The mood we experience on a daily and weekly basis are influenced by many internal and external factors. Also, our mood can have a significant impact on our overall health.
While fluctuations in mood is part of being human, there are lifestyle strategies that can be put in place to support a healthy mood and therefore overall health and happiness.
When considering internal factors that can influence our mood, remember that all body systems are connected. So if these systems are in balance, our mood is generally humming along nicely, meaning less mood swings, a generally positive outlook and a good stress response. However if they are out of balance, our mood can be negatively affected.
Factors affecting mood
Gut health influences mood by directly communicating with the brain and influencing the synthesis of many of the brain’s messengers (neurotransmitters).1
External factors that can influence our mood include too much stress (physical or mental), excessive environmental noise and pollution, lack of sleep, poor dietary habits and alcohol intake.2-6
Along with reducing exposure to these external factors, there are a number of lifestyle strategies that can be put in place to support a healthy mood.
Key treatment strategies
The saying ‘we are what we eat’ holds true for mood, with links observed between positive mood and a wholefoods-based diet that includes plenty of fresh fruits and vegetables, fish, wholegrains, quality fats, protein and adequate water.2,3,7
Hormones including oestrogen and progesterone also regulate mood, and imbalanced levels have been associated with mood changes.8
Good gut health is an important part of a healthy mood, so including fermented and probiotic foods such as yoghurt, kefir, sauerkraut, kimchi, fresh miso or a good quality probiotic supplement to a wholefoods-based diet can provide extra support.
Ensure you are getting enough of the key mood nutrients including magnesium, selenium, zinc, B-vitamins and omega-3 fatty acids.9-11
Including stress management practices into daily life such as meditation, mindfulness and yoga have also been associated with boosting daily mood,12-15 while spending time in nature has been linked with improvements to mood and happiness.16 A number of meditation and mindfulness apps are now available for download on mobile devices and can fit into even the most busy lifestyle.
Other strategies that help to support a healthy mood include regular exercise and getting adequate sleep.17,18
Including the above diet and lifestyle suggestions into your life can have a positive and long-term impact on your overall mood and sense of wellbeing.
