For thousands of years, humans fell asleep with the only light available after sunset: firelight. Red, warm, soft. This light was the signal that the body learned to read as night — and it began producing melatonin without you having to think about it.
A hundred years ago, the white light bulb arrived. Twenty years ago, screens. Today you go to bed after hours of cold, blue light that your brain still interprets as midday. That's why you can't fall asleep. It's not anxiety. It's biochemistry.
Low-intensity red light does not stimulate the receptors that block melatonin. Your body reads it as what it always was: the last light of the day.
