Q. I’m 74 and I don’t seem to be able to endure hot weather the way I used to when I was younger. Is this a common experience as we age?
Yes. I don’t play golf when it’s more than 90 degrees Fahrenheit because it makes me a bit woozy even if I drink a lot of water and seek out the shade. My reaction to heat is caused by blood pressure drugs that I take, my advanced age, and some extra pounds I’m struggling to lose.
Too much heat can make you sick. Heat-related conditions come under the heading, “hyperthermia,” which means “high heat.”
Q. What can you do to prevent heart failure?
There are a number of things that you can do to reduce risk of coronary artery disease and heart failure.
For starters, you should keep the following levels down: body weight, cholesterol, blood pressure, sugar, alcohol and salt. Exercise regularly. If you smoke, quit.
The most common symptoms of heart failure include shortness of breath, fatigue, and swelling, which usually occurs in the ankles, feet and legs. Swelling is caused by fluid buildup in the body and can lead to weight gain, frequent urination and a cough.
Q. What causes rashes?
The most common cause of a rash is contact dermatitis, an inflammation of the skin that comes from direct contact with irritants or allergens. A red, itchy rash from contact dermatitis isn’t contagious, and usually goes away in two to four weeks.
Irritants or allergens include: detergents, soaps, makeup, deodorant, clothing, chemicals, rubber, metals, jewelry, fragrances, plants and medicinal lotions.
There are two types of contact dermatitis.
Irritant contact dermatitis is caused by a substance such as bleach that irritates the skin.

Q. I’ve noticed that food labels list sodium content, but the numbers mean nothing to me. How much is bad?
Diet experts recommend a daily consumption of less than 2,300 milligrams (mg), which is the amount of sodium in a teaspoon of table salt.
If you have high blood pressure, your doctor may advise limiting yourself to 1,500 mg of sodium a day. The average daily intake among United States citizens is 3,400 mg.
Q. I’m going to become a grandmother for the first time and I was wondering how things have changed since I took care of a newborn many years ago.
Probably the most important change is in the approach to Sudden Infant Death Syndrome (SIDS), the abrupt, unexplained death of an infant younger than one-year-old. SIDS is often called crib death because many victims are found in their cribs.
Q. What foods are good for keeping your cholesterol down?
Oatmeal contains soluble fiber that reduces your low-density lipoprotein (LDL), the bad cholesterol that can increase your risk of heart attacks and strokes. This type of fiber is also found in kidney beans, brussels sprouts, apples, pears, barley and prunes.
There are other foods that work against cholesterol. These include soy protein, walnuts and fatty fish.
Soy protein is found in tofu, soy nuts, soy milk and soy burgers.
Q. A friend of mine was diagnosed with Jumping Frenchmen of Maine. Have you ever heard of this?
Not until now. Jumping Frenchmen of Maine is a rare, unexplained disorder that produces an extreme startle reaction to a sudden noise or sight.
Jumping Frenchmen of Maine was first identified during the late 1800s in Maine and the Canadian province of Quebec. It was discovered among an isolated population of French-Canadian lumberjacks. Since the discovery, the extreme startle reaction has been found in other societies in many parts of the world.
Q. I’m going to the doctor and I don’t want to forget to ask him important questions. Any suggestions on how to prepare for this visit?
Whether you’re talking to a family physician, a specialist or pharmacist, you need to know the right questions. My research turned up hundreds of possible questions.
I narrowed the list down to the ones I considered to be the most significant. You can pick out the ones that apply to you.
What is the outlook for my condition?
Could relatives get this?
What changes will I need to make?
Q. Should I take minerals?
It’s important to talk with your doctor before you take mineral pills, especially if you take prescription medicines, have any health problems or are elderly. Taking too much of a mineral can cause problems with some medical tests or interfere with drugs you’re taking.
Minerals are “micronutrients” your body needs in small but steady amounts. Your body can’t make most micronutrients, so you must get them elsewhere.
