Temporary tattoos trigger skin problems

Want a tattoo to impress your friends but worry about the pain of real ink? Do not fall for temporary tattoos as these may cause allergic reactions to skin.

Allergic reactions to press-on temporary tattoos can involve rashes and blisters while long-term effects might include scarring, skin changes and increased sensitivity to sun, a US Food and Drug Administration (FDA) report has warned.

"If you had a reaction to a temporary tattoo or any cosmetic product, the FDA wants to know," said Katherine Hollinger, an epidemiologist with the FDA office of cosmetics and colours.

Beyond the wet-and-press tattoos found in bubble gum machines, there are several types of temporary tattoos that use plant-based and synthetic dyes.

Some uses henna, mixed with a hair-dye ingredient p-phenylenediamine (PPD), that is not approved by the FDA for use on the skin, the agency noted.

Another dye jagua, derives from the unripened fruit of the Genipa americana, is also not recommended for use.

Real tattoos too come with their own set of risks, including contaminated ink that has caused infection outbreaks, the report added.

Too much exercise dangerous for heart patients

A new research has found that too much exercise may increase the risk of death from heart attack or stroke in patients with existing heart problems.

The new study tracked a decade's worth of exercise habits and survival of more than 1,000 people with diagnosed -- but stable -- coronary artery disease.

The majority of the study's participants were in their 60s and had attended a cardiac rehabilitation program to avoid future heart attacks or strokes.

Around 40 percent of the study participants did an hour of moderate-intensity aerobic activity 2 to 4 times per week; of the remaining 60 percent, half exercised at that level more than four times a week and the other half exercised less. Overall, 1 in 10 said they rarely or never exercised.

The researchers found those who were most sedentary were around twice as likely to have a heart attack or stroke as those who were regularly physically active, CBS News reported.

They were around four times as likely to die of cardiovascular events and all other causes.

But more surprisingly, those who did the most strenuous daily exercise were also more likely to die of a heart attack or stroke than people who engaged in more moderate activity.

The study is published in the journal Heart.
