Many of our threats are imaginary. The habits and even obsessions that we develop to keep them away are destructive and undermine our moods constantly.

The regular rhythm and upbeat tunes of military music or marching bands positively affect your mood even if you don't actually 'enjoy' listening to it.

Almost all negative moods are missing one key element - calm. By learning calm, you learn to deal with difficult areas. Calm allows us to achieve what we want, without being overwhelmed by anxiety.

Ignoring a problem does not make it go away. In fact, it can simmer away beneath the surface and lead to poor mood and energy levels, and can also cause your moods to become unstable.

Many physical illnesses are associated with depression and anxiety, including heart disease, high blood pressure, diabetes, Parkinson's disease, stroke, kidney disease, lung disease, dementia and cancer.

Mood reflects the biology of the brain. How you feel is affected by the chemicals in the brain, and these are the same chemicals that form the basis of mood-altering drugs. You may use yoga, meditation, cognitive behaviour therapy (CBT) or exercise to alter your mood, or revert to healthy eating, regular exercise and getting enough sleep.
