Did you know there’s actually a kind of depression which comes along when people don’t get enough exposure to ultraviolet light? They literally start to feel sad and down because they aren’t getting enough sunlight. In this way, we’re a lot more similar to plants than many of us realize or want to admit. While we still won’t be manufacturing our own food through photosynthesis or anything like that, we do need regular sunlight exposure for Vitamin D, and some of us need it a lot more than others. Oh, and the illness is called Seasonal Affective Disorder, by the way. Vitamin D deficiency is the major cause.
That’s kind of an extreme example which has been codified by the medical community, but there are many other instances where lighting, or a lack thereof, can have an effect on the mood of a person. Do you know why turning the lights off when going to sleep is actually a good idea? Well, besides creating a dark environment which is actually conducive to sleep, those periods of darkness where the sun (Or whatever light source) is gone are actually beneficial to the brain in other ways. For one, the darkness boosts production of melatonin, which is an important neurotransmitter when talking about sleep.
Because it helps to regulate sleeping and waking cycles, a lack of melatonin can effectively lead to sleeping too much, or not getting enough sleep, or not getting restful sleep when you do manage to sleep. A melatonin deficiency can lead to depression and its effects just like a lack of Vitamin D can, and the way to deal with both is actually kind of similar. See, you could use LED light bars combined with ultraviolet light to make a kind of sunlamp, or a grow light, which you use for yourself, rather than any plants. You can get most of the hardware for this over at http://lightbarland.com/.
By bathing yourself regularly with ultraviolet light, you can give your body the Vitamin D it needs to keep bones solid and prevent the depression caused by a lack thereof. Getting used to those bright lights can also make the darkness which comes after turning them off even more effective at getting your brain to start producing melatonin. Bright days and dark nights here, that’s what I’m talking about. And it works too, though it might take you some time to work out a good balance between the two if you don’t have professional help.
Light isn’t the only thing which seems to exist on an ambient level while simultaneously having a discernible effect on a person. Music which seems to be the background to many scenes in movies is actually one of the major factors for determining the scene’s mood. Have you ever noticed how loud, cheery music makes you want to dance, or how soft, slow and sad tunes make you get all introspective or reflective? Maybe this doesn’t happen for you, but it does for a majority of people. Lots of things can affect our moods – that’s the point I’m making here.
