Factors that influence fainting are taking in too little food and fluids, low blood pressure, hypoglycemia, growth spurts, physical exercise in excess of the energy reserve of the body, and lack of sleep. Even standing up too quickly or being in too hot a room can cause fainting. Recommended treatment is to allow the person to lie on the ground with his or her legs a little elevated. As the dizziness and the momentary blindness passes, the person may experience visual disturbances in the form of small bright dots (phosphene). These will also pass within a few minutes. If fainting happens frequently, or if there is no obvious explanation, it is important to see a doctor about it.
More serious causes of fainting include cardiac (heart-related) causes such as an abnormal heart rhythm (an arrhythmia), where the heart beats too slowly, too rapidly or too irregularly to pump enough blood to the brain. Some arrythmias can be life-threatening. Other important cardiac conditions that can manifest with syncope include subclavian steal syndrome and aortic stenosis.
Fainting can also be due to neurological disorders, stress, side effects of anaesthetics, etc.
Fainting involves a temporary reduction of blood (and therefore oxygen) supply to the brain, resulting in a blackout. Many forms of syncope are benign and easy to associate with clear precipitants that can be avoided.

Fainting can be related to many different things. More than one thing may be the cause of it.
Fainting can happen when not enough oxygen flows through your blood and into your brain. You lose consciousness, or "pass out," for a very brief time -- just a few seconds or minutes.
A sudden drop in your blood pressure can cause you to faint. Sometimes your heart rate and blood vessels can't react fast enough when your body's need for oxygen changes. This is very common among older people. It can happen when:
You stand up fast.
You work or play hard, especially if it's very hot.
You begin to breathe too fast (called hyperventilating).
You get very upset. Being upset can affect the nerves that control your blood pressure.
You're taking medicine for high blood pressure.
Coughing, urinating and stretching can also get in the way of the flow of oxygen to the brain and may be a cause of fainting. If you faint once during one of these activities, it's probably not something to worry about. But if it happens more than once, you should tell your doctor about it.
If you faint when you turn your head to the side, the bones in your neck may be pinching on one of the blood vessels that leads to your brain. If this happens to you, be sure to tell your doctor about it.
A drop in your blood sugar may also cause you to faint.

Lack of Oxygen/ Blood to the brain. It is a defense mechanism of hte body. Once we pass out, the head drops lower than the heart, restoring the blood flow.

Fainting usually cause by weakness and dehydration or mostly when one is working near furnaces.

Possibly low blood pressure, or low blood sugar.
I occasionally suffer the same if i have either!
Something he should keep in mind and monitor, but luckily not overly serious!
