In a society where problems falling asleep are on the agenda, the promise of having a deep and restful rest It has become one of the great businesses of the 21st century. And faced with a silent epidemic of insomnia, millions of people have turned to a parallel pharmacy where no prescription is needed, since products such as melatonin, magnesium or CBD are available to anyone.
The melatonin paradox. Health authorities in the United States have been warning for years of a drastic increase in melatonin consumption among adults. It is perceived here as a “natural hormone” and therefore harmless, and although it is true that has proven usefulnessscience calls for curbing enthusiasm.
Here’s Duffy’s essay pointed Because at low doses it can improve the efficiency and duration of sleep, but what must be taken into account is the importance of following medical instructions to have a dose adjusted and controlled to the personal situation. It is true that there is still a lot of research ahead to determine the safety of melatonin supplementation, since some studies they even point to an increased risk of heart failure with taking for more than one year.
The CBD. Cannabidiol is another of the protagonists that is beginning to have more and more importance on the shelves of many people who have sleep problems. Unlike melatonin or magnesium, CBD is a compound derived from cannabis to “turn off” the nighttime mental noise. And here the science suggests that the effect of CBD is promising, but there is still a long way to go to determine its safety.
The most solid studies conclude that CBD is not a pure sedative, but that its greatest effectiveness is observed above all with patients whose insomnia is directly related to anxiety or chronic stress, since it can modulate the stress response, reduce nocturnal rumination and allows sleep to come as a side effect.
But they have problems. Right now, marketing inconsistency is a big drawback of CBD, as much of the failures reported by users are due to over-the-counter products that are not of the proper purity or concentration.
Magnesium. If there is a mineral that has capitalized on the attention on the internet in recent years, it is this one. It is promoted as the ultimate natural anxiolytic and sleeping pill; However, science suggests that they are greatly inflating the effects it has.
Here, as we have repeated on many occasions, supplementing when there is no deficiency of this or other minerals is not the best decision. Some small trials indicate that specific formats such as magnesium bisglycinate can provide modest improvements in cases of mild insomnia, but at a general level, the scientific community concludes that its “miracle pill” status lacks robust support.
Go to the doctor. On many occasions, when we have a problem, we want to resort to the miracle pill without doing anything else. When we are told about maintaining good sleep hygiene, keeping screens out of our sight several hours before going to sleep or forgetting about heavy dinners, the truth is that we find it complicated. Or at least more difficult than taking a pill they sell us, which will make us sleep without doing anything else.
It is for all this that it is always best to go to the doctor to determine what is underneath the insomnia, to be able to treat the root of the problem and not put patches on top, which is ultimately what is achieved with supplements.
