Being fit is probably very important for mental health, as
well.
Thus, in a huge study from Sweden (over 1 million patient
– all male - records examined) published online in the British Journal
of Psychiatry, the researchers found that "Lower cardiovascular
fitness at age 18 years was associated with increased risk of serious
depression in adulthood” up to 40 years down the road.
Now, clearly it may just be that people less prone to
depression are more likely to be fit (by, for example, engaging in sports,
which is a social activity) than people who are perhaps less outgoing and more
prone to depression.
But whatever that connection between being and depression
may be, the bottom common sense line is that at the very least it can’[t
possibly hurt to be more fit, so if as a parent you can convince your kids to
participate in more sports and less sitting-around activities (the best way is
to participate in sports and other activities yourself, ahem, ahem), then it may do them a lifetime of mental
good.
