Why Do You Wake Up at 3AM?

Waking up around 3AM is one of the most common sleep complaints among working professionals.

Sleep Cycles and Cortisol

Sleep happens in cycles of roughly ninety minutes. During the second half of the night, the body gradually increases cortisol to prepare for waking. When stress levels are elevated, this signal can arrive too early.

Stress and Cognitive Activation

If the brain is carrying unresolved problems, waking during lighter sleep stages can immediately trigger thinking.

Environmental Factors

Common triggers include:

1. alcohol before bed
2. irregular sleep timing
3. high evening screen exposure
4. late meals

Infrastructure Close

The goal is not to eliminate every night waking. It is to stabilise the conditions that allow the brain to stay asleep through most of the night.
