leg cramps or Charley Horse

Leg cramps - also know as night cramps or Charley Horse - are painful spasms that typically occur in the calf muscles. Leg cramps tend to jolt a person awake in the middle of the night, but can also strike in the daytime during physical activities such as running and cycling. Fitness can put strain on your leg muscles. Some leg muscle cramps - which can last anywhere from a few seconds to up to 10 minutes - may also be the result of a sedentary lifestyle.

What Causes Leg Cramps and How Can You Stop Them?


Are leg cramps cramping your style? If so, here are some ways to make that Charlie Horse gallop away.



Leg cramps - also know as night cramps or Charley Horse - are painful spasms that typically occur in the calf muscles. Leg cramps tend to jolt a person awake in the middle of the night, but can also strike in the daytime during physical activities such as running and cycling. Fitness can put strain on your leg muscles. Some leg muscle cramps - which can last anywhere from a few seconds to up to 10 minutes - may also be the result of a sedentary lifestyle.
What Causes Muscle Cramps in the Calves?
"Leg cramps can be caused by many conditions, ranging simply from dehydration to something much more serious such as kidney disease," said physical therapist Matthew Hyland, president of the New York Physical Therapy Association and co-owner of Rye Physical Therapy & Rehabilitation. "Cramps often result from vigorous exercise, trauma to the muscle, or keeping the leg in an awkward position for too long, such as sitting in a crowded theater. Other causes can include medications such as birth control, diuretics (which are often prescribed for people with high blood pressure) and steroids. A lack of potassium or calcium can also be the underlying cause, as well as cold weather."
Acute leg cramps frequently are confused with restless legs syndrome (RLS). But RLS is a different and more serious, chronic condition characterized by discomfort and persistent throbbing and pulling sensations in the legs.
How to Prevent Leg Cramps
There are a number ways you can alleviate nighttime leg cramps. "Once leg cramps set in, the best method to relieve them is movement, either walking around or simply jiggling or shaking your leg," advised Hyland. "In addition, things like pumping your ankles up and down or rubbing the muscles can help as well."
Some people with chronic leg cramps have found relief using cool compresses, which work by numbing pain and reducing soreness. But Hyland said anyone who regularly suffers leg cramps should also work to strengthen their muscles, which will make cramps less frequent.
"Our musculoskeletal system hits its peak at the age of 20, and while it maintains its peak for an additional 20 years, the reality is that it begins to break down at age 40," he said. "This includes muscles becoming less flexible. Once we pass into the fourth decade of life, it is critical we play an active role in stretching and strengthening our bodies to maintain appropriate, maximal health." He added that it may be best to consult a physician if leg cramps last for 5 to 10 minutes or occur multiple times a week.
What to Take for Muscle Cramps
Analgesic balm or a patch, both sold over-the-counter at pharmacies, can provide further relief. OTC pain relief medications that are formulated to treat menstrual cramps, such a Pamprin and Midol, can be an effective treatment for bad leg cramps.
You may also be able to prevent or alleviate muscle cramps in your legs by making simple lifestyle changes. Drinking plenty of water is essential, since cramps are often caused by dehydration. A healthy diet with plenty of fresh fruits and vegetables can also help to decrease the frequency of leg cramps.
Vitamins and Minerals: Potassium and Magnesium for Muscle Cramps
Additionally, certain vitamins and minerals impact muscle function, particularly potassium and magnesium. A significant body of research has found that increasing your magnesium intake can help with the frequency of night time leg cramps, especially for pregnant women. Health experts recommend getting at least 300 milligrams of magnesium each day. A supplement can help you reach your daily allowance, but so can eating foods rich in magnesium, such as nuts, lentils, and quinoa.
Plan ahead for self-care if your leg cramps appear to be the result of strenuous exercise. Drink plenty of fluids and eat a well-balanced meal before heading out for a long run. Many athletes suggest eating a potassium-rich banana once you reach the finish line.

