Reasons for Fainting
Fainting episodes may be once in a while condition that one may suffer or may become a frequent phenomenon. Fainting is mostly a situation that arises due to exposure to certain environment or trigger factors that act on the body.
It may be due to internal factors like lack of essential nutrients or minerals that help in effective functioning of the body, hormonal changes, dip in energy levels, low levels of sugar or electrolytes etc. External factors could be triggering agents too and it will vary from person to person.
One of the reasons may be heat and direct exposure to harsh sunlight. Traveling during afternoon time without using any protective gear to avoid direct contact with sun rays may lead to sudden feeling of exhaustion, may lead to heatstroke and one may go through a fainting episode.
Sudden dip in the level of sugar, salt and electrolytes could trigger a fainting spell. There should be a balance of sugar and salts in the body. Natural sugars like glucose, fructose, and electrolytes and salts help in maintaining a balance and energizing the body. In case of any imbalance, fainting may occur.
It may happen also when there is no intake of food, if one has skipped meals, is working in stressful conditions without adequate intake of nutrients, fainting could be a natural response. It may happen to those who are fasting, or those who are on outdoor jobs and do not eat on time.
Fainting or unconsciousness may happen because of stress, lack of adequate rest and relaxation, compromising on the hours of sleep etc. For example, children may faint during exam time if they read late into the night, are tensed and stressed due to the pressure of examination and go for exams on empty stomach.
Sudden stress or shock may also trigger fainting. For example, on hearing the news about death of a near and dear person, hearing about death of a child or spouse gives rise to acute stress due to which there may be black out, unconsciousness or fainting.
It is also a reaction to panicking, anxiety attack and nervousness. Paranoid fear about an event, persistent stress, worrying, mental agitation and exhaustion may lead to light headedness and fainting.
