Faced with temperature changes, it adapts through physiological mechanisms that include vasodilation (in heat) and vasoconstriction (in cold). That is, changes in the caliber of the blood vessels, accompanied, as the case may be, by the release of heat and sweating or its conservation, with the reduction of the flow to the skin and extremities. These processes allow body temperature to be regulated.
However, sudden changes from hot to cold can lead to thermal stress, manifested by irritation, redness, burning sensation, itching and discomfort. In addition, the skin exposed to such conditions can suffer microdamages at the level of the skin barrier, increasing the risk of irritation and infections.
Exposure to cold
One of the most common effects of exposure to the cold is dryness of the skin. Low temperatures and low air humidity affect the upper layer of the skin, called the stratum corneum, which acts as a barrier against water loss.
The cold inhibits the activity of the sebaceous glands, reducing the amount of sebum produced. Sebum has an essential role in maintaining skin hydration, and its lack leads to dryness and cracks.
In addition to the cold, the use of indoor heating systems contributes to the decrease of air humidity, exacerbating the problem. Dry skin becomes more prone to peeling, redness and discomfort, affecting the quality of life. These manifestations are more pronounced in people with sensitive skin or with conditions such as eczema or atopic dermatitis.
An ideal product for this season is Hand & Body Lotion from Calivitawhich contains emollient and soothing ingredients, which deeply nourish the skin. It hydrates immediately and helps restore the skin barrier, combats dryness caused by temperature changes, being suitable for daily use.
People with sensitive skin feel the effects of temperature changes more acutely. Their skin barrier is often compromised, which makes the skin more vulnerable to irritating factors.
Going from hot to cold or vice versa can lead to irritation, burning sensation or intense itching. To protect it, it is recommended to avoid harsh products (soaps, detergents, perfumes) and adopt a gentle care routine.
Another risk factor is the dilation of capillaries during exposure to low temperatures, followed by a sudden contraction when the skin is reheated. This process can cause temporary facial erythema or even more severe conditions such as rosacea.
People with sensitive skin must pay special attention to the care routine and avoid products that contain irritants, such as perfumes or alcohol.
A key ingredient in maintaining the health of sensitive skin is vitamin Dknown for its anti-inflammatory properties. This helps to regulate the cell regeneration process and stimulates the production of natural lipids, essential for a hydrated and protected skin.
An ideal product for its supplementation is D-drops from Calivitaa liquid supplement with fast absorption. With a pure formula and controlled dosage, these drops are easy to administer and can be integrated into the daily routine to support the health of the skin and the whole body.
D-drops it is an excellent choice for people who want to maintain their optimal level of vitamin D, especially during periods when exposure to the sun is reduced.
The cold can trigger or aggravate various inflammatory skin conditions, including atopic dermatitis, psoriasis and urticaria. The decrease in temperature affects the barrier function of the skin, allowing the loss of transepidermal water and the penetration of allergens or irritants. In addition, the cold reduces the blood supply to the skin, affecting the healing process of the injuries.
Psoriasis, an autoimmune disease, can be exacerbated by cold weather due to lack of sun exposure and dry air. Similarly, cold urticaria, a condition characterized by the appearance of red spots and itching, is triggered by direct contact with low temperatures or cold objects.
Exposure to heat
Hot weather brings other challenges for the skin, especially due to exposure to ultraviolet radiation. UV rays penetrate the skin, causing sunburn, hyperpigmentation, premature aging and, unfortunately, increases the risk of all skin cancers.
Chronic exposure to the sun leads to the degradation of collagen and elastin, essential components for skin firmness and elasticity. This process, known as photoaging, contributes to the appearance of wrinkles and sun spots.
In addition, high temperatures can aggravate acne and other inflammatory skin conditions by increasing sebum production. Excessive sweating, combined with the bacteria present on the skin, can clog the pores, leading to the formation of pimples and irritation.
Sun protection is essential. Using a product with a high SPFcombined with a hydration routine, helps prevent sun damage. Vitamin E supplementationknown for its protection against oxidative stress, supports the health of skin exposed to UV.
vitamin e from Calivita it can enhance the hydration effects, considering its antioxidant properties, which contribute to cell regeneration.
The skin barrier, consisting mainly of lipids and dead cells, is the first line of defense against external aggressions.
Temperature changes affect its structure and functionality, and repeated exposure to cold or extreme heat can cause skin dehydration. Over time, this cumulative damage can lead to more sensitive skin and prone to infections or inflammation.
It is essential to pay more attention to maintaining the integrity of the skin barrier, by using moisturizing and emollient products adapted to the season.
Hydrolyzed collagen #glamUp from Calivita it is an excellent solution to support the health of the skin and the skin barrier. Its components support the regeneration of skin cells and restore the lipid layer, contributing to a stronger and more hydrated barrier. By increasing the elasticity and firmness of the skin, hydrolyzed collagen helps prevent dehydration caused by cold or dry air. At the same time, it supports the skin’s resistance against aggressive factors that can degrade its structure.
How do we improve these harmful effects of exposure to heat or cold?
It is important to adopt preventive measures and appropriate treatments:
● Hydration: we use moisturizing creams rich in lipids to protect the skin barrier, especially in the cold season. Natural oils, such as jojoba or avocado, are effective for dry skin (also contained in Hand&Body lotion)
● Sun protection, with cream with SPF of at least 30 throughout the year.
● Avoiding hot showers: Hot water dehydrates the skin, especially in winter. We opt for warm water and mild cleaning products.
● Humidifiers: Using a humidifier in the home can prevent excessive drying of the air in the cold season.
● Appropriate clothing: We will protect the skin from the cold by wearing gloves, scarves and warm clothes. In the warm season, we choose light and breathable clothing.
Temperature changes are therefore a constant challenge for the skin. From the dry cold of winter to the intense heat of summer, our skin has to face various conditions that can affect its health and appearance. Adopting personalized care routines and using seasonally appropriate products are essential for maintaining healthy and protected skin.
