Anxiety or depression is a significant psychological factor that contributes to insomnia. These mental health conditions can disrupt normal sleep patterns in various ways. Anxiety often leads to racing thoughts and heightened arousal, making it difficult for individuals to relax and fall asleep. It can also cause physiological symptoms such as increased heart rate and restlessness, further hampering the ability to sleep. Similarly, depression can involve changes in sleep architecture and can lead to either insomnia or hypersomnia, depending on the individual. Therefore, addressing these psychological factors is crucial for effective insomnia treatment and management, highlighting the importance of mental health in sleep quality.

Chronic pain, while a valid concern in the context of sleep disturbances, primarily affects sleep through physical discomfort rather than psychological mechanisms. Excessive daylight exposure may disrupt circadian rhythms, yet it does not stem from psychological emotions. Regular exercise before bedtime generally has a positive effect on sleep quality, as it can help reduce stress and promote relaxation, making it less relevant as a factor contributing to insomnia.
