Harvard study: Heat slows down the brain by 13%
As temperatures rise, your brain's processing power declines.
A Harvard study of 44 students has confirmed what each and every one of us who has ever been an adult human has learned: summer heat doesn't help you think.
Half the students lived in a building with air conditioning, and half didn't. They were all asked to take a cognitive assessment test on their phones right after getting up. The students with air conditioning did normally, while the students without air-conditioning, however, had 13.4% worse reaction times and coincidentally performed 13.3% worse on the cognitive tests.
The study was conducted over a 12-day period in the summer of 2016, during which there was a five-day heatwave. What's interesting is the heat continued inside long after the outside heat left. Since many buildings are built to retain heat during the winter, they have a tendency to keep all heat in, meaning that a non-airconditioned building can keep the heatwave going inside for sometimes up to 48 hours after the initial natural one. As someone that lived in a crappy Brooklyn building for a particularly brutal summer, I can attest to it getting up to 87ºF inside at night if you forgot to set the timer on the thermostat.
The study has socioeconomic findings, too: if you're too poor to afford air-conditioning you might fall behind at work or at school. In fact, studies are proving this repeatedly.
America, by and large, has an obsession with A/C... 87% of American homes have A/C. There are currently 1.6 billion A/C units in the world, and that figure is expected to be five times greater by 2050 as climate change takes its toll.
Setting a simple intention and coming prepared can help you — and those around you — win big.
- Setting an intention doesn't have to be complicated, and it can make a great difference when you're hoping for a specific outcome.
- When comedian Pete Holmes is preparing to record an episode of his podcast, "You Made it Weird with Pete Holmes," he takes 15 seconds to check in with himself. This way, he's primed with his own material and can help guests feel safe and comfortable to share theirs, as well.

The Amazon Rainforest is often called "The Planet's Lungs."
- For weeks, fires have been burning in the Amazon rainforest in Brazil, likely started by farmers and ranchers.
- Brazil's president, Jair Bolsonaro, has blamed NGOs for starting the flames, offering no evidence to support the claim.
- There are small steps you can take to help curb deforestation in the Amazon rainforest, which produces about 20 percent of the world's oxygen.
How do we combat the roots of these hateful forces?
- American Psychological Association sees a dubious and weak link between mental illness and mass shootings.
- Center for the study of Hate and Extremism has found preliminary evidence that political discourse is tied to hate crimes.
- Access to guns and violent history is still the number one statistically significant figure that predicts gun violence.
