The valsalva maneuver

This is a totally new term for me - the valsalva maneuver. It's what you do when you are about to lift something really heavy - you breath in, hold your breath and tense up your whole body.

So, this action is perfectly normal but according to iForm, due to a misunderstanding in the 90:s people have learnt to not hold their breath. Apparently physio therapists taught people with back problems to exhale when they did sit-ups. This has then spread to healthy people, thinking they were clever... It's true that the blood pressure rises, but that is not in any way unhealthy for a healthy person. So, forget about it. :)

But what does this mean to martial arts? You never hear a boxer holding his breath. Could it be you should hold your breath in the very instant you hit, and then right afterwards breath out, in order not to stop breathing?

Rökning dödar fortare än man trodde

Ja, surprise... Denna artikel belyser en undersökning som visar att rökning dödar snabbare än man hittills trott. Det ska verkligen bli intressant att se hur forskningen ser ut om några decennier - hur folk förfasar sig över den kemiska cocktail vi bäddar vår mat och våra kroppar i, inklusive smogen av strålning i alla frekvenser (oljud, mobilstrålning, kärnavfall etc). När ska politikerna fatta vilket oerhört högt spel vo spelar???

Cerebrospinal fluid rhinorrhea

Cerebrospinal fluid (CSF)is what our brain floats in in our skulls. Up to half a litre is produced every day (20 ml/h) and is then absorbed by the body. But it might also escape through holes in the brain cavity. Rhinorrhea means runny nose, so if you experience a runny nose for a long time, CSF Rhinorrhea might be what you have. This doesn't have to be as bad as it sounds, as en increased brain pressure could lead to the tissue weakening and in the end CSF escaping into the nasal cavity and out the nose. This is called a spontaneous CSF rhinorrhea. Of course you should check it out!
