As rising temperatures grip parts of India, the India Meteorological Department has issued a heatwave advisory, prompting health experts to warn about an increase in migraine cases during the summer months. Medical professionals highlight that understanding triggers and taking preventive steps can significantly reduce the frequency and intensity of these episodes.
Migraine, a neurological condition, is more than just a regular headache. It often presents as intense throbbing pain on one side of the head and may be accompanied by nausea, sensitivity to light, and discomfort with movement. During summer, this condition tends to worsen due to the body’s response to heat.
According to medical insights, rising temperatures force the body to regulate heat through a process known as vasodilation. This causes blood vessels in the brain to expand, which can activate sensitive nerve endings and trigger migraine pain in individuals who are prone to it.
Dehydration is another major contributor. Even a slight drop in hydration levels can affect brain tissues and stimulate pain receptors, increasing the likelihood of headaches. Additionally, exposure to intense sunlight—especially during peak afternoon hours—can overstimulate the brain’s visual centers, further intensifying symptoms.
Other factors such as poor sleep due to hot nights and irregular eating patterns can combine with heat exposure, creating a cumulative effect that leads to more severe migraine attacks.
It is also important to distinguish between a migraine and a dehydration headache. Migraines often begin with early warning signs like fatigue, mood changes, neck stiffness, or cravings before progressing to pulsating pain, usually on one side of the head. In contrast, dehydration headaches are typically mild, affect both sides of the head, and improve quickly after fluid intake.
Managing a migraine requires more than just drinking water. Experts recommend resting in a cool, dark, and quiet environment, followed by proper hydration with water or electrolyte solutions. Medications such as Triptans are most effective when taken early, while Naproxen sodium is commonly used as an initial treatment option.
To prevent heat-induced migraines, doctors suggest maintaining proper hydration by consuming 2.5 to 3 litres of water daily, avoiding outdoor exposure during peak heat hours, eating light and regular meals, including water-rich foods like watermelon in the diet, wearing protective clothing, and following a consistent sleep routine.
Medical attention should be sought immediately if a headache is sudden and severe or accompanied by symptoms like fever, confusion, or neck stiffness, as these may indicate a more serious condition.
