- Type of Riding: Aggressive riding styles or riding in hazardous conditions may subject your helmet to more impacts.
2.1 How Does Sunlight Affect a Bike Helmet?
Sunlight, specifically ultraviolet (UV) radiation, is a significant factor in the degradation of bike helmets. UV exposure can weaken the helmet’s outer shell and the EPS foam that provides crucial impact absorption.
- Shell Degradation: The outer shell, often made of polycarbonate, can become brittle and lose its structural integrity when exposed to UV rays.
- Foam Degradation: UV radiation can cause the EPS foam to harden and lose its ability to compress and absorb impact energy effectively.
2.2 How Do Extreme Temperatures Affect a Bike Helmet?
Extreme temperatures, whether hot or cold, can negatively impact the materials used in bike helmets. High temperatures can cause the EPS foam to soften and lose its structural integrity, while extremely cold temperatures can make the shell brittle.
- High Temperatures: Leaving your helmet in a hot car can expose it to temperatures exceeding 120°F (49°C), which can deform the foam and compromise its protective capabilities.
- Low Temperatures: While less common, exposure to freezing temperatures can make the helmet shell more prone to cracking upon impact.
2.3 How Does General Wear and Tear Affect a Bike Helmet?
General wear and tear, including minor impacts, scratches, and handling, can accumulate over time and reduce the effectiveness of your bike helmet.
- Minor Impacts: Even small bumps and knocks can create micro-fractures in the EPS foam, weakening its ability to absorb future impacts.
- Scratches and Abrasions: Scratches on the outer shell can compromise its structural integrity and make it more susceptible to cracking.
3. When Should You Replace Your Bike Helmet After an Impact?
You should replace your bike helmet immediately after any impact, even if there is no visible damage. The EPS foam is designed to compress and absorb impact energy, and once it has done so, it may not provide the same level of protection in a subsequent impact.
Barry Miller, PhD, director of outreach and business development for the Virginia Tech Helmet Lab, emphasizes that a used helmet may not perform to the same level as a new helmet due to the degradation of impact material.
3.1 What Kind of Impact Requires Immediate Helmet Replacement?
Any impact that involves your head striking a surface warrants immediate helmet replacement. This includes:
- Crashes: Any bicycle crash where your head makes contact with the ground or another object.

3.2 How Do You Inspect a Helmet for Damage After an Impact?
Even if your helmet appears undamaged after an impact, it’s crucial to inspect it thoroughly for hidden damage.
- Check the Shell: Look for cracks, dents, or any signs of deformation.
- Inspect the Foam: Press firmly on the EPS foam to check for soft spots or areas that compress easily.
- Examine the Straps and Buckles: Ensure the straps are not frayed or damaged, and the buckles function properly.
3.3 What if There is No Visible Damage After an Impact?
Even if you cannot see any visible damage, the helmet’s internal structure may have been compromised. The EPS foam is designed to absorb impact by compressing, and this compression may not always be visible. It’s always best to err on the side of caution and replace the helmet after any impact, regardless of its apparent condition.
