…Not drinking enough water can become dangerous faster than you think
By Dr Tariq Jagnarine, Fam Med
Why this matters in Guyana
Guyana’s warm, humid climate means the body loses water quickly through sweating, even during normal daily activities. For people working outdoors, such as farmers, miners, vendors, and construction workers, the risk is even higher.
Despite this, many people do not drink enough water throughout the day. Some rely on sugary drinks, while others simply ignore thirst. The result is a growing but often overlooked problem: dehydration and heat-related illness.
What is dehydration?
Dehydration occurs when the body loses more fluids than it takes in. Water is essential for maintaining body temperature, supporting organ function, and maintaining stable blood circulation.
Even mild dehydration can affect how you feel and function. More severe dehydration can lead to serious health complications.
How heat affects the body
When the body is exposed to heat, it tries to cool itself by sweating. This process leads to loss of water and important salts. If fluids are not replaced, the body struggles to regulate temperature.
This can lead to a range of heat-related illnesses, from mild discomfort to life-threatening conditions.
Signs of dehydration
Early signs include thirst, dry mouth, fatigue, headache, dizziness, and reduced urination. Urine may appear dark, which is a common warning sign.
As dehydration worsens, symptoms may include confusion, rapid heartbeat, weakness, and fainting. At this stage, urgent medical attention may be required.
Understanding heat illness
Heat illness occurs when the body can no longer cope with high temperatures. It ranges from heat cramps and heat exhaustion to heat stroke, which is a medical emergency.
Heat stroke can cause high body temperature, confusion, loss of consciousness, and even death if not treated immediately.
Who is most at risk
Certain groups are more vulnerable to dehydration and heat illness. These include children, elderly individuals, people with chronic illnesses, and those working outdoors.
People with conditions such as diabetes and kidney disease are also at higher risk, as dehydration can worsen these conditions.
Common mistakes people make
Many people wait until they feel thirsty before drinking water. However, thirst is often a late sign of dehydration. Others replace water with sugary drinks or alcohol, which can worsen dehydration.
Wearing heavy clothing, working long hours in the sun without breaks, and ignoring early symptoms also increased risk.
Prevention: Simple but powerful steps
Preventing dehydration is straightforward. Drinking water regularly throughout the day is the most important step. People working outdoors should take frequent breaks in shaded or cool areas.
Light clothing, avoiding peak sun hours, and increasing fluid intake during illness or physical activity are also important measures.
Electrolyte replacement may be helpful during prolonged sweating, but water should always be the primary source of hydration.
The role of employers and communities
Workplaces and communities play an important role in prevention. Employers should ensure access to drinking water, provide shaded rest areas, and encourage regular breaks for workers.
Schools and community groups can also promote hydration awareness, especially among children and young adults.
Why this matters for health
Dehydration not only causes immediate symptoms, but can also affect long-term health. Repeated dehydration has been linked to kidney problems and reduced physical performance.
In a country like Guyana, where heat exposure is constant, addressing hydration is essential for maintaining overall health.
Dehydration is common, preventable, and often ignored. In a hot climate, it can quickly become dangerous.
Do not wait until you feel thirsty. Drink water regularly, take breaks from the heat, and recognise the warning signs early.
Stay hydrated. Stay safe. Protect your health.
