Happy Friday Everyone!

Here are some interesting Fun and Weird Facts about SALIVA!!

PARENTS HAVE SUPER SPIT! – While dummies keep weepy children from screaming all day long, they’re also crawling with germs, especially when kids drop them on the ground. When most parents see their baby’s dummies lying on the floor, gathering all sorts of killer germs, they simply wash it off under cold water. However, there are a few moms and dads who skip the trip to the sink. Instead, they pick up the pacifier, stick it in their mouths and suck off the dirt. That may sound sick, but article-2744242-06E51DC9000005DC-51_306x465researchers believe dummie-sucking parents inoculate their children against allergies. Studies show that surprisingly, kids with the spit-shined dummies were far less likely to get eczema or asthma.

Researchers believe when parents orally clean dummies, they’re transferring some of their own harmless bacteria into the baby’s mouth. These seasoned microbial vets have seen an infection or two and know how to fight off diseases. When they’re introduced into the baby’s microbiome (basically, the community of microorganisms in our bodies), they whip the immune system into shape like a drill sergeant training green troops. 

 

SALVIA CAN INCREASE SEX DRIVE – Over 90 percent of human cultures practice kissing, and so do animals like pygmy chimpanzees and bonobos. Even foxes lick each other, and elephants stick their trunks in each others’ mouths.This-is-40-Parents-Kissing

Kissing releases dopamine, serotonin, and oxytocin, all of which play roles in stirring up passion. However, men have a secret reason for locking lips. According researchers, men prefer wetter kisses, because their saliva contains trace amounts of testosterone. 

 

SALIVA WORKS IN OUR FAVOUR

  • Salivary flow is lower when we are sitting than when standing, and is lower still when lying down. We make much less saliva when we sleep than when we are awake. This allows bacteria to build up and can cause bad breath in the morning.
  • Salivary output is reduced by 3% to 40% if an individual is blindfolded or in the dark.
  • Physical exercise produces sympathetic stimulation, which can diminish salivation.
  • Estrogen and testosterone increase resting salivary flow.
  • Stress triggers the body’s fight-or-flight response, causing, among other things, a rush of adrenaline, an increased heart rate and salivation. The salivary glands flood the mouth with an enzyme called salivary alpha-amylase (sAA), and this can serve as a marker of stress.
  • Our bodies produce 1 to 2 litres of saliva a day that’s an average of about 10,000 gallons of saliva.
  • Saliva contains an enzyme called salivary amylase or ptyalin, which digests starch into a sugar called maltose. (Maltose is later broken up into glucose molecules in the small intestine
  • Saliva is a thick, colorless and glistening liquid consisting of about 98% to 99% water. Mucus produces the glistening appearance and causes the saliva to have a thicker texture than pure water. Saliva also contains enzymes and other proteins, as well as salts and buffering agents to keep the pH at the correct level.
  • If we chew a starchy food like a piece of bread or a cracker for a long time, it will start to taste sweet as the starch molecules break up into maltose molecules.
  • Saliva also contains chemicals that fight bacteria, including lysozyme, lactoferrin, peroxidase and immunoglobulin A.
  • Sodium bicarbonate in saliva helps to neutralize acids in foods and drinks. These acids can damage tooth enamel. Saliva reduces tooth decay and infection in the mouth by washing away food particles, bacteria and dead cells.
  • Saliva keeps the mouth moist and comfortable and lubricates food so that it’s easy to swallow. The saliva also prevents the swallowed food, or bolus, from damaging the wall of the esophagus.
  • The moisture in the mouth helps us to manipulate the tongue and lips to make speech sounds.
  • Saliva helps us to maintain the correct amount of water in our bodies. When we become dehydrated less saliva is made and the mouth becomes drier. This stimulates us to drink.
