Sharing a bed with someone who suffers from a snoring problem could be bad for your blood pressure, the latest study suggests.
Research on the effect of noise on sleep has found that a snoring partner can increase hypertension by as much as noise from a low-flying aircraft.
A report published in the European Heart Journal found that people's blood pressure levels increased significantly if they experienced a noise louder than 35 decibels - such as aircraft travelling overhead, traffic passing outside, or a partner snoring.
The study, which monitored 140 volunteers, showed that Aircraft noise events caused an average increase in systolic blood pressure of 6.2 mmHg, while average diastolic blood pressure increased by 7.4 mmHg.
"We know that noise from air traffic can be a source of irritation, but our research shows that it can also be damaging for people's health," Lars Jarup, an author of the study from Imperial College London, said.
"This is particularly significant in the light of plans to expand international airports."
He added: "Our studies show night-time aircraft noise can affect blood pressure instantly and increase the risk of hypertension."
Hypertension is linked to a higher risk of heart disease, stroke, kidney disease and dementia.
