Currently I am experimenting with this too and I uncovered a lot of knowledge but I'm still trying to organize it so I can write it down in a coherent way. But because you asked I can give you some ideas.

So
The body as much as it can generate light it can only do it if it has an excess amount of light or energy. if it's kinda empty it needs to refill and it will absorb energies. If your natural energy recycling process is good and you live around pure or good ambient energies it will happen easily. if the energy around you is bad it takes time but it depends on your ability.

Currently I am starting to realize the "depths" of spirituality. No light without darkness as they say. Now why that is. Well it seems we need "dark" to contain the "Light". But if you do it correctly you will make a perfect solar fusion that makes it look like there is no dark at all. You just have to cleanse your "dark containers" from all the "evil". I had such an enthusiasm to write about this and broke open so many energy pathways but now I arrived to a state where I realized again that I have no idea what I am doing at what is even the next step. The true depths of energy work is fascinating. And while you uncover more and more secrets of the human body you always find something that makes you realize how complicated things are and you are merely in the "beginning".

Whatever
my advice is charge up your body with light or more like let your body absorb light and then you can shine again.
Why do you want to shine anyway? I mean it's cool and energizing I guess?
but do you have a deeper reason to do it?
to me it seems like a pointless energy waste. Are you at least impressing fairies or mundanes with it?

I am not trying to be mean here but in spirituality we need to find out our reasons why we do things because if the "origin motive" of our action is unclear or wrong it can hinder us on the path. Wanting cool psychic powers gets in the way of acquiring cool psychic powers or even worse... The foolish usage of your psychic powers comes with a cost you will only realize when it's almost too late.
