Happiness lengthens life

05.08.2008
Happiness does not heal, but happiness protects against falling ill. As a result, happy people live longer.

The size of the effect on longevity is comparable to that of smoking or not. This is concluded from an analysis of 30 follow-up studies published in the latest issue of the Journal of Happiness Studies (September 2008).

There have been more reports of happy people living longer, but for long it was unclear whether happiness causes longevity, since it can also be that good health add both to happiness and longevity.

Scientists assess causality using long-term follow-up studies, taking initial health into account. The results of such studies seemed contradictory; several studies found the expected causal effect of happiness on longevity, but other studies found no effect and some observed even earlier death among the happy.

The analysis of 30 follow-up studies showed that the difference is in the people under investigation. Happiness does not lengthen the life of seriously ill people, but it does prolong the life of healthy people. Happiness appears to protect against falling ill. One of the mechanisms behind that effect seems to be that chronic unhappiness causes stress, which on its turn reduces immune response. Another possible mechanism is that happiness adds to the chance of adopting a healthy life style.

An implication of this finding is that public health can also be promoted by policies that aim at greater happiness for a greater number.

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...

Im Focus: New nanomaterial can extract hydrogen fuel from seawater

Hybrid material converts more sunlight and can weather seawater's harsh conditions

It's possible to produce hydrogen to power fuel cells by extracting the gas from seawater, but the electricity required to do it makes the process costly. UCF...

Im Focus: Small collisions make big impact on Mercury's thin atmosphere

Mercury, our smallest planetary neighbor, has very little to call an atmosphere, but it does have a strange weather pattern: morning micro-meteor showers.

Recent modeling along with previously published results from NASA's MESSENGER spacecraft -- short for Mercury Surface, Space Environment, Geochemistry and...
