We often end up operating at a much higher pace than our bodies can actually handle. We push our bodies to the limit and we tire ourselves out. We work eighty hour weeks and then are surprised when we feel like we need to spend the whole weekend in bed recovering.
We make our bodies obey; we make sure that we don't need sildenafil citrato farmaco generico until it is absolutely necessary. Has it ever happened to you that you work those long hours at work and you have deadline and after deadline. After each deadline you say you will rest, take a day off.
But of course you never do. And eventually your body simply cannot handle the strain and you get sick, really sick. This often happens at a change of season when your immune system is vulnerable, but it also often happens the moment you let yourself relax.
You have been forcing your body to push through to the next terribly important thing and then you take that well earned break and the very next day you have the worst flu you've ever had. This happens because stress actually puts extra strain on your body.
It can go just so far and no further. And though being sick is really awful it may be the only way your body can actually force you to take a break.
