Here is why I bang on so much about good posture?

My final swap is nettles for spiralina. Spirulina's deep blue-green color reveals its active ingredient — chlorophyll — clearly. Health.com explains it as one of the oldest life forms on Earth and possibly consumed in Aztec and African diets centuries ago. Today it's touted for its ability to strengthen the immune system, reduce fatigue and combat allergies. Nettles are another plant with chlorophyll that even rivals the amount found in spirulina, but they're often found in ditch banks, forests and riverbanks. It's sometimes called "stinging nettle" because it does just that; if you touch it without wearing gloves, the tiny hairs on every surface sting like a bee due to the presence of formic acid, leaving small red welts. But internally, Bon Appetit asserts, it acts like a tonic:

"Taken over time, nettle will strengthen your circulatory, immune, and endocrine systems to promote peak function. The stronger these systems, the better position our bodies are in to deal with whatever might come our way."

"It has been found to help cure mucus congestion, skin irritations, water retention and diarrhea … stimulate the digestive glands of the stomach, intestines, liver, pancreas and gall bladder. Applied externally, nettle tea … relieves rheumatism in both people and animals, makes a first-class gargle for mouth and throat infections, helps to clear up acne and eczema and promotes the healing of burns."

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.

Following on from last weeks blog article on the benefits of garlic in fighting colds and flu, I wanted to share more tips on how to reduce the severity of a cold.

1. Take a zinc supplement: Take zinc lozenges or syrup within 24 hours of the start of a cold, as this may reduce the duration of the cold.  The important thing is to take the zinc within 24 hours.
2. Rest.  You body needs rest to heal.
3. Soothe a sore throat.  I personally like to gargle with sea salt water - 1/2 tea spoon of sea salt dissolved in a large glass of room temperature water. Note: This is in appropriate for children as they may not be able to gargle properly.
4. Sip warm liquids.  This could be chicken soup, team or warm apple juice.  Personally I like a wedge of lemon in hot water with a little chunk of ginger sweetened with manuka honey.
5. Vitamin C.   The scientific jutry is still out on Vitamin C. Personally I dose up with 1000mg of vitamin C throughout my cold.  Taking vitamin C before the onset of cold symptoms may shorten the duration of the symptoms.  Vitamin C may provide benefit for people at high risk of colds due the the frequency of exposure.
6. Echineacea.  Study results on whether echinacea prevents or shortens colds are mixed. Some studies show no benefit. Others show some reduction in the severity and duration of cold symptoms when taken in the early stages of a cold. Different types of echinacea used in different studies may have contributed to the differing results.Echinacea seems to be most effective if you take it when you notice cold symptoms and continue it for seven to 10 days. It appears to be safe for healthy adults, but it can interact with many drugs. Check with your doctor before taking echinacea or any other supplement.
