Climate Is Not a Detail in Wound Healing

Surgical wound healing is a physiological process that happens at the cellular level, but it does not happen in a vacuum. Skin temperature, moisture, bacterial load, and mechanical stress all influence whether a wound closes cleanly or stalls. South Florida, with average summer temperatures above 88 degrees Fahrenheit and relative humidity often exceeding 80%, presents a specific set of challenges that every patient should understand.

This article is written with summer in mind, but the principles apply year round.

Two Categories of Surgical Wounds

Every surgical wound falls into one of two categories, and the rules are different for each.

Closed incisions are the most common after a laparoscopic or robotic procedure, hernia repair, gallbladder removal, appendectomy, lump excision. The skin edges are approximated with sutures, staples, or surgical glue. Once the dermis seals, usually within 24 to 48 hours, the wound becomes a barrier against most external contamination.

Open or healing by secondary intention wounds include drained abscesses, debrided diabetic ulcers, and complex wounds managed with packing or negative pressure therapy. These wounds are deliberately left open and require active care until granulation tissue fills the defect.

The expectations, the risks, and the water rules are not the same.

The Real Rules About Water Exposure

The single most common question I hear in summer is some version of, "Can I swim?"

The general principles, supported by guidance from the American College of Surgeons:

• Showers are usually permitted 24 to 48 hours after a clean closed incision, with no scrubbing of the wound and gentle pat drying.
• Tub baths, pools, hot tubs, and ocean water should be avoided until the incision is fully closed and any sutures or staples are removed, typically 10 to 14 days, sometimes longer depending on the procedure.
• Open wounds should not be submerged at all until cleared by the surgical team, regardless of the water source.

The reason is not chlorine, it is contamination plus maceration. Prolonged moisture softens the skin barrier and gives bacteria, including Pseudomonas and atypical organisms in warm water, an entry point. South Florida pool decks, fresh water canals, and ocean inlets all carry their own microbial profiles.

Recognizing a Surgical Site Infection Early

Surgical site infection occurs in roughly 1 to 3% of clean elective abdominal procedures, with rates somewhat higher in contaminated cases. The classic signs:

• Redness that spreads beyond the incision rather than fading
• Increasing pain rather than gradually improving pain
• Warmth and swelling out of proportion to expected
• Drainage that is yellow, green, or foul smelling
• Fever above 101 degrees Fahrenheit

Early identification turns a minor problem into a manageable one. Late identification turns it into a return to the operating room.

The Wound Care Kit Every Patient Should Have at Home

Independent of season, a well stocked home kit reduces friction in recovery:

• Sterile gauze pads in multiple sizes
• Paper tape, which is gentler on skin than fabric tape
• Saline irrigation, single use bottles are convenient
• A clean pair of scissors, used only for dressings
• Antibacterial soap for hand hygiene
• A working thermometer
• A printed list of red flag symptoms and the surgical team's phone number

For diabetic patients or patients with poor circulation, add a small mirror for inspecting the back of the legs and feet, which we will revisit in our August article on diabetic foot care.

The Florida Summer Layer

On top of the evergreen rules, the summer specific considerations:

• Sweat management. Excess sweat under a dressing can macerate skin. Change dressings more often if needed and consider air conditioning generously.
• Sun exposure. New scar tissue is vulnerable to hyperpigmentation. Once the wound is fully healed, sunscreen with at least SPF 30 over the scar for 6 to 12 months reduces dark marks.
• Insect bites. Mosquito and ant bites near a fresh incision are not dangerous in themselves, but scratching can introduce bacteria. Topical antihistamines and avoiding scratching matter.
• Travel. Long flights or drives within the first 1 to 2 weeks can increase swelling and the risk of venous thromboembolism. Hydrate aggressively, walk every hour, and follow your surgeon's specific guidance.

The Bottom Line

Healing in Florida is not harder, it is just specific. A clean closed incision, treated with respect for the climate, heals beautifully. An open wound, supported by structured care and clear communication with your surgical team, also closes, but it earns it through discipline.
