What is one of the risks associated with chronic insomnia?

Chronic insomnia is linked to various health issues, and one significant risk it poses is an increased likelihood of experiencing a stroke. This association can be attributed to several factors. Sleep deprivation affects the body’s ability to regulate stress hormones and blood pressure, both of which are critical in maintaining cardiovascular health. Additionally, chronic insomnia can lead to inflammation and metabolic changes, further increasing the risk of stroke.

In contrast, the other choices suggest benefits or improvements, which are not associated with chronic insomnia. Improved memory and a strengthened immune system are generally functions that benefit from adequate sleep, not from chronic sleep deprivation. Similarly, chronic insomnia does not align with an increase in life expectancy; rather, it often exacerbates health issues that can lead to a shorter lifespan.
