Menthol "incense" makes me focus more

English: Menthol (Photo credit: Wikipedia)

I really enjoy working in an atmosphere of refreshing cool air.

The best way to do this, is to take some menthol crystals and put them on a piece of hot charcoal.
 


For example shisha coal.

It freshens up the room immediately, and in combination with a cup of coffee this is the perfect wake-up combination!


Disadvantage: if you use too much menthol, the air will sting and it's not so healthy.

Advantage: you can use it in many other ways.

• Put it into a candle, 
• in hot water, 
• use it in the sauna...
