Depression is one of the modern lifestyle diseases. It is often
associated with westernization. Depression mainly come from 2
causes:
“Not knowing your place in society and having too much choice
causes stress.” – Professor Ronald Duman of Yale University
Brain and Depression
New research discover that stress can cause a reduction in size of
up to 15 percent in a brain region called hippocampus (which
produce new brain cells). Amygdala, which controls fear and anxiety
is founded to be enlarged in some depressed patients. Abnormally
small nerve cells are found in Prefrontal Cortex and disturbed
thought patterns.
Dream and Depression
Excessive dreaming used up a lot of energy in the brain and can
disturb sleep patterns, which in turn can lead to depression. We
need deep sleep (slow-wave stage 4 sleep) which is the part that
physically restores us.
Wealth and Depression
Research seems to suggest that once we have lifted ourselves out of
poverty, further rises in income make no difference to our sense of
well-being, maybe even less happy.
Darkness and Depression
Cold dark winter is well known for causing depression. Sunlight and
bright lights can cure depression, but too much of it will excite
our body from having sufficient rest.
