What is aPain Thresholdand Why Does It Vary?
Why Pain is Actually the Ultimate Bodyguard
Physical pain is an unpleasant but vital sensory experience that signals potential or actual tissue damage. It acts as the body's built-in protective alert system. This can manifest as aching, burning, or tingling sensations, often localized in a specific part of the body. Whether you're pushing through a heavy set at the gym or accidentally touching a hot stove, your brain is constantly running diagnostics.
To understand what pain really is, it’s worth looking at its key aspects:
People with Congenital Insensitivity to Pain (CIP) or congenital analgesia do not experience physical pain due to rare genetic mutations. While that might sound like a superpower, it’s actually a dangerous condition that makes them incredibly vulnerable to injuries. Without that "pain signal," they can’t feel burns, fractures, or infections until it’s too late.
You’ve likely heard—or even used—the phrase “pain threshold.” When someone says theirs is high, they usually mean they have elite stamina or a "tough guy" vibe. But does science actually support the idea that some people just "feel" less pain than others?
"Pain is a protector, but it’s also a subjective opinion of the brain on what is happening in the body," says Dr. Beth Darnall, a Stanford University pain scientist, in an interview with Forbes.
What Exactly is a Pain Threshold?
Joshua Pate, a senior lecturer in physiotherapy at the University of Technology Sydney, and Tory Madden, a pain researcher at the University of Cape Town, explain that pain is an experience shaped by psychology and social context. It can depend on a massive variety of variables. In their research, they interviewed a group of kids and found that many associated pain with "toughness" or social clout. It seems social expectations shape our understanding of pain from a very young age.
There are many misconceptions about pain thresholds that can lead to inequality in healthcare. Scientists clarify that, technically, a pain threshold refers to the exact point at which a stimulus—like heat, cold, or pressure—actually starts to feel painful. However, this is not the same as pain tolerance, which is the maximum amount of pain a person can handle before they need relief or have to tap out.

These two concepts often get blurred in everyday conversation, but distinguishing between them is crucial, especially for medical professionals and researchers looking to provide customized recovery protocols.
Is Your Pain Threshold Fixed?
The stability of a pain threshold is a hot debate. Scientists are leaning toward the idea that it’s more of a “zone of uncertainty” rather than a fixed "on/off" switch. Pate and Madden suggest that in the future, tracking how much a person’s pain threshold fluctuates could provide valuable insights into their risk for chronic pain and help doctors pick the best therapy options—whether that's high-tech recovery gear like a Theragun or traditional physical therapy.
What Influences Your Pain Threshold?
A ton of factors go into the mix. Researchers suggest focusing on biological elements: genetics, hormones, and the nervous and immune systems.
Gender Differences
Men often report a higher pain threshold, which may be linked to hormonal differences and the influence of testosterone. On the flip side, gender differences in pain sensitivity often reflect social norms and the "Main Character" pressure for men to remain stoic and "walk it off."
Hair Color: The Redhead Factor
Some studies have shown that people with natural red hair may experience pain differently due to a variant of the MC1R gene. As noted in Vogue, this genetic quirk is a fascination in both the beauty and medical worlds. For instance, redheads might have a lower threshold for thermal pain (heat) but a higher threshold for electric shocks.
The Nervous System
For some people dealing with long-term or chronic pain, their threshold often drops. This is due to central sensitization, where the nervous system stays in a state of "high alert," overreacting to even minor stimuli as if they were major threats.
The Immune System
Your immune system can hijack your nerve signals. Inflammation from a common cold or the flu can suddenly make everything hurt. Many COVID-19 survivors experienced a short-term version of central sensitization, where even the smallest things triggered headaches or body aches. Acute injuries, like a sprained ankle, also cause inflammation that temporarily lowers the pain threshold in that area.
Non-Biological Factors
Biological stats aren't the whole story. Your mental state plays a massive role in how you handle discomfort.
Psychological Influence
Factors like anxiety, fear, and catastrophizing are directly linked to a lower pain threshold. If you're stressed about the pain, it’s going to hurt more. Conversely, strategies like mindfulness and relaxation—often practiced in Lululemon-sponsored yoga studios across the country—can significantly raise your threshold.
Social Influence
Cultural norms dictate how we perceive and express pain. Some cultures value stoicism and "keeping a stiff upper lip," while others view the open expression of discomfort as totally normal. This cultural "vibe check" can sometimes make it difficult for doctors to accurately diagnose how much pain a patient is truly in.
"We don't just feel pain in our bodies; we feel it in our minds. The context of the situation—whether you're on a sports field or in a hospital—changes the signal entirely," says pain specialist Dr. Elliot Krane.
