About Babies and Children
For babies and children who will live into the 22nd century, a long and healthy life.
Why They Are More Vulnerable
02
Skin
- Melanin production is not fully developed, and the skin’s protective barrier is thinner.
- As a result, UVA can penetrate deeper into the dermis, causing significantly greater damage than in adults.
03
Eyes
- The lens is clearer and thinner, allowing more UV to pass through to the retina, making it more vulnerable.
- Since the eyes are still developing, UV damage tends to accumulate more easily.
04
Immune System
- The immune system is not fully developed, making it more susceptible to weakening.
- Even short exposure (around 5–15 minutes) to midday UV may suppress immune function, increasing susceptibility to illnesses such as colds.
Long-Term Effects
UV exposure during childhood and adolescence does not show immediate effects. Instead, it significantly increases the risk of developing eye and skin diseases later in life.
The World Health Organization also notes that higher UV exposure during early life increases the risk of:
- Cataracts
- Age-related macular degeneration
- Pterygium
It is estimated that 25–50% of lifetime UV exposure occurs before the age of 18, and the World Health Organization emphasizes the importance of UV protection from an early age
A Similar Structure to the Delayed Effects of Radiation
The effects of UV radiation (UVA/UVB), like radiation exposure, often do not appear immediately.
In many cases, they develop later in adulthood, with cumulative exposure during childhood playing a significant role.
UV exposure during early life, particularly in childhood and adolescence, makes the body more vulnerable to damage and significantly increases the likelihood of developing diseases later in life.
UV-induced DNA damage can remain in the body, and over time, repeated repair errors may accumulate.
These accumulated errors are believed to contribute to conditions such as:
- Cataracts
- Age-related macular degeneration
- Pterygium
For example, UVA can damage the eye lens as well as dermal collagen and elastin in infants and children.
Although these changes are not visible at a young age, they may later appear in adulthood as:
- Cataracts
- Wrinkles and skin sagging
- Skin cancer
Recent studies suggest a connection between UV exposure and:
- Atopic dermatitis
- Sensitive skin conditions
UV radiation may also trigger inflammatory cytokines, contributing to these conditions.
But Light Is Essential — Even Indoors
Stable Sleep Rhythm
For infants and children to maintain a healthy daily rhythm,
exposure to natural light is necessary to reset the body’s internal clock (circadian rhythm).
Emotional Stability
Infants and children are in a critical stage of brain development.
Exposure to bright light helps increase serotonin levels, which play an essential role in long-term emotional stability and a positive mental state.
Visual Development
Especially between the ages of 0 and 3, visual development progresses rapidly.
Adequate light exposure supports the development of:
・Visual function
・Depth perception
・Color recognition
These form the foundation for future learning and concentration.
Therefore, while harmful UV should be blocked, it is important to allow natural sunlight into indoor and in-vehicle environments.
UV-blocking window film is one of the most effective solutions to achieve this balance.
Common Conditions
Skin-Related Conditions
- Actinic keratosis (precancerous lesions)
- Basal cell carcinoma (BCC)
- Squamous cell carcinoma (SCC)
- Malignant melanoma

Initiatives by governments, international organizations, and NPOs/NGOs in each country
🇨🇦
Canada
In Canada, skin cancer is the most common type of cancer, accounting for approximately one-third of all cancer cases, and its incidence continues to rise.
For this reason, the Canadian government, including Health Canada and Environment and Climate Change Canada, states that UV radiation damages the DNA of skin cells and is a major cause of skin cancer.
They also emphasize that infants and children are particularly sensitive to UV exposure and recommend taking extra care to protect them from sunburn.
🇺🇸
United States
In the United States, skin cancer is the most common type of cancer.
The Centers for Disease Control and Prevention (CDC) and other U.S. health authorities state that exposure to sunlight is a primary cause and actively issue warnings.
According to guidelines from the American Cancer Society (ACS), UVA can significantly penetrate glass, and they caution that skin can still be damaged even while indoors.
In 2014, the Office of the Surgeon General issued a formal Call to Action for skin cancer prevention, urging stronger UV protection efforts across education, industry, and communities.
As a result, more than 33 states have implemented some form of restriction on tanning facility use by individuals under the age of 18, who are particularly vulnerable to UV exposure.
🌍
International Organizations and NGOs
Since the early 21st century, international organizations, national governments, local authorities, and NGOs have increasingly raised awareness about the risks of UV exposure, leading to rapid progress in UV protection initiatives.
Although awareness of sunscreen began to emerge in some countries around the 1980s, sun exposure was widely considered beneficial at the time, and comprehensive policy measures were not yet common.
