What we have come to know as 'sneezing' is actually technically called 'sternutation'.This happens whenever we get an allergy, an infection or when irritants touch our nasal mucosa. Sneezing is beneficial for our health, as it expels foreign particles from our nasal mucosa.

Types of sneezing

There are many different reasons for which people sneeze. Among these, some of the most common refer to sneezing in the light, due to the fact that the signal through which the pupils are shrunk crosses paths with the signal to sneeze or sneezing when feeling a cold draft.

Sneezing-related reactions

You must have experienced, at least once, general sneezing-related reactions such as closing your eyes while sneezing or sneezing more times in a raw. Now, one thing that might surprise you is that also animals, such as dogs and iguanas sneeze. The purpose is the same as in humans, in order to expel foreign particles from the nasal mucosa.

Fighting the sneeze

While holding in a sneeze is not a god idea, as it can lead to hearing loss or even weaken blood vessels in your brain, there are other ways to stop it. For instance, keeping your house clean of dust or pressing your tongue on the roof of your mouth might prove safer not only for you but also for the people around.


Outbreak terms

  • Endemic is a disease that regularly infects humans, like the flu.
  • Pandemic is a worldwide spread of a new disease. 
  • Epidemic

Public health measures

  • Social distancing is a slew of tactics meant to keep people at a six feet distance from each other to keep droplets from an infected person's nose or mouth from landing on another person.
  • Quarantine is restricting the movement of, or isolating, people who might have been exposed to an infection but who aren't sick.
  • Isolation is separating people with confirmed or probable infections from other healthy people.
  • Lockdown is a term used by public health officials or lawyers to refer to anything from mandatory geographic quarantine to non-mandatory recommendations to shelter in place, to anything in between.
  • Cordon sanitaire is the restriction of movement in and out of a region or city.
  • Shelter in place is an order requesting people to stay at home, except for trips to the grocery store, pharmacies, and other essential errands.

Medical equipment

  • A ventilator is a machine that assists a patient in breathing when they have trouble breathing on their own.
  • PPE (Personal protective equipment), such as masks, gloves, face shields, and other gear that keeps health care workers from catching an infection.
  • A respirator is a face mask that seals around the mouth and filters out particles from the air before they are breathed in.
  • Surgical mask or face mask are loose-fitting masks that don't filter out all the particles but stop a wearer from spreading droplets of contagion when they sneeze or cough.

Basic protective measures

... against the new virus:

  • Wash your hands frequently and thoroughly with soap and water or using alcohol-based hand rub.
  • Maintain social distancing, at least 1 meter (3 feet)...

Coming from dangerous places

Protection measures for persons who are in or have recently visited areas where the new virus spreading:

  • Stay at home. Avoiding contact with others and visits to medical facilities will allow these facilities to operate more effectively and help protect you and others from possible infections.
  • If you develop fever, cough and difficulty breathing, seek medical advice promptly. Calling in advance will allow your health care provider to quickly direct you to the right health facility. This will also help to prevent the possible spread of viruses.

Why We Yawn

Yawning is not due to lack of oxygen in the brain as previously thought, but due to a temperature regulation activity, according to a 2014 study. This helps explain why we yawn less in the winters....

Catching A Yawn

Yawning is contagious, and we catch the yawn even while reading(Yawn!) or watching a video of people yawning. A study conducted has shown a link between catching someone’s yawn and empathy, with the more empathetic people yawning more frequently after seeing someone else yawn.

Stop The Yawn

Deep breathing exercises can help us regulate our yawning. It also helps to exercise regularly, avoiding or limiting caffeine and alcohol, and having a sleeping schedule. Drink plenty of water to keep yourself hydrated and cool, along with fruits and veggies.
