The yoga routine "ten churnings" can be done on its own to help you get moving in the morning or to counteract stiffness after sitting for too long. In about six minutes, the routine can loosen up your joints and serve as a warm-up to a longer exercise session. To learn additional intermediate yoga exercises, visit: www.health.harvard.edu/iy

Losing weight sometimes takes experimentation. If you give a diet your best shot and it doesn't work long term, maybe it wasn't the right one for you, your metabolism, or your situation. Genes, family, your environment — even your friends — influence how, why, what, and how much you eat, so don't get too discouraged or beat yourself up because a diet that "worked for everybody" didn't pay off for you. Try another, keeping in mind that almost any diet will help you shed pounds — at least for a short time.

Here's a look at three common diet approaches.

Regular physical activity promotes general good health, reduces the risk of developing many diseases, and helps you live a longer and healthier life. For many of us, "exercise" means walking, jogging, treadmill work, or other activities that get the heart pumping.

But often overlooked is the value of strength-building exercises. Once you reach your 50s and beyond, strength (or resistance) training is critical to preserving the ability to perform the most ordinary activities of daily living — and to maintaining an active and independent lifestyle.

Stress eating can ruin your weight loss goals – the key is to find ways to relieve stress without overeating

There is much truth behind the phrase "stress eating." Stress, the hormones it unleashes, and the effects of high-fat, sugary "comfort foods" push people toward overeating. Researchers have linked weight gain to stress, and according to an American Psychological Association survey, about one-fourth of Americans rate their stress level as 8 or more on a 10-point scale.

In the short term, stress can shut down appetite. The nervous system sends messages to the adrenal glands atop the kidneys to pump out the hormone epinephrine (also known as adrenaline). Epinephrine helps trigger the body's fight-or-flight response, a revved-up physiological state that temporarily puts eating on hold.

Reduce indoor allergens that can trigger respiratory problems and other issues.

It may feel cozy being sealed in tight against the cold in your home during the chillier months of the year, but for people who are sensitive to indoor allergens or have respiratory problems, winter can exacerbate problems. Stale indoor air and heating systems can increase the amount of allergy-inducing dust mites, pet dander, and mold spores circulating through your house. In late winter and early spring, it may still be too chilly to throw open the windows to pull out the musty air, so while you await the warmer weather it's important to be aware of some of the allergy and respiratory triggers that may be lurking in your surroundings.

"Most of the things that cause problems are odorless," says Dr. Nicholas BuSaba, associate professor of otolaryng­ology at Harvard ­Medical School. "So, in many cases there's nothing to alert you to the problem." That is, there's nothing other than the symptoms these allergens can trigger — such as respiratory problems (including asthma flare-ups), fatigue and sleepiness, or even digestive issues.

They're great as a substitute for a dumbbell, but a risky choice for some exercises.

When you want to add strength training to your routine, wearable weights seem like a handy shortcut. Just slip them on and do your regular workout. But it's not that simple. "They're great for specific exercises, but they have some risks," says Terry Downey, a physical therapist at Harvard-affiliated Spaulding Rehabilitation Network.

Ankle weights

You may see people walking around with weights around their ankles. The weights are typically built into a wide neoprene strap that wraps around the ankle and attaches with Velcro.

Ask the doctors

Q. I'm very allergic to poison ivy. My spouse currently has a bad poison ivy rash that he got while trimming some bushes in our yard. I'm afraid I'm going to get a rash from him. Is it contagious?

A. Good news: poison ivy rashes are not contagious. You will get a rash from poison ivy only if you come into contact with urushiol oil, which is the plant oil in poison ivy that triggers the rash. In addition, a poison ivy rash, even one with open blisters, won't spread to other areas of the body. The rash only occurs on parts of the body that were actually exposed to the plant oil. Poison ivy rashes can appear to spread if urushiol oil is trapped under your fingernails and you scratch an itch. While you can't get a rash from coming from your spouse, you can get it from clothing or other items that have the plant oil on them. For example, the clothes your spouse was wearing that came into contact with the poison ivy plant. Poison ivy oil can cling to garden tools or even pet fur. The oil from poison ivy is known to linger. According to the FDA, it can stick around on surfaces, sometimes for years, until it is washed away using water or rubbing alcohol. So be certain that all surfaces that are potentially contaminated are cleaned thoroughly to reduce your risk.

Make sure your diet meets the recommended mineral targets.

Gold, silver, and platinum get all the attention as the world's most precious metals. But they're more precious for the global economy than for human health. Instead, other metals and minerals (metals are one type of mineral) are more important for our health (see "What essential metals do for us"). Indeed, some of them are so important that we can't live without them. "Each one plays a role in hundreds of body functions. It may take just a very small quantity of a particular mineral, but having too much or too little can upset a delicate balance in the body," says Dr. Bruce Bistrian, chief of clinical nutrition at Beth Israel Deaconess Medical Center.
