There's a clear link between insomnia and hypertension.
A Japanese study set out to see if they'd reach a similar conclusion. Researchers looked at over 5,000 individuals with an average age of 44.
They found that those with hypertension (also known as high blood pressure) were more likely to suffer from insomnia. Those with insomnia were also more likely to suffer from hypertension.
Unfortunately (and perhaps unsurprisingly), most of the individuals hadn't sought medical advice - most cases of insomnia were going untreated, or were being self-treated with alcohol or over the counter sleeping pills.
