Our take: Cardiovascular deaths increase during wintertime at 18 percent, causing scientists to analyze this connection. Chris Kaiser, from ABC News reports on the scientists findings:

"Escaping to a warmer climate might not necessarily keep you from suffering a heart attack in the 'winter months,' researchers found.

An analysis of seasonal deaths in seven regions in the U.S. with very different climates found that all-cause and cardiovascular deaths during December and January remained consistently high across all regions, according to Dr. Bryan Schwartz of the University of New Mexico in Albuquerque and Dr. Robert A. Kloner of Good Samaritan Hospital in Los Angeles."
