Rethinking stress…
We all know that a little bit of stress helps motivate us but too much stress is bad for you, or is it? Most people, including me, that write about chronic stress talk about the devastating impact on our mental or physical health. But a recent study has made me rethink how I look at stress.
A study, Does the Perception that Stress Affects Health Matter? The Association with Health and Mortality (Keller et al, 2012) tracked 30000 adults in the USA for 8 years. The researchers asked, “How much stress have you experienced in the past year?” They also asked, “Do you believe that stress is harmful for your health?” Then they waited to see who died by consulting public death records. No surprise, those who had experienced a lot of stress in the past year had a 43 percent increased risk of dying. The big surprise to me, this finding was only true for the people who also believed that stress is harmful for your health. Not only that, people who experienced a lot of stress but did not think it was harmful had the lowest risk of dying, even lower than those who had very little stress. So the belief that stress is harmful to your health seems to be more harmful than the stress itself!
According to Dr Kelly McGonigal (a Stanford University Health Psychologist), this translates to more than 20,000 Americans a year dying not from stress, but from the belief that stress is bad for you, so she urges us to see stress as positive and introduces us to an unsung mechanism for stress reduction: reaching out to others.
We all know the physical response to being under stress, heart pounding, breathing faster, breaking into a sweat. Normally we interpret these physical changes as anxiety or signs that we are not coping very well under pressure. “But what if you viewed them instead as your body was energized, preparing for you to meet this challenge?” A Harvard study, Mind over Matter: Reappraising Arousal Improves Cardiovascular and Cognitive Responses to Stress, (Jamieson et al, 2012) she cited validates this view. In the study, participants were taught to rethink their stress response as helpful (breathing faster, for instance, gets more oxygen to the brain) before they were exposed to a standard stress test (such as doing a math test in public). The participants sailed through the test. Get ready for the significant finding: Ordinarily, when stressed, your heart rate goes up and your blood vessels constrict. Those in the study experienced pounding hearts, but their blood vessels stayed relaxed. According to Dr McGonigal, the response “actually looks a lot like what happens in moments of joy and courage”.
Dr McGonigal states that when oxytocin (you may know this as the cuddle hormone) is released as part of the stress response, our biology is nudging us to seek support instead of bottling everything up. The hormone also benefits the heart (which has oxytocin receptors). Accordingly, when you reach out to others (either to seek help or give support) your stress response becomes healthier and you recover faster. Thus, our stress response has its own secret weapon for resilience, which is human connection.
One more study: Giving to Others and the Association Between Stress and Mortality (Poulin et al, 20013) tracked a thousand people over five years. Predictably, the ones who experienced recent major stressful events (such as financial difficulties) incurred a 30 percent increased risk of dying. But – surprise, surprise – those who spent time caring for others showed absolutely no increase in dying. Thus, says Dr McGonigal:
The harmful effects of stress on your health are not inevitable. How you think and how you act can transform your experience of stress. When you choose to view your stress response as helpful, you create the biology of courage. And when you choose to connect with others under stress, you can create resilience.
This made me think its time to rethink my beliefs around stress, may be its time for you to do the same?
In addition, why not help yourself face life’s challenges by trusting yourself and building a supportive network of friends, family and colleagues around you.

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.

What can help period pain? – Part 2
In part 1, I introduced the topic of period pain. In this blog post, I want to explore the topic from the perspective of functional medicine practitioners who believe that period pains are caused by certain nutritional deficiencies particularly vitamin B, magnesium and essential fatty acids. There is evidence that magnesium can reduce the sensitivity to pain. In one study 21 out of 25 women treated with magnesium for six months saw a reduction in the period pain. In one scientific study over 500 women aged between 12 to 21 with moderate to severe period pain took vitamin B1. 87% were completely cured after 3 months. Just 5% saw no effect at all, while 8% saw their pain reduced. There is also scientific evidence that vitamin B6 may be useful too. Finally, there is scientific evidence that Acupuncture can be a safe and effective treatment for period pain.

Do you have tight hips? – Part 2
I know many of my clients sit at a desk for very long hours which can lead to tight hips. So in this post I want to show you how to stretch them.
How to stretch your hips
Single knee hugging Lying on your back, grab your right knee and pull it toward your chest until you feel a stretch. Hold for 20 seconds. Repeat on the left side. Bilateral knee hugging Lying on your back, grab both knees and pull them toward your chest. Hold for 20 seconds. "Cobra pose" Lie face down on the floor, hands parallel to your shoulders. Straighten your arms, lifting your upper torso off the floor. Your lower back should be arched, with your pelvis making contact with the floor. Hold for 20 seconds, then lower yourself back down Hip flexion with abduction/adduction Lying on your back, bring one knee up toward your chest. Holding your knee with both hands, roll your knee from one side to the other for 20 seconds. Repeat on the other side. External hip rotation Lying on your back, pull your right knee toward your chest. Place your right hand on the knee and your left hand on the ankle. Gently pull your right ankle in the direction of your head. Hold for 30 seconds, then repeat on your left leg. Internal hip rotation Lying face down, bend your knees 90 degrees and let your feet fall outward. Hold for 30 seconds. If after trying these stretches you are still strugling with tight hips why not book a deep tissue massage.
