Why do I wake up after only 4 hours sleep?

Waking up after only four hours of sleep can be due to various factors, including stress, anxiety, or an irregular sleep schedule that disrupts your circadian rhythm. It may also indicate that you are not reaching the deeper stages of sleep necessary for restorative rest. Additionally, lifestyle factors such as caffeine consumption or excessive screen time before bed can impact sleep quality. If this pattern persists, it might be helpful to consult a healthcare professional for further evaluation.
