I've talked a lot on this blog about the tremendously worthwhile gains we can make for our physical health by exercising regularly.  See for example the posts "Does healthy lifestyle really make a difference?" and "Common sense isn't common".  Now the recent national depression guidelines "Updated NICE guidelines on treating depression" and "SIGN guidance on non-pharmaceutical management of depression" underline the importance of exercise for psychological health too.

NICE - the UK National Institute for Health and Clinical Excellence - recently published guidance on "Depression in adults (update)" and on "Depression with a chronic physical health problem".  The "Depression in adults (update)"  replaces guidance originally published in 2004 and amended in 2007.  The 28 page Quick reference guide provides a helpful overview.  Interestingly NICE here use the DSM-IV diagnostic criteria for depression rather than the ICD-10 criteria (used in their earlier publications).  A four step approach is charted - each step is described both by who the intervention is for (e.g.
