With 36 degrees Celsius and almost cloudless skies - and these are forecasts - around 1 pm a woman in light clothes will feel above 44 degrees Celsius in the sun. A girl dressed in dark will roast at almost 60 degrees. If she chooses a neutral, for example, beige color of clothing, then the physiological temperature that she will withstand will be a little over 53 degrees Celsius. How can we know?
Biocalculator calculates important parameters
A Polish scientist has developed a system to estimate the temperature that a person feels, the amount of water lost by the body per hour, and the safe time to stay in the sun and in a shaded place.
- The climate calculator calculates all this, taking into account the temperature and humidity, wind speed and cloudiness, date, time and geographical location, - explains prof. Krzysztof Blazejczyk from the Institute of Geography and Spatial Planning of the Polish Academy of Sciences.
The biocalculator also takes into account the color of clothing: light, neutral or dark. The differences are huge. And they concern not only physiologically perceived temperature.
A woman in white (light) clothes with the above parameters - we remind you: 36 degrees - will feel over 44 degrees in the sun, within an hour her body can lose almost 594 grams, or more than half a liter of water, and the heart rate in these conditions increases up to 102 beats per minute.
According to the MENEX 2005 model, the safe time in a sunny place is 101 minutes. This time is shortened when the girl is dressed in black. Under the same meteorological conditions - 36 degrees Celsius - the physiologically perceived temperature in a sunny place is 59.6 degrees, within an hour the body can lose more than 700 grams of water; safe time in the sun - 56 minutes (in a shaded place - 169).
For our safety in such tropical temperatures, of course, not only color matters. Remember: the skin and eyes need to be protected from the sun, the body needs to be moisturized.
A few examples of weather conditions are below.
Here’s what the physiologically perceived temperature promises
Katowice. In the forecast for July 20 at 13 - 33 degrees, wind speed 7 km / h (1.9 m / s), cloudiness 1/8 (in oktants), humidity 30%. With a nearly cloudless sky, in the case of a woman dressed in white, the perceived temperature in a sunny location is 41.2 degrees Celsius. If it turned out black or beige (neutral), respectively - 56.8 or 50 degrees.
Warsaw. Forecast for July 20 at 13 - 31 degrees, wind speed 14 km / h (3.8 m / s), cloudiness 1/8 (in octants), humidity 40%. The perceived temperature in a sunny location calculated by the bioclimatic calculator for a woman is: 38 degrees with light-colored clothes, 47.3 degrees with neutral-colored clothes and 54.4 degrees with black clothes.
Gdansk. July 20 at 13 - forecast 29 degrees, wind speed 7 km / h (1.9 m / s), cloudiness 1/8 (in oktants), humidity 50%. The perceived temperature is a sunny place, calculations for a woman are 36.8 degrees with light clothes, 46.1 degrees with neutral clothes, 53.2 degrees with black clothes.

We’re stuck in the heat. Remember that the sensation of temperature also depends on the color of the clothing.
