It is still spring and full of its long days, as well as the first hints of summertime heat. And what better way to take advantage of these rising temperatures than by splashing around in a cool dip into the pool? But keep in mind, while this kind of escape from heat is ideal in swimming, the same may not be said about your hair.

Chlorine, the same stuff that makes pools sanitary and bacteria-free, can be ruthless on your hair—removing natural oils, drying out your locks, and even turning lighter hair a dreaded greenish color. If you've ever emerged from the pool with your hair feeling brittle, knotted, or just. wrong, you're not crazy. The damage is real.

But first, before you stop using the pool completely, good news is there! Using some expert-endorsed preventative measures, you can continue with your swimming routines without concern over hair damage by chlorine. We asked Dr. Priyanka Sharma, who's an experienced dermatologist as well as hair transplant surgeon, to analyze how chlorine hurts your locks and divulge the ultimate fix for hair to be firm, healthy, and ready for summers.

How Chlorine Damages Hair?

Chlorine is a potent disinfectant meant to destroy bacteria and ensure water quality, but its severe chemical composition doesn't mix well with hair health. Based on scientific research, chlorine robs the hair of its natural oils, causing:

Drastic dryness and brittleness: Natural oils coat the hair shaft and keep the hair hydrated. Chlorine destroys these needed oils, making hair dry and more susceptible to breakage.

Frizz and split ends: Dehydration weakens the strands of hair, resulting in frizz and split ends.

Color fading and discoloration: Chlorine oxidizes the pigment melanin, which is responsible for the color of the hair. The oxidation can lead to a more rapid fading of natural or colored hair. Blondes can even turn green because chlorine interacts with trace amounts of metals such as copper present in the water.

Damaged hair structure: Chlorine degrades keratin, the protein giving hair strength and elasticity, increasing its vulnerability to damage and loss of thickness.

Signs of Chlorine-Damaged Hair

If you are a regular swimmer, it is worth being aware of the signs of chlorine damage from an early stage. Some of the most likely signs are:

• Hair that's rough or straw-like to touch
• More tangling and reluctance to comb the hair
• Reduced shine and luster
• Dryness which does not fade despite frequent conditioning
• Breakage and split ends occurring more often

Luckily, there are a number of preventative measures and after-swim care methods that can assist in shielding your hair from the destructive influence of chlorine.

Preventing and Dealing with Chlorine Damage

Pre-Swim Hair Protection Methods

1. Pre-Wet Your Hair

Before diving in, wet your hair with new, non-chlorinated water. Dermatologists say that pre-wetting hair diminishes its capacity for chlorine absorption because water-soaked strands are less permeable to chemicals.

2. Use a Protective Barrier

Pre-swimming applications of leave-in conditioners or natural oils such as coconut or argan oil can place a barrier in the way that restricts the penetration of chlorine. These moisture-rich products seal in moisture with a protective film, keeping your hair from drying out too much.

3. Use a Swim Cap

Although not always the height of fashion, a properly fitted swim cap will greatly minimize hair exposure to chlorinated water. Use silicone caps instead of latex ones, as they create a tighter seal and are less damaging to hair.

Post-Swim Hair Care Routine

4. Rinse Immediately After Swimming

The longer the chlorine remains on your hair, the more it damages it. Rinse with clean water as soon as you get out of the pool to wash away lingering chlorine before it can attach to hair proteins.

5. Apply a Chlorine-Removing Shampoo

Specialized shampoos that are designed to strip chlorine are a lifesaver for swimmers. These shampoos have chelating agents that attach to chlorine and other mineral buildup, lifting them out of the hair. Use shampoos with vitamin C or EDTA (ethylenediaminetetraacetic acid) to counteract chlorine exposure.

6. Deep Condition Regularly

To combat the drying effects of chlorine, include a deep conditioning treatment in your regimen at least weekly. Hair masks containing keratin, biotin, and shea butter replenish lost moisture and restore hair strength.

7. Restrict Heat Styling

Chlorine-damaged hair is already weakened, so exposing it to additional stress from heat styling can accelerate breakage. Minimize the use of curling irons, straighteners, and blow dryers, opting for air-drying when possible.

Expert-Approved Products for Chlorine-Damaged Hair

Dr. Sharma recommends the following products to protect and repair chlorine-exposed hair:

• Pre-Swim Leave-In Treatment: A silicone-based leave-in conditioner to coat the hair shaft.
• Chlorine-Removing Shampoo: A clarifying shampoo with vitamin C to eliminate chlorine buildup.
• Hydrating Hair Mask: A weekly deep conditioning treatment with keratin and natural oils to replenish moisture.
• Serum or Oil Treatment: Argan or coconut oil used after washing to seal in moisture and guard against future damage.

