4 Your Health: City parks bring happiness to visitors

There are new recommendations about which women should undergo testing for the breast cancer gene.

The U.S. Preventive Services Task Force says all women with a history of breast or ovarian cancer should be assessed for increased risk of BRCA gene mutations.

Women who have an ancestry associated with BRCA gene mutations should also be assessed.

The results of that risk assessment would then determine whether a woman should proceed to genetic counseling and that would decide if testing is needed.

The recommendations say women with no family history or ancestry associated with BRCA gene mutations should not undergo testing.

Negative impact on health from e-cigarettes 

Using e-cigarettes just one time can have a negative impact on your health.

Researchers from the University of Pennsylvania had 31 non-smoking adults take 16 puffs from an e-cigarette that had tobacco flavoring, but no nicotine.

They also underwent MRI exams before and after vaping.

MRI data showed the single e-cigarette use reduced blood flow in the large artery that supplies blood to the thigh and leg.

The blood vessels in that artery were also impaired.

City parks bring happiness to visitors

If you’re ever feeling blue, try taking a walk in the park.

A new study finds visitors to city parks used happier words and express less negativity on social media than they did before their visit.

The new study also found that joy lasted for hours!

In fact, researchers say the happiness from a park visit was equivalent to the mood spike on Christmas.

The effect was stronger in large, regional parks with extensive tree cover and vegetation.
