Vacations, Vitamin D Cut Next Months Deaths?

Seasonality of mortality: Summer vacation link?

Mortality rates in several Mediterranean countries decline in September, due in part to environmental factors but possibly linked to summer vacations, suggests a new study in CMAJ (Canadian Medical Association Journal) www.cmaj.ca.

The study looked at official statistics for Greece, Cyprus, Italy, France and Spain.

Extreme heat and cold are associated with an increased risk of death.

“We speculate that another factor accounting for the lower mortality observed in September in the Mediterranean countries is the preceding summer vacations,” write Dr.

Human height

Human height varies according to both “nature” and “nurture”. The particular human genome that an individual inherits is a large part of the first variable (nature) and a combination of health and environmental factors present before adulthood (when growth stops) are a major part of the second determinant (”nurture”).

International HapMap Project

The International HapMap Project is an organization whose goal is to develop a haplotype map of the human genome (the HapMap), which will describe the common patterns of human genetic variation.
