What Is The Lowest Temperature A Human Can Survive Outside See Answer

Intuitively, extreme heat seems more deadly than extreme cold. Start a cozy fire, put on several layers of clothing, and indulge in excessive hot chocolate to gain warmth when the weather outside is frightful. But when it comes to heat, starting a fire is counterproductive, you can’t keep stripping off once you’re naked, and consuming too much cold food too quickly can cause brain freeze.

What is the lowest temperature a human can survive outside? When the internal body temperature of a person falls below 70 degrees, they will freeze to death. Although it’s uncommon, it’s possible to freeze to death in temperatures of 40 degrees. As the temperature drops, so does the amount of time you can endure the cold.

The Lowest Fahrenheit Temperature At Which A Human Can Survive

What is the highest and lowest temperature a human can survive? has no right or wrong answer. This will depend on how well the person can adjust to their environment. However, it is safe to assume that people will find temperatures below 95 degrees Fahrenheit intolerable.

The average person’s core body temperature will be between 98 and 99 degrees Fahrenheit, to put it simply. The human body can experience problems due to anything above or below that. Some may even be harmful to the individual’s health and way of life. Therefore, it’s crucial to maintain the body’s core temperature within a certain range.

Multiple things could occur when you expose the human body to low temperatures. Here are some things to watch out for:


One of the dangerous effects of being exposed to temperatures of 95 degrees Fahrenheit is that it can cause hypothermia in humans.

The body begins to use its energy to heat itself when a person is hypothermic. It will start shaking as its first action. If you do not quickly move into a warmer environment, your body will eventually tire itself out, leaving you feeling dizzy or sleepy. The situation begins to deteriorate at this point.

Organ failure is the worst scenario. The organs will begin to shut down as a result of the body’s inability to function properly. If a patient has multiple organ failures, they should seek immediate medical attention if they want a chance to undo the harm.


Another dangerous complication of exposure to cold temperatures is frostbite. Skin will start to deteriorate if exposed flesh is exposed to freezing temperatures for an extended period of time. In addition to causing skin death, the low temperatures will start to kill the underlying tissues in the exposed flesh.

That will result in permanent harm; the affected area of the body will turn black after developing frostbite. Then it will require amputation. Mountaineers who climb the tallest peaks frequently experience this. Their hands, feet, or nose may freeze if they don’t have any protection for these body parts.

The unfortunate fact is that everyday people who are out and about can also get frostbite. Always take precautions to keep yourself safe if you reside in or are visiting a region with subzero temperatures. Move as soon as you can into a warmer area if you notice that your nose is losing sensation or if this happens to any other body part.

The Lowest Celsius Temperature That A Human Can Endure

A person’s body temperature is typically between 98 and 99 degrees Fahrenheit. The temperature of the body’s core is between 36.5 and 37.5 degrees Celsius, if you convert this to degrees of Celsius.

You will become hypothermic if your body temperature drops below 35 degrees Celsius. In the previous section, I described a few hypothermia symptoms. But you also need to be aware of what will happen to your body if you keep it at a temperature even lower than 35 degrees Celsius.

You will pass out at 27 degrees Celsius. The inability of the body to function in cold weather may cause you to have higher blood pressure in your brain. If the core temperature falls to 21 or 20 degrees Celsius, death is unavoidable.

Although it sounds frightening, it is real. Even if the temperature drops below freezing, a person who is properly dressed won’t experience any problems. However, if someone is not properly dressed for the cold weather, many things could go wrong. So try your best to be ready for anything and everything whenever you go somewhere cold!

The Coldest Temperature A Human Can Breathe In

If it is below 10 degrees Fahrenheit or +12 degrees Celsius, you should cover your face with some sort of protection before going outside. Wearing a scarf is an easy way to prevent the cold air from entering your lungs while you breathe. You run the risk of developing frostbite on your lungs if you do not use any sort of covering over your mouth or nose.

Additionally, if you have a lung condition, you should exercise extra caution. Your heart and lungs may suffer from the cold air. Thus, when going outside in the cold, you need to exercise extra caution. See more about What Is The Highest Temperature A Human Can Survive Outside?

People Freeze To Death At Different Temperatures

When a person’s body temperature drops below 70°F, they will typically freeze to death. Your internal organs begin to shut down and suffer long-term damage at that point. People have, however, frequently endured body temperatures that are much lower than that. They can’t move and are essentially comatose, but they manage to live.

In 1999, while skiing, a woman by the name of Anna Bagenholm fell into a frozen stream. Her internal body temperature was 56.7°F when the rescuers discovered her body. Even though all the odds were against her, she managed to live. The lowest temperature a person has ever survived is that.

Could a person endure a body temperature that low? That was a unique situation, but I’m sure there will be other extreme situations in the future. The individual and their level of physical health are the only factors that matter.

Surviving Subzero Temperatures

A completely different beast emerges when attempting to endure below-freezing temperatures. When the temperature falls below -20 degrees, you have 10 to 20 minutes to live before you freeze to death. You can develop hypothermia in less than 5 minutes at lower temperatures (-40).

