Your mood is improved when you have extra stress hormones in the blood. true false

False.

Explanation:

When the brain registers a stress-threatening threat, it triggers the sympathetic nervous system, nerve branches that run alongside the spinal cord. The reaction is increased production of cortisol and adrenaline and norepinephrine by the adrenal glands, heartbeat and breathing accelerate, pressure rises and muscles contract.

These hormones are considered stress hormones and when released reduce the caliber of blood vessels and, in the long run, increase the risk of hypertension, cardiac arrhythmias, physiological problems and cause a bad mood for the individual. So we can say that your mood worsens when you have extra stress hormones in your blood.
