Don't be subjective with headaches when the weather changes

Weather headaches often occur in people who are sensitive to changes in temperature, humidity, air pressure . Not to mention, weather also affects the body's dehydration, stress, insomnia . makes headaches easier or recurrent, becoming a chronic headache.

Although there are no specific statistics in Vietnam, every time the weather changes, the number of people who come to see a neurologist because of a headache increases significantly, in which there are two basic types of headaches that are painful. both head or migraine.

Professor, Dr. Nguyen Van Thong, chairman of the Association for Prevention of Northern Stroke - Chairman of the Department of Neurology YDLS108 Research Institute, said many people come to the hospital with very similar symptoms such as frequent aches and pains. dull head, numbness or severe pain, dizziness; The pain also spreads to the eye sockets, the nose . every time the hot sun changes to rain or wind or is going outdoors in the air-conditioned room, early or late bathing, traveling in other climates causing much trouble in work, life.

Headaches are symptoms of brain dysfunction, an increased risk of stroke.

When having a headache due to weather, many people often think that this is a transient symptom, self-end and not worrying. However, according to Professor Nguyen Van Thong, headache when the weather changes is also a sign that brain activity is disturbed, especially cerebrovascular lesions such as atherosclerosis, cerebral anemia.

This process of injury is closely related to the increase of free radicals - harmful substances produced during the body's metabolism and external effects such as stress, insomnia . promote formation. atheroma, hinders blood to the brain.

When the "resonance" from the weather will cause blood vessels to become more congested, change the viscosity of blood and intermediate chemicals in the brain, leading to vasomotor disorders, causing brain vessels to expand, abnormal changes, causing headaches, migraines.

40% of strokes are directly related to headaches , according to research by the Royal College of Medicine in London. In particular, this risk increases greatly when the weather is hot and cold suddenly causing arteries to cause blood to get stuck in the brain, causing severe brain death due to lack of oxygen and nutrients or peripheral resistance increases causing rupture, rupture of cerebral vessels causing stroke. Therefore, pay attention to the risk of a near stroke in people with headaches, especially those with chronic headaches.

According to Associate Professor, Dr. Vu Anh Nhi, Chairman of Ho Chi Minh City Neurology Association, when headaches start or increase due to weather changes, patients often endure or believe in word of mouth. , "thanks to" pain relievers to relieve.

However, mechanical effects such as massage, massage or shaving are only for dealing with acute headaches, cannot interfere deeply when the blood vessels are damaged. The habit of abuse of potential painkillers has many health risks because of the loss of early warning signs of cerebrovascular lesions, especially the stroke from headache.

Modern medicine emphasizes prevention and improvement of headaches must go from the root by fighting free radicals, while strengthening the body's natural defense system in the brain.
