I keep an infrared lamp in my office. I turn it on in the morning and enjoy some red light therapy.
It's especially nice In the winter months.
I find the bulbs at the local ranch store in the Spring when they bring in the baby chicks.
The bulb I'm using provides both red and near-infrared light. Both have benefits.