Controlling Type 2 Diabetes With Mindful Eating

Changing how you think about food can help you manage your blood sugar levels, weight, and overall health.

Eating right is the key to managing type 2 diabetes. Good food choices are critical for people with diabetes who want to reduce their risks for heart disease, stroke, and other health problems caused by diabetes.
“When someone is diagnosed with type 2 diabetes, they often have a sense that eating and food are things to be conquered,” says Michelle May, MD, a board-certified family physician who practices in Phoenix. That feeling can seem overwhelming. In fact, says Dr. May, some people may eat before they are hungry, motivated by the fear of having hypoglycemia, or low blood sugar. For better control of diabetes, May counsels her patients to employ mindful eating techniques, an approach to food that can help them manage their diets and their lives.
Mindful eating focuses on tuning in to one’s body to recognize basic hunger signals and notice early hypoglycemic symptoms, like feeling dizzy or shaky, and then eating with increased awareness — paying attention to every bite of food. “You have to be prepared to eat when you need to, to respond to your body’s signs,” says May.
Mindful Eating Ends Diabetes Diet Frustrations
May describes mindful eating as “eating with intention and attention.” Instead of thinking about “being good” or adhering to a diabetes diet, May says diabetes patients should be thinking about why, when, what, and how they eat.
A diabetes patient using mindful eating techniques may express intention as “I want to feel well,” “I want to be healthy,” or even “I want to enjoy the food at this party.” Mindful eaters pay attention to the eating experience by “being in the present moment and noticing how good the food tastes,” says May, “and [being aware that] as you eat, the enjoyment decreases as you get used to the flavors and become sated.” That’s your cue to stop eating.
Paying more attention to when, why, how, and what you eat sounds easy. But “many things can influence your choices and your awareness,” May warns. Among the most common distractions to avoid are eating while driving, eating while watching television, and focusing on cleaning your plate rather than on the food itself. Such habits, May says, not only distract people from what they’re eating, but also from the simple pleasure of eating.
Using mindful eating makes the food you eat much more satisfying. People who are keenly aware of what and how they are eating are “more likely to enjoy flavors and textures and the ambience of the eating experience,” May says, and they may also enjoy their lives more fully. “If you eat too much, you feel lethargic and regretful; if you eat the right amount, you feel energetic, content, and ready for your next activity,” she explains. Slowing down can also help you fend off obesity — one study found that middle-aged women who rush through their food tend to be heavier than those who savor every bite.
Mindful Eating in Practice
Mindful eating can help you successfully manage diabetes and get your weightunder control, two problems that often go hand in hand. When you’re overweight, says mindful eating practitioner JoAnn Martin, 68, of Phoenix, all you think about is food — “what can I eat and when can I eat it?” With mindful eating, Martin learned how to get her food cues from her stomach rather than her head.
Martin is the mother of seven and had gained more weight after every pregnancy, peaking at 300 pounds. She has had diabetes for decades and started needing insulin injections in the early 1970s, eventually developing insulin resistance. “My sugar was so out of control,” says Martin, who realized that she had to lose weight to avoid risking her life.
After trying many other diets, Martin enrolled in May’s “Am I Hungry?” class, having heard about it through her health insurer. Though it took time for all the information she learned to register, eventually it clicked. By practicing mindful eating, Martin says, she was able to control what and how much she eats: “All of a sudden you get this little voice in your head that says ‘You can stop’ or ‘You’ve had enough.’”
Being conscious of when to put down the fork has enabled Martin to lose 60 pounds and get better control of her diabetes as well. As May explains, mindful eating can make you feel less like a slave to a diabetes diet and help you enjoy food in a healthy manner.

  • For optimum heart health, the American Heart Association recommends 30 minutes of moderate to vigorous aerobic exercise on most days of the week. If you can't get in 30 minutes all at once, you can divide your exercise routine into 10- or 15-minute segments. "Aerobic exercise improves heart and lung fitness and can impact many of the risk factors for heart disease," says Deb Sampson, RN, BC, clinical coordinator for cardiac rehabilitation at the Nebraska Medical Center in Omaha.