Chlorine damage is indeed a risk for regular swimmers, but by having the right prevention methods and hair care plan in place, you can spend your time in the pool without compromising the health of your hair. By pre-wetting your hair, employing protective products, and adopting a disciplined post-swim routine, you can reduce chlorine damage and have your hair appear healthy, robust, and lively.

So the next time you go swimming in the pool, take a few extra precautions to protect your hair—you'll be glad you did.

Last year in June, when a woman collapsed on an escalator at Buffalo's airport, and Phil Clough, who is an experienced emergency medical responder knew exactly what to do. He and a bystander, as the Washington Post reported, quickly laid the woman flat on her back. They checked her pulse and breath. Her pulse was faint and her breathing was shallow and erratic. A few moments later, she stopped breathing altogether.

Realizing she might be experiencing a cardiac arrest, Clough immediately began performing chest compressions. He pressed hard and fast on the center of her chest while other bystanders called 911 and fetched an automated external defibrillator (AED). Within seconds of receiving a shock from the AED, the woman opened her eyes. By the time the airport rescue team arrived, just minutes later, she was conscious and able to speak.

Clough’s quick actions saved the woman’s life, but he credits his preparedness to a life-changing incident several years earlier. After witnessing a woman collapse at his gym and feeling helpless, he took a college course to become certified as an emergency medical responder. This training allowed him to respond with confidence when faced with a life-or-death situation.

The Challenge of Cardiac Arrest

The woman in Buffalo was fortunate that bystanders knew how to respond. Unfortunately, most people who experience cardiac arrest do not receive immediate help.

According to the American Heart Association, more than 350,000 cardiac arrests occur outside of hospitals in the U.S. annually. Tragically, 90% of these individuals do not survive, often because help arrives too late. For each minute that passes without intervention, a person’s chances of survival decrease by 10%. However, with prompt cardiopulmonary resuscitation (CPR) and an AED shock if necessary, survival rates can double or even triple.

Despite the importance of swift intervention, fewer than half of people who suffer cardiac arrest outside of a hospital setting receive immediate assistance. This lack of action is often due to a lack of training and preparedness. Cardiac arrest can happen anywhere, but with public access to AEDs and trained bystanders, survival rates could improve dramatically.

The Role of AEDs in Saving Lives

A crucial part of treating cardiac arrest is the use of an AED, a portable device that delivers an electric shock to the heart. The AED analyzes the heart’s rhythm and guides the user through the steps to apply a shock if needed. Although many states require AEDs to be available in public places such as airports and malls, they are not always easy to find. A study spanning 2019 to 2022 revealed that in public settings, AEDs were used only 7% of the time, and CPR was performed 42% of the time after a cardiac arrest incident.

To address this issue, PulsePoint, a nonprofit organization, has registered 185,000 AEDs in 5,400 U.S. communities, reports the Washington Post. The group’s goal is to help communities build their AED registries and integrate them with local 911 services. In addition, PulsePoint’s mobile app alerts trained CPR responders about nearby cardiac arrests and identifies the closest AEDs, enhancing the chances of saving a life.

Overcoming Barriers to Bystander Intervention

While CPR and AED knowledge can save lives, many people hesitate to intervene during an emergency due to fear of making a mistake, lacking confidence, or worrying about legal liability. However, all 50 states and Washington, D.C. have “Good Samaritan” laws that protect individuals from legal consequences when they provide help in a medical emergency.

Lack of CPR training is another significant barrier. A study found that only 18% of people had received CPR training within the last two years, which is crucial for skill retention. Although many people have received CPR training at some point in their lives, the skills may be outdated or forgotten.

To address this, some states have made CPR training mandatory for high school graduation, and countries like Denmark and Norway have implemented similar requirements. In the U.S., CPR courses are widely available online and in-person, and many take just a few hours to complete. These courses teach individuals the basics of CPR, which involves performing chest compressions at a rate of 100 to 120 per minute and a depth of at least two inches.

You may have heard people say that they are allergic to things, whether it is gluten, soy or peanuts. These people avoid these items, even going as far as not dining in certain places where there is a possibility of cross contamination.

While it may seem like an overreaction, allergy symptoms can range from just a few rashes to cause of death. There are many people who did not and still do not take allergies seriously. As one of the most common allergies, many people who have close ones with peanut allergy, many places have opened “nut-free” zones including schools, offices and many public spaces.

While there is no cure for allergies, a new clinical trial results show that exposure therapy with peanut allergies has proven successful.

Why Do We Need Exposure Therapy?

