Migraine in the summer
Summer Migraine Problem: As temperatures rise and lifestyles change, the problems of people suffering from migraines also increase. According to doctors, migraine is a year-round neurological problem. However, the number and intensity of attacks increase in summer. This is not directly due to the heat, but rather the increased triggers of this season. According to neurologists, people who already have migraines experience more frequent attacks during the summer. This is due to environmental and lifestyle factors that become difficult to control during this season. So, let us tell you today why migraine cases increase in summer and what you can do to prevent it.
Dehydration becomes a major cause
In summer , we lose more water through sweat, leading to dehydration, which is considered a major trigger for migraines. Lack of water in the body affects blood flow and brain function, which can trigger headaches. Even mild dehydration can trigger an attack in susceptible individuals.
Bright sunlight and light increase the problem.
Bright sunlight and its glare can worsen migraine headaches. Prolonged exposure to sunlight can strain the eyes and brain, leading to headaches. Staying outside during the afternoon, especially, increases the risk.
Changing lifestyle is also responsible
People's daily routines often change during the summer. Staying up late, skipping meals, traveling, and fatigue can all trigger migraines. Lack of sleep, an empty stomach, and excessive fatigue can worsen an attack.
People living in cities are more at risk.
People living in urban areas may be at greater risk for migraines. Concrete and pollution can cause higher temperatures in cities, putting extra strain on the body and increasing triggers. Migraines aren't just a simple headache; they can also include symptoms like throbbing pain on one side of the head, nausea, vomiting, discomfort from bright light and sound, dizziness, and fatigue. In many cases, the pain can last from several hours to two to three days.
What to do for protection?
To prevent migraines in the summer, try to drink plenty of water throughout the day. Avoid sun exposure, especially during the afternoon. Wear sunglasses or a protective head covering when outdoors. Eat a balanced diet on time, get 7 to 8 hours of sleep daily, and avoid excessive fatigue and overheating. Furthermore, if migraine attacks become more frequent, the pain becomes more severe, or begins to interfere with daily life, it's important to consult a doctor.
