20 Minute Contact with Nature Reduces Stress Hormone Cortisol

 

 

 

 

 

The data revealed that just a twenty-minute nature experience was enough to significantly reduce cortisol levels. But if you spent a little more time immersed in a nature experience, 20 to 30 minutes sitting or walking, cortisol levels dropped at their greatest rate. After that, additional de-stressing benefits continue to add up but at a slower rate. The image is in the public domain.

Los abrazos activan la química cerebral del bienestar, la calma y la alegría, a corto y largo plazo

Los niños “tocan base” cuando están corriendo alegremente y, de repente, se sientan en el regazo de mamá o de papá, se apoyan en ellos o buscan algún tipo de contacto. Esta actitud puede durar segundos, o apenas unos minutos. Enseguida vuelven a sus juegos. Esto se llama “reabastecimiento emocional” y sirve para crear un precioso equilibrio químico en sus cerebros. Si tu hija o hijo se comporta así contigo, te hace un gran cumplido: te considera una fuente natural de opioides cerebrales.

Tanto nuestro cuerpo como nuestro cerebro secretan hormonas, poderosas sustancias químicas que nos pueden hacer sentir muy bien o muy mal. Normalmente, pensamos en las hormonas solo en relación con nuestra sexualidad, pero existen muchos tipos que nos afectan de muchas maneras en nuestros sentimientos, percepciones y comportamientos.

Physicist suggests ‘quantum foam’ may explain away huge cosmic energy

 

Steven Carlip, a physicist at the University of California, has come up with a theory to explain why empty space seems to be filled with a huge amount of energy—it may be hidden by effects that are canceling it out at the Planck scale. He has published a paper describing his new theory in the journal Physical Review Letters.

Conventional theory suggests that should be filled with a huge amount of energy—perhaps as much as 10120 more than seemingly exists. Over the years, many theorists have suggested ideas on why this may be—most have tried the obvious approach, trying to figure out a way to make the energy go away. But none have been successful. In this new effort, Carlip suggests that maybe all that energy really is there, but it does not have any ties to the expansion of the universe because its effects are being canceled out by something at the Planck scale.
