I use candles a lot. No, not just in workings but as an accent to my office and bedroom space. I love the way
candles add such a warming glow to the room. Plus when you are working and get a little more than stressed you may use these as a focal point and unwind mentally.
I use the candles by Glade. They cost more than some of other scented candles but they work well. They throw off a scent that fills the entire room. Coming up the stairs you can actually smell the fragrance. Unlike others I tried, you know the ones that smell good when you sniff them and the only way you can smell them when they are lit is by practically jumping in the container to do so.
Plus there are so many scents that you are able to change with the day. I know that if I am going to have a particularly stressful work day I choose vanillas as they have a direct calming effect.
Use candles with care. Always blow out when they will be unattended.