But freezing temperatures or being in a frozen lake are not prerequisites for dying from hypothermia. In 50°F weather, if you’re wet or there’s a severe wind chill, you could still pass away. A cool breeze accelerates the temperature loss, and the body loses heat 25 times more quickly in water.

90% of cold weather fatalities are thought to occur in favorable conditions. You should always prepare for the cold by dressing appropriately, and when you’re outside, make an effort to stay dry. You can survive much longer in the cold if you have the right equipment, but eventually the cold will get to you.

Consider your winter clothing as an insulation layer that stands between your body and the chilly air outside. Body heat is retained by your winter clothing, but only to the extent of the insulation layer. The internal temperature will quickly decrease if your body heat escapes more quickly than it is produced. Although hypothermia can develop at higher temperatures than most people realize, you will never reach the outside temperature.

Stages Of Hypothermia

The signs of mild hypothermia (95 degrees) frequently appear to be relatively minor. Shivering, general weakness, and slight confusion will start to affect you. Allowing your core body temperature to fall too low can be fatal.

  • If the temperature is below 95 degrees, you will begin to shiver, feel weak, and you could become slightly confused.
  • Below 91 degrees: Amnesia sets in as your body begins to shut down. It is impossible to remember any sense of survival.
  • Consciousness is lost below 82 degrees. Death is a real possibility if emergency medical care is not received.
  • Below 70 Degrees: Death is all but guaranteed when the body temperature falls below 70 degrees. There have been cases of profound hypothermia even though some adults have been known to survive.

Signs Of Hypothermia

Hypothermia increases your susceptibility to dehydration, hunger, and exhaustion. Cold weather has different effects on different people. One person in your group might experience hypothermia while everyone else is unaffected. The victim needs to be quickly warmed up after being quickly warmed up.

Early Warning Signs

  • Uncontrolled Shivering
  • Confusion and inability to follow verbal commands
  • Complaints of feeling cold
  • muscle cramps
  • General Fatigue

Dangerous Warning Signs

  • Slurred Speech
  • Confusion and inability to focus
  • violent outbursts
  • Stumbling and Falling
  • Coma and Death (If Left Untreated)

Our Bodies Can Get Colder Than You Think

Our bodies are actually quite tolerant of the cold having survived an ice age. Our vital organs are shielded from freezing temperatures by a few different mechanisms.

As soon as cold air touches your face, your body begins to constrict its blood vessels in an effort to insulate itself. Blood begins to move in the opposite direction, from the skin and extremities to the internal organs.

Your body safeguards its vital organs in the cold by doing this. Your fingers and toes will therefore become cold first on your body. While losing a few fingers won’t necessarily kill you, harming your vital organs can.

In an effort to generate heat, your body also starts to shiver. This additional movement will aid in increasing body temperature. Although it may seem bad, shivering indicates that your body is still resisting. Shivering indicates that you are entering the dangerous stages of hypothermia, so you should be even more concerned if it happens.

Water Speeds Up Hypothermia

Although hypothermia can happen in the open air, it happens most frequently in water. Falling into water while backpacking or camping during cold weather can be fatal. You must address the issue quickly because water quickly absorbs body heat.

Immediately after exiting the water, put on dry clothing and look for safety. Hypothermia will likely develop if your teeth start to chatter and you start to shiver. Put on some warm, well-kept clothing and make an effort to raise your core body temperature.

One of the best ways to raise your internal temperature is to jump into your sleeping bag in order to conserve body heat. Although synthetic sleeping bags are slightly heavier than down ones, they are much better at maintaining insulation when wet.

Treating Hypothermia

Get the victim to a shelter as soon as possible to treat hypothermia. To get out of the wind, rain, and cold, either use a premade structure or quickly construct a shelter. Replace any wet clothing with dry clothing and blankets.

Make a fire, and serve them a hot beverage with sugar. Sugar is simple for the body to burn, raising body temperature. To raise the blood sugar level, use emergency rations.

If you’re by yourself and start to shiver or exhibit other symptoms of hypothermia, you need to take action right away. Leave the wind or rain and take off your drenched clothing. Try to stay warm and use all of your emergency rations. Send out a distress signal right away, and if you can, start a fire.

You must take action right away to prevent hypothermia from progressing further because if you don’t, you risk losing consciousness. Keep in mind that you’ll experience a lack of motivation and hopelessness, but you must push through it. As soon as you can, make a call for assistance and start a fire.

The Bottom Line

According to Atlas Obscura, a person has ever survived a body temperature of 56.7 degrees Fahrenheit (13.2 degrees C). When she fell into a frozen stream while skiing in 1999, a woman by the name of Anna Bågenholm almost became a corpse. Could a person endure being even colder? Although we don’t know for sure, the BBC claims that if the water in your body’s cells actually freezes, it will form crystals that “expand and physically rupture the cell[s], causing death.”
