Vitamin D, Sleep Apnea & CPR

Posted: Updated:

New research finds Vitamin D supplements can protect bones - but not as well as first thought.

The New England journal of medicine study found seniors who took the pills had a 10% lower risk of hip fracture.

And those who took a high dose had a 30% lower risk.

The study authors say the results show vitamin D supplements are only "somewhat favorable" at preventing fractures.

Sleep apnea appears to be worse during the winter months.

Brazilian researchers tracked thousands of people who were tested at a sleep clinic.

During the winter patients stopped breathing in their sleep an average of 18 times per hour - compared to 15 times an hour during the summer.

Japanese researchers looked at 5,000 cases where people had a heart attack in public.

They found the odds of surviving were two fold higher when more than one bystander tried to help.

The American Heart Association says more than 380,000 Americans go into cardiac arrest outside of a hospital every year.
