A conspiracy of chronobiologic proportions
The Golden State Warriors just won the NBA championship – that much is true – but we’ve got some news that you didn’t get from ESPN. The kind of news that their “partners” from the NBA didn’t want them to report. Unlike most conspiracy theories, however, this one has some science behind it.

In this case, science in the form of a study published in Frontiers in Physiology says that jet lag had a greater effect on the Boston Celtics than it did on the Warriors.
“Eastward travel – where the destination time is later than the origin time – requires the athlete to shorten their day (known as a phase advance). During phase advance, athletes often struggle to fall asleep at an earlier bedtime, leading to sleep loss and, consequently, potential impaired physiological performance and motivation the next day,” senior author Elise Facer-Childs, PhD, of Monash University, Melbourne, said in written statement.
Dr. Facer-Childs and associates took a very close look at 10 seasons’ worth of NBA games – 11,481 games, to be exact – and found “that eastward (but not westward) jet lag was associated with impaired performance for home (but not away) teams.” The existence of a pro-Western bias against teams that traveled eastward for their home games was clear:
- The chance of winning for eastern teams was reduced by 6.0%.
- They grabbed 1.3 fewer rebounds per game.
- Their field goal percentage was 1.2% lower.
And here’s the final nail in the conspiracy coffin: The NBA knew about the jet lag effect and changed the schedule of the finals in 2014 in a way that makes it worse. Before that, the higher-seeded team got two home games, then the lower-seeded team had three at home, followed by two more at the home of the higher seed. Now it’s a 2-2-1-1-1 arrangement that leads to more travel and, of course, more jet lag.
The study was published during the championship series, so the investigators suggested that the Celtics “might benefit from chronobiology-informed strategies designed to mitigate eastward jet lag symptomatology.”
So there you have it, sports fans/conspiracy theorists: You can’t chase Steph Curry around the court for 48 minutes without the right chronobiology-informed strategy. Everyone knows that.
Being hungry can alter your ‘type’
Fasting and being hungry can be a dangerous mix for becoming “hangry” and irritable, but did you know being hungry can also affect your attraction to other people?

Evidence has shown that being hungry can affect important things such as decision-making, memory, cognition, and function. It might affect decision-making in the sense that those six tacos at Taco Bell might win out over grilled chicken breast and veggies at home, but can hunger make you think that the person you just swiped right on isn’t really your type after all?
We’ll leave that up to Valentina Cazzato of Liverpool (England) John Moores University and associates, whose study involved 44 people, of whom 21 were women in their early 20s. The participants were shown computer-generated images of men and women of different sizes. The same background was used for each picture and all the expressions of the models were neutral. Participants were asked to rate each image on how much they liked it. One study was done on participants who had been fasting for 12 hours, and the second was done on those who had just eaten something.
The subjects generally preferred slim models over more rounded ones, but not after fasting. When they were hungry, they found the round human bodies and faces more attractive. So, yes, it’s definitely possible that hunger can alter your attraction to others.
“Future work might seek to elucidate the relationship between physiological states of hunger and shifts in appreciation of the human bodies and whether this relationship might be mediated by individual traits associated with to beholder’s body adiposity,” said researchers.
