Why do I often have headaches and fevers?

Frequent headaches and fevers may be caused by lack of sleep, because lack of sleep will lead to a decrease in metabolism and blood circulation, and staying up late for a long time will lead to neurasthenia, which will cause headaches and fever. Therefore, everyone should learn to relax and adjust their work and rest time, and adjust their diet in normal times. Now let us understand the causes of frequent headaches and fevers.

1. Lack of sleep

A normal and regular work and rest habit allows the brain to get sufficient rest. On the contrary, lack of sleep will not only affect the rate of metabolism and blood circulation, but also interfere with the brain's rest. Therefore, frequent staying up late or long-term insomnia will cause frequent headache symptoms.

2. Mental stress

The human brain is a fragile organ that is particularly susceptible to external stimuli. Excessive stress or tension can easily cause people to fall into negative emotions such as anxiety, irritability, and depression. These negative emotions will stimulate the brain nerves, making them overly tense and causing uncomfortable symptoms such as frequent headaches.

3. Dietary factors

Unhealthy eating habits can easily induce frequent headaches. For example, coffee is a food that has a nerve-stimulating effect. Although it can refresh the mind, drinking too much coffee will stimulate the nerve center and cause vasodilation, which will then produce the uncomfortable symptoms of headaches. In addition, foods such as alcohol and ice cream are also the culprits of frequent headaches.

4. Physical reasons

Common physical factors such as brain vasodilation, changes in intracranial pressure, and tumor compression can stimulate brain nerves and induce headache symptoms.

5. Facial diseases

The five senses of the human body are closest to our brain, so once the eyes, ears, mouth, nose, and throat are diseased, it is easy to stimulate the brain's nerve tissue and cause referred or reflex headaches. In addition, spasm and contraction of the cervical muscles caused by neck lumps, inflammation, etc. can also stimulate the brain.

6. Infection

There is a wealth of pain-sensitive tissue on the meninges of the brain. If the brain is infected, the pain-sensitive tissue will secrete inflammatory substances, leading to brain edema and excessive stretching of the meninges and blood vessels, eventually causing headache symptoms, such as common meningitis, brain abscess, infectious pneumonia, etc.

7. Intracranial and extracranial trauma

If the brain has been severely injured, it is easy to have symptoms of frequent headaches. For example, cerebral contusion, concussion, etc. will damage brain health and cause sequelae such as headaches and dizziness.

8. Poisoning

Toxic substances such as organophosphorus, carbon monoxide, formaldehyde, and salicylic acid drugs in our daily lives can easily damage cells and tissues in the brain, causing sequelae such as headaches.

9. Systemic diseases

Many systemic diseases accompanied by fever symptoms can cause frequent headaches. This is because fever inflammatory factors increase blood flow and metabolic rate in the brain, such as inflammation such as nephritis, pneumonia, or common cold fever. In addition, high blood pressure can change the pressure difference in the brain and cause abnormal vasoconstriction and dilation, while acute heart failure can affect the blood oxygen supply to the brain. These diseases can cause frequent headaches and usually require diagnosis in combination with other typical symptoms.
