Sleepproblems, from nagging insomnia to full-blown sleep apnea, can fivefold increase your stroke risk, according to a new study. That's quite the brickbat being thrown at the sack, isn't it?
Christine McCarthy, a researcher from University of Galway in Ireland, explained, "More than five of these symptoms can be linked to a five-fold increased stroke risk compared to people without sleep problems." This revelation aligns with previous studies linking poor sleep to high blood pressure and vascular damage, both stroke risk factors.
"Unhealthy sleep can inhibit the body's ability to regulate metabolism, blood pressure, and inflammation, all of which are risk factors for stroke," said Kristen Knutson, an associate professor of neurology and preventive medicine at Northwestern University.
Experts suggest letting go of worries and practicing mindfulness before dozing off could help. So, bring on some zen before hitting the hay!
If sleep apnea is your culprit, it can disrupt the pathways regulating blood clotting factors, exacerbating your stroke risk, explained Phyllis Zee, director of the Center for Circadian and Sleep Medicine at Northwestern University School of Medicine.
Snoring and sleep deprivation are symptoms of untreated sleep apnea, and people who snore have a 91% higher stroke risk and a 2.7 times higher risk than those who don't. Night-time twitching, or periodic limb movement disorder (PLMD), can also be a risk factor, according to the study.
It's crucial to note that this research only indicates a connection between sleep problems and stroke, not causation. "Is poor sleep quality the cause, or is it only associated with a series of other unhealthy habits that increase stroke risk?" asked Andrew Freeman, director of heart and vascular prevention and wellness at National Jewish Health in Denver.
To reduce stroke risk, Freeman suggests adhering to good sleep hygiene, eating healthily, and staying active. Aim for six to eight hours of uninterrupted sleep per night, which could lower the risk of cardiovascular diseases. Regularly exposing oneself to sunlight in the morning and late afternoon can also boost sleep quality. And if you consistently struggle with sleep or have unusual sleep patterns, seek advice from a sleep specialist.
Happy snoozing and preempt that stroke risk!
Enrichment insights: Poor sleep is a risk factor for stroke due to its impact on several health issues, including high blood pressure, diabetes, and obesity. Sleep disorders such as insomnia, narcolepsy, and sleep apnea further contribute to this risk by disrupting normal sleep patterns and contributing to the development of these comorbidities. Delayed or insufficient REM sleep can impact memory consolidation and stress hormone regulation, potentially increasing the risk of stroke indirectly.
