Why does insomnia at 55 get worse again after stress or illness?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

My sleep was finally stable for a while, but after a bad case of the flu and several months of stress, it completely fell apart again. I now have trouble falling asleep, wake up too early, and feel anxious around bedtime.

  1. Why does insomnia at 55 get worse again after an illness or a period of high stress?

  2. Can the nervous system become retrained into a state of hyperarousal after setbacks?

It is exhausting to feel like I am starting from zero again after making progress. Medications help in the short term, but they eventually stop working.

I am scared that each relapse makes my insomnia more permanent. I need to know if recovery is still possible or if this is simply how it goes now.

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

Insomnia (a sleep disorder in which the person may have difficulty falling asleep) often gets worse again after an illness or long periods of stress because the brain and nervous system can become stuck in a state of alertness called hyperarousal.

After a bad flu, emotional stress, or months of worry, the body may stay tense and watchful at night, making it harder to fall asleep or stay asleep.

This does not mean your sleep system is permanently damaged. At 55, sleep naturally becomes lighter and more sensitive to stress, pain, hormones, medications, or schedule changes.

A relapse after progress is very common in chronic insomnia and does not mean you are back at the beginning. The brain can relearn healthy sleep patterns.

Many people develop anxiety around bedtime after several bad nights. The more you worry about sleep, the more alert the brain becomes, creating a cycle of poor sleep and fear of not sleeping. This is why sleeping pills may help in the short term, but sometimes stop working over time.

Recovery is still possible, even after repeated setbacks. Treatments like cognitive behavioral therapy for insomnia (CBT-I, a therapy to improve sleep) are designed to calm the nervous system and rebuild normal sleep habits.

Helpful steps include keeping a regular wake-up time, getting morning sunlight, avoiding spending too much time lying awake in bed, and managing stress, anxiety, pain, or other medical problems that may worsen sleep.

If your symptoms include loud snoring, choking during sleep, or severe daytime tiredness, it may also help to check for obstructive sleep apnea or other sleep conditions.

Most importantly, insomnia relapses do not make the condition permanent. The body still knows how to sleep, and improvement can happen again with time and proper treatment.

I hope I have answered your question.

Let me know if I can assist you further.

Thank you.
