Yet another study has found a link between insomnia and heart health.
This time the specific condition is heart failure.
Researchers found that those with insomnia were up to three times more likely to develop heart failure compared to healthy sleepers.
If you include insomniacs with depression and anxiety, the risk of heart failure quadrupled.
This latest study is the largest of its kind conducted to investigate the link between the two conditions.
Researchers followed over 54,000 individuals between 20-89 years of age for over 11 years.
They found that those who experienced all three of the following insomnia symptoms were most at risk:
- Difficulty falling asleep
- Difficulty staying asleep
- Not feeling refreshed and rested upon waking
Although this study found a clear link between heart failure and insomnia, there is still no evidence that sleep deprivation causes heart failure (or vice-versa).
That being said, it's thought that insomnia may trigger stress responses in the body that affect the heart. This makes sense when you consider that over 700 different genes are affected by sleep deprivation.
The best three things you can do?
- Never ignore prolonged insomnia or sleep deprivation.
- Speak to your doctor.
