As a Steelworker you are required to operate sheet-metal tools and to apply basic sheet-metal layout techniques. In many Naval Construction Force (NCF) projects, sheet metal is used to protect the exterior of buildings by using flashing, gutters, and at times, complete sheet-metal roofing systems.
You can use any of the following essential oils by themselves or in a combination in a diffuser to help with headaches or congestion: eucalyptus, ravensara, thyme, rosemary, peppermint, frankincense, or manuka. For more intense therapy, steam inhalation may both help you to decongest and help you fight an infection.
Peppermint is an uplifting and bright essential oil known for its antibacterial, antifungal, anti-inflammatory, pain-relieving and decongestant properties. I find it most useful though when I have a cold or headache. When applied to the chest during a cold, peppermint opens and soothes the lungs. For a headache I apply a small amount, diluted in a carrier oil, to my fingertips and massage into the temples. If peppermint oil is a bit strong for you, you can create a mix with lavender to mellow the cooling effects of the peppermint.
