The adrenal glands are a pair of anatomically complex organs with essential roles in the endocrine system of the human body. Primarily, they produce a host of hormones that are needed for the optimal functioning of the body system. Adrenal problems impair the normal functions of these organs.

A normal sleep cycle is a complex process involving numerous biological regulations and coordination impulses from the brain. In the absence of disorders, the sleep cycle starts from the non-rapid eye movement stage and transitions to the rapid-eye-movement stage. Sleep disorders happen when a defect in the normal flow of the cycle occurs and can have a series of biological and psychosocial consequences.

Thyroid problems generally result from impairments of the thyroid gland, causing abnormal secretion rates of thyroid hormone. Common thyroid problems include Hashimoto’s thyroiditis, Grave’s disease, follicular thyroid cancer, silent thyroiditis, postpartum hypothyroidism, and anaplastic thyroid cancers.

The adrenal gland is an important component of the endocrine system, responsible for the production of hormones and neurotransmitters essential for normal biological functions in humans. Adrenal problems can be caused by factors that destroy the glands or hamper its secretory functions (Addison’s or Cushing’s).

The importance of the right quality and quantity of sleep in humans cannot be overemphasized. Sleep affects cognition, social activeness, and psychological health. The normal sleep cycle in humans is divided into rapid eye movement sleep and non-rapid eye movement.

The thyroid gland is an essential organ in the body’s endocrine system, directly responsible for metabolism and organ development. The thyroid hormones are produced in short bursts and distributed to the target organs, where they affect the needed biological function.
