How to relieve headache after COVID-19 infection

COVID-19 infection usually refers to infection with the novel coronavirus. In general, headache following a novel coronavirus infection may be caused by viral invasion of the nervous system, sleep deprivation, cold exposure, fever, or medication-related factors. Patients should promptly seek medical attention at a正规 hospital to determine the underlying cause and receive appropriate treatment, which may include oral medications, adequate rest, staying warm, or adjusting medications. Specific causes are analyzed as follows:

1. Viral invasion of the nervous system: After infection with the novel coronavirus, the virus may infect the upper respiratory tract and subsequently invade the nervous system—including both the central and peripheral nervous systems—triggering neuroinflammatory responses that lead to headache. Patients can be treated with medications such as Lianhua Qingwen Capsules, Xiao Chai Hu Granules, or Antiviral Oral Liquid.

2. Sleep deprivation: During illness, patients may experience insufficient sleep due to physical discomfort, anxiety, or other factors. Lack of adequate sleep can impair normal nervous system function, leading to or worsening headaches. In such cases, patients should adjust their lifestyle, avoid strenuous exercise, and maintain a balanced and nutritious diet.

3. Cold exposure: During infection, the immune system may be hyperactive due to viral attack, reducing the body's ability to adapt to external environmental changes. If patients are exposed to cold environments during infection, it may cause blood vessel constriction and poor circulation, potentially triggering headaches. It is important to maintain a comfortable ambient temperature and ensure proper warmth when going outdoors.

4. Fever: Fever is one of the common symptoms of novel coronavirus infection. When body temperature rises, blood vessels dilate and cerebral blood flow increases, which may sometimes result in headaches. Patients may take medications such as acetaminophen tablets, ibuprofen tablets, or Compound Liquorice Tablets under medical guidance to relieve symptoms.

5. Medication factors: Following novel coronavirus infection, patients often require medication to manage symptoms. However, improper use of medications or drug allergies may lead to adverse effects such as headache. In such cases, it is recommended to adjust the treatment regimen under a doctor’s supervision to prevent worsening headaches and interference with recovery.

In daily life, individuals should maintain healthy habits, follow a regular作息 schedule, and ensure sufficient sleep to support normal physiological function. Additionally, regular physical exercise should be encouraged to enhance overall immunity.
