In reference to HealthDay News, people who suffer from sleepless nights are at higher chances of developing stroke, especially for the young adults, according to a new, large study conducted in Taiwan.

The expansive study conducted in four years found out that individuals who suffer from insomnia increased their risk of hospitalization with stroke by 54%.

The study found out that for young adults aged between 18 and 34, their chances of developing stroke were eight times higher compared to their peers who got good sleep.

Dr. Demetrius Lopes, director of the Interventional Cerebrovascular Center at Rush University in Chicago, said a lot of attention was paid to high blood pressure, obesity, and tissues related to cholesterol, the known risk factors.

Randomly selected health records for 21,000 people with insomnia and 64,000 individuals without insomnia were compared in the new study in Taiwan. None in the records had previous cases of stroke or sleep apnea.

The results were made public in the May issue of the journal Stroke.

The four-year follow-up found out that 583 insomniacs and 962 non-insomniacs got admitted for a stroke. It’s after giving in to account other factors that the researchers concluded that people with insomnia had an increased risk of stroke compared to the non-insomniacs.

Ya-Wen Hsu, a researcher at Chia Nan University, and team also observed a strong correlation between the severities of insomnia to chances of developing stroke.

Individuals with persistent insomnia had a higher risk of suffering from stroke compared to people with intermittent insomnia, and both groups had higher chances of suffering from stroke compared to those whose insomnia stopped during the research.

Risk factors including diabetes, high cholesterol, and high blood pressure were also prevalent on people with insomnia.

Despite finding a strong link between insomnia and stroke, the study failed to prove cause-and-effect.

Dr. Suzanne Steinbaum, a preventive cardiologist at Lenox Hill Hospital, in New York City, said they have seen people that have sleep issues having other health factors that increase their risk for stroke and that the behavioral issue, insomnia, consists of all the multiple factors associated with it to an increased risk of stroke.

Dr. Mark Urman, an attending cardiologist at the Cedras-Sinai Heart Institute, in Los Angeles said insomnia increased these other risk factors and unhealthy lifestyle increases a person’s risks for stroke causing them to suffer from insomnia.

Urman said sleep deprivation can contribute to other risk factors such as blood glucose levels and high blood pressure which in turn promote further insomnia.

According to Rush University’s Lopes, sound sleep boosts a person’s health and much healing occurs when one is asleep. Also, sleep helps in the proper coordination of blood pressure, hormones management, and stress reduction.

The study deduces that late nights studying and partying could leave the young more prone to stroke.
