Cold Weather Basics. Cold Weather Risks. Cold Weather Safety. Download a PDF version of the guide you can reference later. Get out your blankets, hot chocolate, and winter layers. This section answers all the basic cold weather questions, like:.
What temperature is considered cold weather? Cold weather, therefore, can be a little tricky to define. Cold weather is usually anything that requires a jacket or coat. What is freezing temperature? If you want to get technical, the temperature at which water freezes is 32 degrees Fahrenheit. Freezing temperature is also 0 degrees Celsius and How cold is extreme cold? There is no one-size-fits-all definition of extreme cold.
In the northern part of the U. There are several factors that cause cold weather. This tilt also produces a large temperature differences, as the rate of cooling is higher in the polar region compared to the equator.
This difference powers the jet stream that produces massive winter storms and cold outbreaks. Wind and moisture also impact how cold the weather feels. When you hear forecasters talk about bitter cold temperatures, you may also hear them mention the wind chill. What is the wind chill? Wind Chill is the cooling effect of wind blowing on a surface. We base wind chill on how much heat our exposed skin loses to cold temperatures and cold winds. Still wondering how wind chill works? The faster the wind is blowing, the more heat it draws from the body. If your body loses heat, your skin temperature will drop.
Eventually, that will cause you to have a low body temperature as well, which will not only make you feel cold but could adversely affect your health! You can check out the NWS Wind Chill Chart or simply reference our rendering of the chart below to help you understand what the wind chill is. The above chart uses advances in science, technology, and computer modeling to provide an accurate, understandable, and usable formula for calculating the dangers from winter winds and freezing temperatures.
The index does the following:. Technically, it gets colder everywhere there is a change of seasons from warmer season to colder. Of course, there are places that see colder temperatures than others. Did you know that the coldest place in the world on average is the East Antarctic Plateau? This frozen ice ridge between the summits of Dome Fuji and Dome Argus has seen temperatures of degrees Fahrenheit. While it gets cold in every state, there are some states in the U. That one is pretty easy to guess. Alaska is the coldest state in the U.
How low does the temperature go? In the winter months, Alaska regularly sees temperatures as low as degrees Fahrenheit. Here is a list of other states It s cold outside need heat are pretty cold and their average temperatures according to the World Population Review state rankings:. As you can see from this list, the cold states are the states that are furthest away from the equator. A cold front is the boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system.
Another way to think of a cold front is as the dividing line between an adcancing cold air mass — which is cold and dense — and the warmer air mass it replaces. ificant weather, including rain, snow, and thunderstorms, form on the front as the cold air lifts the warmer, moister air upwards. A polar vortex is a low pressure area that is present over the poles throughout the year. We call it a vortex because the low pressure area circulates.
Typically, the southern extent of the vortex goes no further than degrees latitude. Occasionally, the jet stream amplifies and a pocket of cold air moves north to south into lower latitudes. This is when very cold — often dangerous — temperatures occur. While plenty of people love winter and cooler weather, there are dangers of cold weather that can risk your health.
The human body has an average core temperature of To maintain this temperature, the surrounding environment needs to be 82 degrees Fahrenheit. The right clothes can help you keep warm, but low body temperature because of cold or extreme cold conditions can be life-threatening.
The biggest cold weather risks that can adversely affect your health are:. What is frostbite? Frostbite happens when your skin literally freezes. Most of the time, people catch frostbite when they leave areas of their skin exposed in cold and windy winter weather. Frostbite temperatures — or a temperatures at which most people can suffer from frostbite — happen from 31 degrees Fahrenheit and below.
How long does it take to get frostbite? Well, that depends on how cold it is and how exposed you are. Frostbite is very common in body parts like fingers, toes, ears, nose, and the face.
Frostbite on It s cold outside need heat of these places may look like:. Besides looks, there are the other warning s of frostbite you should be aware of:. You might not know this, but there are actually three stages of frostbite. Depending on the stage, frostbite can look different or present different symptoms.
