In middle-aged adults, insomnia and short sleep duration act as mediators linking depression to increased hypertension incidence, suggesting that treating sleep disturbances can reduce cardiovascular risk.

If you are middle-aged and struggling with depression, prioritize treating your sleep problems (insomnia or short sleep duration) as aggressively as you treat your mood. The research indicates that fixing your sleep can significantly lower your risk of developing high blood pressure, which is a major driver of heart disease. This is not just about comfort; it is a cardiovascular protective strategy.
