Poor sleep quality can occur as a result of, for example, restless legs, sleep apnea or major depression. Poor sleep quality is defined as the individual not reaching stage 3 or delta sleep which has restorative properties.

Major depression leads to alterations in the function of the hypothalamic–pituitary–adrenal axis, causing excessive release of cortisol which can lead to poor sleep quality.

Nocturnal polyuria, excessive nighttime urination, can also result in a poor quality of sleep.

Insomnia disrupts more than just your sleep, it can affect your mental health and your physical performance throughout the day. Insomnia can also cause you to wake up in the night, not be able to fall asleep or not be able to stay asleep. People that suffer from chronic illness have a high risk of Insomnia. There is short term and long term insomnia. Short term insomnia can last up to several days. Long term insomnia can be from several months to years. Doing work or staying in bed for activities other than sleeping can confuse the brain into thinking that the bed can be used for other things besides sleep.
