If we had to choose a partner for life, one who brings to mind moments from our childhood, who makes us jump for joy, reminds us of that special someone, gives us goose bumps, makes our heart race or even makes us cry, most of us would agree on their name: MUSIC.
Music is one of the greatest sensory experiences that exists. It has even been proven that humans learn to emotionally respond to music before emotionally responding to words.

The connections that are produced in the brain when listening to music give it a strong ability to relax us, energize us, increase our concentration or even help distract us from pain.
For some of these reasons, we can also say that music is a means of communication and socialization. Thanks to music, we share sensations with unknown people, like when the audience of a concert is connected by the same melody, or when listening to certain notes you feel the need to dance.
Music is also known to provoke visuals of colors and shapes (this occurred with Russian painter Vasili Kandinsky), and it is sometimes directly linked to science and the universe. But its trivial use within the world of marketing cannot be ignored either. In consumption-based environments and nightlife spaces, music becomes the key tool to boost the demand for a product.

Sometimes it acts as a refuge, when we need to vent in private, the company of a song can give a little more meaning to the moment. For this reason it is actually used often in therapies, because what sometimes we cannot achieve with words, we can with music, creating connections even among different classes of living beings.
We could write an endless list of sensations and explanations about the effects of music on our brain and therefore on our body, such as the increase of physical endurance (due to musical stimuli) or the control of the cardiovascular system, but this time we want to highlight music as a driving force of memory. Its effects are so intense that a reaction to a song can bring to mind a forgotten moment even for people with memory problems.

We often speak about the sense of smell and the scents of Per Purr as a way to transport us to other spaces. But today we wanted to highlight this element that seems to have accompanied people for more than 8,000 years and is present every day in our offices and laboratory in Madrid. Music helps us to create an energetic and positive atmosphere, and we’d like to share that with you with this playlist:
Enjoy yourself and your surroundings, with music and Per Purr!

Revered as divinities or repudiated as a symbol of evil. The truth is that the story of our dear cats is almost enigmatic as they are, but why are we telling you this?

In case someone has overlooked, the Per Purr symbol and icon it is a cat. The reason is not only that Tahone Jacobs (co-founder of Per Purr) is a cat lover of, but we believe that they are a great example of self-care.

Another great feature that does not go unnoticed in these curious animals is the general state of calm in which they live, since they spend most of their time enjoying the peaceful protection of home.

There are many theories on the coexistence between cats and man and, although the dates continue to change, it cannot be denied that this species, known for its seven lives, has shared its existence with people for more than 10,000 years. So we want to take this opportunity to demystify that cats are "uncaring", bring bad luck or reject human company. Since these statements seem to be more related to the terrible theories of the Middle Ages, used to justify cat torture.

A very curious fact is that 90% of the cat's brain is similar to ours, since they have the same regions dedicated to emotions as we do. It may be for this reason that they are so insightful when it comes to feeling the emotional state of those who share their environment and for this reason, they are also very helpful in therapy with children and people with emotional and social problems.

Although we are not going to stay only on the emotional side, the truth is that one of the great facets that fostered the relationship between cats and people was the hunting of rodents, that is why the cat is also associated with fortune and good, because thanks to cats the crops came out ahead. However, it was the Egyptians who had the greatest fame when evaluating the independent, noble and (again) sensitive character of small cats. In addition to their outstanding hygiene, with which they stimulate circulation and refresh the skin.


"Cats have absolute emotional honesty: Humans, for some reason, can hide their feelings, but a cat cannot." - Ernest Hemingway


Associated with the charisma there is something that makes them very unique over the rest of the animals, and it is not the fact that they walk and run moving the 4 legs in the same direction (this is also achieved by giraffes and camels). The purr (purr in English) is, without a doubt, another of the mysterious wonders around cats.

The peculiarities and effects of this action have been discussed and discussed on a large number of occasions. French veterinarian Jean-Yves Gauchet has demonstrated, under the name of purr therapy, that the sound of purring stimulates the neurons that produce serotonin (the well-known hormone of happiness).

