Dutch researchers have found that the most optimistic participants among a group of 545 men, aged 64 to 84, were 50% less likely to die from cardiovascular causes during a 15 year study.

The men were assessed for their level of optimism every five years from 1985 to 2000, with statements such as “I do not look forward to what lies ahead for me in years to come” or “I am still full of plans.” Higher optimism scores were linked to being younger, being better educated, living with others, having better health, and being more physically active.

A study in Sweden looking at a sample of the population, has concluded that exercise reduces the chance of fracture due to osteoporosis in men.

2205 men, aged 49 to 51, were followed over a 35 year period. Physical activity and other lifestyle habits were recorded at baseline, and at intervals thereafter. Over the 35 years, 428 of the men had at least one fracture, but there were significant differences according to activity levels:
20% of the sedentary men had fractures,
13% of medium activity men (some walking and cycling) had fractures, and
8% of high activity men (sport for at least 3 hours a week) had fractures.

The researchers calculate that one third of fractures could be prevented if men took part in sports more regularly.

A study has found that people who drank tea four times per day for six weeks, had lower blood cortisol levels (a stress marker) and were able to recover more quickly after a stressful event, compared to those who drank a placebo beverage.

Researchers at the University of Nottingham have concluded that eating apples and tomatoes may help prevent respiratory disease.

A total of 2633 adults had their lung function measured in 1991 and again in 2000. Eating more than five apples each week, was associated with increased lung function, as was having tomatoes more than three times per week. Wheezing was also less common among people who consumed apples, tomatoes and bananas.

Taking a siesta in the middle of the day seems to reduce the risk of death from heart disease, particularly in healthy young men. This conclusion on the benefits of a siesta is suggested by a survey of a general population sample of 23 681 people, who at enrolment had no history of heart disease, stroke or cancer. As well as recording napping habits, researchers asked about diet and exercise so as to allow for these additional variables.

It was found that those who occasionally napped, had a 12% lower rate of coronary mortality, whilst those who regularly napped for 30 minutes at least three times per week, had a 37% lower rate. The association was especially strong among men working at the start of the six year study: they showed a 64% reduced risk.
