Shout it out: vocalizing pain helps ease it

Shouting “Ow!” or “Ouch!” can ease the feeling of pain. Researchers from the National University of Singapore, experimenting with pain and pain thresholds, maintain that shouting “Ow!” when in pain can substantially reduce the intensity of the soreness. Hence the act of vocalizing pain is therapeutic (Journal of Pain, January 2015).

Researchers conducted experiments by observing participants plunge their hands into extremely cold water. Some participants were allowed to vocalize what they felt, while others were not (they had to remain silent). Participants were requested to hold their hands in the freezing water for as long as possible.

The results showed that the group of participants that were allowed to vocalize their feelings were able to keep their hands in the cold water for up to three minutes longer than the participants who were silent.

Researchers hypothesized that the muscle movements when vocalizing pain somehow divert or confuse the pain signals from entering or registering in the brain. It was also noted that the word “Ow!” is instinctive from birth across all languages. However the researchers are still unsure exactly why or how vocalizing pain helps ease it. They just know that it does.

The acacia thorn trees of Kenya

There are nearly 800 species of acacia trees in the world, and most don’t have thorns. The famous "whistling thorn tree" and the Umbrella Thorn tree of Kenya are species of acacia that do have thorns, or spines. Giraffes and other herbivores normally eat thorny acacia foliage, but leave the whistling thorn alone. Usually spines are no deterrent to giraffes. Their long tongues are adapted to strip the leaves from the branches despite the thorns. The thorny acacia like dry and hot conditions. The thorns typically occur in pairs and are 5-8 centimetres (2-3 inches) long. Spines can be straight or curved depending on the species.

The Knight in the Panther Skin by Shota Rustaveli (2015 translation): book review

The Knight in the Panther Skin (12th century, this edition 2015) is a recent translation by American poet and author, Lyn Coffin. The author, Shota Rustaveli, is Georgia’s most loved poet. This poem is mammoth, a magnum opus – it is 1,656 verses long, separated by chapters. But readers, don’t give up, because every verse is worth reading. It is akin to 1001 Arabian Knights, Geoffrey Chaucer’s The Canterbury Tales, or Shakespearean poetry. King Rostevan of Arabia has a daughter, Tinatin. She loves the knight Avtandil and he loves her. Verse 368 from Avtandil: ‘The doctor’s could do nothing. A dark twilight on my heart now pressed, I was on fire because of love, but nobody knew or guessed. They blamed my blood. The king decided bleeding my arm would be best; I let it be done to hide the suffering I had not confessed.’ But a knight in panther skin is seen weeping, and subsequently kills the king’s soldiers, sparing the king. Before Tinatin weds Avtandil she r...