Whether or not it is due to the power generated by the vibration of the purr, it is true that this act manages to transmit a great feeling of calm and well-being in people. And it is that the purr is not used by cats only as an expression of well-being, They are used as a calming tool in stressful situations or to accelerate their healing process after suffering fractures or wounds.

For these and many more reasons, at Per Purr we are unconditional cat lovers  and therefore we also recommend that you be a little more “cat”, pamper yourself, relax and, if you want, also purr with pleasure.


No es ningún secreto que el deporte es una de las mejores actividades que podemos realizar. La lista de sus beneficios físicos es bastante amplia, desde la estimulación del músculo cardiaco y la reducción de la presión arterial hasta el fortalecimiento de la estructura muscular esquelética, pero tampoco queremos dejar a un lado su otra cara buena.

Si bien es cierto que en estos días no es posible realizar una actividad física grupal o al aire libre, podemos replantearnos la forma de descargar nuestra energía y pensar en lo que haremos después. Siempre es bueno direccionar nuestro presente hacia el futuro, pensando en que lo que hagamos hoy tendrá su efecto mañana.

Aparte de las modas, no podemos olvidar que el ejercicio físico forma parte de nuestra vida casi desde bebés; cuando nuestras madres y padres nos mueven las piernas y los brazos para que fortalezcamos nuestras articulaciones. Después descubrimos lo que es el equilibrio y no dejamos de levantarnos al caernos, aprendiendo lo que es la persistencia. Mejoramos nuestras capacidades con lo que creemos que son juegos y en realidad estamos ejercitando nuestro cuerpo. 

Parece que a veces no sabemos dar tanta importancia al deporte, pero por alguna razón es también una parte imprescindible de nuestra educación. El deporte nos ayuda a tener un mayor conocimiento y control sobre nuestro cuerpo. 

Aunque en algunos casos la actividad física diaria no sea colectiva, todos hemos practicado deporte formando parte de un grupo y, sin darnos cuenta, gracias también a ello hemos aprendido lo que significa la palabra equipo, algo fundamental en todas las etapas de la vida.



Desde la Edad Antigua la educación espiritual se conexionaba con la física. Y es que la unión entre el cuerpo y la mente siempre ha sido fundamental para la promoción del cuidado, el respeto o la libertad. Un claro ejemplo fueron las escuelas gimnásticas del siglo XIX, donde el ejercicio iba ligado en todo momento al aprendizaje de valores como la honestidad, valentía, compañerismo o la fuerza de superación.

 Mucho más allá de los datos de la historia está comprobado que el deporte ayuda en la prevención de las conductas antisociales, mejorando la responsabilidad personal y social mediante las habilidades de comunicación y cooperación desarrolladas. Pero, ¿qué relación o efectos directos tiene sobre la mente?

El deporte nos ayuda a completar las tres necesidades psicológicas básicas según la teoría de la autodeterminación;  la cual vincula personalidad, motivación humana y funcionamiento óptimo en relación a los factores que estimulan el tipo de actuación en las personas. Estas necesidades (autonomía, competencia y relación social) son fundamentales también para el bienestar y crecimiento personal. 

El deporte, concebido desde un aspecto positivo y controlado, ayuda a reducir la frustración ante determinadas situaciones y con ello también la ansiedad o la posibilidad de sufrir depresión

Cuando el cerebro considera alguna situación amenazadora libera neurotransmisores del estrés que alteran nuestro razonamiento y percepción del bienestar, no obstante, gracias al deporte se desarrollan una serie de valores que fomentan el autocontrol y así nuestro cerebro consigue relajarse y procesar la información de manera más racional ante ciertas situaciones. Además de la ya conocida producción de endorfinas, conectadas con las sensaciones de bienestar, placer y optimismo tan necesarias en estos días.

Melatonin is a hormone that regulates the sleep-wake cycle by causing drowsiness and lowering body temperature through sensitivity to ambient lighting. It works best at night with the natural circadian rhythm. While sleep is incredibly important, melatonin also operates directly with the central nervous system, which ultimately really puts us to sleep.

In the 1990s, it was discovered that melatonin had other functions in our bodies, such as the elimination of free radicals, which makes it an endogenous antioxidant. Need more?

It is not just an antioxidant, it is a super antioxidant.

