5 reasons for needing more vitamin C in hot climates
Some may think that vitamin C is only necessary in the cold seasons of the year, but the medical truth is that the body’s need for it may be greater in the hot seasons of the year and in sunny climates.
In addition to its vital role in strengthening the body’s immunity and helping it adapt to the environment during cold and hot climates, Vitamin C is one of the powerful antioxidants that protects the skin from harmful external factors, such as ultraviolet rays, pollution, and free radicals. It is also a vital essential nutrient. To manufacture collagen which keeps our skin soft and strong.
Everyone wants to show off healthy, radiant skin, but once it is exposed to sunlight and heat, the skin becomes dull, sweaty, and tired. However, by adding the right ingredients into a healthy nutrition routine, the skin can be protected and kept healthy. One of these ingredients that has multiple benefits for skin care in these debilitating climates is vitamin C.
The good thing is that vitamin C is found in high concentrations in the epidermis and dermis layers of the skin, but the vitamin content of the skin is depleted by factors such as UV rays, smoking and pollution; Therefore, increasing the intake of foods that contain vitamin C in high quantities helps compensate for the availability of vitamin C in the skin.
Vitamin C is also an influential factor in helping the body adapt and adjust to the heat
The importance of taking vitamin C
Here are 5 main reasons for the necessity of increasing your intake of vitamin C from natural food products in hot and sunny climates:
1. Compensation for loss due to sweating. During the summer, health experts recommend increasing our daily intake of vitamin C in order to balance the loss of ascorbic acid (vitamin C) due to excessive sweating and dehydration. Dr. Rachel Ward, a specialist in dermatology at the Cleveland Clinic, says that every person has sweat glands, which are located throughout the body, and during a single day in hot and sunny climates, the body secretes a few liters of sweat fluid, without one realizing it. In addition to water and salts, one of the most important components of sweat is vitamin C.
Some medical experts state that the presence of vitamin C in the sweat that the body secretes when appearing in hot and sunny climates is because vitamin C is one of the types of vitamins that dissolve in water (unlike vitamins A, E, K, and D, which dissolve in fats). Specifically, the amount of vitamin C in sweat fluid is 50 times greater than the amount of several types of vitamin B group and folic acid.
Experts also state that the presence of vitamin C in sweat fluid is necessary, given the vital role of vitamin C in protecting the skin from the effects of exposure to high temperature and sunlight, especially ultraviolet rays.
In addition to eating food products high in it, taking effervescent vitamin C supplement tablets, before and following physical activities that stimulate the secretion of more sweat in hot climates, is a safe way to ensure that its levels do not decrease, and it also helps in enhancing muscle recovery following physical exertion. .
Adapting to the heat
2. Enhancing the body’s ability to adapt to heat. The medical recommendation to increase the body’s supply of vitamin C in the hot seasons of the year (by eating food products rich in it) is not only due to increased loss of it through sweat fluid; Rather, vitamin C is also an influential factor in helping the body adapt and adjust to the heat. One of the mechanisms mentioned by some medical sources is the direct effect of vitamin C on increasing resistance to hot and humid temperatures by working to stimulate the work of the sweat glands and delaying the occurrence of fatigue and exhaustion in these glands. This helps increase the body’s ability to withstand heat and high temperatures.
Some studies have shown that by taking vitamin C, the body temperature remains more stable and lower, even in extreme heat. Research suggests that this may reduce the incidence of heat rash in some people, thus making dealing with the heat more bearable; Therefore, it is a wonderful vitamin that should be taken as a preventive measure once morest heat exhaustion. Vitamin C also helps the body’s immune system when high temperatures put the body under stress.
Hence, when the temperature starts to rise outside our bodies may need additional support. Good nutrition is the first priority to provide the body with natural vitamins, the first of which is vitamin C.

3. Protecting the skin from sunlight. None of us can completely prevent our skin from being exposed to the sun’s rays during the summer. However, vitamin C can protect and protect the skin from becoming a victim of harmful UV rays. Eating products rich in vitamin C, along with topical use of sunscreen, can double protection from sun damage.
Vitamin C has strong antioxidant properties that prevent oxidative damage caused by the activity of free radicals on the skin in these climates. Therefore, there is a phrase mentioned by some medical sources, which is: “The power couple for sun protection: vitamin C and sunscreen.”
To clarify, free radicals are unpaired (and therefore unbalanced) oxygen atoms, randomly searching for other atoms to stabilize themselves; So it will stick to anything, and skin cells are an easy target for it. It then causes a series of damage to those cells and the collagenous tissue surrounding them. Which leads to premature aging. As their name suggests, antioxidants are an “antidote to oxidation,” and help combat this damage directly. Vitamin C is a powerful antioxidant.
Prevent wrinkles
4. Promote collagen and prevent wrinkles. The sun’s ultraviolet rays are indeed very harsh on the skin, its freshness, smooth texture and moisture. It is also responsible for destroying the elasticity of the skin and reducing the availability of healthy types of collagen fibers in it. As a result, the skin is damaged, appears wrinkled and sagging.
To clarify, photoaging is a medical term for the early appearance of signs of sagging, spots, and roughness of the skin, as a result of repeated and prolonged exposure to ultraviolet rays. Repeated exposure to these rays leads to the decomposition of collagen and elastin fibers. The strength of these fibers and their connection with the tissue components of the skin layers is the secret behind the firm and youthful skin of young people.
Wrinkles in the skin are one of the skin changes resulting from a decrease in the level of elasticity in the connective tissues present in the skin. They appear especially in areas of the skin exposed to sunlight, such as the face, neck, hands, and forearms. Therefore, exposure to sunlight is the most profound factor in the development of wrinkles, especially in people with light skin.
The good thing is that there is a lot that can be done to slow the development of these wrinkles. Since vitamin C has anti-aging properties, it can help speed up the production of elastin and collagen, which in turn reduces the appearance of fine lines and wrinkles.
5. Reduce tan and give fresh skin. Sun tanning is a mild degree of “intentional” sunburn formation on the skin. Despite the widespread use of doing this, medical sources confirm that there is no safe way to increase skin tan, whether through sunbathing or lying in tanning booths that use artificial light. The US Food and Drug Administration also adds that increasing skin tan is not a way to protect the skin from being affected by sunlight later on.
The mechanism of skin tanning is that exposure of the skin to ultraviolet rays increases the production of melanocytes (skin pigment cells) of the skin pigment melanin. Consequently, the darkening of the skin color increases during the next 48 hours. That is, in fact, it is a sign that the skin has been damaged as a result of exposure to sunlight, and that the skin is trying to protect itself from the effects of the sun’s burning rays, by producing more melanin, which leads to tanning.
Vitamin C works to reduce the production of melanin, in order to continue creating a uniform, harmonious skin tone that is comfortable to look at. To clarify, there is an enzyme (biological catalyst) called Tyrosinase Enzyme, which works to “accelerate” the production of melanin pigment in skin pigment cells. The role of vitamin C here is that it inhibits the action of the tyrosinase enzyme. Therefore, when the activity of this enzyme is weakened by vitamin C, the level of skin tan formation decreases, and it is protected from this unhealthy change.
It also protects the skin from hyperpigmentation. Because hyperpigmentation is a problem, and it is a common condition in which dark spots appear on the skin as a result of prolonged exposure to environmental stresses and ultraviolet rays from the sun, especially in important areas of the skin, such as the shoulders, neck, and face. Vitamin C works to neutralize free radicals, thus preventing the formation of dark spots.
