why do we need to keep our body healthy

A healthy body sets the stage for your day-to-day well-being and how well you will age. Maintaining fitness through good nutrition and exercise promotes efficient circulation, digestion and musculoskeletal strength. This allows you to live an active life, and a healthy immune system helps you ward off disease. According to the Centers for Disease Control and Prevention, healthy body benefits extend to mood elevation and greater mental alertness, as well as reduced chronic disease risk. When you keep your metabolism working well, you enjoy greater energy and fewer aches and pains. Adequate vitamins, minerals, dietary fiber, fatty acids and carbohydrates are needed to facilitate all of your body processes. Nightly rest periods allow your body to repair cells and perform other maintenance activities. A sleep or dietary deficiency can deprive your body of these essentials and create fatigue. Getting enough nutrition, on the other hand, leaves you mentally and physically sharp. Regular exercise utilizes your healthy bones, muscles, heart and lungs, preparing them to meet daily demands. When your body reaches a consistent plateau of health, it is more likely to hold up under unusual stress and less likely to give way to infection. A daily fitness program that incorporates aerobic exercise and strengthening of the bones and major muscle groups helps you avoid pulled muscles, joint sprains and bone fractures.

Along with a diet rich in vitamin C, restful sleep supports your immune system. The National Sleep Foundation reports that you are less susceptible to colds and flu if you donвt have a sleep deficit, especially if you are an older adult. Staying fit means less downtime and more time moving and burning calories, which helps you maintain your weight. According to the American Heart Association, 30 minutes of moderate exercise on most days of the week will help to balance your calorie intake from an average healthy diet. Eating low-fat foods that have strong vitamin, mineral and fiber content will help you control your weight as they encourage a healthy cardiovascular system. A diet that is low in sodium and solid fats preserves normal blood pressure and arterial health to reduce your risk for heart disease, the number-one cause of death in America. Staying at a healthy body weight also decreases cardiovascular risk, along with the chances for developing type 2 diabetes and many forms of cancer. Because these illnesses form over time, maintaining your physical health over the course of your life is your best shot at prevention.
A healthy body not only contributes to a more active, productive and fulfilling life, but can also add years to your life.

When your body has a strong immune system to combat health problems, your risk of developing eye problems, arthritis and chronic diseases like cancer, Type 2 diabetes and heart disease is reduced. By following a few guidelines, you can develop habits that contribute to the ongoing health of your body. When you eat right, you not only feel better and have more energy, but you also provide your body with vital nutrients -- protein, carbohydrate, fat, vitamins, minerals and fiber -- that maintain your body's health. A nutrient-rich diet includes whole grains, fish, nuts, eggs, poultry and lean meats, fat-free or low-fat dairy foods such as yogurt and fortified milk, and unsaturated fats like olive oil and avocados. Avoid processed and refined foods, which are typically loaded with saturated fats and sugar. These foods have little nutritional value and can cause your blood glucose levels to rise and then quickly drop, leaving you feeling tired. Like eating a healthy diet, participating in regular exercise is crucial to keeping your body healthy.

Regular physical activity helps control your weight, strengthens your bones and muscles, improves your mood and overall mental health and may add extra years to your life. According to the Centers for Disease Control and Prevention, moderate-intensity exercise, such as brisk walking, is safe for most people. Participate in at least 150 minutes of moderate-intensity aerobic exercise a week. If you are experiencing health issues, check with your doctor before beginning any exercise program. Although the amount of sleep needed varies with each individual, getting adequate, quality sleep plays a vital role not only in your daily performance, but also in keeping your body healthy throughout your life. Sleep is necessary for the healing and repair of your heart and blood vessels. It aids in the balance of your body's hormones and supports your body's growth and development. Your immune system, which defends your body against infections and other harmful substances, relies on adequate sleep to remain strong and function properly. Noticing when your body needs sleep and honoring that need is important to maintaining good health. Aim for seven to eight hours of sleep a day. Stress management in your busy, active life plays an important role in keeping your body healthy.

Although stress can't be avoided, it can be controlled. When stress is repeated, excessive and left untreated, your body can develop physical health problems, such as high blood pressure, weakened immune system, and mental issues like depression and lack of concentration. Strategies like exercise, yoga, meditation or participating in stress-reduction programs are effective ways to manage your stress and help keep your body healthy. Keeping well-hydrated is essential not only to your body's health, but to its survival. Water is an essential nutrient that makes up between 60 and 70 percent of your body. Every cell in your body needs water to function properly. Water maintains body temperature, moves nutrients and waste materials through your body, helps normalize blood pressure and lubricates and cushions body joints and organs. You must replace the water lost through body functions like perspiration and breathing every day to avoid dehydration. Keep a bottle of water handy during the day to drink from. A good rule of thumb for estimating adequate daily water intake is to drink, in ounces, half your total body weight. For example, if you weigh 140 pounds, drink 70 ounces daily.
