The habit of using your mobile phone or laptop until late at night comes at a cost. According to recent studies, exposure to screens between 11:00 PM and 1:00 AM can reduce melatonin production by up to 23%. This decrease directly affects the circadian rhythm, altering the quality of rest and, in the long term, the user's health.
The science of misalignment: blue light and circadian rhythm 🌙
Blue light emitted by screens inhibits the production of melatonin, the hormone that regulates sleep. The human eye interprets this light as a daytime signal, which shifts the biological clock. To mitigate this, some devices integrate night modes that filter this wavelength. However, effectiveness is partial if brightness is not reduced and usage time before sleep is not limited.
The developer who doesn't sleep programs better, or not 💻
That romantic idea of programming in the early hours with a cup of coffee is a classic. But it turns out your brain, with 23% less melatonin, works like an overheating server: it makes errors. So, if your code fails tomorrow because of a semicolon, don't blame the compiler. Blame that late-night LoL game that left you sleepless and craving pizza.
