Wound Healing: 7 Hidden Factors & Why Red Therapy Helps

Wound healing is a complex biological process involving a series of coordinated events aimed at restoring injured tissues. This intricate process is influenced by a multitude of factors that can either promote or hinder healing. The rising occurrence of chronic wounds, particularly among the aging population, presents a significant challenge to healthcare systems, contributing to increased expenditures and highlighting the need for effective wound care strategies, as detailed in this Frontiers in Immunology review. This article delves into the key factors contributing to wound healing, drawing upon insights from peer-reviewed medical papers and reputable medical websites.

Local Factors Influencing Wound Healing

Oxygenation: While oxygen is vital for cell metabolism and energy production in wound healing, the wound environment is initially often hypoxic due to disrupted blood vessels and high oxygen demand from active cells. Information on organizations involved in wound care can be found at the Alliance of Wound Care Stakeholders website. Restoring and maintaining adequate oxygen supply to the wound area is crucial, as persistent hypoxia can significantly impair healing.

Infection: The presence of foreign bodies and microorganisms in the wound bed can lead to localized infections that disrupt the healing process. Research published on the factors affecting wound healing elaborates on this. When the skin barrier is compromised, harmful microorganisms can enter, potentially causing tissue necrosis, complications like amputation, and even sepsis. The Wound Pros website highlights the most important factors in this process.

Bioburden: The level of microbial burden in a wound, including planktonic bacteria and biofilm colonies, plays a critical role in healing. As Medline Newsroom explains regarding environmental factors, an acute wound can transition into a chronic wound due to high bioburden, and existing chronic wounds may struggle to heal. Further details on factors influencing wound healing are available from Physiopedia. The following table outlines the five stages of microbial burden in wounds:

Stage Description Host Reactions
1 (least microbial burden) Contamination: Microorganisms are present but not proliferating. No significant host reaction or delay in healing. Host defenses destroy microorganisms via phagocytosis.
2 Colonisation: Microorganisms are present and undergoing limited proliferation. No significant host reaction or delay in wound healing. Due to the skin microbiome, all open wounds are colonized with microorganisms. These may also arise from exogenous sources or environmental exposure.
3 Local infection: Microorganisms proliferate, evoking a host reaction that can delay wound healing. Infection is contained within the wound and periwound region (<2cm). Local infection may present with covert signs and symptoms initially. As infection progresses, overt signs and symptoms become evident.
4 Spreading infection (cellulitis): Extending induration, spreading erythema (>2cm from wound edge), inflammation, crepitus, wound breakdown/dehiscence, lymphangitis. Spreading infection may involve deep tissue, muscle, fascia, organs, or body cavities, resulting in more widespread signs and symptoms.
5 (greatest microbial burden) Systemic infection: Malaise, lethargy, loss of appetite, fever/pyrexia, severe sepsis, septic shock, organ failure, death. Invading microorganisms spread throughout the body, evoking a massive host response. Systemic inflammatory response can also be triggered by local infection.

Temperature and Moisture: Maintaining an appropriate temperature and a moist, but not overly wet, environment within the wound bed is crucial for promoting healing. Environmental influences on wound healing are discussed by Medline. Excessive moisture can lead to maceration, while dryness can impede cell migration and tissue regeneration.

Blood Flow and Nutrient Availability: Adequate blood flow delivers oxygen, nutrients, and immune cells to the wound site. Logansport Memorial Hospital highlights how conditions like peripheral artery disease, which compromise blood flow, can significantly delay healing.

pH: Maintaining a balanced pH within the wound environment is crucial for optimal healing. An acidic pH can promote inflammation and impede cell growth, while an alkaline pH can hinder enzyme activity and impair tissue repair.

Systemic Factors Affecting Wound Healing

Age and Sex: Older adults (60 years and older) are more susceptible to delayed wound healing due to age-related physiological changes, including decreased collagen synthesis, impaired immune function, and reduced blood flow. As explained by The Wound Pros, sex hormones also influence wound healing, with estrogen promoting and testosterone potentially delaying the process.

