reactive Protein (CRP) should be measured with Cholesterol.
Ask your doctor about measuring your CRP, and flossing to prevent heart attacks—sounds funny, but the inflammation in your gums sets up periodontal disease.
Reduce your risk. Take an unbuffered aspirin daily if it is prescribed to lower heart attack risk. Eat foods that lower your cholesterol and your blood pressure. And keep your hat close by: 40% of your body heat escapes through the top of your head!
