A new study found that dirty air can lead to more strokes and make them deadlier. They looked at 110 studies with over 18 million stroke cases. Breathing in stuff like nitrogen dioxide, carbon monoxide, sulfur dioxide, and ozone makes the risk of having a stroke go up by a lot. For example, if you were around nitrogen dioxide five days before, your stroke risk is nearly 30% higher.
A global study about cancer says that in 2020, 70% of the people who died from cancer could have lived if they avoided things like smoking, drinking too much, being too heavy, or getting certain infections. It’s a big deal, and it was published in The Lancet Global Health journal. There are reports that Chris Pratt drank a ton of water while filming Guardians of the Galaxy. Drinking too much water can actually harm you. It can mess up your body.
A stroke is when something goes wrong in your brain because the blood flow gets messed up suddenly. Some common things that can make a stroke more likely are high blood pressure, smoking, diabetes, high cholesterol, being too heavy, having family members with strokes, and getting older. There are two main types of strokes: one is when a blood clot blocks a blood vessel in the brain, and the other is when a blood vessel in the brain breaks and causes bleeding. The second type is rarer but can be more serious.
To tell if someone is having a stroke, watch for these signs:
- Sudden numbness or weakness on one side of their body, especially in the face, arm, or leg.
- Sudden trouble talking or understanding speech.
- Sudden vision problems in one or both eyes.
- Sudden and severe headache with no clear reason.
- Sudden trouble walking, feeling dizzy, losing balance, or coordination problems.
A study from the University of Jordan found that even short-term exposure to dirty air can increase the risk of stroke. They looked at different kinds of pollution, including tiny particles from cars and factories, and found that people exposed to more pollution had a higher risk of having a stroke.
