Wait, so even doing a head stand will put more pressure on the skull than you are able to do by pressing down with your hand? Is it still only 1 G force when doing head stand because I am standing still? Or is it my weight that plays a role here then?

Many people do head stands everyday and their skulls seem to be able to withstand this huge amount of pressure coming from their own bodyweight. What I'm wondering is if you can press down harder on your skull, creating a bigger pressure with your hands, than your own body weight is capable of (in a head stand).

You said that there were nerves outside the skull? So its those that makes me feel this occasional discomfort and as if there is some kind of constant pressure/tightness after pressure on the skull.

As in terms of DHMO, yeah I am a bit concerned considering it can be in food and such, but its more the thought of head injuries from external forces that gets on my nerves, because here you have a some control depending on how careful you are, and it's so easy to blame oneself for harming your own health due to stupidity.

DHMO is water. That site is a humor/gag site to fool people.

Mark is illustrating the persuasive power of the internet. ;)

Yeah that's what I thought, according to the chemistry formula DHMO = H2O.

EDIT: I just found out that since the head is shaped like an arch form it is very resilient towards a slowly/gradual increase in pressure as opposed to a sudden blow. I read that 50 psi can crush the skull in a sudden impact opposed to a gradual increase in pressure where 400 psi is required!

Anyways, totally stupid thing to worry about, but what are the symptoms of a fracture in the skull, would you definetely know if you had one? Or could you have it without even knowing...

mrsD is right. Minimac, the point is you need to put all of these issues in perspective based on complete factual information. There is a huge difference between doing stupid things and living a life in a very imperfect world. Hits happen. We can only do so much to reduce this risk.

Bumping ones head on a car door frame is an accident, not stupid behavior. We may struggle with balance and coordination and bump into things. That struggle is not stupidity. There are plenty of other accidents that can happen that are just accidents, not stupidity. Now, if one were to engage in risky activities and suffer a head bump, that would be poor decision making. There are ways to improve decision making skills.

We need to be able to live our lives without thinking everything we do is going to hurt us.

Regarding DHMO, Water is necessary for life. We live with it every day. We accept responsibility to minimize risks by not driving fast on wet slick roads, etc. But, we don't curse water and fear it at every turn.

The Serenity Prayer addresses these issues. Google it. You'll see what I mean.

My best to you.

I know it will always be uncertain circumstances, but I do wish to ask one final question, just to be sure I got the facts right. Gradual increasing pressure on the skull (applying pressure on the skull with weight as in using your hands) and a sudden forceful impacting blow to head causes the same kind of pressure on the skull right?

Sudden impact, and slow gradual exposure to pressure is the same thing am I right? Both scenarios apply pressure to the skull each in their own way?

Say for example you fall, the impact from the fall causes the same kind of pressure as in if you press down with your hand right? Of course the fall will result in far worse damage since speed, g force and a load of other stuff has to be taken in account. But principally the two things expose the skull to suffer from the same kind of thing? A blow and applied pressure has the same effects on the skull?

I may be repeating myself, but this pressure couldn't reach the brain without skull fracture right?

This'll be my last question, because I fear my thoughts will keep spinning for assurance which I simply cannot get as you implied :)

There is no comparison between pressure against the skull and the skull suddenly stopping when it hits a hard object. It is not the skull that is primary issue. It is the acceleration and deceleration of the brain and what happens when it hits against the inside of the skull.

I don't understand the purpose of this question. Are you letting somebody press on your head ?

No I accidentally pressed too hard down on my own head to correct my hair because it was popping out, pressed so hard it caused discomfort for a short while. And well yeah, it basically made me worry.

The pressing on your head did not cause anything other than a surface irritation. Your anxiety has turned it into a multiday waste of your time and emotional energy. You seriously need to find someone who can teach you anxiety reducing skills. Your life will be miserable unless you can get control of your anxiety ridden thoughts.

You also need to learn to just trust people who are more knowledgeable then you. You don't appear to have the reasoning skills to properly understand concepts like this. That is understandable. Not many people can grasp the complex issues of G's forces and pressure. So, please try to stick with the hard boiled egg analogy. It is probably the best way to understand the pliability of the brain.

My questions and concerns have been more infrequent lately, which definitely is a huge positive for me, and I plan to keep it that way. Though something has come up even though I slowly refrain from using this forum for answers, as it actually does end up making it worse if it gets too excessive, so i'm gonna have to use this forum in healthy moderation as goes for everything.

These last days a very small but hard metal object hit my head, well actually I was holding the metal object in my hand and had to scratch the back of my head when the blunt grip of the knife accidentally hit my head. My question is this, would a small moving object impacting the head only affect the skull since the actual head isn't moving at all? I mean the smaller the object the less impact frequency right? The less the head moves. I am sure my head didn't move at all during the impact so does the skull simply do it's job and absorb all of the forces? Or can a concussion actually still potentially occur in such a case? And another little concern is the hair roots and follicles. Can they get damaged during blunt or sharp edged trauma? I think I might have stabbed my head slightly with the pointy edge of the knife too, no bleeding or anything, but could it still permanently damage the hair roots? Or are the roots sitting at the bottom of the scalp? I am worried they are placed at the surface. And also, does a sharp edge increase the odds of a concussion? Generally I believe a knife is too lightweight to cause any concussive blow and also it wasn't even sharp enough to cut through skin, only the pointy edge was somewhat sharp which unfortunately came into contact with my scalp too.

It does not sound like the forces were even close to being a sub-concussive blow. The point of the knife concentrated the energy but still was not intense enough to cause a problem. Hair follicles are quite resilient. It takes serious skin damage to scar over the follicles. I doubt this happened.

My best to you.
