According to this somewhat light-hearted article, just getting out of bed in the morning may be the worst thing you can do if you‘re trying to avoid a heart attack.
There are a wide variety of events that can trigger an already susceptible heart to go into cardiac failure, including:
- Dehydration
- A bout of anger
- Strenuous exercise
- Infectious diseases, like pneumonia or the flu
Most heart attacks occur first thing in the morning upon waking, as your body releases stress hormones into your bloodstream to prepare your body to get moving. This rise may cause a cardiac event if your arteries are already sufficiently clogged with cholesterol-rich plaque.