"Aerobic exercise improves heart and lung fitness and can impact many of the risk factors for heart disease," says Deb Sampson, RN, BC, clinical coordinator for cardiac rehabilitation at the Nebraska Medical Center in Omaha.
    • Walk It Out for Heart Health

      Number one on the top 10 for aerobic exercise is walking. Walking is enjoyable, safe, inexpensive, and easy to fit into almost anyone's busy day. You can get in walking time by walking to work, walking to the grocery store, and walking around your neighborhood. Aerobic exercises are those that use large muscles in a continuous, rhythmical manner over time, and walking is a great example of that, says Sampson.

      Exercise at Home by Climbing Stairs

      To get the maximum heart health benefit from any aerobic exercise, aim to reach between 50 and 85 percent of your maximum heart rate. Climbing stairs is an easy way to get into that target range, whether you do it at home or at the gym on a stair machine. To find your maximum heart rate, subtract your age from 220. If you don’t want to stop to count heartbeats, you can assume that you’re in your target rate if you can carry on a conversation while exercising without being too out of breath.

      Go for a Bike Ride

      The pumping motion of the large muscles in your legs is a great aerobic exercise for your heart. Either a road bike or a stationary bike will work for this exercise routine. Pedaling at home on a stationary bike can get you on the road to heart health when it’s too cold or too wet to cycle outside. The position of the seat and pedals are important to prevent injury when biking, so make sure your bike is properly adjusted for your body.

      Take a Swim

      Swimming is one of the best aerobic exercises around and the third-most popular sports activity in the United States, according to the U.S. Centers for Disease Control and Prevention. Two and a half hours of swimming per week will give you all the aerobic heart health benefits you need. Another advantage of this exercise routine is that swimming puts less stress on your bones and joints. That can be especially beneficial if you’re starting out a little overweight or have a joint condition such as arthritis.

      Go for a Spin on the Elliptical Machine

      Elliptical training machines are one of the fastest-growing aerobic exercise options. These machines are found in most fitness centers and are increasingly being purchased for exercise at home. The advantage of an elliptical machine for heart health is that it gives you both an upper- and lower-body workout at once. The elliptical leg motion mimics running with the lower impact of cycling. At the same time, the rhythmic arm movements get blood flowing to your back and shoulder muscles.

      Dance to Your Heart's Content

      Dancing your way to heart health makes for a rhythmic and aerobic exercise routine. All you need is good footwear, some space, and music that motivates you. A good aerobic beat is about 120 to 135 beats per minute. Dancing can range from high impact to low impact depending on your ability and preference, and you can dance with others in a class such as Zumba or exercise at home by yourself.

      Chill Out With Tai Chi

      According to a recent survey from the National Institutes of Health, 2.3 million adults in America used tai chi as a low-impact aerobic exercise routine in the prior year. Tai chi is an ancient Chinese form of exercise based on the martial arts. It uses slow rhythmic body movements combined with deep breathing and concentration, which is why it’s also called a "moving meditation." This exercise routine is great for both mind and body, including heart health.

      Stay Fit at Home With Wii Fit

      Playing interactive video games is a great option for exercise at home. Studies show that Wii Fit boxing, tennis, and bowling could increase your heart rate enough to qualify as aerobic exercise. "The American College of Sports Medicine states that Wii Fit does provide an effective form of exercise," says Sampson. Remember that to meet physical activity guidelines, you will need to play for about 30 minutes five days a week.

      Make a Splash With Water Aerobics

      Like swimming, water aerobics offers the heart-health benefits of a good aerobic exercise workout without causing as much stress on the joints as other exercise routines might. If you have conditions such as arthritis, knee pain, or are overweight, water aerobics may be the perfect exercise for you. Water exercises have been shown to improve the use of joints in people with arthritis without worsening symptoms, according to the Centers for Disease Control and Prevention.
