There is more and more research that indicates a healthy brain plays an essential role in mental health, including one’s ability to sleep. Research has led to advancements in treating depression, anxiety, bipolar disorder and other psychological illnesses. For instance, researchers are beginning to see that the shapes of certain parts of the brain are different among those who have Bipolar Disorder, for instance, versus those who don’t. Another example is the way that the amygdala functions differently in those that have mental illness. There are four parts of the brain that significant in research and have their influence on mental health.
Two of these four parts of the brain play a significant role in alertness and one’s ability to fall asleep. The thalamus and hypothalamus are small but significant. They regulate important levels of functioning, such as sleep and body temperature. The thalamus is responsible for the messages received by the senses and then delivers it to the cerebral hemispheres for processing. It is also responsible for our experience of consciousness, sleep, and alertness. The hypothalamus regulates temperature, hunger, thirst, and energy cycles.
