Can You Build Cold Tolerance? Doctors Explain

Cold weather can pose a serious threat to our health, particularly to elderly people and those with chronic illnesses. So it’s important to take steps to protect ourselves from cold-related health problems, such as hypothermia and frostbite.

One of the best ways to protect ourselves from the cold is to build up our cold tolerance. But is this really possible? Can we train our bodies to withstand colder temperatures?

We asked doctors to explain the science behind cold tolerance and provide tips on how to improve it and deal with cold weather.

Is cold weather good for you?

Cold weather is a topic of much debate, with some people claiming that it’s good for the body and others believing that it can cause a host of health problems.

In this section, we’ll take a closer look at the effects of cold weather on the human body and explore both the benefits and drawbacks.

First, let’s take a look at the benefits of cold weather. If you’ve ever wondered, “Why do I like the cold so much?” you might find your answer here.

• Boosts the immune system: Cold weather can help boost the immune system by exposing the body to mild stressors. One study found that moderate cold exposure can increase the production of white blood cells, which are responsible for fighting off infections.
• Improves mood: Cold weather can also have a positive impact on mood. According to one study, exposure to cold temperatures can improve mood in people with seasonal affective disorder.
• Increases metabolism: Cold weather can also help increase metabolism. Another study found that exposure to cold temperatures can increase the production of brown fat, which is responsible for burning calories.

While there are certainly benefits to cold weather, there are also drawbacks that need to be considered.

• Increases risk of hypothermia: Cold weather can increase the risk of hypothermia, which is a condition characterized by low body temperature. Hypothermia can occur when the body loses heat faster than it can produce it, and it can be life threatening if left untreated.
• Increases risk of frostbite: Cold weather can also increase the risk of frostbite, which is a condition characterized by freezing of the skin and underlying tissues. Frostbite can occur when the skin and tissues are exposed to freezing temperatures for prolonged periods of time and can lead to permanent tissue damage.
• Increases risk of cardiovascular disease: Cold weather can also increase the risk of cardiovascular disease. Research has found that exposure to cold temperatures can constrict blood vessels and increase blood pressure, which can increase the risk of heart attack and stroke.

Why are some people more resistant to cold than others?

The ability to tolerate cold temperatures can vary greatly from person to person. Some people seem to be naturally cold resistant, while others feel chilled at the slightest drop in temperature. In this section, we will explore some of the reasons why some people may be more resistant to cold weather than others.

Body fat

People with higher levels of body fat tend to have a better ability to tolerate cold temperatures. This is because fat acts as insulation, helping to keep the body warm. Researchers found that people with lower levels of body fat had lower core temperatures in response to cold exposure.

The location and type of body fat also play a role in cold tolerance.

Brown fat, also known as “good fat,” is responsible for burning calories to produce heat. People with higher levels of brown fat tend to have a greater ability to tolerate cold temperatures.

Hormones

Hormones also play a role in cold tolerance. Thyroxine, a hormone produced by the thyroid gland, helps to regulate the body’s metabolism, and it is also involved in the body’s response to cold temperatures.

Genetics

Some people may have inherited genetic variations that make them more resistant to cold temperatures. A study published in 2021 found that people with a specific genetic variation had a greater ability to tolerate cold temperatures.

Acclimatization

Exposure to cold temperatures can also play a role in cold tolerance. People who live in cold climates or engage in outdoor activities in cold weather may become acclimatized to the cold, which can increase their ability to tolerate it.

According to one study, people who were exposed to cold temperatures for prolonged periods of time had a greater ability to tolerate cold temperatures.

How to build cold tolerance

For some people, cold tolerance comes naturally, while for others, it may take some effort to build. In this article, we will explore some ways to improve cold tolerance.

• Gradual exposure: One of the most effective ways to build cold tolerance is through gradual exposure. This means slowly increasing your exposure to cold temperatures over time rather than all at once. This allows the body to adapt gradually to the cold, which can increase cold tolerance.
• Exercise: Regular exercise can help increase blood flow and metabolism, which can help the body stay warm. Additionally, exercising in cold temperatures can also help the body to become acclimatized to the cold.
• Proper clothing: Wearing the proper clothing is also essential for building cold tolerance. Layering is key to staying warm in cold temperatures, as it helps to trap heat close to the body. Having a base layer of moisture-wicking fabric, an insulating layer, and a waterproof outer layer will help keep your body warm.
• Hydration: Dehydration can cause the blood to thicken, making it harder for the body to circulate heat. Drinking plenty of water and avoiding alcohol and caffeine can help keep your body hydrated.
• Cold shower: It’s a good way to get the body accustomed to cold temperatures. Taking a cold shower can also help increase blood flow and metabolism.
• Cold water immersion: Immersing the body in cold water is another way to help increase blood flow and metabolism and help the body to become acclimatized to the cold.

It’s important to note that while these methods can be helpful in building cold tolerance, it’s still crucial to take proper precautions to protect against hypothermia and frostbite.

Make sure to consult with a doctor if you have any underlying health conditions that may be affected by cold weather.

What to do if you get cold easily in winter

Feeling cold easily in the winter can be a frustrating experience, but there are steps you can take to stay warm. Here are some tips if you are wondering how to deal with cold.

Wear proper clothing

Wearing the appropriate clothing is essential to avoid feeling cold. Layering is key, as it helps to trap heat close to the body.

Start with a base layer of moisture-wicking fabric, such as thermal underwear, add an insulating layer like fleece or wool, and finish with a waterproof outer layer to protect against wind and snow.

Make sure to keep your head, hands, and feet covered as well, as these are areas that are particularly susceptible to heat loss.

Stay active

Regular physical activity is another great way to keep your blood flowing and boost your metabolism. Exercising in the winter can be as simple as taking a brisk walk or going for a jog around the neighborhood.

Stay hydrated

Staying hydrated is also important for staying warm in the winter. Dehydration can lead to a range of serious health issues, as it causes the blood to become thicker and makes it harder for the body to maintain its temperature.

Use heat sources

Using heat sources such as a fireplace, space heater, or electric blanket can help to keep the body warm. Make sure to use these heat sources safely and in accordance with the manufacturer’s instructions.

Eat a healthy diet

Eating a balanced diet that is rich in fruits, vegetables, and whole grains can help to boost your immune system, keeping you healthy and more resistant to colds and flu. Make sure to include foods rich in iron in your diet if you get cold easily and don’t skip meals. Malnutrition and iron deficiency can cause you to feel colder than usual even in warm environments.

Conclusion

To sum up, tolerance to cold is the body’s ability to withstand cold temperatures. Some individuals may have a natural inclination toward it, while others may need to take specific steps to enhance it.

Gradual exposure, regular exercise, proper clothing, staying hydrated, taking cold showers, and cold water immersion are some ways to build cold resistance.

However, it’s crucial to take safety measures to prevent hypothermia and frostbite while attempting to build cold tolerance.
