People who unwind with a cup of tea every night may have a lower risk of two common forms of skin cancer, new research suggests.
In a study of nearly 2,200 adults, researchers found that tea drinkers had a lower risk of developing squamous cell or basal cell carcinoma, the two most common forms of skin cancer.
Men and women who had ever been regular tea drinkers -- having one or more cups a day -- were 20 percent to 30 percent less likely to develop the cancers than those who didn't drink tea.
The effect was even stronger among study participants who'd been tea fans for decades, as well as those who regularly had at least two cups a day, according to findings published in the Journal of the American Academy of Dermatology.
However, the findings do not mean it's okay to bake in the sun as long as you have a cup of tea afterward. The researchers found no evidence that tea drinking lowered skin cancer risk in people who'd accumulated painful sunburns in the past.
Nor did the study look at the relationship between tea drinking and malignant melanoma, the least common but most deadly form of skin cancer.
Still, the findings support the theory that tea antioxidants may limit the damage UV radiation inflicts on the skin, according to the study authors, led by Dr. Judy R. Rees of Dartmouth Medical School in Lebanon, New Hampshire.
In particular, a tea antioxidant known as EGCG has been shown to reduce burning on UV-exposed skin.
The current findings are based on interviews with 770 New Hampshire residents with basal cell carcinoma, 696 with squamous cell carcinoma, and 715 cancer-free men and women the same age.
Tea consumption was linked to a lower skin cancer risk, even with factors such as age, skin type and history of severe burns considered. However, tea drinkers who'd suffered multiple painful burns in the past did not have a lower risk of skin cancer.
It's possible, the researchers explain, that the antioxidants in tea are enough to limit skin damage caused by moderate sun exposure, but not the "more extreme" effects of sun exposure, such as cancer-promoting damage to the DNA in skin cells.

Despite more health benefit options available to them than at any time in history, America's Baby Boomers may not be even so healthy as their parents.
The Washington Post reports that as the first wave of Baby Boomers -- a generation of Americans born between 1948 and 1964 -- heads toward retirement, surveys indicate they describe their own health as less than ideal.
As a matter of fact, the Post reports, a major study indicates that Boomers say they have more problems with cholesterol, diabetes, blood pressure and physical exertion than the previous generation born between 1936 and 1941.
"We're seeing some very powerful evidence all pointing to parallel findings," the newspaper quotes Mark Hayward, a sociologist at the University of Texas at Austin, as saying. "The trend seems to be that people are not as healthy as they approach retirement as they were in older generations. It's very disturbing."
One of the primary reasons for the decline in good health, researchers speculate, is that previous generations were much more physically active in their daily routines, the Post reports. The number of Baby Boomers who said they were overweight might be a key to the decline in good health, the newspaper said.

Tai chi, an exercise that features slow martial arts-like movements and meditation, significantly improves the ability of older adults' immune systems to fight the virus -- varicella zoster -- that causes shingles, a new study says.
Shingles is a painful, blistery rash. About one-third of adults over age 60 develop shingles.
The 25-week study, conducted at the University of California, Los Angeles, involved 112 people, ages 59 to 86. The researchers found that Tai chi, by itself, increased immunity against varicella zoster to a level that was comparable to having received the standard vaccine against the virus.
When a person did Tai chi and received the vaccine, the immunity against the virus reached a level normally seen in middle age, said the study, which was published in the April issue of the Journal of the American Geriatrics Society.
The study results confirm that a behavioral intervention such as Tai chi can trigger a positive, virus-specific immune response, said lead author Michael Irwin, professor of psychiatry at the Semel Institute for Neuroscience and Human Behavior at UCLA.
"These are exciting findings, because the positive results of this study also have implications for other infectious diseases, like influenza and pneumonia. Since older adults often show blunted protective responses to vaccines, this study suggests that T'ai chi is an approach that might complement and augment the efficacy of other vaccines, such as influenza," Irwin, who is also director of the UCLA Cousins Center for Psychoneuroimmunology, said in a prepared statement.

Adults who can laugh at life's ups and downs may live longer than those who have trouble cracking a smile, concludes a Norwegian study of about 54,000 people tracked for seven years.
At the start of the study, participants filled out questionnaires on how easily they found humor in everyday life and how important they felt it was to have a humorous perspective, USA Today reported.
People who scored in the highest 25% of humor appreciation were 35% more likely to be alive at the end of seven years than those in the bottom quarter, the study found.
The survival advantage of having a humorous outlook was especially noticeable in a subgroup of 2,015 cancer patients. Those with a healthy sense of humor were about 70%less likely to die than those with a weak sense of humor, USA Today reported.
The study was presented at a meeting of the American Psychosomatic Society.

