What is an expected outcome of poor sleep quality?

Poor sleep quality is closely linked to a variety of negative outcomes, particularly concerning both physical health and cognitive function. When an individual experiences inadequate or disrupted sleep, their body is less able to recover and repair itself, which can lead to issues such as weakened immune response, increased risk for chronic conditions like obesity and heart disease, and hormonal imbalances.

Cognitively, lack of quality sleep impairs memory, attention, and problem-solving abilities, making it harder to concentrate and think clearly. This can ultimately lead to decreased performance in daily activities, including school and work. Therefore, the outcome of poor sleep quality significantly affects both the body's health and the brain's functioning, reinforcing the importance of restorative sleep for overall well-being.
