Therapeutic animal stress

Interacting with animals is known to be therapeutic,  particularly in reducing stress.  But do we consider sufficiently the effects this may have on the animals involved?   We might assume that because it is calming for us, then it must be so for the therapeutic animals, but is this so?  New research suggests that it isn't always without stress for the animals involved.

Positive human-animal interaction relates to changes in physiological variables both in humans and other animals, including a reduction of subjective psychological stress (fear, anxiety) and an increase of oxytocin levels in the brain.  It also reduces the 'stress' hormone, cortisol. Indeed, these biological responses have measurable clinical benefits.  Oxytocin has long been implicated in maternal bonding, sexual behaviour and social affiliation behaviours and in promoting a sense of well-being

So far, so good.  We humans often turn to animals for stress relief, companionship, and even therapy.  We know from the intimate relationship we have with our pets, that this brings much joy to our lives. 

New research published in Physiology & Behavior investigated whether guinea pig assisted therapy could actually be a stressful experience for our furry friends. 

Researchers assessed the behaviour of 20 guinea pigs during animal-assisted therapy; in conditions including with and without places to retreat or with other guinea pigs nearby. Researchers found that across all therapy sessions, the guinea pigs reduced their eating behaviours, were more prone to startling and had an increased risk of freezing. Furthermore, the eye temperature of guinea pigs, a proxy indicator of stress, was positively correlated with the time spent being petted.  

The study’s lead author, Sandra Wirth, Vetsuisse Faculty, University of Zurich, says: 

“Our research shows that being involved in animal-assisted therapy can be unpleasant for guinea pigs if not done appropriately. They should be given enough time to adapt to new settings, be given somewhere to retreat and have access to other guinea pigs to reduce the chances of stress.”

Ian Duncan-Smith says he wants to make those on benefits 'better people'!

By any account, the government's austerity strategy is utilitarian. It justifies its approach by the presumed potential ends. It's objective is to cut the deficit, but it has also adopted another objective which is specifically targeted. It seeks to drive people off benefits and 'back to work'.  The two together are toxic to the poorest in society. Those least able to cope are the most affected by the cuts in benefits and the loss of services. It is the coupling of these two strategic aims that make their policies ethically questionable. For, by combining the two, slashing the value of benefits to make budget savings while also changing the benefits system, the highest burden falls on a specific group, those dependent on benefits. For the greater good of the majority, a minority group, those on benefits, are being sacrificed; sacrificed on the altar of austerity. And they are being sacrificed in part so that others may be spared. Utilitarian ethics considers the ba

A time for every purpose

All life moves. Or, more precisely, all life moves purposefully.  This is true even for trees and plants.  Movement is essential for maintaining life.  Animals migrate; plants disperse.  Some form of migration is an ingredient of all life.  For many organisms, it is a key function of reproduction.  We don't reproduce merely to create a new organism, but also to disperse the population - finding new fertile ground, or resources. Reproduction is a form of migration. Reproduction isn't merely to replicate. Reproduction produces change and diversity.  While we may have strong resemblences in families, we also have differences.  Creating a difference is how evolution works.  In this sense, nature is a continuous exploratory process, finding what works best.  Nature senses change and responds.  Some of this is immediate and physiological or behavioural; some of it is over generations.  If we look at a forest over long periods of time, we would see that it shifts. There is a movement

Noise pollution puts nature at risk

 "I just want a bit of peace and quiet!" Let's get away from all the hustle and bustle; the sound of endless traffic on the roads, of the trains on the railway, and the planes in the sky; the incessant drone; the noise. We live in a world of man-made noise; screeching, bellowing, on-and-on in an unmelodious cacophony.  This constant background noise has now become a significant health hazard.   With average background levels of 60 decibels, those who live in cities are often exposed to noise over 85 decibels, enough to cause significant hearing loss over time.  It causes stress, high blood pressure, headache and loss of sleep and poor health and well-being.   In nature, noise has content and significance.  From the roar of the lion, the laughing of a hyena,  communication is essential for life; as the warning of danger, for bonding as a group or a pair, finding a mate, or for establishing a position in a hierarchy - chattering works.  Staying in touch is vital to working
