According to the BBC, when an irritant contacts the nasal mucosa, it triggers the trigeminal nerve, which sends a signal to the medulla in the lower brain, resulting in the chest expanding, the lungs filling with air, and then a sneeze being expelled. ^[1] According to the health information website Healthline, a sneeze is medically referred to as sternutation, an involuntary reaction triggered when small particles like dust or pollen irritate the nasal mucosa. ^[2] Optometrist Bert Moritz of the Mayo Clinic Health System in Eau Claire, Wisconsin, told NBC that closing the eyes while sneezing is an involuntary reflex in which the brain sends a muscle message that includes closing the eyes, similar to a deep tendon reflex. ^[3] The article states that a person sneezes approximately 5,000 droplets of mucus and air at speeds of up to 100 miles per hour. ^[4] FoodSafety.gov designates the temperature range of 5-60 °C as the 'danger zone' where bacteria multiply rapidly and recommends that perishable foods not be left out for more than 2 hours, or 1 hour if the ambient temperature exceeds 32 °C. ^[5] Healthline recommends that small amounts of hot food can be placed in the refrigerator immediately, while large quantities such as a big pot of soup may temporarily raise the fridge's internal temperature. ^[6] The article states that cooked meat, poultry, soups, stews, guláš, cooked rice, pasta, and egg/chicken/tuna salads keep for approximately 3-4 days in a refrigerator at 4 °C or below, while hard-boiled eggs last up to 1 week, raw ground meat 1-2 days, raw steaks, chops, and roasts 3-5 days, and fresh fish 1-3 days. ^[7] The FDA recommends using a separate refrigerator thermometer and checking the temperature regularly, and states that an unopened refrigerator keeps food safe for about 4 hours during a power outage. ^[8]
