Introduction

Frequent head injuries can adversely affect the brain, leading to conditions such as concussion—manifesting as chronic dizziness, insomnia, anxiety, or headache. They may also cause intracranial hematoma, resulting in symptoms like headache, dizziness, or even coma. Additionally, such injuries can lead to epidural hematoma or cerebral contusion and laceration, causing necrosis of neurons within the brain parenchyma and subsequently resulting in delayed limb movement, numbness, and pain.

Frequent head impacts can affect the brain by causing concussion, intracranial hematoma, or cerebral contusion and laceration. Specific effects are as follows:

1. Concussion

If the head is frequently bumped with relatively mild force, it may result in scalp hematoma or mild symptoms of concussion, such as chronic dizziness, insomnia, anxiety, or headaches.

2. Intracranial Hematoma

Frequent head impacts with greater force may lead to intracranial hematoma. If the hematoma is large, it can compress surrounding nerves or blood vessels, easily causing symptoms like headache and dizziness. In severe cases, it may even lead to unconsciousness.

3. Cerebral Contusion and Laceration

If frequent head impacts cause serious brain injury, conditions such as epidural hematoma or cerebral contusion and laceration may occur. This can lead to necrosis of brain parenchymal nerve cells, resulting in symptoms including delayed limb movement, numbness and pain, or decreased intelligence.

The head is a vital part of the human body. Frequent head injuries can easily damage the brain; therefore, it is important to protect the head during daily activities. If any discomfort in the head occurs, prompt medical evaluation and treatment according to medical advice are recommended.

What should I do if pimples appear on my forehead from staying up late?

Frequent late-night sleeping leading to forehead acne can be managed by adjusting one’s sleep schedule, combined with oral and topical medications. Individuals who regularly stay up late often experience compensatory sebum overproduction in the facial skin, which can trigger acne. It is recommended to avoid frequent late-night sleeping and instead adopt a regular sleep-wake cycle—going to bed early and rising early. As facial sebum production decreases, acne typically ceases to worsen progressively.

I hit my forehead and got a big bump—why are my eyes turning purple and blue?

After a forehead impact causing a large bump and purple bruising around the eyes, the condition is usually due to a subcutaneous hematoma on the forehead with blood spreading to the outer area of the eyelids, resulting in periorbital ecchymosis (black eye). This typically indicates the dispersion of accumulated blood. Patients with a forehead bump and bruised eyes can apply warm compresses using warm towels, hot water bags, or salt bags. However, if the injury occurred less than 24 hours ago, cold compresses are recommended instead.

How to reduce swelling from a head bump

If a patient's head swelling after a bump is not severe, symptoms can be relieved with general treatment. It is recommended that the patient apply a cold compress to the affected area within 24 hours of injury by wrapping an ice pack in a towel to prevent enlargement of the hematoma. If significant swelling persists beyond 24 hours, apply a warm towel to the affected area to promote faster resolution of the hematoma.

What should I do if my head hit something and now there's a bump?

In general, a bump on the head caused by minor impact can be treated through conservative management, physical therapy, or medication.
