Mental Health and Cardiovascular Disease Risk: What is the role of physical activity?

Mental health accounts for 20% of the disease burden in the European Area and globally.
· This is put down to stress but Mark Hamer thinks there may be other causes.
§ It is thought to be linked to ageing
There are two available treatment options for mental health:
· Anti-depressant drugs
CBT (Cognitive Behavioural
Depression is linked to heart disease
· There is evidence that tricyclic and other anti-depressants can increase the risk of heart disease by 35%
· There is poor scientific rigour in the drug trials carried out which is why there is much ambiguity
- There is generally a 20% reduction in recurrence of depression treated with anti-depressants.
A slow gait while walking is shown to give a 2.5 times increase in the incidence of depression compared to those who walk with a fast gait.
· This is compounded when age is a factor in the data differentiating between the over 70 and under 70 year old age groups
- Depressed people have a 24% increase in the risk of death generally.
- c-reactive proteins in inflammation leading to cardiovascular problems
- Exercise training can lower and control inflammation
- People ‘more dependant’ on exercise have larger mood disturbances following exercise withdrawal.
- Allegedly mental health is linked to ‘sedentary behaviour’.
- Mark Hamer says that there is data to show that lots of TV watching makes you “more vulnerable to mental health”.
