Why You Wake Up Tired After 8 Hours of Sleep

9. Mental Health Factors

Mental health conditions such as depression and anxiety can significantly impact sleep quality. These conditions can lead to sleep disturbances, including difficulty falling asleep, staying asleep, or waking too early. Even with adequate sleep duration, the quality of sleep may be compromised, resulting in feelings of exhaustion. Addressing mental health concerns through therapy, medication, or lifestyle changes can improve sleep quality and overall well-being, helping you wake up feeling more refreshed.

10. Substance Use

The use of substances such as alcohol, nicotine, and certain medications can interfere with sleep patterns and reduce sleep quality. While alcohol may initially help you fall asleep, it can disrupt sleep cycles and lead to fragmented sleep. Similarly, nicotine and some medications can have stimulating effects that hinder restful sleep. Understanding the impact of these substances on sleep and making necessary adjustments can improve the quality of your sleep, ensuring that your eight hours are truly restorative.
