Does nature restore you? – Part 1
A few years ago now, I moved to London and one of my concerns about moving to London was that I would loose easy access to open green spaces. I have always found that walking through natural green spaces which feel very open have always had a restorative affect on my mental health and general sense of well-being. I know that now I live in London I am very lucky to live within walking distance of Blackheath, so I can still get my “nature top up”. My reaction to nature, made me wonder if their is any scientific evidence of the benefits of nature on health.
A narrative review from Mount Royal University in Canada looked at how contact with nature could help the emotional & mental well-being of cancer survivors. Researches were encouraged by findings that concluded nature could have a positive impact on the well-being of cancer survivors.
Gladwell et al show that lunchtime walks in nature-based environments may provide a greater restorative effect and may improve essential recovery during night-time sleep, potentially enhancing physiological health. While it may be difficult to take a nature-based walk at lunchtime, it is much easier in the summer to take one in the evening.
For those of you that may be thinking, “walking through parks is all very well for you Joanne, but where am I going to find the time for that!”. Please read on…
In 201o researched in the UK looked at evidence from 1,250 people in 10 studies and found fast improvements in mood and self-esteem from green exercise. (Green exercise is defined as activity such as walking, cycling, running, climbing etc in nature). The study found the strongest impact was in young people and just five minutes of green exercises can boost mental health.

Is Reiki a Placebo? – Part 3
While in Part 2 we looked at the impact of healing (Reiki) energy on cells, yeast & animals, that is not the same as on human beings. So in this post I want to share with you some of the research done on humans. So I want to start with looking at physical factors... Krieger (1975) carried out four experiments with the intention of raising blood haemoglobin levels in patients. The technique of Therapeutic Touch (similar to Reiki) was used, with Oscar Estebany being the healer in the first three experiments and nurses trained in the method in the fourth. Significant differences in blood haemoglobin levels were obtained in:
- 43 healed patients as against 33 controls
- 46 healed patients as compared to 33 controls, where the groups were more carefully matched
