To realise the benefits of mindfulness it is important that you turn your mindfulness activities into habits. Habits are easy to do and hard to break because you have created strong neural pathways for them. The more you perform and repeat your mindfulness actions the easier they become, as they become habits.
Repeated studies show that regularly practice of mindfulness actually rewires your brain and has been shown to increase levels of serotonin which is vital to happiness. Regular mindfulness practice also reduces levels of the stress related hormone cortisol which helps reduce anxiety, depression, memory loss and sleep disorders.
You can also think of each session of mindfulness meditation effectively as a dose, the more you practice the better the effects usually are. You can also top up your dosage throughout the day by becoming more aware of the present while you’re performing mundane daily acts, like brushing your teeth, doing the dishes, walking the dog, etc.
