How Much Exercise Do I Need?

Regular exercise is one of the best things you can do for your health. It has many benefits. It can improve your overall health and fitness and reduce your risk for many chronic diseases. To get the most benefit, here's how much physical activity you should get:

For adults

Get at least 150 to 300 minutes of moderate-intensity or 75 to 150 minutes of vigorous-intensity aerobic physical activity each week. Or you could do a combination of the two:

• Try to spread your physical activity out over several days of the week. That's better than trying to do it all in one or two days.
• Some days you may not have long blocks of time to do physical activity. You can start slowly and break your exercise time into chunks. Even small amounts of exercise can be helpful.
• Aerobic activities include walking fast, jogging, swimming, and biking.
• Moderate intensity means that while you are doing that activity you should be able to say a few words in a row but not sing.
• Vigorous intensity means that while you are doing that activity, you won't be able to say more than a few words without stopping for a breath.

Also, do strengthening activities two or more days per week:

• Strengthening activities include lifting weights, working with exercise bands, and doing sit-ups and pushups.
• Choose activities that work all parts of your body your legs, hips, back, chest, stomach, shoulders, and arms. For each exercise, try repeating the movement 8 to 12 times. As you get stronger, work up to doing 2 or 3 rounds of each exercise for the best results.

If you are an older adult, you may also benefit from a combination of activities that include aerobic exercises, strength or resistance training, and balance training. Balance training such as walking heel-to-toe or standing on one leg may help improve stability and prevent falls. Before you start exercising, check with your health care provider to determine the best type or amount of activity for you based on your fitness level and health.

For preschool-aged children (ages 3-5)

Preschool children should be physically active throughout the day, to help with their growth and development:

• They should get both structured and unstructured active play. Structured play has a goal and is directed by an adult. Examples include playing a sport or a game. Unstructured play is creative free play, such as playing on a playground.
• Encourage active play with a variety of activities.

For children and teens

Get 60 minutes or more of physical activity every day. Most of it should be moderate-intensity aerobic activity:

• Activities should vary and be a good fit for the child's age and physical development
• Moderate-intensity aerobic activities include walking, running, skipping, playing on the playground, playing basketball, and biking

As part of the 60 minutes or more of daily physical activity, try to do each of these at least 3 days a week: vigorous-intensity aerobic activity, muscle-strengthening activity, and bone-strengthening activity:

• Vigorous-intensity aerobic activities include running, jumping jacks, and fast swimming
• Muscle-strengthening activities include playing on playground equipment, playing tug-of-war, and doing pushups and pull-ups
• Bone-strengthening activities include hopping, skipping, jumping jacks, playing volleyball, and working with resistance bands

Older adults, pregnant women, and people with chronic health problems

Older adults, pregnant women, and people who have disabilities or special health needs should check with their provider on how much physical activity they should get and what types of activities they should do.

Exercise tips

People who are trying to lose weight may need to get more physical activity. They also need to adjust their diet, so they are burning more calories than they eat and drink.

If you have been inactive, you may need to start exercising slowly. You can keep adding more gradually. The more you can do, the better. But try not to feel overwhelmed and do what you can. Getting some physical activity is always better than getting none. Even small increases in exercise can benefit your health.

How to Improve Mental Health

What is mental health?

Mental health includes our emotional, psychological, and social well-being. It affects how we think, feel, and act as we cope with life. It also helps determine how we handle stress, relate to others, and make choices. Mental health is important at every stage of life, from childhood and adolescence through adulthood and aging.

Why is mental health important?

Mental health is important because it can help you to:

• Cope with the stresses of life
• Be physically healthy
• Have good relationships
• Make meaningful contributions to your community
• Work productively
• Realize your full potential

How can I improve my mental health?

There are many different things you can do to improve your mental health, including:

