Before heat stroke fully develops, your body often signals distress through various symptoms that should not be ignored. These signs, commonly linked to heat exhaustion, serve as a critical warning that immediate action is needed.

• Heavy Sweating: Initially, the body responds to overheating by producing excessive sweat in an effort to cool down. However, as dehydration sets in, sweating may decrease, which is a serious indicator.
  
  
• Dizziness and Weakness: As your body struggles to regulate its temperature, blood flow to the brain decreases, leading to dizziness, lightheadedness, and an overall feeling of weakness. This can be accompanied by nausea or vomiting, further signaling that the body is overwhelmed by the heat.
  
  
• Headache and Muscle Cramps: A throbbing headache often develops as dehydration progresses. Muscle cramps, particularly in the legs, arms, or abdomen, can also occur due to the loss of essential salts and minerals through sweating. These cramps are not only painful but also a sign that your body’s electrolyte balance is being disrupted.
  
  
• Rapid Heartbeat and Breathing: The heart works harder to pump blood to the skin's surface to facilitate cooling, resulting in a faster-than-normal heartbeat. Breathing may become shallow and quick as the body tries to expel excess heat, signaling that the situation is escalating.
  
  
• Fatigue and Confusion: As the condition worsens, you may experience extreme fatigue, irritability, or confusion. This cognitive impairment is particularly dangerous, as it can prevent you from recognizing the need to take immediate action.
  
  

These are signs that your body is no longer able to effectively control the heat. Without intervention, these symptoms can quickly progress to full-blown heat stroke, which is a medical emergency. Taking immediate steps, such as moving to a cooler environment, hydrating, and resting, can help prevent the situation from worsening.
