Impact Of Heat Wave On Brain And Nervous System: Neurologist Shares Key Signs And Safety Measures

With a heat wave sweeping the country, it is important to take the necessary precautions to stay safe. Read on to know what our neurologist says.

Temperatures across North India are increasing, and New Delhi recorded a maximum temperature of 47.4 degrees Celsius on Monday. Severe heatwave red alert has been issued by the India Meteorological Department (IMD) Haryana, Chandigarh, and Delhi for the next five days. In such a scenario, heat stroke or sunstroke is a very real possibility. This is a serious condition characterized by a body temperature exceeding 104 degrees Fahrenheit (40 degrees Celsius). It typically arises from prolonged exposure to high temperatures and excessive physical exertion, especially in hot weather. Vulnerable populations, such as newborns and the elderly, are particularly susceptible. As the summer sun reaches its peak, the risk of heat stroke escalates, posing severe threats like brain damage, organ failure, and mortality.

Here, let us see how you can save yourself from this threat. But first, you need to know about this condition.

Risk Factors Of Heat Strike

Several factors can precipitate heat stroke, including -

Types Of Heat Strokes

Heat stroke manifests in two forms exertional and non-exertional. Exertional heatstroke typically occurs when individuals overexert themselves in hot conditions and can develop rapidly, within hours. Non-exertional heatstroke, on the other hand, is more common, often emerging gradually due to age or underlying health issues, sometimes taking several days to manifest fully.

Signs and symptoms of heat stroke

Recognizing the signs of heat stroke is crucial. These include

Dry skin
Rapid breathing
Fluctuating blood pressure
Nausea
Vomiting
Loss of consciousness.

Excessive sweating may also precede a heat stroke episode.

Heat Stroke Complications

Untreated, heat stroke can lead to complications such as

Reduced blood flow to the heart
Circulatory issues
Brain swelling
Nerve damage.
Heat waves can also exacerbate migraines, with studies suggesting a strong correlation between temperature spikes and migraine onset.
Environmental factors, including serotonin level fluctuations induced by weather changes, contribute to this phenomenon. Prolonged exposure to high temperatures increases the risk of heat exhaustion, a precursor to heat stroke.

Risk For Alzheimer's Patients

Moreover, heat waves pose particular risks to individuals with Alzheimer's disease.

Hospitalization rates and post-discharge mortality among Alzheimer's patients surge during heatwaves.
Impaired judgment and decision-making abilities in Alzheimer's patients exacerbate vulnerability to heat-related illnesses.
Coexisting conditions like diabetes and heart disease further compound these risks.

As global temperatures rise, it becomes imperative to take proactive measures to safeguard vulnerable populations.

Keep Yourself Safe: Try These Home Remedies

Home remedies and safety precautions can mitigate the impact of heat waves.

Essential oils like lavender or peppermint, cold compresses will offer relief
Keep yourself hydrated with beverages like herbal tea, lemon water, coconut water, and buttermilk.
Keep your environment cool
Consume electrolyte-rich fluids
Wear light, loose clothing
Cold water baths can aid in reducing body temperature
Avoid strenuous physical activity during peak heat hours minimizes heat stroke risk.

Be Aware Of, Be Vigilant Against Heat Stroke

Understanding the ramifications of heat waves on the brain and overall health is paramount. By implementing preventive measures, staying vigilant for warning signs, and prioritizing hydration and cooling strategies, individuals can mitigate the adverse effects of heat stroke and safeguard their well-being during sweltering weather conditions.
