Many sources suggest that drinking coffee in the morning disrupts cortisol secretion, a crucial component that helps the body manage stress.

Doctor Hsu Che-lun, an expert in Metabolism and Endocrinology, explained that caffeine temporarily increases cortisol secretion by exciting the sympathetic nervous system. This stimulation affects the hypothalamic-pituitary-adrenal axis (HPA axis), which is the core neuroendocrine system regulating the body's stress response.

Essentially, this mechanism is natural, similar to the alertness reaction you get if you accidentally "spill a cup of coffee on your computer keyboard." These daily physiological reactions will not affect hormone secretion in the long term.

If you are concerned about excessively high cortisol levels, the correct solution is to drink coffee early. The reason is that caffeine elimination is slow, and many people unknowingly suffer from poor sleep quality due to caffeine.

Therefore, if you need to drink mot cup of coffee daily, it is best to start in the morning. Nighttime sleep deprivation is the most damaging factor and has the most severe impact on cortisol levels in the body.

Doctor Hsu Che-lun further pointed out that in daily life, the factors that most often disrupt cortisol secretion are actually medications and topical creams containing steroids.

These drugs disrupt the HPA axis and stimulate cortisol receptors, causing the body to mistakenly believe it has enough cortisol and temporarily stop its own production. When discontinuing or reducing the medication dose, the body faces the risk of adrenal insufficiency.

"Compared to the impact of steroid drugs, drinking mot cup of coffee is truly not a concern," the endocrinologist concluded.
