ruining

We carry a great spell of rain and overcast skies in much of Spain, and this also translates into a strange sensation in our body when we feel stuck in the chair, depressed and even taciturn. And it’s not that we’ve suddenly become lazier or sadderbut it is pure and simple biology that has humidity, microbiology and brain chemistry as triggers. Our ideal humidity. To understand why we can feel so bad, we have to understand what our body needs. Here science already pointed out many years ago that our body is designed to ‘function’ in a narrow range in terms of relative humidity.: between 40 and 60%. In this case, when we are outside this range for a long time, which is typical with these rains where the humidity shoots above 70%, it is when everything changes. And above all it affects those people who are not used to so much humidity and who have not adapted to it, such as those who live in areas that are traditionally very dry. What happens. In these cases, when we are in a situation of very high humidity, science suggests that the defenses let their guard down. Above all, it affects the mucous membranes, which are our body’s first defense barrier, which is compromised. In this case, while very dry air can crack the mucous membranes that require a certain humidity, when you have air with a lot of accumulated humidity, a ‘party’ is organized for the pathogens. The scientific reviews point here that excessive humidity favors the survival of bacteria and viruses, increasing the environmental viral load. The effects at home. If we suddenly feel short of breath or that the asthma that had been controlled has returned, the fault lies precisely in what we do not see. The WHO itself and the CDC have established direct links, since they suggest that structural and environmental humidity turns the house into an incubator. The attack of mold and mites. One of the most important points is in the miteswhich are microscopic organisms that do not drink water, but rather absorb moisture from the air. In cases where humidity exceeds 70%, their population explodes and, according to evidence, this can trigger allergic exacerbations in those more sensitive people. Mold is also one of the main protagonists in these cases, and you just have to see how easily it can appear in bathrooms without ventilation. And even if black spots are not seen, the spores can be in the rooms of the house. The science here is clear: exposure to moisture and mold in the home increases the risk of developing asthma by 30-50%. The effect on the brain. But what we notice most every day is that feeling of being “moody” or “stuck.” And here the person responsible is the lack of light due to being cloudy all day. The neurochemistry here is quite important, since without bright light to tell your brain “it’s daytime”, your body continues to produce melatonin, which is the sleep hormone, during the day. The result here is in fatigue throughout the day and apathy that makes us not want to leave the couch. There are also deficits. But in addition to melatonin, the lack of sunlight in those areas where it is not usual produces a decrease in the production of serotonin, which is one of the neurotransmitters responsible for mood. Less light equals less “fuel” to feel good. AND We must not forget about vitamin D either.which depends on sunlight to maintain optimal levels. Although supplementation has mixed results, observational studies are clear: there is a direct correlation between rainy months, low vitamin D and irritability or depressive symptomsknown as Seasonal Affective Disorder (SAD). What can we do? Although it may seem counterintuitive, the European Lung Foundation point because you always have to ventilate the house a little even if it is raining. The accumulation of internal humidity from our own activities such as cooking, breathing or showering, added to the external humidity, creates a toxic environment. That is why maintaining air circulation and, if possible, using dehumidifiers to try to return your home to that sacred 40-60% range, is the only way to mitigate the impact on some part.
