• Don't sit around too long. Break up your sitting time by walking around at regular intervals. At home, do a chore. At work, visit a colleague.
• Limit exposure to the sun. Between 11 am and 3 pm, it's better to be in the shade. When in the sun, wear sensible clothing and use appropriate sun factor lotion. Never burn.
• Get enough sleep. The amount varies by individual and age, but most people need seven or eight hours a night. It's important to go to bed at a regular time and get up at a regular time. There is some evidence that people who take a short nap during the day lower the risk of heart disease.
• Be happy. Happiness helps healthiness, especially mental health.
