Here are the best ways to stop painful cramps — and prevent them from returning.

A muscle cramp always feels like a surprise. The involuntary contraction strikes without warning, whether it's a charley horse in the middle of night or a back spasm as you reach for an everyday object. But don't let that cramp throw you for a loop. "When it suddenly strikes, don't exercise or tighten the muscle. Just gently stretch it to your tolerance. That helps to relax the muscle and relieve the uncontrolled contraction," says Madhuri Kale, a physical therapist at Harvard-affiliated Brigham and Women's Hospital.

What causes cramps?

Exercising without properly warming up the muscles can lead to cramps. Cramps also occur when a muscle is not able to relax properly (such as from a deficiency of magnesium or potassium in your diet) or when it becomes irritated by a buildup of lactic acid (which can happen if you don't rest your muscle after it has exercised a lot). Dehydration can worsen both of these problems. Kale says older adults often don't drink enough water at night because they want to avoid having to go the bathroom, and they end up dehydrated.

Strengthening your core muscles doesn't have to be overwhelming. You can do these simple exercises anywhere and adapt them as you gain fitness.

The office workout

The following routine is a great way to ease into core work. You can do these four exercises at work, without your colleagues being any the wiser. You can do these exercises at home, too, thanks to simple variations. The front plank, for example, can be done while either leaning on your desk or using the kitchen counter to support your weight.

Antidepressants aren't the only solution for depression. Research shows that exercise works as well as antidepressants for some people, although exercise alone isn't enough for someone with severe depression.

Thinking about exercising is great, but just jumping in is often the best way to blast past mental or emotional barriers. You don’t need a complex workout program; start small and focus on making activity a daily habit. Here are easy ways to add activity to your day.

Ever wonder how much exercise time it takes to start reducing your risk for heart disease and diabetes? It could be as little as 12 minutes, according to a Harvard study published Nov. 17, 2020, in Circulation. Scientists analyzed blood from more than 400 middle-aged men and women before and just after they'd pedaled for 12 minutes on cycling machines, reaching a vigorous rate. In particular, scientists measured levels of almost 600 natural body chemicals (metabolites). Exercise produced significant changes in most metabolites. For example, the level of one metabolite linked to heart disease and diabetes fell by 29%. Another metabolite tied to diabetes risk and liver disease fell by 18%. That suggests, but doesn't prove, that 12 minutes of daily exercise (that includes vigorous activity) might reduce the risk of heart disease and diabetes. What if you're more of a moderate-intensity exerciser? "We don't know yet if moderate-intensity exercise would have a similar effect on metabolites. But study participants started off with very light exercise, and each minute the intensity increased," says Dr. Gregory Lewis, the study's senior author and a cardiologist at Harvard-affiliated Massachusetts General Hospital.

Experts say there's little evidence that low-dose aspirin therapy brings benefits, and there are some risks.

In recent years, there's been a lot of talk about the potential benefits, and risks, of a regular regimen of low-dose aspirin. While much of the discussion has centered on whether taking low-dose aspirin can head off cardiovascular disease, some of the focus has also been on breast cancer. Can regular doses of this over-the-counter pain reliever reduce your risk of this common cancer?

For a while there were hints that the evidence was leaning that way. Back in 2017, this area of research, while still inconclusive, was somewhat promising. For example, a 2017 study published in Breast Cancer Research found that among some 57,000 women, those who reported taking low-dose aspirin (81 mg) at least three times a week had a 16% lower risk of breast cancer over all and a 20% lower risk of a specific type of hormonally driven breast cancer.

Listening to music may offer a range of benefits for cardiovascular health.

Music's capacity to evoke emotion is one reason people love listening to it so much. Whether you want to feel energized and uplifted or calm and relaxed, you can probably conjure a few examples of melodies that put you in your desired frame of mind. As it turns out, those mood-related benefits may extend to your heart.

"The beating of your heart and your fight-or-flight system are regulated by your brain. Once you understand that, it makes sense that listening to music that evokes a certain mood might affect the heart's function," 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.

Strengthening your core using plank exercises can help ease back pain. The plank position is essentially the high part of a push-up. People who can't hold this position can try a modified version by bending their knees and resting them on the ground. Build strength by practicing holding a plank for as long as you can, and then progressively working to hold it for longer each time.

Research we're watching

If you're looking forward to having some extra downtime after retirement, just make sure it doesn't bring more sitting-down time. A study published online Nov. 17, 2020, by the journal Occupational and Environmental Medicine found that on average, women saw a sharp increase in sedentary time — more than an additional 20 minutes each day — after they retired compared with when they were working. This is an unhealthy pattern that can lead to a higher risk for cardiovascular disease.

Researchers identified this trend by looking at data on nearly 700 people (nearly 85% of them women) from a Finnish study. Most of the participants worked in administrative roles or held professional positions before retiring at an average age of 63. To provide objective measurements of activity, the participants wore activity monitors continuously for a full week during their one or two years both before and after retirement. The spike in sedentary time occurred after retirement, and remained at the reduced level for the next two years or more following retirement. Men, by contrast, saw a gradual decline in their activity level over time, but no sudden spike after they left their jobs. So, if you're retiring in the near future, it may be worth keeping an eye on your activity level to make sure you don't slow down after you leave your job.

The soothing and motivational sounds of music have far-reaching health benefits.

A favorite musical tune can stir up positive memories, boost your mood, and create a soothing, relaxing setting. But used in specific ways, music also is a valuable tool for supporting your health.

"Whether you need to relax, increase your energy, improve your thinking, or just get motivated for the day, music can provide extra support when you need it the most," says Marisabelle Diaz-Falcon, a music therapist with Harvard-affiliated Massachusetts General Hospital.
