Need an emotional lift? Or need to blow off some steam after a stressful day? A gym session or brisk walk can help. Physical activity stimulates various brain chemicals that may leave you feeling happier, more relaxed and less anxious.

Worried about heart disease? Hoping to prevent high blood pressure? Being active boosts high-density lipoprotein (HDL) cholesterol, the “good” cholesterol, and decreases unhealthy triglycerides. This one-two punch keeps your blood flowing smoothly, which decreases your risk of cardiovascular diseases.

Regular exercise helps prevent or manage many health problems and concerns, including:

• Stroke
• Metabolic syndrome
• High blood pressure
• Type 2 diabetes
• Depression
• Anxiety
• Many types of cancer
• Arthritis
• Falls

It can also help improve cognitive function and lower the risk of death from all causes.

Winded by grocery shopping or household chores? Regular physical activity can improve your muscle strength and boost your endurance.

Exercise delivers oxygen and nutrients to your tissues and helps your cardiovascular system work more efficiently. And when your heart and lung health improve, you have more energy to tackle daily chores.

Struggling to snooze? Regular physical activity can help you fall asleep faster, get better sleep and deepen your sleep. Just don’t exercise too close to bedtime, or you may be too energized to go to sleep.

Do you feel too tired or too out of shape to enjoy physical intimacy? Regular physical activity can improve energy levels and increase your confidence, which may boost your sex life.

Exercise and physical activity can be enjoyable. They give you a chance to unwind, enjoy the outdoors or simply engage in activities that make you happy. Physical activity can also help you connect with family or friends in a fun social setting.

So take a dance class, hit the hiking trails or join a soccer team. Find a physical activity you enjoy, and just do it. Bored? Try something new, or do something with friends or family.