The research team reported in the journal Allergy, April 2025, that a significant majority of the participants, more than two out of every three (67%), were able to eat at least five peanuts without triggering an allergic reaction after undergoing the treatment. This marks a positive step forward in managing this common and often severe allergy.

Seeing as expansive as the risk associated with allergies is, researchers have continued working towards proper cures and treatments. While there are precautions like avoiding the allergens, reducing exposure, when a person with a sever, allergy is exposed to the allergens, the chances of them going into anaphylaxis is a lot, so many people care EpiPens or epinephrine shot that can counter allergic reactions for a while.

How Does Exposure Therapy Work For Peanut Allergies?

The way exposure therapy works is pretty simple but needs to be done carefully. People who are allergic to peanuts are given very, very small amounts of peanut protein every day. Over time, the amount is slowly increased. It's like gently introducing the body to the thing it's allergic to, little by little. This helps the body learn that peanuts aren't actually a threat, and it starts to react less strongly. It's a gradual process, but the goal is to build up a person's ability to handle peanuts without having a dangerous allergic reaction.

In this study, 21 adults who were allergic to peanuts took part. Every day, they ate a small amount of peanut flour mixed in with their food. The goal was for them to be able to eat a small amount of peanut flour every day for at least a month without any problems. After that, they were tested to see how much peanut they could eat. The researchers were very happy with how well the treatment worked, saying that the results were similar to what they've seen in studies with kids.

The study showed some really impressive results in how much more peanut the participants could handle after the treatment. The researchers mentioned that on average, the amount of peanut they could eat without a reaction went up by a hundred times!

Why Are Researches Like This Important?

What makes this study really important is that it's the first-time scientists have specifically looked at how well exposure therapy works for adults with peanut allergies. Usually, this kind of treatment is done with kids because their bodies are still growing and changing. However, this new research shows that even adults, whose bodies are already fully grown, can still become less allergic to peanuts with this type of treatment. This opens up a whole new possibility for adults who have lived with this allergy for many years and haven't had many treatment options before. Many said that the treatment was "life-changing" and they no longer lived in constant fear of their allergy.

Every three seconds someone in the world develop dementia. Forgetting things every now and then is normal, it happens to everyone. However, nobody expects to lose their sense of being, all the memories and life experiences that make you who you are. Dementia is the condition that makes all of these fears come true. It is a collective name for different brain syndromes which affect one's memory, thinking, behavior as well as emotions.

Many symptoms of dementia are vague, especially early ones, and they can easily mislead people. However, a new technological advancement may help people get diagnosed early, through shoes.

How Can Shoes Help Us Diagnose Dementia?

This new technology, published in Science Advances in April 2025, works by using special insoles you put inside your shoes. These insoles have tiny sensors that can feel the pressure when you walk or stand. What's really clever is that these sensors don't just feel pressure; they turn that pressure into tiny electrical signals. These signals carry hidden information about how you move and how your body is working, kind of like secret messages from your feet that can tell a story about your health without you even realizing.

How Do These Shoes Work?

The electrical signals created by the smart insoles are then sent wirelessly to a special application on your smartphone, just like getting a text message. This app takes all that data and turns it into easy-to-understand pictures and information about how you walk and stand. It can show exactly where you put the most pressure on your feet and how your movement changes over time. Even more impressively, the app uses smart computer programs to learn and recognize different ways you move, like sitting, standing, or running, giving a detailed look at your daily activities.

For patients who might be developing health issues, the smart insoles could provide early clues that doctors can use to make diagnoses sooner. For athletes, this technology can help them understand their posture better, which can prevent injuries and improve their performance. If someone is recovering from an injury, the insoles can track their progress and make sure they are healing correctly.

Researchers have already discovered that the way people walk can change when they have certain health problems, especially conditions that affect the brain and nerves, like Parkinson's disease. People with Parkinson's might start to shuffle their feet or lean to one side when they walk. The team behind these smart insoles believes that by having much better sensors in shoes, doctors could get a more accurate and earlier warning sign of these kinds of conditions just by analyzing someone's walk. This could lead to earlier treatments and better management of these challenging illnesses.

Why Is Early Diagnosis Important?

According to Alzheimer’s Disease International there are 55 million people living with dementia in 2020.

Their research shows that most of the people who have dementia have not received proper treatment for the same. About three quatre of the people who have been diagnosed with dementia lack treatment or have access to healthcare. Even in high-income countries only about 20-50% of people receive the proper care they need.

This treatment gap can only be fixed when people start getting a diagnosis. Not just receiving care, but receiving early diagnosis and treatment is crucial for proper dementia care, as explained by World Alzheimer Report 2011.
