Hay Fever

Each spring, summer, and fall, trees, weeds, and grasses release tiny pollen grains into the air. Some of the pollen ends up in your nose and throat. This can trigger a type of allergy called hay fever.

Symptoms can include:

• Sneezing, often with a runny or clogged nose
• Coughing and postnasal drip
• Itching eyes, nose and throat
• Red and watery eyes
• Dark circles under the eyes

Your health care provider may diagnose hay fever based on a physical exam and your symptoms. Sometimes skin or blood tests are used. Taking medicines and using nasal sprays can relieve symptoms. You can also rinse out your nose, but be sure to use distilled or sterilized water with saline. Allergy shots can help make you less sensitive to pollen and provide long-term relief.

Head Injuries

Chances are you've bumped your head before. Often, the injury is minor because your skull is hard and it protects your brain. But other head injuries can be more severe, such as a skull fracture, concussion, or traumatic brain injury.

Head injuries can be open or closed. A closed injury does not break through the skull. With an open, or penetrating, injury, an object pierces the skull and enters the brain. Closed injuries are not always less severe than open injuries.

Some common causes of head injuries are falls, motor vehicle accidents, violence, and sports injuries.

It is important to know the warning signs of a moderate or severe head injury. Get help immediately if the injured person has:

• A headache that gets worse or does not go away
• Repeated vomiting or nausea
• Convulsions or seizures
• An inability to wake up
• Dilated (enlarged) pupil in one or both eyes
• Slurred speech
• Weakness or numbness in the arms or legs
• Loss of coordination
• Increased confusion, restlessness, or agitation

Doctors use a neurologic exam and imaging tests to make a diagnosis. Treatment depends on the type of injury and how severe it is.

Health Fraud

Health fraud involves selling drugs, devices, foods, or cosmetics that have not been proven effective. Keep in mind - if it sounds too good to be true, it's probably a scam. At best, these scams don't work. At worst, they're dangerous. They also waste money, and they might keep you from getting the treatment you really need.

Health fraud scams can be found everywhere, promising help for many common health issues, including weight loss, memory loss, sexual performance, and joint pain. They target people with serious conditions like cancer, diabetes, heart disease, HIV/AIDS, arthritis, Alzheimer's, and many more.

To protect yourself, recognize the red flags such as:

• Miracle cure
• Quick fix
• Ancient remedy
• Secret ingredient
• Scientific breakthrough

Before taking an unproven or little known treatment, talk to a doctor or health care professional - especially when taking prescription drugs.

Health Risks of an Inactive Lifestyle

What is an inactive lifestyle?

Being a couch potato. Not exercising. A sedentary or inactive lifestyle. You have probably heard of all of these phrases, and they mean the same thing: a lifestyle with a lot of sitting and lying down, with very little to no exercise.

In the United States and around the world, people are spending more and more time doing sedentary activities. During our leisure time, we are often sitting: while using a computer or other device, watching TV, or playing video games. Many of our jobs have become more sedentary, with long days sitting at a desk. And the way most of us get around involves sitting - in cars, on buses, and on trains.

How does an inactive lifestyle affect your body?

When you have an inactive lifestyle,:

• You burn fewer calories. This makes you more likely to gain weight.
• You may lose muscle strength and endurance, because you are not using your muscles as much
• Your bones may get weaker and lose some mineral content
• Your metabolism may be affected, and your body may have more trouble breaking down fats and sugars
• Your immune system may not work as well
• You may have poorer blood circulation
• Your body may have more inflammation
• You may develop a hormonal imbalance

What are the health risks of an inactive lifestyle?

Having an inactive lifestyle can be one of the causes of many chronic diseases. By not getting regular exercise, you raise your risk of:

• Obesity
• Heart diseases, including coronary artery disease and heart attack
• High blood pressure
• High cholesterol
• Stroke
• Metabolic syndrome
• Type 2 diabetes
• Certain cancers, including colon, breast, and uterine cancers
• Osteoporosis and falls
• Increased feelings of depression and anxiety

Having a sedentary lifestyle can also raise your risk of premature death. And the more sedentary you are, the higher your health risks are.

