Why the hell do you feel so sleepy and so reluctant to work when it gets warmer outside? Yesterday was good, right? When it gets cold, it’s not so scary. That is, of course, we grumble, curse the climate of our homeland and its utilities, discuss the advantage of Canadian down jackets over Greek fur coats, but we do not sleep. In frosts we are angry and cheerful. But when life gets better, I want to curl up and complain about life without getting out from under the covers.. What is the reason for this, the doctors of the Atlas clinic explain.
Changes in atmospheric pressure have the strongest effect on health. The approach of a cyclone bringing overcast, unsettled weather with rain, fog and gusty winds is it. The norm of atmospheric pressure averages 760 mm Hg. Art., falling by 6-8 mm Hg. Art. per day significantly reduces the oxygen content in the atmosphere.
Under such weather conditions, the partial pressure of oxygen in the blood decreases, due to which less vital gas is supplied to the tissues and organs than in normal weather. The result is hypoxia. When tissues and organs are not sufficiently supplied with oxygen, the body begins to defend itself and saves energy, trying to hibernate. By the way, the same thing happens when climbing mountains.
Cooling – increasing pressure – does not give such an effect. But hypertensive patients tolerate it worse: their blood vessels constrict, palpitations begin, shortness of breath, and even a hypertensive crisis can happen.
Have you noticed that warming almost always coincides with cloudy weather and snowfall? And you have already gone through how the lack of light affects the body.
Frost, especially sharply struck, is always “frost and sun.” Therefore, most of us are quite cheerful when it gets cold. Under the influence of light, the body produces vitamin D, which is necessary for activity, and the hormone cortisol, which is also called the stress hormone. Cortisol has a catabolic effect, which means it increases the availability of nutrients by increasing their concentration in the blood, which provides the body with a burst of energy.
Now imagine that clear weather is replaced by cloudy – and you get out of the house under a gray sky with dark clouds. Naturally, with such a picture of cortisol and, subsequently, vitamin D, the body will not be enough, as a result, it will be difficult to get up, and you will want to sleep all day.
