What causes headaches in summer?

The weather is hot in the summer, and the hot and humid environment will make people feel very uncomfortable, which is also an important cause of headaches. What we should be vigilant about is heatstroke. When heatstroke occurs, it often causes symptoms such as nausea and headache. At this time, you should replenish water in time, because if the body is dehydrated, it often causes headaches. In addition, some patients with migraines will have more severe headaches in the summer.

What causes headaches in summer?

1. Dehydration headache

The temperature in summer is often higher than human body temperature, so more sweat evaporates. If water is not replenished in time, the body will easily become dehydrated. When the human body is dehydrated, the cerebrospinal fluid decreases and the gap between the skull and brain tissue increases. When the body position changes, especially when standing, the brain tissue "sinks" or "vibrates" slightly, causing the nerve roots and blood vessels in the brain to be pulled and headache symptoms occur. For this type of headache caused by dehydration, a certain amount of saline solution can be infused to eliminate or reduce dehydration. At the same time, the patient should rest in bed without using a pillow to keep the head low. The key to preventing this type of headache is to stay hydrated. Diarrhea is more likely to occur in summer, so you should prevent dehydration when you have diarrhea. Otherwise, dehydration headaches are likely to occur.

2. Summer headache

Some people will often suffer from headaches accompanied by loss of appetite, low fever and general fatigue in the summer, especially in early summer when the temperature rises suddenly and in the hot summer when the temperature exceeds 37 degrees Celsius. The disease will heal immediately after autumn comes and the weather gets cooler. This type of headache is called summer headache, which is caused by autonomic nervous system dysfunction and mostly occurs in people who are weak and have insufficient qi and blood. The preventive measures mainly include paying attention to cooling down the environment, ensuring a certain amount of sleep, eating a light diet, and eating more vegetables and fruits.

3. Migraine is also called vascular headache.

Severe head pain occurs due to paroxysmal vasomotor dysfunction of intracranial and extracranial blood vessels. The pain can be unilateral or bilateral, and is accompanied by symptoms of autonomic dysfunction such as pale complexion, nausea, and vomiting. Some patients have visual symptoms about 30 minutes before the onset of headache, namely photopsia, such as flashing dark spots or "golden stars in front of the eyes". To reduce the occurrence of migraines, special attention should be paid to combining work and rest, getting enough sleep, and avoiding anxiety and tension in the summer.

4. Ice cream headache pain

It is often located in the middle of the skull, sometimes on the temporal side, frontal area or posterior orbital region, and manifests as momentary stabbing pain or unbearable pain. It is worth noting that frequent attacks of this type of headache can easily lead to vascular disorders. Therefore, people with a history of headaches should eat less cold drinks. When eating cold drinks, be careful to keep your palate away from cold food as much as possible to effectively prevent the occurrence of "ice cream headache". Generally, do not consume frozen food or drinks quickly. People with a history of headaches or "ice cream headaches" should eat less cold drinks. Once the "ice cream headache" occurs, you can repeatedly perform local massage with your hands to relieve the contraction of blood vessels and muscles in the head caused by sudden cold stimulation and reduce pain. If the headache is particularly severe, you can take painkillers under the guidance of a doctor.
