More factors that contribute to muscle cramps

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.

  • Does owning a dog help you live longer?

    A new study has discovered that dog owners:

    • live longer
    • less likely to suffer a heart attack
    The protective effect of having a dog is increased if the dog is a hunting dog e.g. a terrier or a retriever. However it may not be owning a dog itself that helps you live longer but the lifestyle of dog owners.  This is because dog owners have to walk the dog so they are more active.  During these walks they may bump into other dog walkers and talk so there is increased social contact.  In addition the dirt the dog brings into your home changes the dog owners gut microbiome making them less susceptible to a heart attack. What ever the reason the statistics are impressive.  The risk of premature death drops by around 33% and the chances of a heart attack is reduce by 11%, according to researchers who studied the health of 3.4 million swedes of which 13% owned a dog for up to 12 years. To focus in on the benefits of dog ownership, researchers focused in on single people living alone as this is recognised risk for heart disease. One potential flaw in the is study is that people who choose to get a dog may already be more active and social and hence less likely to develop heart disease anyway.
