Loo is a term commonly used in India and other South Asian countries to describe the hot, dry winds that blow during summer, particularly in regions with extreme heat. These winds, combined with high temperatures, can lead to heat-related illnesses, including heat exhaustion and heat stroke. Exposure to the loo for prolonged periods can be dangerous, especially for children, the elderly, and people with pre-existing health conditions.
Understanding the symptoms of loo-related illnesses is crucial to preventing severe health complications. In this blog, we will explore the symptoms of loo, its impact on the body, prevention tips, and when to seek medical help.
What is Loo and How Does It Affect the Body?
Loo winds are hot and dry winds that sweep across northern and western India, particularly during the summer months of April to June. These winds raise temperatures significantly, often crossing 45°C (113°F) or higher, making it extremely difficult for the body to cool down naturally.
Since loo winds are dry, they absorb moisture from the environment, including the human body, leading to rapid dehydration. This can cause heat exhaustion or heat stroke, which are serious medical conditions that require immediate attention.
Common Symptoms of Loo Exposure
Extreme Body Heat and High Fever
One of the earliest signs of loo exposure is a rapid increase in body temperature. As the body absorbs heat from the environment and struggles to cool down, a high fever (above 101°F or 38.5°C) may develop.
Excessive Thirst and Dehydration
Loo causes rapid fluid loss through sweating, leading to severe thirst, dry mouth, and reduced urination. Dark yellow urine is a clear indicator of dehydration, signalling the need for immediate fluid intake.
Weakness, Fatigue, and Dizziness
Continuous exposure to hot winds can cause weakness and dizziness due to fluid and electrolyte loss. People often feel lightheaded or faint after prolonged exposure to the loo, especially if they have not consumed enough water.
Nausea and Vomiting
As body temperature rises, the digestive system becomes affected, leading to nausea and vomiting. This further accelerates dehydration and electrolyte imbalance, making the condition more dangerous.
Headache and Disorientation
Persistent headaches are common after exposure to the loo, caused by dehydration and overheating of the brain. In severe cases, people may experience confusion, trouble concentrating, or disorientation.
Hot, Dry Skin with No Sweating
In cases of heat stroke due to loo, the body’s cooling mechanism shuts down, leading to hot, dry skin with little to no sweating. This is a medical emergency that requires immediate intervention.
Rapid Heartbeat and Breathing Difficulties
As the body struggles to maintain normal functions, heart rate increases to circulate blood and keep organs functioning. In severe cases, rapid breathing or shortness of breath may occur, indicating serious heat-related stress on the body.
Muscle Cramps and Weakness
Due to excessive sweating, the body loses essential minerals like sodium and potassium, which are needed for proper muscle function. This can result in painful muscle cramps, weakness, and overall fatigue.
Loss of Consciousness or Seizures
Severe cases of heat stroke caused by loo can lead to fainting or even seizures. This occurs when the body is unable to regulate its temperature, affecting brain function and leading to loss of consciousness.
When to Seek Medical Help?
While mild cases of loo-related illness can be managed at home with proper hydration and rest, medical attention is required if:
Fever persists above 103°F (39.4°C) and does not respond to cooling measures
The person stops sweating despite feeling extremely hot
Symptoms like confusion, dizziness, or fainting occur
Nausea and vomiting prevent the person from drinking fluids
There is difficulty breathing or a rapid, irregular heartbeat
Severe cases of heat-related illnesses can lead to organ failure or life-threatening complications if left untreated.
