Why do older people wake up at 3 a.m., and what does it really mean for their health and sleep? 🤔😱… See more

One of the main reasons is a decline in melatonin, the hormone that regulates the sleep-wake cycle.

When we’re younger, melatonin levels remain steady through the night, supporting deep and continuous sleep. As we age, production gradually decreases. By the early morning hours, levels may fall low enough to signal the brain that it’s time to wake up.

This means you may not be waking because of stress or noise — your body simply isn’t receiving the same hormonal message to stay asleep.

Small environmental triggers can make this worse, such as:

• Streetlights outside
• Glowing electronic screens
• Illuminated clocks
• Hallway or bathroom lighting
• With age, we tend to become more sensitive to light and subtle disturbances.
