Apparently, there is something more effective than the rays of sunlight and going outside can give you -- soaking in the presence of God or in a more understandable statement, communing with God / spending time through talking about everything under the sun with your Maker.
There are times that staying at home gives you comfort and peace of mind, but I don't know if you have already noticed this that staying too long inside a place where sunlight cannot reach you will lead into feeling unexplainable tiredness or in my language "nawawalan ng gana sa buhay". I advice that if you ever start feeling that way, go out. In hale the air of outside and soak yourself under the rays of sunlight.
But, as I have mentioned earlier, soaking in the presence of God is more effective. It will definitely lighten your emotion and produce a joyous spirit the moment you spend your time in His presence... appreciating all His glory and faithfulness in your life. He is the real producer of the so-called serotonin.
And if you have doubt with everything I say here, experience it yourself. And I pray that you get to encounter the real Producer of the so-called serotonin and start towards a life where you have a relationship with Him, if you have not yet. Shalom!
