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.

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.

The quickest and easiest way to improve your health and mood is by taking omega 3 supplements, in the form of fish oils or flaxseed. Add a good general multivitamin and mineral daily as well, as this will ensure that any trace deficiencies causing health or mood problems are addressed.

Postural exercises such as yoga, Pilates, Egoscues, Alexander technique and martial arts are about avoiding pain and injury as much as helping you feel good. Attractive men and women have good posture.

Uncertainty causes more anxiety than perhaps any other single factor.

All moods have a cause. If you change the root cause, then your mood will follow suit. Furthermore, mood is a choice. It may not be a completely free choice, but you can choose which mood you spend the most time in.
