Lice are tiny insects that live on human scalps, feeding on blood. They’re common among children, especially those who spend time in close contact. Lice don’t spread disease, but they do cause itchiness and irritation. For swimmers, a big question often arises: does swimming in a chlorinated pool kill lice? This article will dive into everything swimmers need to know about lice, chlorine, and effective ways to prevent and treat lice.
Introduction to Lice
Lice are tiny, wingless insects that crawl from head to head through direct contact or by sharing personal items like combs, hats, or towels. They cannot jump or fly, but they’re skilled at gripping onto hair strands, making them hard to dislodge. Lice can survive on a host for about 30 days, but without a host, they perish within 24 hours. [CDC]
Does Chlorine Kill Lice?
Chlorine is widely used in swimming pools to kill bacteria and prevent infections. However, it does not have the same effect on lice. Studies show that lice can survive in chlorinated water. One study found that lice temporarily become inactive in chlorine but recover quickly once out of the water. Even after 20 minutes submerged, lice survived and resumed movement once back in the air.

Why Doesn’t Chlorine Kill Lice?
Lice have strong claws that allow them to cling tightly to hair, even underwater. Chlorine, at the concentration found in swimming pools, is not toxic enough to kill them. According to the National Pediculosis Association , lice have a waxy outer coating that makes them resistant to many environmental threats, including chlorinated water.
Expert Insight
According to the Centers for Disease Control and Prevention (CDC), chlorine in pool water does not kill lice. Medical professionals confirm that lice are equipped to withstand the typical levels of chlorine in swimming pools, meaning a dip in the pool won’t get rid of them.
Can Lice Spread in Swimming Pools?
Lice don’t spread through water. While they can survive underwater, they cling to the hair and are unlikely to let go. A study that had infected individuals swim with non-infected individuals found no evidence of lice spreading from person to person in the pool. However, sharing personal items associated with swimming, like towels or swim caps, can lead to lice transmission. [Journal of Medical Entomology]
How Can Lice Be Spread Among Swimmers?
- Sharing Towels: Towels that touch the hair can carry lice from one person to another.
- Swim Caps and Goggles: These items, if shared, may carry lice between swimmers.
- Changing Rooms: Lice can transfer through personal items left in common spaces, like changing room benches or shelves.
Risks of Using Chlorine to Treat Lice
Some people may think stronger chlorine solutions could kill lice. However, using concentrated chlorine or pool chemicals on the scalp is unsafe. High concentrations of chlorine can cause:
- Skin burns and blisters
- Eye damage or irritation
- Respiratory issues, nausea, and throat irritation
Why Chlorine Isn’t an Effective Treatment for Lice
Chlorine doesn’t penetrate the lice’s protective coating. The CDC and the American Academy of Pediatrics recommend avoiding chlorine for lice treatment because it isn’t effective and poses health risks.
Effective Lice Treatments
- Over-the-Counter Treatments: Most people use lice shampoos or lotions, like pyrethrins or permethrin lotion, which kill lice on contact.
- Prescription Medications: In tougher cases, prescription treatments such as ivermectin lotion or benzyl alcohol lotion are used.
- Combing: A fine-toothed lice comb removes lice and their eggs. Using a lice comb alongside a treatment increases effectiveness.
- Home Remedies (Caution): Although methods like olive oil or mayonnaise are popular, they’re not proven to work.
Can You Go Swimming After Lice Treatment?
After a lice treatment, it’s generally advised to wait before swimming, especially in chlorinated pools. Chlorine can interfere with lice treatments because some treatments, such as those containing permethrin, may lose effectiveness when exposed to chlorine, making it essential to let the treatment work without interference. Always refer to the specific treatment instructions and consult with a healthcare provider if unsure
According to NC State Extension Publications, It’s best to avoid swimming or washing hair for 24-48 hours after using a lice treatment to ensure the treatment works effectively.
How to Prevent Lice for Swimmers
Swimmers can reduce the risk of lice without compromising their swimming routines by following these tips.
1. Avoid Sharing Personal Items:
One of the easiest ways for lice to spread is through shared items that come in contact with hair. Female swimmers, especially those with longer hair, should avoid sharing towels, swim caps, brushes, or hair ties with others. It’s also best to have personal items like swim caps labeled to avoid accidental sharing.
2. Tie Up or Braid Long Hair:
Long hair provides more surface area for lice to cling to. Female swimmers can reduce the risk by tying their hair back tightly, wearing it in a bun, or braiding it before swimming. Wearing a snug-fitting swim cap over tied or braided hair adds another layer of protection against lice.
3. Use a Lice-Repellent Spray or Essential Oils:
Some lice-prevention sprays contain essential oils like tea tree, lavender, or peppermint, which may deter lice. Lightly spraying hair or using hair products with these oils before swimming can help protect against lice. However, always check if the pool allows such products, as oils can sometimes interfere with pool maintenance.
4. Keep Personal Items Separate:
In crowded locker rooms, keeping personal items in a closed bag or locker can prevent lice from transferring through shared surfaces. To limit exposure, ensure that items like brushes and caps are stored securely in separate compartments of a swim bag.
5. Routine Lice Checks:
Regular lice checks, especially for female swimmers who frequently use shared facilities, can catch infestations early. Parents and individuals can perform checks at home by carefully combing through damp hair with a fine-toothed lice comb, paying close attention to the roots and scalp.
6. Educate on Hygiene and Personal Space:
Swimmers should be mindful of head-to-head contact, even in social settings at the pool or locker room. Avoiding close contact and not touching other people’s hair can minimize the risk of lice. Parents and coaches can remind young swimmers about maintaining personal space and the importance of hygiene to help keep everyone lice-free.
7. Choose the Right Swim Cap Material:
Certain materials, like silicone or latex swim caps, fit tightly and can better prevent lice from coming into contact with hair. Female swimmers with long hair should consider these materials, as they tend to be more durable and form a tighter seal around the hair.
What Swimmers Need to Know
While lice can survive in pool water, the good news is they rarely spread in the water itself. Lice hold tightly to hair underwater, making transmission unlikely in the pool. However, swimmers can still catch lice by sharing personal items or being in close contact outside the pool. Swimming pools are not a reliable way to get rid of lice, and chlorine is not an effective lice treatment.
Conclusion
While chlorine is great for keeping pools clean, it doesn’t help with head lice. If someone in your family has lice, avoid relying on a pool to eliminate them. Use proper treatments and avoid sharing personal items. For swimmers, keeping these simple tips in mind can help prevent the spread of lice and keep everyone itch-free.
