What harm can come from excessive sunbathing?

Answer 1

When you sunbathe, you are lying out for the sun's harmful UV rays to hit and tan your skin. This is dangerous because these UV rays can damage skin by burning it, having a higher cancer probability.

Answer 2

We tend to think of a nice tan as something glamorous, healthy and attractive, but actually the process is far from it and is very dangerous. In fact your skin tans in order to protect itself from more skin damage! The sunshine makes people feel good, but the cost of a bronzed body is become steeper and the idea of the healthy tan is slowly evaporating. Here are some of the dangers that could affect you and your children.

sunburn causes the skin to be red, painful, and sometimes swollen. Severe sunburn causes blisters, chills, and fever. Multiple sunburns during the teen years is one of the leading risk factors for skin cancer. Children's skin is thinner and more sensitive than adults' skin, and is thus more vulnerable to the elements. So be cautious about letting your baby or toddler stay out in the sun for as long as a sunscreen's SPF number technically allows.

Scientists have found that sunburn can alter the distribution and function of disease-fighting white blood cells in humans for up to 24 hours after exposure to the sun. Repeated exposure to UV radiation may cause more long-lasting damage to the body's immune system. Mild sunburns can directly suppress the immune functions of human skin where the sunburn occurred, even in people with dark skin.

Cataracts are a form of eye damage, a loss of transparency in the lens, which clouds vision. Left untreated cataracts can rob people of vision. Research has shown that UV radiation increases the likelihood of certain cataracts. Although curable with modern eye surgery, cataracts diminish the eyesight of millions of Americans, and necessitate millions of dollars of eye surgery each year.

Exposure to bright light can also trigger migraines and headaches, for up to 24 hours even.

A less serious heat-related condition is called prickly heat or Miliaria. These tiny red bumps form when sweat glands plug up. The rash usually appears in the folds of a child's neck or on his arms, where sweat and moisture get trapped.

Chronic exposure to the sun causes changes in the skin called actinic, or solar, degeneration. The skin over time becomes thick, wrinkled, and leathery. Since it occurs gradually, often manifesting itself many years after the majority of a person's exposure to the sun, photo-aging is often regarded as an unavoidable condition, a normal part of growing older. With proper protection from UV radiation, however, Photo-aging can be substantially avoided.

Skin cancer is the most rapidly increasing form of cancer in the United States. Recent studies indicate that the incidence of skin cancer is increasing at an alarming rate, with 600,000 new cases of skin cancer reported every year. One in five Americans will develop skin cancer in their lifetime and according to the Skin Cancer Foundation, by the year 2010, more than 1 million new reports of skin cancer could be reported each year, Although skin cancer diagnosed in the early stages has almost a 100% cure rate, sun exposure can cause both acute and chronic injury to the skin.

Basal cell carcinoma arises in a layer of skin (basal layer) beneath the skin's surface. It seldom metastasizes, although it may do so if the cancer invades lymph or blood vessels that can carry cancer cells to distant organs. The major spreading mechanism of basal cell carcinoma is by local invasion of surrounding skin tissue. If left untreated, it may become large and disfiguring. While basal cell carcinoma has traditionally been a cancer associated with older people, it is now seen in more young adults than in the past.

Squamous cell carcinoma develops in the outer layers of the skin. It is capable of metastasizing to other areas of the body if not treated early. It also spreads locally and may cause significant disfigurement.

Melanoma can be hereditary; people with family members who have had melanoma are at a higher risk for melanoma. Previous melanoma and moles will also increase a person's risk of developing the disease. Excessive sun exposure and sunburns increase a person's risk of developing not only melanoma but other skin cancers as well.

Actinic Keratosis (AK), also known as Solar Keratosis, by far the most common pre-cancer, is the result of prolonged exposure to sunlight. It is a small crusty or scaly bump or horn that arises on or beneath the skin surface. Actinic Keratoses can be the first step leading to Squamous Cell Carcinoma. Some studies show that ten percent do advance, and 40-60 percent of SCCS begin as untreated AK's.

Leukoplakia is a disease of the mucous membrane. White patches or plaques develop on the tongue or inside of the mouth, and have the ability to develop into SCC. It is caused by sources of continuous irritation, including smoking or other tobacco use, rough edges on teeth, dentures or filling's. Leukoplakia on the lips is caused mainly by sun damage.

Actinic Cheilitis is a type of actinic Keratosis or Leukoplakia occurring on the lips. It causes them to become dry, cracked, scaly and pale or white. It mainly affects the lower lip, which typically receives more sun exposure than the upper lip.

People are becoming educated in the risks of excessive sun exposure and many are realizing that too much of it will come back to haunt you. While traditional tanning lotion provides little if any sun protection, the alternative, sunless tanning lotion can help you achieve a bronze with no burn.

Answer 3

Over exposure to the sun can cause extremely painful skin damage (sunburn). Skin cancers are also more likely as a result of over exposure to the sun.