This jade-colored treat is packed with vitamins, flavor and moisturizing benefits.
Drinking two cups of spearmint tea a day might help treat women with an unsightly condition that causes them to grow excess hair on their face, breasts and stomach, Turkish researchers report.
The tea works by lowering the levels of circulating male hormones in these women, the scientists claim in the current online issue of Phytotherapy Research.
The authors called the findings preliminary.
"There are no recommendations for patients and physicians yet," said Mehmet Numan Tamer, co-author of the study and a professor of endocrinology and metabolism at Suleyman Demirel University in Isparta, Turkey. "This is the first clinical study about the spearmint tea, but further studies are needed to give the practical recommendations to patients."
But other experts feel the findings are far-fetched.
"This is absurd," said Khursheed Navder, an associate professor of nutrition and food science at Hunter College in New York City. "I completely think it is very preliminary, and you need major randomized trials. It's nothing to get thrilled about."
Hirsutism is a condition that can occur in both men and women, but, for obvious reasons, it is more of a cosmetic concern in women. The hair growth is a result of unnaturally high levels of androgens such as testoserone.
According to Tamer, standard therapy includes oral contraceptives to suppress androgens or drugs such as spironolactone, which prevents the body responding to androgens.
Spearmint, which grows naturally near Isparta, has been widely used for indigestion, nausea and vomiting, as well as for the common cold, cough, sinusitis, fever and bronchitis.
"Spearmint has been used as an herb for a long time now," confirmed Navder. "These are all folk remedies."
The Turkish researchers thought that spearmint might be linked with reports of diminished libido in townsmen (presumably because of its effects on androgen levels). In one previous rat study, spearmint reduced testosterone levels.
"Previously, we investigated the effects of [peppermint] and [spearmint] herbal teas on testicular function in an experimental rat model and found that testosterone levels were decreased," Tamer said. "Because we found the anti-androgenic effects of spearmint, we decided to observe the effect of this herbal tea on the androgen levels in hirsute women."
For this study, 21 women with hirsutism drank two cups of herbal spearmint tea for five days at a certain time in their menstrual cycle.
All women showed a decrease in free testosterone (circulating hormone not bound to other molecules) and an increase in several different "female" hormones, including follicle-stimulating hormone and estrogen.
There was no significant decrease in total testosterone levels; it was unclear if there was any change in amount of excess hair growth.
"The next step is to show the effect of spearmint tea on hirsutism scores of the women in a treatment period," Tamer said.
Although the amounts of spearmint used in this study are not generally toxic, the herb can be harmful if taken in larger amounts
Albuquerque, N.M. moved from 13th place last year to be named American's fittest city this year in the March issue of Men's Fitness magazine.
The other top 10 in the nonscientific survey of 50 cities are: Seattle; Colorado Springs; Minneapolis; Tucson, Ariz.; Denver; San Francisco; Baltimore; Portland, Ore.; and Honolulu, the Associated Press reported.
The magazine said this year's top 10 fattest cities are: Las Vegas, Nev.; San Antonio, Texas; Miami; Mesa. Ariz.; Los Angeles; Houston; Dallas; El Paso, Texas; Detroit; and San Jose, Calif.
The survey results are based on various lifestyle factors in each city, including the availability of bikes paths or gyms, commute times, fast food restaurants per capita, amount of television watching, along with federal statistics on obesity-related illnesses and injuries.
Magazine editor Neal Boulton told the AP that the list is published each year "to motivate folks to look at the simple things in their lives they can do to be healthy."

Regular acupressure treatment helps reduce agitated behavior in dementia patients, according to a small study by Taiwanese researchers.
Acupressure involves the application of pressure to certain points of the body.
This study of 20 dementia patients found that 15-minute acupressure sessions given twice a day, five days a week, led to noticeable improvements, including reduced wandering and less verbal and physical aggression.
During the sessions, each of five key pressure points was pressed for two minutes using three to five kilograms of pressure. The sessions lasted for four weeks. After the end of that treatment period, patient agitation levels started to increase again. That suggests that dementia patients require acupressure therapy on an ongoing basis, the researchers said.
The study is published in the February issue of the Journal of Clinical Nursing.
The findings have "important implications for the future care of dementia patients," study co-author Professor Li-Chan Lin, of the Institute of Clinical Nursing at National Yang-Ming University, said in a prepared statement. According to Lin, the study shows that acupressure "provides an effective option that, following training, can be carried out at home or in long-term care facilities."
"Agitated behavior in people with dementia is a major concern for caregivers. It can endanger patients and others, make it necessary for them to be moved from familiar surroundings and demoralize and psychologically distress caregivers," Lin noted.
"It is very important that we find interventions that enable us to provide more effective care for (dementia patients), both in their own home and in long-term care facilities," Lin said.