• Staying positive. It's important to try to have a positive outlook; some ways to do that include:
  • Finding balance between positive and negative emotions. Staying positive doesn't mean that you never feel negative emotions, such as sadness or anger. You need to feel them so that you can move through difficult situations. They can help you to respond to a problem. But you don't want those emotions to take over. For example, it's not helpful to keep thinking about bad things that happened in the past or worry too much about the future.
  • Trying to hold on to the positive emotions when you have them
  • Taking a break from negative information. Know when to stop watching or reading the news. Use social media to reach out for support and feel connected to others but be careful. Don't fall for rumors, get into arguments, or negatively compare your life to others.
• Practicing gratitude, which means being thankful for the good things in your life. It's helpful to do this every day, either by thinking about what you are grateful for or writing it down in a journal. These can be big things, such as the support you have from loved ones, or little things, such as enjoying a nice meal. It's important to allow yourself a moment to enjoy that you had the positive experience. Practicing gratitude can help you to see your life differently. For example, when you are stressed, you may not notice that there are also moments when you have some positive emotions. Gratitude can help you to recognize them.
• Taking care of your physical health, since your physical and mental health are connected. Some ways to take care of your physical health include:
  • Being physically active. Exercise can reduce feelings of stress and depression and improve your mood.
  • Getting enough sleep. Sleep affects your mood. If you don't get a good sleep, you may become more easily annoyed and angry. Over the long term, a lack of quality sleep can make you more likely to become depressed. So it's important to make sure that you have a regular sleep schedule and get enough quality sleep every night.
  • Healthy eating. Good nutrition will help you feel better physically but could also improve your mood and decrease anxiety and stress. Also, not having enough of certain nutrients may contribute to some mental illnesses. For example, there may be a link between low levels of vitamin B12 and depression. Eating a well-balanced diet can help you to get enough of the nutrients you need.
• Connecting with others. Humans are social creatures, and it's important to have strong, healthy relationships with others. Having good social support may help protect you against the harms of stress. It is also good to have different types of connections. Besides connecting with family and friends, you could find ways to get involved with your community or neighborhood. For example, you could volunteer for a local organization or join a group that is focused on a hobby you enjoy.
• Developing a sense of meaning and purpose in life. This could be through your job, volunteering, learning new skills, or exploring your spirituality.
• Developing coping skills, which are methods you use to deal with stressful situations. They may help you face a problem, take action, be flexible, and not easily give up in solving it.
• Meditation, which is a mind and body practice where you learn to focus your attention and awareness. There are many types, including mindfulness meditation and transcendental meditation. Meditation usually involves:
  • A quiet location with as few distractions as possible
  • A specific, comfortable posture. This could be sitting, lying down, walking, or another position.
  • A focus of attention, such as a specially chosen word or set of words, an object, or your breathing
  • An open attitude, where you try to let distractions come and go naturally without judging them
• Relaxation techniques are practices you do to produce your body's natural relaxation response. This slows down your breathing, lowers your blood pressure, and reduces muscle tension and stress. Types of relaxation techniques include:
  • Progressive relaxation, where you tighten and relax different muscle groups, sometimes while using mental imagery or breathing exercises
  • Guided imagery, where you learn to focus on positive images in your mind, to help you feel more relaxed and focused
  • Biofeedback, where you use electronic devices to learn to control certain body functions, such as breathing, heart rate, and muscle tension
  • Self-hypnosis, where the goal is to get yourself into a relaxed, trance-like state when you hear a certain suggestion or see a specific cue
  • Deep breathing exercises, which involve focusing on taking slow, deep, even breaths

It's also important to recognize when you need to get help. Talk therapy and/or medicines can treat mental disorders. If you don't know where to get treatment, start by contacting your primary care provider.

Kidney Transplantation

A kidney transplant is an operation that places a healthy kidney in your body. The transplanted kidney takes over the work of the two kidneys that failed, so you no longer need dialysis.

During a transplant, the surgeon places the new kidney in your lower abdomen and connects the artery and vein of the new kidney to your artery and vein. Often, the new kidney will start making urine as soon as your blood starts flowing through it. But sometimes it takes a few weeks to start working.

Many transplanted kidneys come from donors who have died. Some come from a living family member. The wait for a new kidney can be long.

If you have a transplant, you must take drugs for the rest of your life, to keep your body from rejecting the new kidney.

Laboratory Tests

Laboratory tests check a sample of your blood, urine, or body tissues. A technician or your doctor analyzes the test samples to see if your results fall within the normal range. The tests use a range because what is normal differs from person to person. Many factors affect test results. These include:

• Your sex, age and race
• What you eat and drink
• Medicines you take
• How well you followed pre-test instructions

Your doctor may also compare your results to results from previous tests. Laboratory tests are often part of a routine checkup to look for changes in your health. They also help doctors diagnose medical conditions, plan or evaluate treatments, and monitor diseases.

Low Blood Pressure

You've probably heard that high blood pressure is a problem. Sometimes blood pressure that is too low can also cause problems.

Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps out blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is the diastolic pressure. Your blood pressure reading uses these two numbers. Usually they're written one above or before the other, such as 120/80. If your blood pressure reading is 90/60 or lower, you have low blood pressure.

Some people have low blood pressure all the time. They have no symptoms and their low readings are normal for them. In other people, blood pressure drops below normal because of a medical condition or certain medicines. Some people may have symptoms of low blood pressure when standing up too quickly. Low blood pressure is a problem only if it causes dizziness, fainting or in extreme cases, shock.
