Nevertheless, there are distinct physical causes to our moods. For example, hunger, low blood sugar levels, and sleep deprivation all cause changes in moods.
Psychological disorders also affect people’s moods. Depression causes a person to feel worthless and to lose interest or pleasure in everyday activities. Bipolar disorder includes the above symptoms alternating or mixed with feelings of inflated self-esteem, distractibility, and restlessness. Anxiety disorder causes generalized feelings of irritability and worry.
