Can exercise help reduce blood pressure?
High blood pressure is known as the silent killer becuase of its the link to heart attacks and strokes.
The causes of high blood pressure are:
Mental stress: Stress can have a severe impact on blood pressure, especially when it is chronic. It can occur as a result of both socioeconomic and psychosocial factors.
Some aspects of sex: In general, high blood pressure is more common among adult men than adult women. However, after the age of 55 years, a woman’s relative risk of hypertension increases.
A recent study compared the impact of medication and exercise for reducing high systolic blood pressure. The researchers reviewed 197 exercise randomised control trials and 194 randomised control trials looking at medication.
While anti-hypertensive medications achived hight reductions in blood pressure that exercise. Researches concluded that modest but consistent reductions in systolic blood pressure can be achieved with exercise.

How do your friends impact your health?
In my last blog article, I explored how your social network including your friends and family impact your motivation to be healthy. Being part of a group, or better yet, lots of groups is good for your health. The kind of groups doesn't seem to matter - it could be a family group, friendship group, religious or spiritual group, tennis or book club. What is important is that you identify with it and see it as a meaningful part of your life. Here are five good reasons why?
- It can help you live longer
- "As a rule of thumb if you belong to no groups but decide to join one, you cut the risk of dying over the next year in half" R Putman, Bowling Alone.
- An adequate social life provides health benefits on a par with quitting smoking
- The benefits of social ties are akin to those of exercise once you retire. In one study retirees belonging to two social groups had a 2% risk of death but if they lost touch with both groups it jumps to 12%.
- It can protect your heart
- Heart disease is generally lower for those who are members of a social group.
- The risk of death from heart disease diminishes if you belong to more than one social group.
- It can cut your risk of a cold
- Those belonging to a wide range of social groups e.g family friends, work, recreation or religious groups are least likely to come down with a cold. Six or more types of diverse groups cut the risk of a cold more than four times.
- It can alleviate depression
- The more social groups you belong to the less likely you are to suffer from depression.
- If you are depressed, joining a group can help you recover and cut the risk of a relapse by nearly a 1/4 if you join one group or by almost 2/3 if you join three.
- If you are a member of a religious or spiritual group you are less likely to have depressive symptoms and more likely to have feelings of well being.
- It motivates you to be healthy

Reflexology: Scientific Evidence of it’s effects physiological anxiety signs
Recently a scientific study (see details below) was published which evaluated the physiological anxiety signs and sedation needs of patients in intensive care units in a Turkish hospital.
Background It is an accepted medical fact that when it is necessary to mechanically ventilate patients in intensive care units of hospitals, the patients experience stress and anxiety. It is standard medical practice to relieve anxiety, pain, agitation with sedatives to ensure patient comfort. Sedatives however also have side effects causing high blood pressure, slow heart beat, coma, respiratory depression, muscle weakness and atrophy, increased risk of pneumonia, kidney problems and immunosuppression. It may also prolong the need for ventilation which in turn increases the risk of complications. Method 60 patients were split into two groups one of which was the control group. Sedation (Propofol) was reduced 30 min before treatment (or no treatment) which resulted in patients with mixed consciousness to which the outcome measure was administered. This was the American Association of critical care nurses sedation assessment scale (AACNSAS) and the vital signs recorded. Reflexology applied to ears, hands and feet bilaterally was given twice a day for a total of 30 minutes per day, over 5 days. The reflexology focussed on the brain, cortex, hypothalamus, hypophysis and subcortex; areas though to influence anxiety, agitation and stress response. No reflexology was given to the control group but the sedation was reduced and all the same measurements were taken. Results The physiological signs of anxiety and stress i.e. blood pressure, heart rate and respiratory rate were are reduced in the group that received reflexology on each of the 5 days. In addition there was a reduction in the requirement for sedatives in the group that received reflexology. Conclusions These findings ‘show that reflexology is an effective treatment in reducing the physiological signs of anxiety and stress in patients receiving mechanically ventilated support.’ This study provides scientific evidence to underpin the idea that reflexology has a beneficial effect on anxiety and stress.Title: Reflexology: It’s effects on Physiological Anxiety Signs and Sedation Needs Journal: Holistic Nursing Practioner Authors: E.

Natural ways to reduce anxiety – Part 6
My final tip on reducing anxiety is to try chamomile. Chamomile is a herb with a long history of use. A cup of chamomile tea is a common home remedy to calm frayed nerves and promote sleep. A 2009 study showed chamomile may also be a powerful ally against generalized anxiety disorder. The study found people who took German chamomile capsules (220 milligrams up to five times daily) had a greater reduction in scores for tests that measure anxiety symptoms than those who were given a placebo. A more recent trail, much longer term trail reported similar results and noted that the treatment was safe with only a few mild side effects.
