Explain why some people are more sensitive to temperature changes and how to cope with it.

In short (click here for detailed version)

Some people are more sensitive to temperature changes due to their metabolism, blood circulation, or ability to regulate body temperature. To cope with this, it is recommended to dress appropriately, maintain a stable temperature at home, and consult a doctor for specific needs.

Physiological reasons for sensitivity to temperature changes

Some people experience temperature differently because their ability to thermoregulate is more or less effective. The body adjusts its temperature by manipulating blood vessels, which, depending on the individual, dilate or contract more or less quickly. If your vessels dilate rapidly, you will quickly feel warm, flush, and sweat easily; conversely, if your blood circulation struggles to adapt, you cool down quickly, your extremities become cold, and you shiver more easily. Thermal sensitivity also varies according to body fat: more fat acts as insulation but makes thermal regulation more complicated when you're hot. Basal metabolism also plays a role: some organisms naturally burn more energy, producing more body heat, while in others, it's the opposite. Lastly, of course, age clearly plays a part: older adults and very young children have more difficulty stabilizing their temperature, making them particularly sensitive.

Influence of lifestyle on thermal perception

Our diet influences our thermal sensitivity. A hearty or spicy meal can quickly raise body temperature and intensify feelings of warmth. Conversely, a diet that is too low in calories limits our body's ability to produce sufficient heat. Similarly, sedentary behavior plays a significant role: moving regularly improves the body's thermal regulation, while sitting all day behind a screen often makes one more sensitive to cold or drafts. Fatigue also plays a part: the less well or sufficiently we sleep, the less effectively our body regulates temperature. Finally, regular exposure to temperature variations is very important. Someone who continually moves from a heated couch to an air-conditioned car will have a harder time coping with sudden changes than a person who is accustomed to facing heat or cold every day.

Medical conditions increasing thermal sensitivity

Some diseases make it difficult to regulate body temperature. This is the case with hypothyroidism. When the thyroid is sluggish, the body struggles to produce enough heat, leading to a constant feeling of cold. Conversely, in the case of hyperthyroidism, the thyroid is overactive: heat, excessive sweating, and guaranteed thermal discomfort. People suffering from anemia (iron deficiency) are also sensitive, as they transport oxygen less efficiently in their blood and therefore produce less heat. Nervous disorders like multiple sclerosis can distort the messages sent to the brain regarding temperature and drastically increase thermal sensitivity. Diabetes, by affecting blood circulation and nerve function, also disrupts the regulation of body heat, causing unpredictable reactions to temperature changes.

Practical tips to limit discomfort from temperature fluctuations

To better manage your comfort in response to temperature variations, start by adopting the simple method of layering clothes instead of wearing a single heavy jacket. This way, you can easily adjust by, for example, removing a sweater if you get too warm. Also, think about choosing materials like cotton or merino wool, which breathe well and naturally regulate your body temperature. Don't forget to drink water regularly, as your hydration level affects your thermal sensation, even when it's cool. Make sure you have good insulation in your home to avoid constantly experiencing unpleasant temperature changes as you move from one room to another. Finally, some moderate exercises, like a daily walk or gentle yoga, can help your body better adapt to these variations.

Technological solutions for better managing thermal sensitivity.

To maintain comfort in the face of temperature variations, technology is lending a real hand today. Heated clothing, for example, comes with mini portable batteries to heat jackets or socks in just a few moments. Practical in winter. Smart fabrics with phase-changing capabilities automatically adjust their insulation based on temperature, preventing overheating or sudden chills. Otherwise, at home, smart thermostats also make a difference: you can control your heating with an app or your voice, to keep the temperature just right. Another great option is heated or cooled seats in cars that maintain personalized thermal comfort without turning on the air conditioning or cranking up the heat. Finally, to really manage personal temperature, gadgets like thermal bracelets also exist: they create a localized sensation of warmth or cold on the skin, as needed, to better manage sensitivity on a daily basis.

Frequently Asked Questions (FAQ)

1

Are there foods that can help better tolerate temperature variations?

Sure! Here’s the translation: "Yes, certain foods like hot soups, spices (ginger, cinnamon, or chili), and hot beverages temporarily enhance the sensation of thermal comfort due to their vasodilating action or their immediate warming effect."

2

At what age do we observe an increased sensitivity to temperature changes?

It is often observed that sensitivity increases around the age of 60, as the body's thermal regulation tends to decrease naturally due to the aging of blood vessels and a decline in basal metabolism.

3

What clothing should be favored if one is particularly sensitive to temperature changes?

It is advisable to adopt the principle of multiple layers, allowing you to easily adjust your outfit according to the outside temperature. Favor breathable natural materials such as merino wool or cotton, as well as thermoregulating technical fabrics.

4

Do hormonal changes influence the perception of heat or cold?

Yes, significant hormonal fluctuations such as those experienced during menopause, pregnancy, or thyroid disorders affect body temperature regulation, which can suddenly cause hot flashes or increased sensitivity to cold and heat.

5

Why do some people always have cold hands and feet?

This may be due to poorer peripheral blood circulation, nerve disorders, or Raynaud's syndrome, which leads to excessive vasoconstriction in response to low temperatures. Wearing warm clothing and regularly engaging in physical exercise can help improve this phenomenon.
