Factors That Influence Blood Sugar

Physical activity

Circadian Rhythms

The body’s circadian rhythms, which regulate the sleep-wake cycle, can also affect blood sugar levels. The dawn effecta phenomenon in which blood glucose levels rise in the early morning hours, is caused by a combination of the release of hormones such as cortisol and GH (growth hormone).

Stress

Stress can negatively affect blood sugar levels by increasing levels of stress hormones such as cortisol and adrenaline, which can stimulate glucose production in the liver.
