He laughed
Can laughter really improve our health?
This, not just a good mechanism to relieve stress, laughter has real physiological effects. When you laugh, your body release endorphins, which reduces the feeling of pain and enhance the emotional well. In addition, studies indicate that good laughter can improve the function of the cardiovascular and blood vessels, enhance the immune system and even increase blood circulation.
An interesting fact: “commercial therapy”, a technique that depends on laughing as a treatment, is used in some hospitals and rehabilitation centers to improve the recovery of patients who suffer from various diseases, so it does not reduce the strength of a good joke!
blue
Why are there almost no blue foods in nature?
A. Although we have fruits like wild grapes, most natural foods lack blue. The mind lies in the development and perception of color. Throughout history, linking “blue” humans with a little appetite – places, mold or food in a state of decomposition. On the other hand, plants give priority dyes such as green, red and yellow, which are more attractive to animals, which helps them break down their seeds.
Interestingly, some studies have found that blue can reduce appetite, so little is used in food and packing restaurants. Perhaps this is why you do not see the blue hamburger in the list, thus the failure of blue and purple cats.
Polyphásic dream
Is it better to sleep in several courses instead of once? I lie between 11 and 12, then I open my eyes as between 4 and 5, I read something, and I scratch the navel and after an hour to two hours, I go back to sleep until 8 or 9, very bad?
A. Most people follow the “single sleep” pattern, as they sleep only once during the night. But some cultures and historical figures practiced “phased urinary sleep”, where comfort is divided into a small nap throughout the day. This can increase productivity and sleep efficiency, allowing you to rest less hours without losing rest quality.
Leonardo Da Vinci and Nicola Tesla and even Winston Churchill with a dream of Polyphase, ensuring that he gave them more time to work. However, experts warn that this method is not perfect for everyone and that deep sleep quality remains the key to health.
Ginger beer
The truth or legend is that ginger knows differently on the plane?
A. Food and drink are usually more soy on a plane, but ginger maintains its fresh and dry flavor, but rather better in the air. This is due to the conditions of the cabin, as low humidity and pressure affect our taste panels, which reduces the perception of some flavors.
A study conducted by Lufthansa in 2010 revealed that the cabin conditions reduce the perception of salt flavors by 30 % and sweets by 20 %. Another study of 2015 indicated that strong noise also reduces the severity of sweet flavors by affecting the face nerve to study the ear. In the case of ginger, passengers report that they know less sweet in the air, but his taste is still sharp and dry, which makes it more fresh. The touch of hot ginger makes it a famous drinking drink, recommended for travel evidence for its unique flavor.
