Higher temperatures can disrupt ecosystems, impacting plant and animal life, and can also cause stress on agricultural crops and water resources.

Moreover, extreme heat can contribute to the intensification of wildfires, accelerate glacial melting, and influence ocean temperatures, influencing weather patterns and contributing to the overall impact of climate change. As global temperatures continue to rise, understanding and mitigating the effects of extreme heat on the environment becomes crucial for safeguarding ecosystems and promoting climate resilience.

The impact of Heat Exhaustion and Heat Stroke

The Signs and Symptoms of Extreme Heat

Heat Exhaustion Consequences: Heat exhaustion occurs when the body becomes dehydrated and loses essential electrolytes due to prolonged exposure to high temperatures and excessive sweating. If not addressed promptly, it can lead to various consequences, such as:

• • Dehydration: Severe loss of fluids can cause dehydration, leading to symptoms like dry mouth, fatigue, and reduced urine output.
  • Heat Cramps: Muscle cramps and spasms can result from electrolyte imbalances due to sweating, causing pain and discomfort.
  • Heat Rash: In some cases, heat exhaustion can lead to the development of heat rash, characterized by red, itchy skin with small blisters.

Heatstroke Consequences: Heatstroke is a life-threatening condition that occurs when the body’s internal temperature regulation system fails, and the core body temperature rises to dangerously high levels. The consequences of heatstroke are far more severe and can include:

• • Organ Failure: As the body temperature rises above 104°F (40°C) or higher, vital organs such as the brain, heart, kidneys, and liver can be damaged, leading to organ failure.
  • Brain Damage: Heatstroke can cause neurological effects, including confusion, delirium, seizures, and loss of consciousness. If not treated immediately, it can result in long-term brain damage.
  • Multiple Organ Dysfunction Syndrome (MODS): Heatstroke can lead to a condition known as MODS, where multiple organs fail simultaneously, resulting in a life-threatening medical emergency.
  • Coma and Death: In the most severe cases, untreated heatstroke can lead to a coma or death.

Long-Term Effects: Even for those who survive heatstroke, there can be lasting consequences. Depending on the severity and promptness of medical intervention, individuals may experience long-term cognitive impairments, memory issues, and difficulties in concentration.

To mitigate the consequences of heat exhaustion and heatstroke, it is crucial to take preventive measures during extreme heat conditions. Staying well-hydrated, avoiding strenuous activities during the hottest parts of the day, seeking shade, and wearing appropriate clothing are essential. If someone shows signs of heat-related illnesses, it’s vital to move them to a cool place, provide water, and seek medical attention immediately. Heat exhaustion can be reversed with proper care, but heatstroke requires urgent medical intervention and hospitalisation to prevent severe complications or fatalities. Awareness and proactive measures can go a long way in safeguarding individuals from the adverse effects of extreme heat.

Hydration Nation: The Importance of Drinking Water During Heatwaves

During heatwaves, all you need to know about extreme heat is knowing the body’s natural cooling system through sweating goes into overdrive, causing rapid fluid loss. This can result in symptoms like dry mouth, dizziness, fatigue, and dark-coloured urine. As dehydration progresses, more severe consequences may arise, such as heat cramps, heat exhaustion, and even life-threatening heatstroke.

To combat dehydration and protect ourselves during heatwaves, it’s vital to prioritise hydration. Here are some practical tips to stay hydrated in extreme heat:

1. Drink Plenty of Water: Make it a habit to drink water regularly throughout the day, even if you don’t feel thirsty. Aim for at least eight 8-ounce glasses of water daily, or more if you’re physically active or sweating heavily.
2. Hydrate Before, During, and After Physical Activity: If you’re engaging in outdoor activities or exercising, ensure you’re well-hydrated before starting and continue to drink water at regular intervals during the activity.
3. Avoid Dehydrating Beverages: Limit the consumption of dehydrating drinks like alcohol, caffeine, and sugary beverages, as they can contribute to fluid loss.
4. Eat Hydrating Foods: Incorporate fruits and vegetables with high water content into your diet, such as watermelon, cucumbers, oranges, and strawberries.
5. Carry a Reusable Water Bottle: Keep a reusable water bottle with you at all times, so you can easily sip water throughout the day.
6. Set Hydration Reminders: Use smartphone apps or alarms to remind yourself to drink water regularly, especially if you have a busy schedule.
7. Monitor Urine Colour: Check the colour of your urine as an indicator of hydration. Light-coloured urine generally signifies good hydration, while dark-coloured urine may indicate dehydration.
