Doctors told how to lower blood pressure without medication

High blood pressure is dangerous because it can lead to the development of cardiovascular disease and cause strokes. As you know, to lower blood pressure help medication. Also to improve the condition of patients, specialists develop special diet and advised to choose the right physical exercises.

But as it turned out, there is another simple way to avoid health problems. An international team of researchers found that lower blood pressure helps exposure to blue light.

The experiment involved 14 healthy men. Their entire body for 30 minutes once a day, subjected to exposure to blue monochromatic light at the wavelength of 450 nanometers. The next day was carried out a control experiment: participants were exposed also blue, but not monochromatic light, for 30 minutes.

Experts explain that for the health of blue light, unlike ultraviolet radiation, not dangerous. The same light present in the day of sunlight, is constantly entering the human body.

During light therapy, as well as two hours before and after the session, physicians recorded the number of indicators of volunteers – blood pressure, pulse, arterial stiffness, the degree of expansion of blood vessels, the level of concentration in plasma nitric oxide.

Then followed the analysis of indicators of the health of patients. It turned out that exposure to blue light reduced systolic blood pressure (also known as the “top” pressure) is almost eight millimeters of mercury. In addition, the participants increased heart rate. In the control test, such effect was not observed.

According to doctors, the General condition of patients was very similar to the condition observed in clinical trials when a person takes the drug to reduce the pressure.

However, it was discovered other positive effects. In particular, exposure to blue light reduced the so-called cardiovascular risk markers, including arterial stiffness. Moreover, the participants improved function of endothelial cells lining the inner surface of blood and lymphatic vessels. Also in plasma of volunteers increased the content of nitric oxide.

Scientists believe that exposure to blue light evoked release of nitric oxide in the bloodstream. When this decreased pressure and increased velocity of blood circulation.

Co-author Professor Christian Heiss (Christian Heiss) from the University of Surrey is confident that the blue light can become the basis of therapies that will help many patients to improve health. This treatment will reduce the dosage of drugs, and in some cases, perhaps, even abandon them (it all depends on how much you want to reduce the pressure).

“Wearable blue light sources can provide a continuous effect is real and practical. This would be especially useful for those whose blood pressure is difficult to control with medications, for example, for elderly people,” — said the Professor, his.

However, the feasibility, safety and long-term effectiveness of new treatment methods professionals remains to be proven in studies with a larger sample of participants, and not only healthy.

The scientific article with a more detailed description of this work published in European Journal of Preventive Cardiology.

Recently the doctors have set a new gold standard safe blood pressure readings.

We also add that this is not the first study of the impact of blue light on the human body. Previously, the authors of the project “Conduct.Science” (nauka.vesti.ru) reported that such therapy helps to lower stress levels. But the blue light that shines from the screens of gadgets, computers and televisions, destroys the retina of the eye.

With 2 simple knee Exercises, you prevent joint pain

Our knees need to withstand quite a lot: every Day, we bow down to you, on average, more than 1000 Times. Each time you walk the multiple rests of our body weight on them. The largest and most complex joints in spite of continuous load fit, we should be active.

Millions of people complain of inflamed, swollen or aching knees. No wonder: No other joint is daily burdened and stressed like this. Not just Sprinting, or skiing, it must keep the face of tremendous pressure: At each knee flexion the largest and most complex of our joints wearing the Seven – to-eight times our weight.

So it crunches in the short or long-each time you Bend or stretch, pinches or hurts, movement is important. A good Alternative to the gym or sports field offer aerobics or Zumba: The combination of dance and Fitness brings the body into swing, can the pounds and promotes flexibility and strength.

The benefit not least to the knees: Regular exercise also improves the metabolism and blood circulation of the knee joint. In addition, a strengthened muscles protects the knee joint injuries and diseases.

In order to prevent Overuse of the musculoskeletal system, we recommend a moderate, age-appropriate and not too intense workout. In the case of existing complaints of the feet or knee joints, you should avoid, however, be on sports completely, or with an orthopedic surgeon, a gentle approach discuss.

Two Exercises for healthy knees

1. Flat on your back and raise one leg. The foot towards the buttocks. After a few seconds stretch out. The Whole thing a dozen Times with each foot repeat.

2. Sit on the table and the legs swing freely. As a result, the joint is spread grease over the entire cartilage surface of the knee joint. Cartilage nutrition is significantly improved.

The best sports for healthy knees

Whether Zumba, Running, or Jogging – regular exercise, without excessive ambition, the best medicine is “”. Muscles, Tendons and ligaments to be strengthened in a healthy way – a slow warm – up and training. As particularly knee-friendly apply

  • Swimming
  • Hiking
  • Gymnastics or water aerobics

Simple measures in everyday life

Of the (knee)health and conducive to regular Cycling to work or for shopping. Improper loading, such as when Running can occur are virtually eliminated. All of the muscles that stabilize the knee, to be trained.

But smaller steps can achieve quite a lot. One of the simplest Precautionary measures: often times take the stairs instead of the lift. Each stage strengthens the muscles, invigorates the knee metabolism and thus prevents osteoporosis.

Long hours of Sitting in the car, office or TV chair increases the need to be active: Remains of a joint in a rigid Position, so that the cartilage layer is loaded permanently on a body and to lose excessive joint fluid. This happens more often in the day, so the risk of cartilage damage is increasing rapidly, as when a clothing is claimed always in the same place and a hole forms.

  • You can change as often as possible the work or the position of the seat.
  • Get up once in a while.
  • You are going short distances.
  • Stretch at your Desk more often the knee.

The less strain on the joints

In addition to a lack of exercise is a prolonged Standing “poison” for the knee. Because then the full body weight rests on the connection point between the upper and lower leg bones. Better time to take a breather in the Sitting load, and several times a day, the legs dangle. This promotes the formation of synovial fluid.

Should avoid, to the extent possible, longer Work in stop position (for example, when Mounting or crafts), as well as a strong knee flexion, so the cross-legged or with frequent Squatting. Problematic is also the following sports are:

  • Football
  • Handball
  • Squash
  • Tennis
  • Rowing
  • Skiing

In the case of rotational movements of the knee under load, typically for the Kick, or skiing, are the the cartilage protective menisci are especially prone to injury.

Instead of high shoes that make it difficult to straighten the joints, better flat shoes with soft sole wear. They dampen vibration while walking and protect the joints. The Same is true for an “acceptable” body weight. Because obesity is one of the main risk factors for osteoarthritis or other knee ailments.
