Introduction
To prevent scarring after a burn, it is important to promptly and properly treat the wound, keep the wound clean and dry, avoid infection, prevent secondary injury, and practice proper sun protection during later stages. In cases of severe burns, it is recommended to seek timely medical attention at a正规 hospital for professional care. Additionally, during the wound healing process, consuming foods rich in vitamin C and protein may help support skin tissue repair.

To minimize scarring after a burn, it is important to promptly and properly treat the wound, keep the wound clean and dry, prevent infection, avoid secondary injury to the wound, and practice proper sun protection during later stages. In cases of severe burns, prompt medical attention at a正规 hospital is recommended for professional care. Specific measures are as follows:

1. Prompt and Proper Wound Treatment

Immediately after a burn, rinse the affected area under cool running water for 15 to 20 minutes. After rinsing, gently cover the area with sterile gauze. High temperatures can destroy skin tissue; timely cooling halts ongoing thermal damage, reduces the extent of tissue necrosis, creates favorable conditions for skin repair, and lowers the likelihood of scar formation.

2. Keep the Wound Clean and Dry

Avoid exposing the wound to dirty water or dust in daily activities. Always wash hands thoroughly before changing dressings. A moist and unclean environment promotes bacterial growth. Keeping the wound clean and dry reduces the risk of infection and supports orderly regeneration of epidermal cells, preventing abnormal tissue proliferation.

3. Prevent Wound Infection

Do not squeeze blisters arbitrarily. Use medical antibacterial agents as directed by a healthcare provider. The blistered skin acts as a natural protective layer over the wound; breaking it increases the risk of infection. Infections disrupt normal tissue healing and may lead to excessive fibrous tissue growth, resulting in prominent scarring.

4. Prevent Secondary Injury to the Wound

Avoid scratching or rubbing the wound during healing. Wear loose, soft clothing. Newly formed skin is delicate, and physical irritation can damage regenerating epidermal cells, impair wound healing, and promote scar formation.

5. Practice Sun Protection During Recovery

After the wound has healed, apply gentle sunscreen when going outdoors or cover the area with clothing. New skin is highly sensitive to ultraviolet (UV) rays. Exposure to sunlight can cause hyperpigmentation, darkening the healed area and leading to visible pigmented scars that affect skin appearance.

In addition, during the healing process, consuming foods rich in vitamin C and protein may support skin tissue repair. If abnormal tissue growth occurs, seek medical attention promptly for appropriate intervention.

How many moxibustion sessions at Yinbai (SP1) are needed to stop bleeding?
The use of moxibustion at the Yinbai (SP1) acupoint to stop bleeding should be determined according to the severity of bleeding. Mild bleeding usually improves after 3–5 sessions, while more obvious or recurrent bleeding may require 7–10 treatments; the exact number should be adjusted based on individual conditions. Accurate point location and proper temperature control are essential during moxibustion to prevent burns. It is also advisable to support treatment with a light diet. Adequate rest after moxibustion is important to promote recovery.

Soaking your feet in hot water every day: is it health preservation or slow suicide?
However, if conditions such as varicose veins in the lower limbs or diabetic foot are present, soaking feet in hot water may worsen local congestion or cause burns due to reduced sensation. Excessively high water temperature or prolonged soaking time may also lead to dizziness, palpitations, or damage to the skin barrier of the feet. These issues arise from improper practices or individual incompatibility, rather than indicating that foot soaking itself is harmful.

What are the hazards of inhaling refrigerant for humans?
Inhaling refrigerants can cause respiratory irritation, effects on the central nervous system, cardiovascular damage, frostbite and chemical burns, as well as oxygen deprivation leading to suffocation. The severity of these hazards varies slightly depending on the type of refrigerant, so accidental inhalation should be carefully avoided. If severe coughing, dizziness, palpitations, or difficulty breathing occur after inhalation, prompt medical attention is recommended.

At what temperature does airway humidification cause airway burns?
Airway humidification temperatures exceeding 41°C may cause airway burns; a range of 37–39°C is considered safe, as higher temperatures can easily damage the mucosa. When the humidification temperature is between 41°C and 45°C, mild airway mucosal burns may occur, manifesting as symptoms such as sore throat, dryness, and worsened cough. Although such temperatures do not cause severe tissue damage, they can disrupt the mucosal barrier and increase the risk of infection.

How long should a moxibustion session at the Yongquan point last?
Under normal circumstances, moxibustion at the Yongquan point (KI1) is recommended to last 10–15 minutes per session, which is suitable for routine health maintenance. In special cases, duration should be adjusted according to individual constitution. During moxibustion, it's important to maintain an appropriate distance to avoid skin burns and to choose a gentle moxibustion method. Regular and consistent sessions are essential; blindly extending the duration should be avoided in order to maximize the regulatory effects of acupoint stimulation.

How long does it take for hair to grow back after being burned off by fire?
When the scalp is injured, hair follicles may be temporarily or permanently damaged, and hair growth can significantly slow down. If burns cause redness and blistering of the scalp, the hair follicles enter a repair phase and may take over six months to potentially resume growth. In severe burns where hair follicles are extensively damaged, localized hair loss may occur. In such cases, medical evaluation is necessary to determine whether medical interventions are needed to assist follicle recovery.
