The Yerkes-Dodson Law Pt. 2: How to Find Balance in Your Life
Last time, we discussed what the Yerkes-Dodson Law is and how it relates to the brain. Today, we’ll be looking at the implications of low and high arousal levels and detailing how you can utilize the law within your life to achieve the ideal balance for a healthy, happy brain.
Low arousal
The state of low arousal is linked to a lack of stimulation which can lead to limited motivation levels, a feeling of lethargy, and reduced cognitive function. What can this mean in the long term? Well, individuals can experience trouble maintaining attention, and synaptic plasticity and neurogenesis can be stunted, processes that are essential for memory and learning. Low arousal states are also associated with certain anxiety disorders and depression.
High arousal
On the other hand, high arousal states often mean high stress levels, increased cortisol, and overwhelm. This can also affect our ability to process information, impair cognitive function, memory, and decision-making skills. Chronic levels of increased arousal can even cause functional and structural changes in the brain, especially in areas such as the prefrontal cortex, amygdala, and hippocampus. This can lead to an increased risk of developing anxiety, depression, and PTSD.
Just the right amount
Understanding the implications of low and high arousal states can help us to recognize why somewhere in the middle is crucial. Moderate arousal levels are conducive to better brain health, optimal cognitive performance, enhanced focus, better emotional regulation, and problem-solving abilities. So, you might be wondering, how do I achieve this balance? Let’s explore:
Boosting brain health
Physical exercise
Getting moving is a great way to get yourself in the ideal arousal state: it increases the release of neurotransmitters such as dopamine and endorphins. This means more controlled moods and improved cognitive function.
Mindfulness practice
Regular meditation, breathing techniques, relaxation, and yoga are excellent ways to reduce excess stress and promote a feeling of calm that helps to regulate arousal levels.
Getting your zzz’s
We’ve said it before, and we’ll say it again: sleep is key! A lack of sleep can cause states of low or high arousal, negatively affecting cognitive performance.
A balanced lifestyle
In summary, taking care of how you treat your body is the best way to regulate your arousal levels. This includes avoiding excess alcohol and caffeine, maintaining a healthy diet, enjoying regular social interaction and making time for hobbies.
