Some studies show that a saline solution restores moisture to dry nasal passages and sinuses, and curbs inflammation of mucous membranes. If you use a Neti pot or a small squirt bottle for saline irrigation regularly, it can help to thin mucus, give you less postnasal drip, and cleanse your nasal passages of bacteria. What types can I use? You can buy an over-the-counter saline solution or make one at home. Most over-the-counter saline nasal sprays are isotonic, which means the solution is the same saline concentration as in your body. Hypertonic versions have a higher concentration of salt than whatâs in your body. Both types can help clear mucus. Saline sprays also help keep the cilia in your nose healthy.
We define human factors as: the study of all thefactors that make it easier to do the work in theright way. Another definition of human factors is the study ofthe interrelationship between humans, the toolsand equipment they use in the workplace, and theenvironment in which they work [1]. One can apply Human factors knowledge towherever humans work.
A simple way to view human factors is to think about three aspects: the job, the individual and the organization and how they impact peopleâs health and safety-related behavior.. (Health and Safety Executive, United Kingdom).
