Poor sleep quality is caused by the individual
not reaching stage for sleep which has restorative properties. However, people
who are unable to achieve stage for sleep due to brain damage who still lead
perfectly normal lives.
Poor sleep quality can occur as a result of :
Sleep apnea
Sleep apnea is a condition that occurs when a sleeping person's breathing is interrupted, thus interrupting the normal sleep cycle. With the obstructive form of the condition, some part of the sleeper's respiratory tract loses muscle tone and partially collapses.
People with obstructive sleep apnea often do not remember awakening or having difficulty breathing, but they complain of excessive sleepiness during the day.
Central sleep apnea interrupts the normal breathing stimulus of the central nervous system, and the individual must actually wake up to resume breathing. This form of apnea is often related to a cerebral vascular condition, congestive heart failure, and premature aging.
Major depression.
Major depression leads to alterations in the function of the hypothalamus and pituitary causing excessive release of cortisol which can lead to poor sleep quality.
Nocturnal polyuria
Nocturnal polyuria or excessive nighttime urination can be very disturbing to sleep. Excessive thirst or the use of diuretics can also cause nocturnal polyuria.
Nocturnal polyuria can be nephrogenic ( related to kidney disease ) or it may be due to prostate enlargement or hormonal influences.
Deficiencies in vasopressin, which is either caused by a pituitary problem or by insensitivity of the kidney to the effects of vasopressin, can lead to nocturnal polyuria.
