How do fire walkers actually walk on fire?

Fire walking is the act of walking barefoot over a bed of hot embers or stones. Fire walking has been practiced by many people and cultures in all parts of the world, with the earliest known reference dating back to Iron Age India – c. 1200 BC. It is often used as a rite of passage, as a test of an individual's strength and courage, or in religion as a test of one's faith. Some countries have fire walking in their culture which determines their faith and tells they’re strength.

Modern physics has explained the phenomenon, concluding that the amount of time the foot is in contact with the ground is not enough to induce a burn, combined with the fact that embers are not good conductors of heat. This means that your feet can only get burned if you stand on the fire lit hot stones for a long period of time. Surprisingly, one is more likely to be burned when running through the embers since running pushes one's feet deeper into the embers, resulting in the top of the feet being burnt.

Hi Biloela,

I think you are right, I believe you are going through indigestion. Indigestion is the pain or discomfort in the stomach associated with difficulty in digesting food. Indigestion can happen when someone:  Eats too much, eats too fast, eating high-fat foods, or eating during stressful situations, Drinking too much alcohol, Cigarette smoking, Stress and fatigue and stomach infections. Antacids neutralize the acid made by your stomach. Antacids are alkaline because indigestion creates more acid in your stomach which therefore, means to neutralize the acid in your stomach you would use an alkaline (Antacids). Antacids work by neutralizing the acid in your stomach that is used to aid indigestion. This can reduce the symptoms of heartburn and relive pain.

About what your Gran mentioned that Baking soda is an Alkaline, she was correct! She was right about using baking soda as an antacid, if baking soda is dissolved into water it can be used as another form of an antacid however, researchers say if you take too much baking soda, as with any antacid medication, then you will neutralize the acid in the stomach itself. This may lead to headache, nausea or irritability. The levels of stomach acid can be reduced to such a degree that digestion is impaired and food not properly broken down. This in turn can lead to allergies and inflammation in other parts of the body.

There are other antacids that can be taken other than baking soda. One of them is calcium carbonate, this medicine helps relieve the symptoms and discomfort of heartburn and indigestion. The active ingredient calcium carbonate is an antacid and works by neutralizing excess acid in the stomach. This helps relieve the discomfort and symptoms caused by acidity such as heartburn and indigestion. This medicine is available as tablets that have to be chewed or sucked slowly before swallowing. Another form may be a liquid such as the Gaviscon® Regular Strength Liquid Cool Mint Flavor, the active ingredients include 95 mg of Aluminum Hydroxide and 358 mg of Magnesium Carbonate per tablespoon. The most effective antacid according to research is Mylanta. I hope you feel better soon with the advice that i have provided above!

Sincerely,

Dolly Doctor.