It can cross cell membranes and also the blood-brain barrier, a filter that regulates fluid and materials that enter the central nervous system. Upon entering, and unlike other antioxidants such as vitamin C, vitamin E, and glutathione, it does not undergo the “redox cycle”. The redox (reduction-oxidation) cycle occurs when an electron-poor antioxidant, such as those mentioned above, donates its electrons to cancel the effects of free radicals (highly reactive molecules that cause damage precisely because they do not have paired electrons, and molecules that need electrons to stabilize). Because they don't have a lot of electrons to donate, they can become “pro-oxidants”.

Melatonin is an electron-rich molecule and can interact with free radicals through an additive reaction, forming various stable-end products excreted in the urine. From this point of view, melatonin can be considered a terminal antioxidant. Many already know that its production is directly related to sleep cycles. But what few know is how good it can be for the skin.

From the age of 30, the synthesis of melatonin begins to decrease, which explains the insomnia crises of adulthood. Melatonin deficiency is also related to depression and obesity. But what does it have to do with beautiful skin? As we said before, melatonin decreases cell oxidation endogenously, being one of the most powerful antioxidants ever found in nature.

Antioxidants in turn decrease the premature aging of cells and, consequently, the skin; smoothing and preventing wrinkles and eliminating the "tired" appearance that we dislike so much. It also helps control changes in skin pigmentation by adding melanin to melanocytes, causing the skin to change color. This interaction is also responsible for the paler color of the skin of the elderly and people suffering from insomnia.

In addition to skin pigmentation, it is also related to melanoma control, because melatonin receptors are expressed in various skin cells, including keratinocytes (keratin-producing cells, predominant in the epidermis) and fibroblasts (cells related to healing and other functions). Melatonin can also suppress ultraviolet (UV) light that causes damage to skin cells, exhibiting strong antioxidant activity in cells exposed to UV rays. Therefore, melatonin synthesized locally or topically applied* could neutralize environmental stress.

Our skin acts as a barrier between the environment and the grand organism (our body), since it is constantly subject to the actions of solar, thermal, mechanical energy, chemical and biological agents. Evolution has allowed it to develop unique properties to deal with these stressors, making it endowed with abilities to recognize, discriminate, and integrate specific signals within a highly offensive environment and integrate them into a neuroendocrine and stress response system. Further,  the skin has the ability to generate new vessels, cellular tissues, and rehabilitate scars and wounding.

Melatonin is not yet used in sunscreen creams, probably due to incompatibilities with the substances used to protect against UV rays, which require a very high pH to be stable. But the use of its properties for topical purposes is already being used in humans: melatonin in a pliable cream formulation can form a deposit in the first layer of the skin from which is continuously released into the blood vessels. Thus,the skin becomes a target organ, not only for the treatment of local routes, such as topical application, but also allowing a transdermal supply (that passes through the skin) reaching our circulatory system, creating internal treatment through this constant within the skin.

We leave you a list of foods that help in the production of this hormone: oats, berries, corn, red wine, tomatoes and oranges, potatoes, nuts and rice.

Easy, right? Nothing outside of our usual diet.


In addition to the food, to have a better production of melatonin, we must monitor environmental factors: seasons, temperature, ambient lighting, and endogenous factors such as stress and age. The story that you shouldn't sleep with the lights on, or with the TV on, can be considered correct. If there is a minimal light source in the room or if the temperature is not pleasant, you can have an uncomfortable night or a series of them. It must have happened to you, right?

Melatonin in supplement form is easily found in drugstores.

Some Pointers:

  1. If you live in the far northern hemisphere with endless days in the summer and it takes you forever to fall asleep, try to close the blinds "early", since it takes about 4 hours for the body to assimilate the darkness and start producing melatonin.
  1. Eat the aforementioned foods within a varied diet.
  1. If you travel a lot and have problems with jet lag, or have a crazy routine, or just want to sleep better every day, we recommend taking melatonin as a supplement (restful sleep and beautiful skin!). 
  1. *There are also options with melatonin for topical use in all pharmacies such as serums, ampoules and creams.


So, sleep tight! We are working for taking care of you!
