INSOMNIA MAY TRIGGER CARDIOVASCULAR DISEASE
A new study published in the journal Sleep has found that people who suffer from insomnia have heightened nighttime blood pressure, which can lead to cardiac problems. The investigation measured the 24-hour blood pressure of 13 insomniacs compared to 13 sound sleepers. Subjects spent 40 hours in the sleep laboratory: two nights for adaptation and one for monitoring followed by the intervening day.
“Over many years, chronic insomnia can have negative effects on the hearts of otherwise healthy individuals,” says lead author Paola A. Lanfranchi. “Whereas blood pressure decreases in regular sleepers and gives their heart a rest, insomnia provokes higher nighttime blood pressure that can cause long-term cardiovascular risks and damage the heart.”
“Blood pressure cycles are mainly linked to the sleep-wake cycle,” adds co-author Jacques Montplaisir. “Since blood pressure is heightened among insomniacs, those with overt cardiac disease are particularly at risk for progression of the disease."