How can I get started with exercise?

If you have been inactive, you may need to start slowly. You can keep adding more exercise gradually. The more you can do, the better. But try not to feel overwhelmed, and do what you can. Getting some exercise is always better than getting none. Eventually, your goal can be to get the recommended amount of exercise for your age and health.

There are many different ways to get exercise; it is important to find the types that are best for you. You can also try to add activity to your life in smaller ways, such as at home and at work.

How can I be more active around the house?

There are some ways you can be active around your house:

• Housework, gardening, and yard work are all physical work. To increase the intensity, you could try doing them at a more vigorous pace.
• Keep moving while you watch TV. Lift hand weights, do some gentle yoga stretches, or pedal an exercise bike. Instead of using the TV remote, get up and change the channels yourself.
• Work out at home with a workout video (on your TV or on the internet)
• Go for a walk in your neighborhood. It can be more fun if you walk your dog, walk your kids to school, or walk with a friend.
• Stand up when talking on the phone
• Get some exercise equipment for your home. Treadmills and elliptical trainers are great, but not everyone has the money or space for one. Less expensive equipment such as yoga balls, exercise mats, stretch bands, and hand weights can help you get a workout at home too.

How can I be more active at work?

Most of us sit when we are working, often in front of a computer. In fact, less than 20% of Americans have physically active jobs. It can be challenging to fit physical activity into your busy workday, but here are some tips to help you get moving:

• Get up from your chair and move around at least once an hour
• Stand when you are talking on the phone
• Find out whether your company can get you a stand-up or treadmill desk
• Take the stairs instead of the elevator
• Use your break or part of your lunch hour to walk around the building
• Stand up and walk to a colleague's office instead of sending an email
• Have "walking" or standing meetings with co-workers instead of sitting in a conference room

High Blood Pressure

What is blood pressure?

Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps 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 called diastolic pressure.

Your blood pressure reading uses these two numbers. Usually the systolic number comes before or above the diastolic number. For example, 120/80 means a systolic of 120 and a diastolic of 80.

How is high blood pressure diagnosed?

High blood pressure usually has no symptoms. So the only way to find out if you have it is to get regular blood pressure checks from your health care provider. Your provider will use a gauge, a stethoscope or electronic sensor, and a blood pressure cuff. He or she will take two or more readings at separate appointments before making a diagnosis.

Blood Pressure CategorySystolic Blood PressureDiastolic Blood PressureNormalLess than 120andLess than 80High Blood Pressure (no other heart risk factors)140 or higheror90 or higherHigh Blood Pressure (with other heart risk factors, according to some providers)130 or higheror80 or higherDangerously high blood pressure - seek medical care right away180 or higherand120 or higher

For children and teens, the health care provider compares the blood pressure reading to what is normal for other kids who are the same age, height, and sex.

What are the different types of high blood pressure?

There are two main types of high blood pressure: primary and secondary high blood pressure.:

• Primary, or essential, high blood pressure is the most common type of high blood pressure. For most people who get this kind of blood pressure, it develops over time as you get older.
• Secondary high blood pressure is caused by another medical condition or use of certain medicines. It usually gets better after you treat that condition or stop taking the medicines that are causing it.

Why do I need to worry about high blood pressure?

When your blood pressure stays high over time, it causes the heart to pump harder and work overtime, possibly leading to serious health problems such as heart attack, stroke, heart failure, and kidney failure.

What are the treatments for high blood pressure?

Treatments for high blood pressure include heart-healthy lifestyle changes and medicines.

You will work with your provider to come up with a treatment plan. It may include only the lifestyle changes. These changes, such as heart-healthy eating and exercise, can be very effective. But sometimes the changes do not control or lower your high blood pressure. Then you may need to take medicine. There are different types of blood pressure medicines. Some people need to take more than one type.

If your high blood pressure is caused by another medical condition or medicine, treating that condition or stopping the medicine may lower your blood pressure.
