The Light Choice: Incandescent or LED?
Why Incandescent Light Is Better Than LED (Even If Everyone Says Otherwise)
LED lights are often seen as a smarter, greener, more efficient option. But just because something is modern doesn’t mean it’s better. Most people don’t realise how much LED light can interfere with the body-especially when it comes to sleep, energy, and long-term health.
💡LED Light Disrupts Your Body’s Natural Rhythm
LEDs give off a high amount of blue light, even the so-called “warm” ones. Blue light tells your brain it’s daytime. This is fine in the morning-but at night, it blocks melatonin, the hormone your body uses to fall asleep.
Sitting under LED lights at night keeps the brain wired, increases cortisol, delays sleep, and lowers sleep quality-even if you think you’ve slept enough hours.
💡Incandescent Light Supports Sleep and Recovery
Incandescent bulbs give off red-rich, low-blue light, closer to firelight or sunset. This type of light helps the body wind down properly in the evening. It doesn’t block melatonin. It actually works with the body’s circadian rhythm, not against it.
Before modern lighting, people lived by natural light and firelight. That’s what the human body is built to expect. Going back to incandescent light in the evening is one of the simplest ways to improve sleep, recovery, and energy the next day.
💡LED Flicker and Hidden Stress
Most LEDs flicker rapidly-even if the flicker isn’t visible to the eye. The nervous system still detects it. For some people, this leads to eyestrain, headaches, or a general feeling of fatigue after long exposure.
That constant flicker and blue spike might not seem like a big deal in one night-but it adds up over weeks, months, and years. It’s another stressor layered onto the system.
💡The “Energy Efficiency” Argument Isn’t the Whole Story
LEDs use fewer watts per lumen, but that doesn’t make them fully efficient. In cooler countries like the UK, incandescent bulbs give off heat that can actually help warm up a space-especially during long winters.
And while LEDs last longer, they’re made with rare earth elements, complex electronics, and create more waste at the end of their life cycle. They’re not as green as they seem.
Real efficiency isn’t just about what saves money on a bill-it’s about what supports human health with the least long-term cost.
💡Modern Convenience vs Biological Reality
Modern life constantly pushes people toward screens, artificial light, and overstimulation. But the body still runs on light signals that evolved over thousands of years. Swapping bright, cold LED light for something warmer and more natural is one way to reduce stress without doing anything extreme.
Even small changes-like using incandescent bulbs in the evening-can help the body relax faster, sleep deeper, and wake up more refreshed.
Final Thought
Just because LED lighting is popular doesn’t mean it’s the best choice. It’s efficient on paper, but not always in practice-especially if it’s disrupting sleep, hormones, and daily energy.
Incandescent light works with the body, not against it. Sometimes the older way isn’t outdated-it’s just right.
