Happiness, Health, and Productivity … How They’re Connected


Ever since the first workplace sprang into existence, owners and managers have sought ways to improve worker productivity. While many means to this end have been discovered, perhaps the most effective is basic to all humans – happiness.

Ample research supports the contention that happiness and productivity go hand in hand. Forbes Magazine, for example, reported that in hundreds of studies, happy employees achieved an average of 31% higher productivity and 37% higher sales.

Economists at the University of Warwick recently arrived at a similar conclusion. Conducting extensive research, the team discovered that happiness increased worker productivity by 12%. In contrast, unhappy workers were 10% less productive than their cheerier counterparts.

According to the Warwick research team: “Human happiness has large and positive causal effects on productivity. Positive emotions appear to invigorate human beings.” To which they added: “Financial incentives aren’t enough to make for highly productive employees.”

Smile Your Way to Good Health

Mounting evidence also correlates happiness and positive feelings with optimum health. Our immune system is among the many biological components that benefit from a sunny disposition. For example, as reported in Psychosomatic Medicine, a team of medical researchers exposed 350 healthy adults (ages 10-54) to the common cold. Those who felt the happiest on the day of exposure were the least likely to develop that sneezy, stuffy condition we all dread.

On a separate occasion, the same research team conducted an experiment to determine the relationship between happiness and stress levels. At the experiment’s conclusion, the happiest participants had 23% lower levels of cortisol (stress hormone) than those with the least positive feelings. These two studies, of course, are just two of the many instances in which scientific inquiry has demonstrated a causal relationship between happiness and health.

Clearly, anything that boosts human happiness has far-reaching consequences in the key areas of our lives. But raising happiness levels doesn’t necessarily require intensive effort or complex solutions.

Happy Days and Sleepy Nights

What isn’t well known is the light we use to illuminate our offices and house can affect a person’s mood and their immune system. Think of an LED as concentrated natural lighting, suffusing living environments with the same kind of light waves produced by the sun. As with the sunshine, this light stimulates the production of both serotonin (mood-elevating hormone) and melatonin (sleep-producing hormone). Kept in perfect balance by the advanced engineering of biological LEDs, these waves of light promote bright cheerful daytime moods and restful nighttime sleep. Gone will be the grouchiness of the sleep-deprived, leaving a happier you to face the world. All of which means you could buying fewer cold remedies while setting productivity records at your place of employment. And all because of a bulb.