Stress: Stress significantly impacts wound healing. Elevated cortisol levels, impaired immune function, and disrupted sleep patterns associated with stress can hinder the healing process. Further information on factors affecting wound healing can be found on Physiopedia. Furthermore, stress often leads to unhealthy behaviors like smoking and alcohol consumption, which further impede healing. It is crucial to address stress and its associated factors holistically to improve wound healing outcomes.

Diabetes: Hyperglycemia impairs various aspects of wound healing, including immune response, collagen synthesis, and angiogenesis. Physiopedia’s resource on factors affecting wound healing emphasizes that maintaining optimal blood glucose control is crucial for promoting wound healing in individuals with diabetes.

Obesity: Obesity is associated with impaired wound healing due to factors like decreased tissue perfusion, increased tissue tension, and altered immune responses. The literature on factors delaying wound healing notes that adipocytes release factors that interfere with normal inflammatory and immune processes, further hindering healing.

Medications: Certain medications, such as steroids, NSAIDs, and chemotherapy agents, can impair wound healing by suppressing the immune system, reducing inflammation, or interfering with cell growth. A resource outlining factors delaying wound healing provides more information on this.

Lifestyle Factors: Smoking and alcohol consumption can significantly delay wound healing. According to research published in PMC, smoking reduces oxygen delivery to tissues, impairs immune function, and increases the risk of infection. This same PMC article also details how alcohol interferes with collagen synthesis, impairs immune response, and can lead to nutritional deficiencies.

Nutrition: Adequate nutrition is essential for providing the building blocks necessary for tissue repair and regeneration. Deficiencies in protein, vitamins (especially vitamin C), and minerals (such as zinc) can impair collagen synthesis, immune function, and overall wound healing. More on these factors delaying wound healing can be found here.

Nervous System: Both the sympathetic and parasympathetic divisions of the autonomic nervous system play important roles in the wound healing phases, as detailed by Physiopedia.

Types of Wounds and Healing Processes

Wounds can be classified as open or closed. Closed wounds, like bruises, involve damage to underlying tissues without breaking the skin surface. Open wounds, on the other hand, involve a break in the skin and can be further categorized into:

Wound Type Cause Depth Healing Process
Abrasions Rubbing or scraping against a hard surface Superficial Typically heals quickly with minimal scarring
Lacerations Cuts from sharp objects Deeper than abrasions May require stitches and can result in scarring
Punctures Small, deep wounds caused by pointed objects Can penetrate deep into tissues May require cleaning and monitoring for infection
Avulsions Partial or complete tearing away of skin and underlying tissue Varies depending on severity May require surgical intervention and can result in significant scarring
Surgical wounds Incisions made during surgical procedures Varies depending on the procedure Typically closed with sutures, staples, or surgical glue
Traumatic wounds Cuts, lacerations, or puncture wounds that damage both skin and underlying tissues Varies depending on severity May involve significant tissue damage and require specialized care

Surgical wounds are closed in one of three ways: primary intention (closed immediately), secondary intention (left open to heal by granulation), or tertiary intention (initially left open and later closed surgically). The American Red Cross provides information on different types of wounds. Acute traumatic wounds often have visible tissue layers along the inside of the cut, as explained by UT Health Jacksonville.

The healing process typically involves four overlapping phases:

Factors Delaying Wound Healing

Several factors can disrupt the normal wound healing process and lead to delayed healing or chronic wound formation. The WCEI Blog provides a list of over 20 factors that can impact healing.

Light Therapy and Wound Healing

Red and near-infrared light therapy can accelerate wound closure and reduce scarring. Degree Wellness discusses how this therapy works by increasing circulation and promoting the formation of new capillaries, which enhances the delivery of oxygen and nutrients to the wounded area. Red and infrared light achieve this by:

Blue light therapy can also address skin problems through its photodynamic and anti-inflammatory actions, promoting healing. Wounds International explores this therapy’s role in reactivating healing. Blue light interacts with specific molecules in the skin, triggering photobiological reactions that result in anti-inflammatory effects while promoting the repair and healing of damaged skin tissue, as detailed in a MAG Online Library article. Combining blue light (460 nm) with red light (660 nm) can be particularly effective in treating ulcers, according to research published in PMC. The blue light reduces the risk of infection, while the red light promotes tissue repair and healing. This combination can speed up the ulcer healing process.
