Sleep and Memory
In a study that will be published in the December issue of Nature Neuroscience, Harvard Medical School researchers found that people who slept after learning and practicing a new task remembered more about it the next day than people who stayed up all night after learning the same thing. Participants were trained to identify the orientation of three diagonal bars flashed for one-sixtieth of a second on a horizontal-striped computer screen. Half of the participants went to sleep that night. The others were kept awake until the second night of the study. Both groups were allowed to sleep on the second and third nights. On the fourth day, both groups were tested on how proficient they had become at identifying the orientation of the diagonal bars. Those who slept on the first night performed better than they had the first day.
Optimism is Good
How a woman views her life can keep her healthy or put her at risk for health problems. Two new studies that examine the effects of stress on women's health during their reproductive years are reported in the November issue of the American Psychological Association's (APA) journal of Health Psychology. The first study explores how optimism can reduce the chance of delivering low birth weight or pre-term babies for medically high-risk pregnant women. The second study shows that the perception of stress can affect a woman's overall health as much as already known stressors like poverty.
Dietary Supplement Warning
The Food and Drug Administration is warning consumers that such supplements, often marketed as fat burners,
could cause serious health problems. Tiratricol is another name for TRIAC, a powerful thyroid hormone. Using products that contain it can cause symptoms of hyperthyroidism including insomnia, nervousness, sweating and diarrhea. Very high levels of the thyroid hormone can also increase the risk for heart attack or stroke. AP
Here is an interesting web site on safety tips:
Some tips: Keep all hard candy and nuts off low coffee tables or end tables. Almost 3,000 people choke to death every year - most of them children. Nearly two-thirds of the children who die are 3 years old or younger.
Make a place in high cabinets for any medications. Almost 70 percent of poisonings involve children. Of those under 6 years old, 41 percent of poisonings involve pharmaceutical products.
Lock up all silver cleaners and similar household products. Of the poisonings of children, the two top categories involve cosmetics (11.9 percent) and household products (11.4 percent). Plants were involved in 7.7 percent of the cases. Post in an accessible place the numbers of the local poison control center or children's hospital help line. To reduce the risk of electrocution, put plastic inserts or covers on exposed, easy-to-find electrical outlets and move hair dryers and curling irons away from bathtubs and sinks that might be filled with water. Every year, more than 3,000 children under age 10 are treated for electrical shock.

Food before Flight
Having a quick snack and a non-alcoholic drink before boarding a plane can lower your chances of becoming sick (fainting, heart attack etc.) in flight, according to a study presented at the American Heart Association's Scientific Sessions 2000.
Good Laugh-Good Heart.
A team of Maryland medical researchers found that people with heart disease were 40 percent less likely to laugh in humorous situations than those with healthy hearts.
Gap between Pregnancies
Researchers for the Pan American Health Organisation in Uruguay examined the effects of interpregnancy intervals for over 400,000 women in Latin America and the Caribbean and found women with gaps between pregnancies of less than six months or longer than 59 months are at increased risk of complications during pregnancy, finds a study in BMJ.
Guidelines for Pregnancy
Usually it is assumed an average woman is fertile between days 10 and 17 of her menstrual cycle. But researchers at the National Institute of Environmental Health Sciences have demonstrated that only about 30 percent of women actually have their fertile window entirely within that timespan. The researchers found, there is hardly a day in the menstrual cycle during which some women are not potentially fertile, from the data from nearly 700 menstrual cycles of 213 healthy North Carolina women.
Dangers of Sporadic Exercise
According to a study reported at the American Heart Association's Scientific Sessions 2000, people who only exercise irregularly and once in a while have a small but definite increase in their risk of an exercise-related fatal heart attack or cardiac arrest compared to those who work out more regularly. In a 12-year study of thousands of male physicians it was showed that men who exercised at least five times a week had a much lower risk of sudden death - about sevenfold less - than those who only exercised once a week. Sudden cardiac arrest kills an estimated 225,000 Americans each year. There's a good way to prevent cardiac arrest during vigorous exercise- get plenty of regular vigorous exercise.
