Less sleep: less life and more urgency, war energy

Sleep is a modifiable behavior, and improving its quality and duration can be an effective strategy for extending life expectancy.

Getting less than seven hours of sleep per night isn't just bad: it shortens your life.In a recent study published by the Society for Sleep Research, data from more than 3,000 counties in the United States between 2019 and 2025 confirmed this.The relationship was strong and persisted after adjusting for smoking, smoking, diet, physical activity, and economic variables.Although this is a randomized study, the breadth and consistency of results over time, including epidemiology, strengthens its validity.Smoking remains a major predictor of death, but sleep deprivation appears to be an independent and important factor.

We know very little about the biological mechanisms linking sleep to impulsivity, and both to longevity.Complex processes are involved—metabolic, hormonal, and neurological—about which we know only a few biochemical details.However, at the psychological and behavioral level, there is a lot of knowledge on how to regulate and improve sleep, and, as teacher Eduardas Estivilas reminds, the importance of these findings is obvious: sleep is a modifiable behavior, and improving its quality and duration can be an effective strategy to increase longevity.

Lack of sleep increases rigidity, at least through genetics, and supports risk responses and messages.A need for knowledge and attention to criticism is also conducive to quick emotional responses."Delayed discounting"—the importance of immediate rewards over important things, but in the future—is a manifestation of hastiness in decisions.Its biological basis is partly hereditary (about 40%, e.g. according to twin studies). A recent study in molecular psychiatry, led by Spanish researcher Sandra Sánchez-Roge in California, analyzed the genetic records of 135,000 people and identified 93 genes associated with this disease.Many of the reward changes associated with dopamine signaling—key to the development of the cerebral cortex and neuronal metabolism.Impulsivity is polygenic: it does not depend on a single gene, but with many subtle and overlapping effects; however, surprisingly, 73 of these genes are associated with other conditions such as ADHD, depression, risk-taking behaviors, obesity or heart disease, and poor emotional regulation.Surprisingly, they are not (or very weakly) related to education.

However, genetics only defines trends.Environment and habits can change them or even counteract them through epigenetic mechanisms.Donald Trump said that sleeping is a waste of time and sleeping 3 to 5 hours a night would reinforce pre-existing impulsiveness, perhaps influenced by other life experiences: a family environment with little room for weakness;the culture of risk and quick reward in real estate;or media and political reinforcement for immediate and powerful countermeasures on television.

But it is clear that the chromosomal data do not end with causation: without examining the DNA sequences, the speculations will be spurious, but it cannot be ruled out that some investigative centers have this information.It can reflect how lifestyle, sleep, or environment modulates gene expression—it's easy to get and fill it with epigenetic data.This will allow us to know better than to wait.

With less escalations, from a more transparent perspective, the character moves well in volatility, pulling the strings (oil, stock markets), always placing their own financial interests and getting some at the center axis of their actions.Besides the conventional arms companies, Trump's oil companies, Putin and even Repsol — with some strategy and some recovery — are the winners of this war, whether it ends or not.But if those of us labeled as losers ignore them, they will be less.I am not surprised by the anger in Spain and almost all of Europe.
