According to a recent research, the symptoms of several brain disorders are getting worse due to climate change. A number of illnesses, including stroke, migraines, meningitis, epilepsy, multiple sclerosis, schizophrenia, Alzheimer’s disease, and Parkinson’s, can get worse with rising temperatures and humidity levels.
The ability to cope with environmental obstacles, particularly elevated temperatures and humidity, is attributed to our brains. They make us start perspiring and advise us to seek shade and get out of the sun.
Our brain’s billions of neurons are each like a multi-component, electrically active computer that is constantly learning and changing. Since many of these parts are made to function together only in a limited temperature range, their rates of operation vary based on the outside temperature. We have evolved over millennia to live within these boundaries, and our bodies and all of their parts function well inside them.
Waves of heat disrupt sleep
Originating in Africa, humans typically prefer temperatures between 20˚ and 26˚C and humidity levels between 20 and 80 percent. Since many of the parts of the brain operate at the upper limits of their temperature tolerances, even slight variations in humidity or temperature can lead them to malfunction.
Our brain finds it difficult to control our body temperature and starts to malfunction when those environmental variables quickly shift into unaccustomed ranges, as is the case with severe temperatures and humidity linked to climate change.
Sweat is necessary for staying cool or for alerting us when we are too hot, and certain illnesses can already interfere with it. Certain medications used to treat neurological and psychiatric disorders make matters worse by impairing the body’s capacity to respond, which can cause perspiration to decrease or interfere with the brain’s mechanisms for regulating body temperature.
Waves of heat exacerbate these consequences. For instance, heat waves exacerbate disorders like epilepsy by interfering with sleep. Multiple sclerosis sufferers may experience worsening symptoms in the summer because heat waves can exacerbate brain wiring defects. As a result of dehydration during heat waves, higher temperatures can cause the blood to thicken and clot more easily, which can result in strokes.
Rises in hospital admission rates
It follows that many persons with neurological illnesses will be impacted by climate change, frequently in a variety of ways. As the temperature rises, more people are being admitted to hospitals with dementia. Improved management of seizures can lead to epilepsy, worsening symptoms in multiple sclerosis, and an increase in the frequency and number of stroke-related deaths. Additionally, a number of prevalent and dangerous mental illnesses, like schizophrenia, get worse and require more hospital admissions.
Approximately 20 percent of the additional deaths during the 2003 European heatwave were neurological disorders.
Neurological problems can be made worse by unseasonal local temperature extremes, larger-than-usual temperature changes during the day, and unfavorable weather events including heatwaves, storms, and floods. These repercussions are further complicated by specific conditions. For example, the heating effect of urban surroundings and a dearth of green spaces can exacerbate the negative effects of a heatwave on mental and neurological illnesses.
There are a great number of people worldwide who suffer from neurological and psychiatric disorders that could be negatively impacted by climate change. Around 60 million people worldwide suffer from epilepsy. Approximately 55 million individuals worldwide suffer from dementia, with more than 60% residing in low- and middle-income nations. By the year 2050, these figures will rise to more than 150 million as the world’s population ages. Globally, stroke is the second-leading cause of death and a major contributor to disability.
Extending assistance
It is obvious that addressing climate change as a whole is necessary. We urgently need mitigation measures spearheaded by states working together on an international level. However, years will pass before significant efforts yield noticeable results. In the interim, we can support those suffering from neurological disorders by offering customized information regarding the dangers of inclement weather and severe temperatures.
Experts in public health and medicine can provide guidance on lowering those risks. Neurological illnesses can be adapted to local weather-health alert systems. In order to make that weather-health alerts and interventions make sense for impacted populations and can be implemented, we can also collaborate with persons who are affected, their families, and caregivers.
The gains of scientific discoveries are at risk of disappearing unless we begin tackling climate change as part of neurological treatment. Most significant, neurological illnesses provide information about what might happen to a healthy brain that is pushed past its evolutionary boundaries and its ability to adapt behaviorally.
The likelihood of this happening increases with our inability to address climate change. We need to take action against climate change and pay closer attention to the feeling that the temperature is rising too high if we are to continue living the lives we desire. Our brains are essential to us, and climate change is terrible for them.
