Having nightmares on a weekly basis seems to accelerate ageing – and could even triple the risk of early death.
“People who have more frequent nightmares age faster and die earlier,” says Abidemi Otaiku at Imperial College London.
Along with his colleagues, Otaiku analysed more than 183,000 adults, aged 26 to 86, who had taken part in several studies. At the start, the adults self-reported how often they had nightmares, and were then tracked for as little as 1.5 years to as long as 19 years.
The researchers found that those who reported having nightmares on a weekly basis were more than three times as likely to die before they turned 70 than those who said they never or rarely had nightmares.Scary dreams disrupt our sleep and elevate our levels of the stress hormone cortisol, which may have serious consequences for our health over time.
