a macro study reveals the exact heart rate to minimize the risk of stroke

Nowadays we monitor our vital signs, such as heart rateon the wrist itself thanks to smartwatches and activity bracelets that constantly tell us how many beats per minute our heart beats at rest. This information is vital, since traditionally it is believed that having an excessively high number is an indication that something bad is happening in the heart. The middle point is the best. In medicine, both due to excess and scarcity, we can find a scenario that is pathological, and that is why, although we relate high heart rate as something very negative, we must keep in mind that having them excessively low It is not always positive. This is the main conclusion of a pioneering research presented at the European Stroke Organization Conference, and although it has yet to undergo review, its foundations are extraordinarily solid, based on the analysis of 460,000 participants over 14 years. Crossing data. Of all these people analyzed, the researchers were especially interested in their medical histories and the diseases they presented, highlighting the registration of a total of 12,290 cases of stroke during the decade and a half of follow-up. But what is truly important here is when these records were crossed with the resting heart rate data of the participants, discovering a very clear pattern by showing a risk graph in the shape of a ‘U’ and not a straight line. Its meaning. The fact that a graph with this shape has been generated tells us that the optimal heart rate level is between 60 and 69 beats per minute, since these people were the ones with the lowest risk of suffering from a stroke. The problem is that, when the heart rate at rest exceeds 90 bpm, the risk of suffering a stroke increases by up to 45%, both ischemic and hemorrhagic. But in the case of having excessively low heart rate, the risk also increases, so we cannot be completely calm if we have 50 bpm at rest. Atrial fibrillation. Until now, medicine was very clear that severe arrhythmias such as atrial fibrillation They were determining risk factors for suffering a stroke. But now this study adjusted the data specifically to separate people with and without atrial fibrillation, showing that resting heart rate is, on its own, an independent prognostic marker. Because? Although this study gives us a lot of information, the reality is that previous medical literature already offered a fairly rigorous explanation as to why a low or high heart rate had implications for strokes. In this case, an excessively low frequency can alter cerebral hemodynamics, causing blood to pass too slowly through the brain, and facilitating the formation of thrombi in certain contexts, especially when there are more risk factors. On the other side of the scale, when the frequency is chronically high, we have the layer of our blood vessels exposed to blood flow, exposed to constant mechanical stress that favors inflammation, hypertension and vascular damage, as has been shown in previous studies. Preventive medicine. These findings are good news for patients, especially older patients, since it is a new parameter that can predict the possibility of something as serious as a stroke occurring. This allows, especially in primary care, to better control the heart rate and not miss when it goes too fast or too slow, since the consequences can be fatal.

What it is, what dangers it has and what to do to try to minimize them

Let’s explain to you what is the practice of sharentingso that if you come across this term you know exactly what they mean. It has to do with things that parents do today, and is related to sharing their children’s content on social networks. And after explaining this concept to you, which you will see is something very easy to understand, we are going to tell you what are the privacy risks of sharenting in an uncontrolled way, and how you can avoid many of them. What is sharenting The term sharenting is a combination of the words share and parenting. It would literally be something like co-parenting, but taking it to a technological environment. What we mean by the term sharenting is when Parents share information about their children on social networkssuch as photographs, videos or other types of personal information. Parents usually do this in a well-intentioned way, simply so that their family and friends can see how their children are growing and the things they do together. However, when these practices are carried out without adequate precautions can put privacy at risk of the child both in the short and long term. What dangers can it have for children? Uncontrolled shareparenting without safety guidelines can have dangers for your son or daughter. It is important to think that everything you share publicly is available to everyoneso any stranger may have data or images of the minor. This, in extreme cases, can lead to misuse of these images or videos you share. The photos can be shared by whoever has access to them, and they can be used or manipulated for inappropriate contexts, and they can even end up on dangerous sites. It also means a security risk of the minors. Their routines, locations, and names may be exposed, leading to them being used for online harassment or phishing practices. And in the best case scenario, you will be creating a digital footprint too early without the minor’s permission, which can affect their future personal or professional life. Or maybe as they grow up they feel embarrassed or upset by the exposure that their parents made when they were little. How to avoid some of these dangers The first thing you have to do is be aware that what you share on social networks is public by default for everyone. If the minor is already old enough, the first thing is that you ask him or her for permission, so that they learn to be able to decide about their own image and privacy. Beyond that, it is important review the privacy settings of your social networks. On Facebook you can make the content not public, but visible only to your friends, and on Instagram you have settings such as best friends so that when you share something for them, only the people you have previously chosen can see this. It is also important do not show the minor’s face It is always something that will maximize privacy, especially when you want to share something publicly. For example, you can use safe photos, such as just your hands, and you can use use angles that do not reveal identity of the minor in the photographs. Furthermore, you must avoid giving personal datasuch as full names, addresses, locations where you usually move or school names. This data could be used for harassment or identity theft. It is imperative and important not to share compromising photossuch as with uniforms, swimsuits or in somewhat more intimate situations. These photos could be attractive to people you don’t want to be able to access them. And finally always think long term. Before publishing, think about how you would feel or how your son or daughter might feel when this photograph will still be public and online in several years.
