Question

Workers in deep mines usually suffer from dehydration because

• A. Water is lost due to evaporation.
• B. Water is lost due to defeacation.
• C. Water is lost in the form of urines.
• D. Water is lost along with salts in the form of sweat.

Answer 1

The correct option is D Water is lost along with salts in the form of sweat.

Mine sites are often described as being hotter than hell. The hot ambient temperatures, long days and extended work cycles often experienced by mining workers are sweltering and this causes a gradual increase in the accumulation of dehydration in workers. Dehydration along with the loss of water also cause loss of electrolytes (salts). Electrolytes play a vital role in muscle contraction, nerve reactions and regulating fluid levels. Imbalance of these electrolytes can cause fatigue and muscle weakness, dizziness, nausea and sometimes fainting. Some of the common symptoms for mild to moderate dehydration are thirst, dry mouth, fatigue, tiredness, decreased urination and urination dark in colour, dry skin, headache, dizziness, and lack of concentration. If the symptoms of dehydration are ignored it can escalate to heat exhaustion and heat stroke which can be life threatening. So, it is important for workers to be proactive in preventing dehydration when working in high risk environment like mining.
