There are many people who like to listen to music while they work and I am certainly one of them. I find it helps me focus more on the task at hand. Of course I can imagine that there are people who listen to music because it helps them NOT to focus on their job.

Whilst there may be many reasons for wishing to listen to music in the workplace, can it really improve your productivity?

We know that music can alter your mood. Films have been using musical scores for years to create the right mood for a scene. At times you hardly notice the music at all but you are very receptive to the mood being conveyed. So can we use music to put us in a “productive” mood?

Research seems to support such a claim. For example, a trial where 75 out of 256 workers at a large retail company were issued with personal stereos to wear at work for four weeks showed a 10% increase in productivity for the headphone wearers. Other similar research conducted by researchers at the University of Illinois found a 6.3% increase when compared with the no music control group.

So if we accept that music does increase productivity, does it matter what types of music we listen to? Does all music have the same effect or are certain types better in certain circumstances?

If your goal is to increase your concentration then music which has a constant, easy beat and light melodies are recommended. These are said to be good for those trying to study as they help you pace your reading to aid focus and memorising. Baroque music is reported as an excellent example, especially the works of Vivaldi, Bach and Handel.

Rock music can have a similar effect. According to a report in the journal Neuroscience of Behavior and Physiology, the Russian Academy of Sciences discovered that a person’s ability to recognize visual images, including letters and numbers, is faster when either rock or classical music is playing in the background.

If you are aiming to be more productive through being more relaxed, then you may be interested to learn that research has shown that music with an upbeat rhythm can reduce stress hormone levels by as much as 41%.

Some of the most publicised studies into whether listening to music increases productivity have centred on what has been termed the “Mozart effect”. The term got its name after a study showed that college students had performed better solving mathematical problems when listening to classical music. The effect of listening to Mozart does not appear to be limited to humans either. Apparently cows will produce more milk if Mozart is played.

If you ask any cat or dog owner, they will tell the animals are one of the family. Talk to them for a while and they will strike you as happy and well-adjusted. This might not seem significant but continuing medical research has detected a significant trend. This is not just your neighbor. It’s the majority of people who keep a pet. The most recent piece of research was presented to the International Society of Anthrozoology conference held in Kansas City this October by a team from Loyola University of Chicago.

They were testing the hypothesis that the use of dogs in a hospital environment would represent a beneficial therapy, promoting faster healing and a better rehabilitation following joint replacement surgery. Some of you will be convinced that dogs are the equivalent of disease carriers and believe they should never be allowed into a hopefully relatively sterile hospital. After all, dogs are barred from most eating places. Allowing animals into public spaces is a balancing of risks and benefits. Hospitals are not as clean as we might believe and dogs do not make what is often a bad situation any worse. In fact, their presence is proving to be great therapy and the benefits of admission now significantly outweigh keeping them out.

The team was using a number of dogs specially trained to respond positively to patients. Each animal has been taught some 40 different commands and will respond with behavior likely to soothe a patient or to motive his or her to resume movement. The exploits a fairly common reaction in humans to stroke dogs. Many of them found the feeling of fingers running on and through fur to be relaxing. When the dogs also appear to show appreciation, bonding takes place quickly and patients feel happier. Pets are stress busters. Even more significantly, this research confirms that patients going through rehabilitation with dogs healed more quickly and used 50% less painkillers than a control group who relied on human therapists for counseling and support. Regular monitoring found the pets lowered the heart rate and blood pressure of their human companions.

It’s easy to sneer at research like this, feeling people who get sappy over dogs are strange in all kinds of ways. Yet this research is not unique. There have been many studies with similar findings. The real point of interest in the latest trial is the finding that patients who are not pet owners benefit after only one period of interaction with a dog. The more regular the contact, the better the human’s physical and emotional response. This research does not, of course, suggest people should recover from serious surgery without the use of some painkillers. Tramadol will remain the standard drug for pain management. But the finding that people recover more quickly using less medication is encouraging. No matter how good tramadol, it’s better to use it only over the short term. Having a pet is clearly a good move.
