The first big heat wave makes its way through Germany. The great cities report temperatures far beyond 30 degrees Celsius. The Cologne sweating currently at 36 degrees, and are thus the leaders. In addition, the forecasters expect the first tropical nights. The air cools at night, only very slowly and remains above the 20-degree mark. Healthy the is not all. However, you can guard against it and thereby prevent the circulation going in the knee. Dr. Ulrich Mayer-Runge, coordinator of the Central emergency room at the University hospital in Hamburg-Eppendorf. In an Interview with the star, he explains, what with the great heat in the body happen, how to in spite of tropical temperatures, healthy sleep, and why is the window closed during the day should remain.

Dr. Runge, in these days of hot air with temperatures up to 40 degrees Celsius, comes to Germany from the Sahara. What makes with our body?

Especially in the heat can lead to cardiovascular complaints. Due to the high temperatures, we lose a lot of fluid. To do this, the blood vessels expand. In the case of intensive solar radiation on the head of a so-called sun, threatening to also stitch. The patients may feel restless, many also complain of dizziness and headaches, some passed also.

When one speaks of a heat stroke?

As soon as the body temperature rises to 40 degrees Celsius and above. We observe that often people who drive at these temperatures, even sports. This can be life threatening. The physical strain combined with the heat the temperature-Regulation brings in the body of the rudder. We are no longer sweating and the heat accumulates. Signs of heat stroke, a high pulse, fatigue, low blood pressure but also seizures and hallucinations have. At the latest, then you should go out of the sun and in case of doubt, call an ambulance.

How can you prevent it from happening?

The A and o is to drink For a healthy adult, at least 2.5 to three liters a daily basis. In the case of physical activity must be added by the additional fluid loss due to sweating something else. Light and comfortable clothing allows air to the body circulate better, sun cream for the skin, and a head cover to protect in addition. Avoid the midday sun and run sporting activities in the early Morning or evening when it is cooler.

The meteorologists have also announced tropical nights with temperatures above 20 degrees. How do you sleep at such temperatures the healthiest?

In a light and airy sleep clothing that absorbs sweat. The best is to have a thin blanket or a bed sheet. It is also useful to put something in a drink to the bed. No Need to recommend, though, is a lukewarm shower just before bedtime.

Currently it is hotly debated whether or not to close the Windows in the apartment during the day to keep the room cooling or still-aired – if you can call at these temperatures at all. What is from a medical point of view make more sense?

Medical space temperatures of 26 to 28 degrees bad. You sweat a lot and lose a lot of fluid. I have to go down to to open the Windows at night and early in the Morning, when the outside temperatures are the lowest – otherwise, Windows and blinds to prevent direct sunlight from shining through the Windows.

Many people save on the weekend or after work to the pool or to a lake to cool off. Is it true that one should not jump after extensive sunbathing rushed into the water?

That’s true. Due to the large temperature difference between the heated body and the cooling water through the heat far provided blood narrow vessels very quickly. As a result, the blood pressure rises suddenly. This can lead to serious circulatory problems. In the worst case important organs are no longer be a failure of sufficient blood supply and circulation. There is also the risk that the Reflex of the air does not work any more continuation under water. We doctors speak, then, of an immersion shock.
