Multiple studies show citrus consumption raises the risk of skin cancer, possibly due to psoralens in the fruit, which is why 'margarita burn' is a known phenomenon.

As the conversation winds down, Rowan leaves the audience with an unexpected data point: several studies show citrus raises skin cancer risk. The culprit isn't vitamin C but psoralens — naturally occurring compounds in citrus that sensitize skin to UV radiation. The phenomenon is well-documented enough to have its own name: 'margarita burn,' the intensified sunburn experienced after pounding tropical cocktails on vacation. Matt, who has recently planted a lime, lemon, and kumquat tree, takes the news philosophically. Both agree that skin cancer — particularly the common non-melanoma types — is something they're not enormously worried about, especially given the offsetting benefits of sun exposure on all the other major killers.
Multiple studies have linked citrus consumption to elevated skin cancer risk — not because of vitamin C, but because of compounds called psoralens. The effect is so well documented that 'margarita burn,' where people get badly sunburned the day after pounding tropical cocktails, is a recognized phenomenon.
Spencer Greenberg and Jeremy Stevenson analyzed almost 500 self-improvement techniques and found they all reduce to just 12 underlying psychological drivers.
Cold exposure has good short-term alertness benefits but the evidence base for long-term health benefits is much weaker than popularly believed.
In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
A study found that simply scheduling enjoyable activities was as effective as standard cognitive behavioral therapy for depression, leading to its own therapy called behavioral activation.
The 'worry time' technique — deferring all worries to a designated time of day — helps people realize they have more control over worry than they thought and reveals it is less useful than it feels.
A study found that participants told to try to stay awake while in bed fell asleep faster than participants told to try to sleep — illustrating the paradox of direct effort.
Spencer Greenberg reduced his severe social anxiety dramatically in roughly 6 months through a structured exposure therapy hierarchy, culminating in asking strangers for hugs.
