Tai Chi and Chronic Pain

Previously I discussed how dehydration & lack of sodium or potassium may cause muscle cramps.  I now want to explore other nutritional factors. Calcium Calcium plays an essential role in muscle contractions.  Some active people report their problem with cramping disappears when they boost their calcium intake.  This anecdotal evidence is disputed by scientists who state that when dietary deficiencies of of calcium occur, calcium is released from the bones to provide what the body needs for proper muscle contraction.  If you are plagued by muscle cramps, it may be worth trying to increase your intake of dairy or other calcium rich foods to see if it helps. Magnesium Just as muscles need calcium to contract they need magnesium to relax. Roffe et al demonstrated that magnesium helps reduce leg cramps that occur in the middle of the night.

Hot flushes are temporary but recurring feeling of warmth that spreads over the body which often begins in the head and neck region and can be very troublesome. Hot flushes often occur during sleep, producing perspiration known as night sweats. As a result, hot flushes can have a big impact on your quality of life. Hot flushes are one of the most common symptoms women have when they go through the menopause. About 3 out of 4 women going through the menopause (75%) will have hot flushes.  If you've had one, there's no mistaking it: the sudden, intense, hot feeling on your face and upper body, perhaps preceded or accompanied by a rapid heartbeat and sweating, nausea, dizziness, anxiety, headache, weakness, or a feeling of suffocation. Researches recruited 209 women who experienced at least four hot flushes or night sweats every day.  All the patients received up to 20 acupuncture treatments within 6 months.  Nearly half the women saw a 47% reduction in hot flushes or night sweats, while almost 12% reported that their symptoms had stopped almost completely although 4% actually saw an increase in their problems. What is interesting is that most of the women how saw their hot flushes and night sweats decrease started seeing improvements after three sessions.

The standard theory of heart disease states that fatty foods cause the arteries to "clog up" and narrow, which is a major feature of cardiovascular disease.  Researchers have discovered that a lack of sleep seem to have more to do with hardening of the arteries (atherosclerosis) than a fatty diet. Not getting enough sleep on a regular basis can cause a buildup of plaque in the arteries, which causes them to stiffen and eventually close. Researchers at Massachusetts General Hospital now think that hardening of arteries has more to do with a "neuro-immune axis" linking sleep to the cardiovascular system.  Sleep helps regulate the production of inflammatory cells and maintain healthy blood vessels, and so it would follow that lack of sleep has the reverse effect. The researchers demonstrated the effect on a group of laboratory mice.  Although the cholesteral levels of sleep deprived ice remained the same, they developed larger arterial plaques and had double the number of inflammatory cells known to contribute to hardening of arteries.
