It's the new year which means a new start of all of us! Let's make 2015 the healthiest year yet! 1. Don't Overeat Try to stop eating when you are feeling only about 80% full. St. Louis University researchers have confirmed that eating less helps you age slower; in a 2008 study they found that limiting calories lowered production of T3, a thyroid hormone that slows metabolism—and speeds up the aging process. 2. Make More Love Having sex two to three times a week can add as many as three years to your life! Regular sex may also lower your blood pressure, improve your sleep, boost your immunity, and protect your heart. 3. Turn off the TV A 2010 study found that people who watched four or more hours a day were 46% more likely to die from any cause than people who watched less than two hours a day. 4. Stay out of the Sun Avoiding too much sun can help prevent skin cancer, wrinkles, fine lines, and saggy skin. 5. Drink in Moderation Too much alcohol could cause life problems from weight gain to relationship problems. But in smaller quantities, alcohol can actually be good for you. A 2010 study in the Journal of the American College of Cardiology linked light drinking (defined as one drink a day for women and two for men) to significant heart benefits. 6. Focus on Fitness Daily exercise may be the closest thing we have to a fountain of youth. A 2008 study found that regular high-intensity exercise (such as running) can add up to four years to your life! Even moderate exercise—a quick, 30-minute walk each day, for example—can lower your risk of heart problems. 7. Don’t Smoke Quitting smoking is perhaps the single most important thing you can do for your health—and your life span. A study published in the American Journal of Public Health found that women who quit smoking by age 35 add roughly six to eight years to their lives. It's never too late to stop!
