Stress is a feeling of emotional or physical tension. It can come from any situation or thought that makes us feel frustrated, angry, or nervous. Stress is our body's response to a challenge or demand.
Some manifestations of stress I often experience the feeling of dizziness, slight headaches, and sometimes being easily tired. These manifestations can be attributed to the cortisol hormone, the body's primary stress hormone that increases the body's resistance to stress and increases blood glucose levels in the bloodstream for the brain to function effectively. Cortisol hormones are secreted into the bloodstream by the adrenal cortex stimulated by adrenocorticotropin hormones (ACTH) from the anterior pituitary gland.
Low levels of cortisol hormones in the bloodstream could cause effects like those mentioned above.
