Answer 1

you probably just locked your knees. When you do that it's harder for your body to circulate the blood for some reason. Most military guys know when you stand at attention never to lock your knees or you will pass out.

The light headed thing is u were about to pass out.

Answer 2

I think you had an episode of heat exhaustion due to standing and sweating and being in a n overcrowded place.


What are the differences in heat exhaustion and heatstroke, and what steps can be taken to prevent them?


Heat exhaustion is caused by the loss of a large amount of fluid in the body because of excessive sweating.

Symptoms are weakness, dizziness, nausea and headache, possibly leading to collapse. The skin is cold and clammy, and pupils of the eyes are dilated. The body temperature is usually normal, but blood pressure might be low.

A person with heat exhaustion should be moved to a cool place and put in a head-low position.

Heatstroke occurs when the body becomes dehydrated and can no longer produce sweat, which aids the cooling process, or when there is very high humidity, which prevents the sweat from evaporating.

This is a medical emergency normally accompanied by a high body temperature (usually above 105) without sweating. Other symptoms include headache, numbness, tingling and confusion prior to sudden delirium or coma, fast pulse, rapid breathing, and elevated blood pressure.

In such cases, medical attention should be sought immediately.

The risk of hyperthermia (getting too hot) is greater if you have heart, lung or kidney disease, slowed circulation, obesity, or any condition that causes weakness or fever, or if you drink too much alcohol.

Symptoms of hyperthermia include heat cramp, heat exhaustion and heatstroke.

A person with heatstroke requires rapid cooling (such as being placed in a bathtub filled with ice-cold water) and medical attention.

Here are some steps you can take to reduce your risk of hyperthermia and its consequences:

• Drink plenty of water and juices; avoid alcoholic beverages

• Bathe or shower frequently using cool water

• Wear lightweight, light-colored, loose-fitting clothing

• Avoid vigorous activity from noon to 4 p.m.

• Wear a hat or use an umbrella in the sun

• Use fans and air conditioners liberally. Visit air-conditioned places such as shopping malls and libraries, but avoid overcrowded areas.

• Avoid eating heavy meals and limit oven -use.

Answer 3

Maybe stress, feeling under pressure because of the situation. Maybe a mild panic attack. I think that's what it was.
