As temperatures soared to record-breaking highs, hitting 37C in central regions, sweltering Russians have been throwing themselves into rivers and lakes to cope with the heat.
But many have ignored warning signs about hidden dangers at certain spots or drank alcohol before swimming, putting themselves in danger.
Russia's emergency ministry confirmed that almost 300 people have drowned during the heatwave, with at least 63 people dying in one day alone.
A ministry spokesman said: "Last week, 285 people died in Russia's waterways. The main reason for people drowning is swimming in places that are not equipped and the use of alcohol."
Russian weather forecasters said the country had not experienced such a prolonged heatwave since 1981.
Moscow's City Hall had to send out trucks to water the streets after reports that in some areas people's shoes were getting stuck in melting tarmac.
Drowning is a major problem in Russia, with more than 3,000 people dying while swimming last year alone.
From On Scene-> "Drowning Doesn’t Look Like Drowning"
The new captain jumped from the cockpit, fully dressed, and sprinted through the water. A former lifeguard, he kept his eyes on his victim as he headed straight for the owners who were swimming between their anchored sportfisher and the beach....”Move!” he barked as he sprinted between the stunned owners. Directly behind them, not ten feet away, their nine-year-old daughter was drowning. Safely above the surface in the arms of the captain, she burst into tears, “Daddy!”
...Drowning is not the violent, splashing, call for help that most people expect. The captain was trained to recognize drowning by experts and years of experience. The father, on the other hand, had learned what drowning looks like by watching television. If you spend time on or near the water (hint: that’s all of us) then you should make sure that you and your crew knows what to look for whenever people enter the water. Until she cried a tearful, “Daddy,” she hadn’t made a sound.
In ten percent of those drownings, the adult will actually watch them do it, having no idea it is happening (source: CDC). Drowning does not look like drowning – Dr. Pia, in an article in the Coast Guard’s On Scene Magazine, described the instinctive drowning response like this:
1. Except in rare circumstances, drowning people are physiologically unable to call out for help. The respiratory system was designed for breathing. Speech is the secondary or overlaid function. Breathing must be fulfilled, before speech occurs.
2.Drowning people’s mouths alternately sink below and reappear above the surface of the water. The mouths of drowning people are not above the surface of the water long enough for them to exhale, inhale, and call out for help. When the drowning people’s mouths are above the surface, they exhale and inhale quickly as their mouths start to sink below the surface of the water.
3. Drowning people cannot wave for help. Nature instinctively forces them to extend their arms laterally and press down on the water’s surface. Pressing down on the surface of the water, permits drowning people to leverage their bodies so they can lift their mouths out of the water to breathe.
4. Throughout the Instinctive Drowning Response, drowning people cannot voluntarily control their arm movements. Physiologically, drowning people who are struggling on the surface of the water cannot stop drowning and perform voluntary movements such as waving for help, moving toward a rescuer, or reaching out for a piece of rescue equipment.
5. From beginning to end of the Instinctive Drowning Response people’s bodies remain upright in the water, with no evidence of a supporting kick. Unless rescued by a trained lifeguard, these drowning people can only struggle on the surface of the water from 20 to 60 seconds before submersion occurs.
