The real link between stress and insomnia

We already know that stress and insomnia are linked (but that's not to say stress is the cause of all cases of insomnia). Now a recent study has emphasized just how prevalent insomnia can become in a population plagued by stress.

The rates of insomnia in the three prefectures hit hardest by the Japanese earthquake of 2011 was found to be five times higher four months after the disaster compared to before.

1,259 men and women aged 20 and over were asked to report on their sleep. On average, insomnia prevalence in Fukushima, Miyagi and Iwate prefectures was found to be 32%. Compare this to the national average of 21.1%.

The insomnia prevalence rate in these three prefectures was 4.8 times higher than that found in a similar study conducted two years prior. Interestingly, the national insomnia rate in Japan also increased - by a factor of 1.8.

We wanted to share these statistics since even though the results may not be all that surprising, it shows just how sensitive your sleep is to stress.
