Happiness improves health and lengthens life

02.03.2011
A review of more than 160 studies of human and animal subjects has found “clear and compelling evidence” that – all else being equal – happy people tend to live longer and experience better health than their unhappy peers.

The study, in the journal Applied Psychology: Health and Well-Being, is the most comprehensive review so far of the evidence linking happiness to health outcomes. Its lead author, University of Illinois professor emeritus of psychology Ed Diener, who also is a senior scientist for the Gallup Organization, of Princeton, N.J., analyzed long-term studies of human subjects, experimental human and animal trials, and studies that evaluate the health status of people stressed by natural events.

“We reviewed eight different types of studies,” Diener said. “And the general conclusion from each type of study is that your subjective well-being – that is, feeling positive about your life, not stressed out, not depressed – contributes to both longevity and better health among healthy populations.”

A study that followed nearly 5,000 university students for more than 40 years, for example, found that those who were most pessimistic as students tended to die younger than their peers. An even longer-term study that followed 180 Catholic nuns from early adulthood to old age found that those who wrote positive autobiographies in their early 20s tended to outlive those who wrote more negative accounts of their young lives.

There were a few exceptions, but most of the long-term studies the researchers reviewed found that anxiety, depression, a lack of enjoyment of daily activities and pessimism all are associated with higher rates of disease and a shorter lifespan.

Animal studies also demonstrate a strong link between stress and poor health. Experiments in which animals receive the same care but differ in their stress levels (as a result of an abundance of nest mates in their cages, for example) have found that stressed animals are more susceptible to heart disease, have weaker immune systems and tend to die younger than those living in less crowded conditions.

Laboratory experiments on humans have found that positive moods reduce stress-related hormones, increase immune function and promote the speedy recovery of the heart after exertion. In other studies, marital conflicts and high hostility in married couples were associated with slow wound healing and a poorer immune response.

“I was almost shocked and certainly surprised to see the consistency of the data,” Diener said. “All of these different kinds of studies point to the same conclusion: that health and then longevity in turn are influenced by our mood states.”

While happiness might not by itself prevent or cure disease, the evidence that positive emotions and enjoyment of life contribute to better health and a longer lifespan is stronger than the data linking obesity to reduced longevity, Diener said.

“Happiness is no magic bullet,” he said. “But the evidence is clear and compelling that it changes your odds of getting disease or dying young.”

“Although there are a handful of studies that find opposite effects,” Diener said, “the overwhelming majority of studies support the conclusion that happiness is associated with health and longevity. Current health recommendations focus on four things: avoid obesity, eat right, don’t smoke, and exercise. It may be time to add ‘be happy and avoid chronic anger and depression’ to the list.”

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
