On extremely hot days, one can experience significant headaches, particularly at certain times. What is the reason behind these headaches that appear specifically when exposed to high temperatures? Whether it is due to heat stroke, dehydration, or any other reason, it is essential to primarily ensure a reduction in body temperature. Excessive heat is considered a trigger for headaches, as rising temperatures cause blood vessels to dilate, leading to migraines. Therefore, for those who are already prone to migraines, the likelihood of experiencing this condition increases on very hot days.
Additionally, sunlight enhances the chances of experiencing migraines or tension-related headaches. This increases sensitivity to light, which is a symptom of migraines, according to a publication in Sante Magazine. Therefore, on hotter days, it is best for those who already experience migraines or are more susceptible to them to stay in a cool place and wear sunglasses when going outside.
### What to Do When Facing a Migraine on Hot Days?
Instead of letting the pain gradually increase, it is important to take anti-inflammatory medications at the right time, as they are highly effective. If this condition recurs, there are specific medications for it, which act directly on dilated blood vessels.
It is worth noting that if headaches occur during the day, it could be due to a sunstroke resulting from excessive exposure to its rays without protection, such as a hat or staying under a shade. At times, such a condition could lead to death. It disrupts brain function, preventing it from regulating body temperature due to sweating. This condition may cause headaches and severe heat sensations, especially with facial redness, nausea, or vomiting, in addition to occasionally rising temperatures. In more advanced cases, it may be accompanied by shivering, heart rhythm disturbances, and loss of consciousness, as well as dehydration and intense thirst.
### What Should Be Done in Case of Sunstroke?
It is essential to act swiftly in such cases by moving to an air-conditioned room or a well-ventilated and cool area, and it is necessary to consume a drink containing sugar. This will help lower body temperature. A damp cloth on the face can also be used.
However, if symptoms related to the nervous system arise, such as shivering, or if there are heart rhythm irregularities or other types of discomfort, one should go directly to the hospital.
In all cases, keeping the body hydrated and drinking plenty of water are fundamental steps that must be employed to avoid problems that can occur on extremely hot days. If the temperature is high, it is advisable to drink up to 3 liters of water a day, which is about a cup of water each hour.
