BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Cortisol is a steroid hormone made by your adrenal glands. It helps your body respond to stress, regulate blood sugar, and fight infections. In most people, cortisol levels are highest in the morning when they wake up and lowest around midnight.

Detailed explanation-2: -The rise and fall of this stress hormone is crucial for helping you fall asleep by your target bedtime, stay asleep throughout the night, and wake up in the morning. In the early morning, your body’s cortisol production naturally surges and transitions you into wakefulness.

Detailed explanation-3: -When the levels of cortisol in your blood fall, your hypothalamus releases corticotropin-releasing hormone (CRH), which directs your pituitary gland to produce adrenocorticotropic hormone (ACTH). ACTH then stimulates your adrenal glands to produce and release cortisol.
