To help thin your blood and prevent heart attacks and strokes many people take a baby aspirin a day. Research has found that a baby aspirin a day does not help first time heart attack. One reason the blood is thickening is due to the buildup of cellular waste. Improve the lymphatic system to help reduce the buildup of cellular waste and inflammation to help thin your blood naturally. As we age many things contribute to thickening our blood which can cause a heart attack; dehydration, inactivity, taking multiple medications, chronic stress, or an acidic pH. You can help reduce your risk of having a first time heart attack by eating a healthier diet, taking a few basic supplements and manually activating your lymphatic system.
