Global Warming Increases Heart Disease Say Researchers

Heatwaves during 2003 in England and France swelled the numbers of those with heart conditions. In France 11,000 people died in the first half of August in that year when the temperature peered over 40C. Many deaths occurred from cardiac problems relating to heart ailments other than a heart attack.

Record temperatures in the UK also led to an extra 2,000 deaths, and experts predict heart mortality rates will increase as the effects of global warming worsen.

Researchers Say Action on Greenhouse Gasses Will Improve Health

An accompanying editorial, written by Dr Paola Michelozzi and Manuela De Sario of the Lazio Region Department of Epidemiology in Rome, said that health problems associated with heatwaves would outweigh any health benefits from global warming. They also said that action to reduce greenhouse gas emissions by lifestyle choices would improve health.

For example saturated fat consumption would be lowered if diets included fewer animal products that lead to greenhouse gas emissions through grazing. Healthier diets would reduce the rates of heart disease and be a key part of a strategy for greenhouse gas management.

British Heart Foundation Advise on How to Counter Cold Winters

The British Heart Foundation have responded to the study by warning heart patients they should stay warm in winter. Increased risk from heart problems can be countered by wearing suitable clothing and keeping houses sufficiently warm.

A senior cardiac nurse for the charity told the bhf.org.uk website “Although the increased risk is small, if there is a nationwide drop in average temperature it could equate to a significant number of heart attacks each day... This timely piece of research reminds us that older people and anyone with heart disease should keep warm in their homes after the summer draws to a close.”

Low temperatures last winter resulted in more ‘excess deaths’ - the amount of those who died compared to the same time in previous years - than in over a decade.

Safeguard the Achilles

One of the most painful tendon injuries is Achilles. But there are also ways to avoid these injuries. Here are some of them: You’ll feel a burning and piercing in the tendon above your heel and it can even make a crackling sound when you move it. Any higher up your calf and it’s more likely that you’ve strained or pulled a muscle. Rupturing your Achilles tendon is a exceptionally painful experience and you’ll know when you’ve done it. Your Achilles tendon connects your calf muscles to your heel bone and is made of thousands of individual fibers of collagen. Restricted blood flow to this area slows repair and pain will worsen if you keep training . Four important factors in healing the Achilles are: rest, ice, compression and elevation. If your tendon is harmed take a break from all weight bearing sport (except swimming) for at least 2 weeks. You can recover from mild injury in a couple of weeks but a severe one can take 5 months. In order to prevent Achilles injury in

Diabetes Food Pyramid

This diabetic food pyramid functions in a similar way to the regular food pyramid. One of the main differences is that the diabetic food pyramid focuses on limiting sugar intake . Diabetes is a disease that prohibits people from eating sugar at the same levels that they used to. This does not mean that all diabetics have to avoid sugar like vampires avoid the sun! Some people have mild cases that enable them to eat sugar once in a while. Others have to avoid it at all costs. The diabetic food pyramid is a lifesaver to many people. Just by looking at the pyramid they can tell which foods to eat and which ones not to. It also suggests serving sizes and suggestions for planning whole meals. The diabetic food pyramid has six categories of food groups. At the bottom the main group is grains, starchy vegetables, and beans. The second grouping on the diabetic food pyramid includes vegetables and fruits . The third includes diary products, meats and other sources of protein. At the t

Causes of Easy Bruising: Reasons Why People Bruise Easily

Bruising , a reddish or purple discoloration under the skin, most often results from trauma to the small blood vessels, called capillaries, but can also occur spontaneously. How and Why Bruises Occur Blood leaks out of the capillaries and accumulates under the skin, gradually absorbing over several days. Bruising most often occurs because people run into objects or experience other trauma. Most bruising is easily explained, but frequent bruising that occurs without obvious cause needs prompt investigation, since several serious diseases can cause bruising. In general, women bruise more easily than men. How Aging Increases the Risk of Easy Bruising Bruising increases as people age for several reasons. Skin thins as people age and the capillaries become more fragile. The layer of fat that cushions blood vessels and protects them from injury becomes thinner as well. Older people often take medications and supplements that thin the blood and contribute to easy bruising. Visi
