Insomnia Plus Depression Increases Risk of Death
People with insomnia have a ten-fold risk of developing depression, and a risk of dying that is similar to the risk from smoking. However, people with both depression and anxiety have a lower risk.
Researchers at King’s College London compiled data from a survey of over 60,000 people and a comprehensive mortality database.
The reasons for these differences between anxious and non-anxious insomniacs are not clear. Perhaps people who score low on anxiety but are depressed are less likely to get help with physical conditions, or may take more risks, leading to a higher risk of death.
