Forests Are Great for Health

1 Hug a Tree for Stress Relief

There may be more to the term "tree hugger" than you think. Dr. Eeva Karjalainen of the Finnish Forest Research Institute in Metla says that "preserving green areas and trees in cities is very important to help people recover from stress, maintain health and cure diseases." She is coordinating a session on the health benefits of forests at the 2010 IUFRO World Forestry Congress in Seoul. Studies have shown that our heart rate, blood pressure, muscle tension and stress hormones decrease more quickly in natural settings like parks or forests. Also, anger and aggressiveness decline when you spend time in natural green environments. Other benefits of nature time include a decline in depression, as well as ADHD symptoms in children.

2 Education Lowers Dementia Risk

Previous research has suggested for each additional year of education, people have an 11 percent lowered risk of developing dementia, but the reason for the association has been unclear. Some theories conclude that the higher socioeconomic status and healthier lifestyles of educated persons is the most likely answer. A team of researchers disagree. Examining the brains of 872 people, the scientists found that more education makes people better able to cope with changes in the brain associated with dementia. The study shows that despite having similar brain pathology, those with more education are better able to compensate for the effects of dementia over those with less. Co-author Dr. Hannah Keage of the University of Cambridge says education in early life is particularly important.

Want Your Eggs Fresh or Frozen?

3 Frozen and Fresh Eggs Have Similar Pregnancy Rates

Eggs fertilized after being removed from the donor or having been frozen six month or longer resulted in a similar pregnancy rates. A study at the Valencia Infertility Institute in Spain looked at over 500 women, who were either implanted with fresh or frozen eggs. All of the women and most of the doctors did not know how the egg was handled before implantation. Two and a half months later, 44 percent and 43 of women who were implanted with frozen and fresh eggs were pregnant, respectively. Eggs can be stored if a donor produces a lot and doctors could test eggs for diseases before implantation. One downside is that eggs would have to be stored in sterile conditions to prevent contamination. There was no follow up on the health of babies born from frozen eggs.
