Dengerous virus

People infected with the virus suffer from high fever, strong headaches and muscle pain which can cause bleedings. Dengue fever is a constant threat. If you're planning a holiday in the tropics, get informed about dengue. Transmitted by mosquitoes, dengue affects between 50 and million people a year in popular holiday destinations such as Thailand and India.

But it's more of a problem for the 2 billion people who live in areas that are threatened by dengue fever. Being diagnosed with cancer is a shock that hits you hard. And yet almost half of all cancer cases could be prevented.

Smoking alone triggers about every fifth tumor. The toxic cigarette smoke does not only cause lung cancer but many other kinds of tumors as well. Smoking is the most frequent self-imposed cause for cancer, but not the only one. In second place of cancer-causing agents: obesity. Why it causes cancer? Enhanced insulin levels increase the risk of almost all sorts of cancer, especially when it comes to kidney, gall bladder, and oesophagus cancer.

Overweight women produce increasing amounts of female sex hormones in their fat tissue and hence have a higher risk for uterine or breast cancer. People who don't move enough are especially likely to get cancer. Long-term studies show that exercising prevents tumors. After all, working out lowers the insulin levels while preventing you from gaining weight. Even just going for a walk or a bike ride makes a big difference.

Alcohol promotes tumors in the oral cavity, the throat and the oesophagus. The combination of smoking and drinking is especially dangerous and increases the risk of cancer up to a hundredfold. Red meat can cause intestinal cancer. The exact cause has not yet been determined, but long-term studies show a significant correlation between the consumption of red meat and intestinal cancer.

Beef is especially dangerous, but even pork can cause cancer to a minor degree. Meat consumption increases the risk of cancer one and a half times. Fish, however, prevents cancer. When barbecuing meat, carcinogenic substances are released, such as polycyclical aromatic hydrocarbons. It has been proven in animal experiments that these chemical compounds can cause tumors.

However, long-term studies with humans have not yet unambiguously proven the same. A good diet consisting of vegetables, fruits and dietary fibers can prevent cancer. However, when conducting long-term studies researchers found that a healthy diet has less impact on cancer prevention than previously assumed.

It only decreases the risk of getting cancer by a maximum of 10 percent. While sunscreen protects the skin from sunburn, the skin absorbs too much radiation as soon as it starts getting tanned. X-rays harm genomes. With an ordinary radiogram the exposure is only minor. Magnetic resonance imaging is harmless. Human papillomaviruses can cause cervical cancer. Hepatitis B and C can cause hepatocytes to degenerate.

The bacterium helicobacter pylori pictured above settles in your stomach and can cause stomach cancer. But not all hope is lost. You can get vaccinated against many of these pathogens and antibiotics help fight helicobacter pylori.

The oral contraceptive pill slightly increases the risk of getting breast cancer, but at the same time it strongly decreases the risk of getting ovarian cancer.

All in all the pill is more protective than harmful, at least when it comes to cancer. Half of all cancer cases are caused by the wrong genes or simply age. Brain cancer is particularly likely to be inherited. The immune system needs many different types of fuel. Fruit and vegetables provide them. Your diet should be healthy and colorful: Oranges, red peppers, green leafy vegetables and red cabbage provide a potpourri of vitamins, and are especially rich in natural vitamin C.

In order to ensure your immune system is top-top, make sure you have all the necessary immunizations. Adults often forget to refresh vaccinations they had when they were young. Check if you need booster shots for tetanus, diphtheria, whooping cough, polio, hepatitis, pneumococcus, meningitis, measles, mumps, rubella, the flu and others.

Be sure to talk to your doctor! Scientific studies suggest that regular muscle training jogging, nordic or pole walking, taking a stroll , three times a week for 20 minutes can boost your defenses. But be careful: overdoing it can also drain your immune system. Sufficient sleep doesn't just allow your body to recuperate. During the slow-wave sleep phase, neurotransmitters are released and the immune system springs into action. Studies show that good spirits and a zest for life promote a strong immune system.

Laughing and playing don't just provide for a better quality of life, they also boost the body's defenses. Negative stress activates the release of adrenalin and cortisol. These hormones can paralyze the immune system. Sensible stress and time management allows the body to rest and replenish new energy. Selective relaxation exercises like meditation, autogenic training and yoga can significantly boost the immune system. Taking walks in the fresh air gives you a change of temperature and exercise - both stimulate the body's defense systems.

Mucous membranes also benefit from improved circulation and the increased humidity makes it easier to fight off attacks. Studies have shown that burning up short chain sugars like fructose and glucose uses up many vitamins that are no longer available to the body.
