When talking about faster wound healing, we need to separate fact from fiction. The truth is, even though people might associate salt water with healing, moisture can quickly cause the skin to swell around wounds and complicate the healing process. This not only affects the healing process, but can also allow bacteria to enter the wound, thereby increasing the risk of infection. Each type of water has its own particular kind of risk. Reading Better protection for better healing will tell you how to protect your wounds from water. But first, here are the types of water most people are most frequently exposed to and the dangers they present for wounds.
The healing powers of saltwater are primarily a myth.


Most people have probably heard that seawater helps the wound healing process – but this is a myth! In reality, impurities in the water in coastal areas and in standing bodies of water can contain high concentrations of germs that proliferate freely at warm temperatures.


It’s also important to protect wounds against tap water.

Tap water

Especially when a wound is just beginning to heal, it is advisable to protect the wound from direct contact with tap water. Water and moisture cause the skin to swell and this can impair wound healing. Hand soap, shampoo, shower gel and detergent can also irritate the wound. Before showering, bathing or washing your hands, it is important to make sure your wounds are covered with a waterproof plaster so that they are protected and can heal properly.

Wounds need also to be protected against chlorinated water, it can also slow the healing process, and bacteria in public pools can infect wounds.

Chlorinated water

Chlorine in water can cause unnecessary irritation in wounds and slow healing. There are also many invisible dangers at public swimming pools, such as the bacteria that loom in unsanitary pools that can quick lead to wounds becoming infected. It is important to take special care to securely protect wounds from chlorinated water, especially at popular swimming pools.

To ensure optimal protection against water, consider the 100% waterproof plasters from Hansaplast Aqua Protect. For protecting larger areas, consider Aqua Protect XXL that includes patented silver technology, thereby reducing the risk of infection.


Whenever your skin comes into contact with water – even when washing – consider waterproofing your wounds.

Waterproofing is the answer

Whether you find yourself at the beach, dealing with a pile of dirty dishes or heading out for your weekly swim, it is important to protect your wounds from water at all times. It is important to use plasters that stay securely in place – even during prolonged contact with water – and they should be breathable and flexible to allow you to move around freely. Hansaplast Aqua Protect plasters ensure that wounds stay well-protected and heal safely. They are also ideal for use after minor surgical procedures such as the removal of a mole.

”Water and moisture cause the skin to swell. This not only affects wound closure and the healing process, but can facilitate the entry of bacteria and increase the risk of a wound becoming infected. It is therefore important to protect the wound reliably from germs and water.“

The best protection is prevention

Exposure to dirt and bacteria can increase the risk of infection – which is the greatest threat to a healthy healing process. Public swimming pools can often contain the types of dirt and bacteria that are harmful to wounds. That’s why it’s so important to respect proper hygiene before, during and after your visit to the pool while enjoying the swimming season.

Here are some tips:

Never forget to shower
When people get into the pool without showering first, they carry lots of dirt and bacteria into the water. A quick shower before jumping in washes away up to 90 % of sweat, dead skin and skincare products.

Avoid footbaths at public swimming pools
You will find footbaths quite often at swimming pools, but few people realise they can do more harm than good. Since they are used so frequently, a high concentration of bacteria and germs can build up. Most people do not usually leave the disinfection long enough to act – it should be allowed to dry for at least 15 minutes to be effective.

Dry your feet thoroughly and wear flip flops
The best protection against infection at public swimming pools is actually quite simple – wear flip flops! It is also important to dry your feet carefully, especially between the toes. Since this area is often neglected, it is particularly susceptible to fungal infections. The warm moist environment between the toes provides the ideal environment for bacteria and fungi to grow.