While some people use the terms minor frostbite and major frostbite, those are not actual frostbite stages according to the Mayo Clinic. Frostnip is mild frostbite that irritates the skin. If you are suffering from mild frostbite, you may experience redness in the affected area and a cold feeling, followed by s.
When you contract superficial frostbite, you skin will feel warm. This is a of serious skin involvement. During superficial frostbite, a fluid-filled blister may appear 24 to 36 hours after rewarming the skin. The most serious frostbite stage, deep frostbite can cause complete numbness. As the cold impacts your epidermis, dermis, and sub-cutaneous tissue, your ts or muscles may stop working. Large blisters can form 24 to 48 hours after rewarming. Afterward, the area turns black and hard as the tissue dies.
Gangrene can also develop, placing you at high risk for infection. Also known as third-degree frostbite, this is the most serious and can cause permanent tissue damage. Treating frostbite starts with getting indoors as quickly as possible. Once indoors, assess where you frostbite is. If you have frostbite on your feet or toes, do not walk. This can cause more damage. The first thing you should do is get into a warm bath. Wrap your face and ears in a moist, warm, towel.
You should also remain as calm as possible. Depending on your stage of frostbite, you skin may look red and swollen. If you skin is blue or there is any other indication that you are suffering from deep frostbite, go to a hospital as soon as possible. Instead, put your hands in your armpits or hold onto another person or animal. If available, drink warm liquids and put on extra layers of clothes. That title belongs to hypothermia. What is hypothermia? Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce it. This in a dangerously low body temperature below 95 degree Fahrenheit.
Q: At what temperature can you get hypothermia? A: 95 degrees Fahrenheit or below. Anyone can catch hypothermia and it can be deadly. According to the CDC, approximately 1, people die of hypothermia each year. Most of the victims are seniors.
Similar to heat illnesshypothermia makes it difficult for your body to function properly. When your body temperature drops this drastically your heart, nervous system, and other organs are compromised. If left untreated, hypothermia can eventually lead to complete organ failure and even death. Most people get hypothermia from exposure to cold weather conditions or immersion in cold water. However, prolonged exposure to any environment colder than the body can lead to hypothermia.
The simple answer is: minutes. It really depends on the cause, how your body is losing heat, and any risk factors you have. Hypothermia can develop in as little as five minutes in temperatures of degrees Fahrenheit. At degrees Fahrenheit, hypothermia can set happen in about 10 minutes. It all depends! You should call if you think you or anyone else is experiencing hypothermia.
The first of hypothermia is confusion or an inability to concentrate. You can also feel dizzy as a result of reduced blood flow to the brain. This makes hypothermia very dangerous.
Here are the symptoms of hypothermia you should know:. Since death by hypothermia is possible, quick hypothermia first aid action is required. Treating hypothermia relies on being overly cautious. If you or someone else has a temperature below 96 degrees Fahrenheit, feels cold or sluggish, or is having trouble thinking clearly, call an ambulance immediately.
Getting to the hospital is very important. If you are with someone who you suspect has hypothermia and are waiting for an ambulance, lie close to them and cover up with thick blankets. The hotter you get, the more warmth you can give the other person. Be sure not to rub the person or handle him or her roughly.
Always seek medical attention first when dealing with suspected hypothermia and use your body heat to keep the victim warm until help arrives. Hyperthermia is very different from hypothermia. Therefore, the body is absorbing or producing more heat than it dissipates. You can learn about more heat-related illnesses by reading our Heat Guide. A lot of people associate cold weather with cold season. But does the weather make you sick, really? The weather is not what makes you sick.
The viruses that cause the common cold and flu spread through the air when someone does not cover a cough or sneeze. They can also spread when a person touches a contaminated surface and then touches their mouth, eyes, or nose. The same precautions recommended to stop the spread of COVID, including social distancing, washing hands frequently, wearing a face mask in public, and staying home when feeling sick help stop the spread of colds and the flu, too.
Even though we briefly touched on the cold weather dangers of frostbite and hypothermia, there are so many other cold weather safety tips out there!It s cold outside need heat
