What advantage is gained by elevating blood sugar and blood pressure in times of stress?

Elevating blood sugar and blood pressure during stress provides the body with a quick source of energy and enhances blood flow to vital organs, preparing it for a "fight or flight" response. Increased blood sugar levels supply immediate fuel for muscles and brain function, while elevated blood pressure ensures that oxygen and nutrients are efficiently delivered throughout the body. This physiological response helps improve survival chances in threatening situations. However, chronic elevation can have negative health consequences.