- In recent years, it has become increasingly clear that indoor UVA exposure can contribute to skin and eye diseases, including cancer.
- As a result, efforts to reduce UVA exposure in indoor and in-vehicle environments have expanded.
About Pets
For pets that live 10 to 20 years, helping them stay healthy and active even as they grow older.
Why They Are More Vulnerable
Dogs
Like humans, dogs have relatively sensitive lenses, and after the age of 10, more than half develop progressing cataracts.
As with humans, when vision and other sensory functions decline due to cataracts, stimulation from the external environment decreases, which can significantly increase the risk of cognitive decline.
Dogs are often positioned closer to the ground, making them more exposed to direct sunlight and reflected UV rays from surfaces, which is one of the reasons they are more vulnerable to UV exposure.
In particular, the following breeds are more prone to eye and skin conditions caused by UV exposure
French Bulldog
Retrievers
Border Collies
Poodles
Dachshunds
German Shepherds
Cats
Compared to humans and dogs, cats are relatively less prone to cataracts; however, those with short or light-colored fur have a higher risk of skin cancer.
Cats are also more susceptible to conditions such as SCC affecting sensory areas like the ears and nose. In many cases, this can require surgical removal, which tends to have a greater impact on their daily life compared to humans.
Long-Term Effects
For pets as well, just like in humans, UV exposure during childhood and early life significantly increases the risk of future eye and skin diseases rather than causing immediate effects.
A Similar Structure to the Delayed Effects of Radiation
Similar to the delayed effects of radiation (such as leukemia and cancer), the impact of ultraviolet rays (UVA/UVB) often appears later in life. Early-life exposure accumulates over time and plays a major role in the development of diseases in adulthood.
When UV-induced DNA damage is recorded in the body, repeated repair errors can accumulate. Over time, these errors are believed to contribute to conditions such as skin cancer, cataracts, and glaucoma.
For example, UVA exposure during early stages—when tissues are still vulnerable—can damage the DNA of the lens as well as dermal collagen and elastin. This damage may not be immediately visible, but can later manifest as eye and skin diseases.
But Light Is Essential — Even Indoors
Like humans, dogs and cats benefit from brighter environments, which have been shown to support cognitive function, increase activity levels, and contribute positively to overall health.
Therefore, blocking harmful UV while allowing natural sunlight into indoor spaces, UV-blocking window film is one of the most effective solutions.
Common Conditions
Dogs
● Skin-Related Conditions
- Squamous Cell Carcinoma (SCC)
- Hemangiosarcoma
- Solar dermatitis
- UV-induced granulomas
● Eye-Related Conditions
- Cataracts
- Keratitis / corneal ulcers
- Pterygium-like lesions
- Chronic inflammation → may lead to glaucoma
Cats
● Skin-Related Conditions
- Squamous Cell Carcinoma (commonly on eyelids and other exposed areas)
- Solar dermatitis (can progress to SCC)
● Eye-Related Conditions
- Keratitis
Dogs and cats often cannot express their symptoms clearly, so illnesses can progress without the owner noticing.
Many of these conditions are treatable when detected early. If any of the following symptoms are observed, it is recommended to visit a veterinarian promptly.
At the same time, reducing indoor UV exposure—such as by using UV-blocking window film—is considered one of the most important steps in preventing these conditions in the first place.
Initiatives by governments, veterinary organizations, and NPOs/NGOs in each country
🇬🇧
United Kingdom
In the United Kingdom, due to the frequent cloudy weather, many people are not aware that—unlike UVB—UVA can still reach the ground and penetrate indoors even on rainy or overcast days. As a result, some pet owners say things like, “I never thought my cat could get sunburned,” and awareness efforts continue to be emphasized.
The RSPCA warns that neglecting UV protection can lead to a “season of pain and suffering.” Rebecca Ashman, Chief Veterinary Officer at the RSPCA, states: “Cats can get sunburn just like humans and face the same health risks. They may resist at first, but gradually help them get used to it and gently apply sunscreen, at least during the summer months.”
A white cat named Minnie, rescued at an RSPCA facility in Wales, was found to have precancerous lesions on the tips of her ears and underwent surgical removal. Photos of Minnie after surgery were published in the media and are used to raise awareness—advising owners to seek veterinary care immediately if redness, sores, or scabs appear on the ears or nose.
🏥
Veterinary organizations, NPOs, and NGOs
For pets as well, prevention of UV-related damage has increasingly begun to be addressed in recent years—led by governments, local authorities such as states and municipalities, veterinary organizations, and NPOs/NGOs—similar to initiatives for humans, and these preventive efforts are rapidly spreading.
