Associations of ambient air pollution exposure and sleep pattern with brain structures: A prospective study in the UK Biobank.

Summary: Dirty air is bad for your brain. It can actually shrink important parts of it! But there is good news. A large study of over 21,000 people found that getting a good night's sleep can help protect your brain. If you sleep well, it helps block the harm caused by air pollution. So, healthy sleep habits are a great way to keep your brain safe and strong, even if the air outside is bad.
