The effects of lead exposure on overall health have been well document, but a new study reveals early exposure to pollution can have a detrimental effect on personality. Researchers report those who were born following the decline of environmental lead levels had more mature personalities and were more conscientious and less had lower levels of neuroticism than those born in generation with higher lead levels.
A new study reveals the impact climate played in the evolution of the human brain and body. Studying 300 fossils from the genus Homo found across the globe, researchers found those who lived in colder climates had larger body frames. Larger bodies provided a buffer from colder temperatures. Brain size tended to be larger in those who lived in environments with less vegetation and survived by hunting large animals, a task that involved higher cognitive function.
The neighborhood you live in could have an impact on your brain and cardiovascular health, a new study reports.
Early-life exposure to high levels of air pollution was associated with poor inhibitory control during later childhood and poorer academic performance during adolescence.
Early-life exposure to atmospheric lead was associated with less mature and less healthy personality traits in adults.
Short-term exposure to air pollution, even lower level pollution from charcoal grills or gridlock traffic, can have a negative impact on cognition. However, taking an NSAID medication, such as aspirin, can help minimize the impact.
Prenatal exposure to heavy metals such as cadmium, lead, and arsenic, and increased levels of the mineral manganese, were linked to an increased risk of ADHD and autism spectrum diagnosis in children.
It's not only our genetics and environment that play a role in aging and longevity, it's also the random, tiny changes that arise on the cellular level.
Children who grew up in residential areas surrounded by green space were less likely to be diagnosed with ADHD than those who were raised in areas without access to nature.
Pregnant women exposed to nitrates through household drinking water had, on average, babies that weighed ten grams less than women with no exposure to nitrates in drinking water. High levels of nitrate in tap water can cause infant methemoglobinemia, a fatal condition in newborns.
