Q. How to regularize sleep in a woman who has unusual sleep pattern?

Hi doctor,

My mother has trouble sleeping. Diabetes runs in my family. My grandmother passed away 12 years ago. My father spent a lot of money on her treatment during that period, but unfortunately, she passed away. Due to this, my father was in shock. Also, he had diabetes and passed away 11 years back. My mother was in her mid-forties when my father passed away. Now she has 50 crossed years. The problem with my mother is that she has been suffering from sleeping disorders for the past four years. She is not able to sleep at night. However, if we talk about her medical conditions, she is fit and fine. She wakes up daily at 5:00 AM, goes for a walk, and then she engages in daily activities. Her blood pressure is normal, and she does not have diabetes or cardiac problems.

The other fact is that if I do not sleep at night, the next day, I will have headaches the whole day, which I think most individuals encounter. But surprisingly, my mother did not encounter any problems, and she was fine all day. Also, she is not sleeping during the daytime, and at night we usually go to bed at 10:00 PM, but she sleeps around 2:00 AM daily. So I think she can have health problems in the future because of her unusual sleeping habits. What to do?

Kindly give your suggestions.
