Dr. Amir Khan, a prominent NHS doctor known for his appearances on various TV programs, shares insights about the common experience of waking up at 3am. He addresses this phenomenon on social media, reassuring people that it is usually a natural bodily reaction rather than a cause for concern. Many individuals find themselves suddenly awake in the middle of the night, plagued by thoughts and worries, often questioning their lives during these moments.

According to Dr. Khan, the hours around 2 to 4am coincide with a specific phase in the body's sleep cycle. During this time, the levels of cortisol, a natural stress hormone, begin to rise in preparation for waking up. This process is normal and indicates the body's natural rhythm, reflecting an interplay between sleep cycles and hormonal changes that facilitate waking. It's important for individuals to recognize that such awakenings, while sometimes disconcerting, are a regular aspect of the sleep cycle and not an immediate cause for alarm.

Dr. Khan's explanation sheds light on a widespread issue, as many struggle with sleepless nights and anxious thoughts during the early hours. His insights not only normalize this experience but also provide a degree of comfort to those who may feel isolated in their night-time awakenings. Understanding the biological basis for these disturbances could encourage individuals to approach these wakeful episodes with a new perspective, potentially reducing anxiety surrounding sleep disruptions.
