Feeling dazed and confused in the yogurt aisle? Here's some information to help you make good choices.

Yogurt used to be pretty straightforward. It came in small, simple containers, with a swirl of fruit on the bottom if you were lucky. Not anymore. Today there's Greek yogurt, shakes, and tasty-looking cups with sprinkles and crushed cookies. Yogurt is blended into smoothies and squirted into portable tubes and pouches. Over in the ice cream aisle, there are even more options, with a variety of frozen yogurt products in tubs and handheld popsicles.

This gives you lots of choices but might also leave you wondering which one to pick. At the root of the dilemma is this question: is yogurt a health food or a dessert? The truth is, today's yogurt can be either, depending on the type you choose. This means you've got to do a little detective work to figure it out.

A sauna benefits your heart health, as long as you practice sauna safety

A saunas' dry heat (which can get as high as 185° F) has profound effects on the body. Skin temperature soars to about 104° F within minutes. The average person will pour out a pint of sweat during a short stint in a sauna. The pulse rate jumps by 30% or more, allowing the heart to nearly double the amount of blood it pumps each minute. Most of the extra blood flow is directed to the skin; in fact, the circulation actually shunts blood away from the internal organs. Blood pressure is unpredictable, rising in some people but falling in others.

Saunas appear safe for most people. However, people with uncontrolled high blood pressure and heart disease should check with their doctors before taking a sauna.

While it's not a life-or-death matter, athlete's foot-especially if it's persistent-can be painful and make walking difficult.

The early signs of athlete's foot are patches or fissures (deep breaks or slits), especially between the toes. As the infection progresses, the skin may turn red, become itchy, and appear moist. Small blisters may spread out across the foot, breaking to expose raw fissures that are painful and may swell. The area between the toes is most often affected, but the infection may spread to the soles of the feet or to the toenails, which can become thick and colored white or cloudy yellow. In the most advanced cases, the rash will extend moccasin-style across the sole of your foot, and your feet may ooze pus and develop a foul odor.

It's more important than ever to consider your particular health risks before popping a nonprescription pain reliever.

Have a headache, muscle strain, or maybe arthritis pain? Don't reach for just any over-the-counter (OTC) remedy. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin), naproxen (Aleve), and aspirin are commonly used OTC painkillers. So is acetaminophen (Tylenol). For decades, these drugs were thought to be entirely safe — justifying the ability to purchase them without a doctor's prescription.

But the thinking on OTC painkillers has changed now that we know more about their risks. And it's especially important to navigate these medications with care. Here are guidelines to help you narrow the options.

Ask the doctor

Q. You recommend eating fish twice a week. However, I've read that fish contain toxins and microplastics. Is it really safe to eat fish?

A. Most options in life contain both benefits and risks. Foods are no exception. Eating fish has potential benefits (largely from the omega-3 fats they contain) and risks (from the toxins). Do the benefits exceed the risks? That question has been addressed by research — much of it by colleagues here at Harvard. The answers are different for different people, and for different types of fish.

Asking some simple questions can help you determine what medical research to pay attention to and when to wait for more information.

Every day there's something new in the world of medical research, and sometimes the results conflict. Eggs are good for your heart, or not. First surgery is advised to repair tears to cartilage in the knee, then nonsurgical options are favored. Do this, not that, for better health. For many women, all this information is a little confusing. When should you change your health habits, and when should you wait for more information? How can you tell the difference?

"It can be difficult for the consumer to know what research study is preliminary at best and in need of replication, versus a study that should cause you to change your life," says Dr. Andrew Budson, a lecturer in neurology at Harvard Medical School and chief of cognitive and behavioral neurology at the VA Boston Healthcare System.

Some trends are high-tech, and some go back to basics.

One of the best ways to sustain an exercise regimen is to find an activity that appeals to you. And four new exercise trends may pique your interest. They're not age-specific and most can be tailored to your needs. But they do have pros and cons.

1. Circuit training

When people talk about circuit training in 2020, they're probably not referring to working out on a series of weight machines. Today's circuit consists of a series of exercises, set up at separate "stations" in various parts of a large exercise room. "The exercises focus on agility, balance, or strength, and they alternate between upper- and lower-body movements to avoid excessive fatigue in any one muscle group," says Michael Bento, a personal trainer at Harvard-affiliated Massachusetts General Hospital.

These are the most effective ways to protect yourself.

Here are some alarming statistics about heart attacks:

• Every 40 seconds, someone in the United States has a heart attack.
• Every year, about 805,000 Americans have heart attacks, 75% of which are first-time attacks.
• The average age of a first heart attack among men: 65.

However, the most troubling fact about heart attacks is that many people don't take steps to protect themselves, says Dr. Deepak L. Bhatt, executive director of interventional cardiovascular programs at Harvard-affiliated Brigham and Women's Hospital Heart & Vascular Center. "Reducing your risk of cardiovascular disease is the best way to guard against heart attacks," he says. "There are simple ways to do this, but unfortunately, many people still don't follow them as they should."

Here's a look at five ways you can protect yourself from cardiovascular disease, and thus possible heart attacks, and avoid being another statistic.

Research we're watching

If you have children in your house — even for a few hours at a time — be certain to store your medications safely. A study in the January 27 issue of Pediatrics found that more than half of the time, accidental poisonings with prescription medication occurred because adults had removed the medicine from a child-resistant container before the child discovered it.

CDC researchers examined calls made between February and September 2017 to five poison control centers to determine how these accidents most often occur. Most of the time, the pills that children encountered belonged to a parent, but in more than half of cases involving particularly harmful medication, it belonged to a grandparent. These medications included drugs to treat diabetes or cardiac conditions. Child-resistant packaging can help protect children, but it's often inconvenient for adults. Study authors found that most often when poisonings occurred, it was because adults put the pills into pill organizers that were not child-safe, stored them in small plastic bags, or left them out on a surface that a child was able to reach. In other cases, a child found a pill that was dropped on the floor.
