The Turkmen expedition of the Institute of Agrochemistry and Soil Science of the USSR Academy of Sciences moved to a new base in Tashkent. The driver B. Bulatov and B. Goenko equipment were instructed to transport the expeditionary property. July 24, they left the village, lost in the Karakum desert, and headed east.
The actions of the victims of the disaster in the desert, the construction of a sun shelter, the restriction of physical activity, the rational use of water supplies.
But at the appointed time, July 29, the car did not come to Tashkent. Only on the eightieth day did one of the ground rescue groups find a gas truck lost in the sand, and a few days later, 60 km from Sayat-Aji, found the bodies of the dead. From scanty notes in a notebook, it turned out that already on the second day, travelers were lost.
. That is why any physical activity in the hot season should be limited to a minimum. All work on the improvement of the camp, the search for water and food is carried out only at night, in the cool morning or evening hours. To take off all clothing is the person’s first desire when it gets hot. But in the desert this should not be done..
Clothing not only protects the skin from direct exposure to sunlight, but also significantly prevents the drying and overheating effects of hot air. At temperatures above 40 degrees, the wind not only does not cool the body, but also increases the convective intake of heat. And although a naked person feels subjectively as if better, more comfortable than dressed, as sweat evaporation intensifies, the dehydration process is significantly accelerated.
When the naked subjects were put in a heat chamber and, heating the air to a temperature of 35–52 degrees, the fan was turned on, blowing them at a wind speed of 2.5 m / s, then each of the participants in the experiment lost an average of 515 g of liquid per hour. But as soon as the subjects put on the burnus, the traditional clothes of the inhabitants of the deserts, water losses decreased to 340 g. But at the same time, the clothes should be well ventilated. So that the heat does not accumulate in the clothing area, the gates and cuffs are unfastened, the waist belt opens.
