New Delhi. In this scorching heat, if you are having frequent headaches and you are ignoring it considering it to be fatigue or lack of sleep, then it could be a big mistake of yours. According to Dr. Bhaskar Shukla, Consultant Neurologist, PSRI Hospital, New Delhi, the continuously increasing temperature and heatwave are directly attacking our brain and we ignore its signs every day. Oxygen does not reach the brain, this is the root cause of headache. When it is extremely hot outside, the body has to work extra hard to keep itself cool and in this process, the body starts losing water rapidly. The first and direct victim of dehydration is our brain. Due to lack of water, blood flow and sufficient oxygen does not reach the brain, due to which problems like feeling heavy, dizziness and constant headache start. Heat wave is becoming the biggest trigger of migraine. Doctor Bhaskar Shukla explains that heat affects not only the body but also the mental state. Humidity and bright sunlight increase irritability, make it difficult to concentrate and cause fatigue quickly. This mental pressure makes the headache worse. Especially for migraine patients, heatwave acts as a dangerous trigger and a tremendous increase in the number of migraine attacks is seen during summer days. Imbalance of electrolytes is also a big danger. Due to prolonged exposure to strong sunlight and drinking less water, the essential minerals of the body are released through sweat, due to which the balance of electrolytes gets disturbed. This imbalance is a major cause of headache. Laborers working in the sun, travelers traveling long distances and children playing outside are most at risk of this danger. Keep yourself safe with these simple measures. Doctors advise to drink enough water throughout the day and avoid dehydration. While going out in the sun, cover your head with a cap, cloth or umbrella. Instead of eating heavy and heavy food, eat light and cooling food and avoid going out in the hot afternoon sun as much as possible. Do not ignore these symptoms even by mistake. Doctor Bhaskar Shukla warns that if you are feeling weakness, dizziness or vomiting along with frequent headache, then it can be a sign of heatstroke and it is important to immediately consult a doctor. These body signals in summer indicate that the heatwave has now reached your brain. Timely caution is the biggest weapon to prevent this.
