Insomnia occasional? The latest studies reveal that help can come from the correct hydration body, so if you want to rest well, don’t forget to keep the body hydrated during the day (to help you, you can remember to drink a glass ofwater every two hours). If instead theinsomnia is chronic, you have to talk to the doctor who will advise medications specific. But let’s explore together.

There is more and more scientific evidence that demonstrates how much a good sleep can positively affect the physical and mental well-being. Even with unexpected effects such as, for example, those on food choices.

In fact, sleeping well could help you avoid cheating at the table: a study published in the Journal of the American Heart Association highlighted how women sleepless they consume on average 500 to 800 calories more every day, abusing sugars and fats. This factor results in increased risk of developing obesity, type 2 diabetes and heart disease. “There lack of sleep unbalances the hormones that regulate the sense of satiety, so theappetite increases»Comments the professor Lino Nobili, neurophysiopathologist expert in sleep medicine and professor of child neuropsychiatry at the University of Genoa.

“But the link with cardio-metabolic diseases is even deeper, because theinsomnia compromises the natural reduction of cortisol at night: this hormone, known for its link with stress, keeps us in a condition of constant “excitement” and causes general inflammation in the body, at the base of arrhythmias, atherosclerosis, coronary heart disease, hypertension, stroke, but also of numerous other metabolic, cardiac and tumor pathologies ».

Not only: sleepless nights can also make skin diseases worse, respiratory disorders (including allergies) and all other pre-existing health problems: «Each of us has a target organ or a particular predisposition to get sick. And theinsomnia it induces an inflammation that uncovers this Achilles heel ”, explains the expert.

Why it is important to hydrate the body
There are many tools to address the problem. “If theinsomnia it is occasional, it can come in handy staying hydrated»Suggests the professor Alessandro Cicolin, neurologist, psychiatrist and head of the Center for the diagnosis and therapy of sleep disorders at the Molinette hospital in Turin. A recent study published in Sleep points the finger right at the dehydration: when we drink little the body produces higher levels of vasopressin, an antidiuretic hormone that helps to “save” the little water remained in the body, and this it seems to interfere with our biological rhythms, shortening the duration of the sleep about two hours.

When insomnia is chronic: the news
“In chronic lack of sleep, the one that persists for at least a month, instead there are more complex mechanisms ”, underlines the expert. «A revolution could come with the orexinergic drugs, under approval by the European regulatory authorities. These molecules act on oressine, the neurotransmitters present in the lateral hypothalamus, an area of ​​the brain where there is a sort of switch that controls the states of sleep and wakefulness“. A novelty that, in essence, wants to prevent nocturnal awakenings and could be added to the current simulator drugs adenosine, another neurotransmitter that accumulates in the brain during wakefulness and generates the classic feeling of fatigue that forces us to sleep.

Tank tops and T-shirts control rest

“The future looks not only to drug therapies, but also to new diagnostic tools”, continues Cicolin. Among the novelties in this field are the underwear, in different designs and colors, which they monitor how we rest.

The exceptional “stylists” are the participants in the Somnus project, which they created T-shirts, tank tops and other wearable devices that can measure heart, breath and other vital signs during the sleep. «Textile sensors represent the most modern evolution of actigraphy, the simplest and least expensive instrumental investigation for assessment of night sleep, which usually uses sensorized bracelets. And the diagnosis is crucial to distinguish theinsomnia from other disorders of the sleep, like the sleep apnea, sleepwalking or narcolepsy, to set the most effective therapy », concludes the neurologist.
