It could be fatal. It is commonly held that the maximum temperature at which humans can survive is 108.14-
How much heat can the human body endear? According to scientists, the body works best within a narrow range of body temperature - 36C to 37.5C. Once 40C is reached, it can be dangerous even with low humidity levels and now as the temperature is near to 50C the situation is critical.
Severe hypothermia is life-threatening
Mild hypothermia (32 to 35°C body temperature) is usually easy to treat. However, the risk of death increases as the core body temperature drops below 32°C. If core body temperature is lower than 28°C, the condition is life-threatening without immediate medical attention.
While human body cells start to die anywhere 46-60 degrees celsius, temperatures of around 50 degrees is when most irreversible damage to cells start as the proteins within begin to coagulate.
The wet-bulb temperature that marks the upper limit of what the human body can handle is 95 degrees Fahrenheit (35 Celsius). But any temperatures above 86 degrees Fahrenheit (30 Celsius) can be dangerous and deadly.
Precautions. Research has shown that when the temperature gets to 35C, accompanied by high humidity, health is put at danger. Once 40C is reached, it can be dangerous even with low humidity levels. Suffice to say at 50C, the risk is even higher.
Our studies on young healthy men and women show that this upper environmental limit is even lower than the theorized 35 C. It's more like a wet-bulb temperature of 31 C (88 F). That would equal 31 C at 100 percent humidity or 38 C (100 F) at 60 percent humidity.
Touching hot surfaces
1st Degree Burn (minor burn): Non-metallic 85°C brief contact. Metal 60°C brief contact. Metal 50°C hold.
A deep red fire is about 600–800° C (1112–1800° F). An orange-yellow fire is about 1100° C (2012° F). A white flame is hotter than both, having temperatures of 1300–1500° C (2400–2700° F). A dazzling white flame is the hottest flame of all, with a range of 1400–1650° C (2600–3000° F).
In July 1913, observers in Furnace Creek, California—Death Valley—watched the thermometer reach 56.7°C (134°F) and declared it to be the highest temperature ever recorded on Earth.
At minus 40 to minus 50 F (minus 40 to minus 45 C), hypothermia can set in in just 5 to 7 minutes, he said. A drop in body temperature prevents critical organs from working properly — including the brain and heart, according to the Mayo Clinic.
Humans are able to endure hotter temperatures if the humidity is low. Adults have survived 10 minutes at 300 degrees in burning buildings and deep mines. 120 degree cars can be deadly in minutes, and children can't handle such temperatures.
The record for the lowest body temperature at which an adult has been known to survive is 56.7 F (14 C), which occurred after the person was submerged in cold, icy water for quite some time, John Castellani, also of USARIEM, said in 2010 interview.
Hypothermia is a condition brought on when the body temperature drops to less than 95°F. It can kill. For those who survive, there are likely to be lasting kidney, liver and pancreas problems.
Air is a very poor conductor of electricity and gets extremely hot when lightning passes through it. In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).
A wet-bulb temperature of 35 °C, or around 95 °F, is pretty much the absolute limit of human tolerance, says Zach Schlader, a physiologist at Indiana University Bloomington. Above that, your body won't be able to lose heat to the environment efficiently enough to maintain its core temperature.
In fact, as it spills out onto Earth's surface as lava, the runny rock's temperature is only a little lower than the hottest part of a candle flame: about 1200 °C. On the other hand, a big blob of lava contains many more bouncing particles than a small candle flame, so it has a lot more heat energy.
For blue flames, or flames with a blue base, you can expect the temperature to rise dramatically, hitting roughly 2500°C to 3000°C. A bunsen burner or oven hob are the most obvious examples of blue flames.
Purple flames come from metal salts, such as potassium and rubidium. It's easy to make purple fire using common household ingredients. Purple is unusual because it's not a color of the spectrum. Purple and magenta result from a mixture of blue light and red light.
At 118 degrees, human skin can sustain first-degree burns; a second-degree burn injury can occur at a temperature of 131 degrees. Human skin is destroyed when temperatures reach 162 degrees.
The reason for this is that the average person can touch a 140°F surface for up to five seconds without sustaining irreversible burn damage. ASTM C1055 determined that five seconds is the most probable contact time in an industrial setting.
Anything above 120°F is shown as scalding. Please also note that 120°F = 48.8888… °C or approximately 50°C.
New research suggests that, if the planet keeps warming at current rates, much of the top third of Australia could soon be too hot for people to live in.
Adults. Call your health care provider if your temperature is 103 F (39.4 C) or higher. Seek immediate medical attention if any of these signs or symptoms accompanies a fever: Severe headache.
Taking the Moon's Temperature
Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). The Moon's poles are even colder.
