Concordia University researchers identify five sleep profiles

Researchers from Concordia University in Montreal have identified five distinct biopsychosocial sleep profiles that influence mood, brain function, and long-term health. The study, published in the journal PLOS Biology, suggests that sleep patterns are shaped by a combination of biological, mental, and environmental factors, including stress and bedroom comfort.

The five identified profiles are:

1. Poor sleep and mental health: Characterized by poor sleep quality and high levels of stress, fear, and anger, with an increased risk of anxiety and depression.

2. Sleep resilience: Individuals who report sleeping well despite having poor mental health or attention issues, suggesting a potential underestimation of sleep problems.

3. Sleep aids and sociability: Those who use aids to fall asleep and report strong social support, but demonstrate lower emotional awareness and weaker memory.

4. Sleep duration and cognition: Individuals sleeping fewer than six to seven hours per night, showing lower problem-solving abilities and higher irritability.

5. Sleep disturbances and mental health: Individuals experiencing frequent awakenings, pain, or temperature issues affecting their mental well-being.
