Climate Change Worsens Symptoms of Brain Conditions

  • 20 May 2024

In May 2024, a recent review highlighted the exacerbating effect of climate change on various brain conditions as rising temperatures and humidity levels pose challenges for neurological health.

Key Points

  • Temperature and Humidity Impact: Rising temperatures and humidity affect brain functioning, exacerbating conditions such as stroke, migraines, and Alzheimer’s.
  • Neuronal Sensitivity: Each neuron operates within specific temperature ranges, making them vulnerable to climate-induced variations.
  • Evolutionary Adaptation: Human brains evolved for temperatures between 20°C to 26°C and 20% to 80% humidity, making extreme climate shifts challenging to manage.
  • Medication Challenges: Drugs used for neurological conditions can disrupt the body's ability to regulate temperature, compounding the impact of climate change.
  • Heatwave Exacerbation: Heatwaves worsen neurological symptoms, disrupt sleep patterns, and increase the risk of strokes and epilepsy seizures.
  • Global Health Impact: Neurological diseases affect millions worldwide, with climate change projected to exacerbate admissions and mortality rates.
  • Mitigation Strategies: Tailored information, weather-health alert systems, and community engagement are vital to mitigating climate-related risks for neurological patients.
