For Maria*, 37, the feeling starts whenever she’s too close to strangers. “I was at a really busy networking event recently and the air felt so thick and stuffy, I could barely hear anyone,” she recalls. “After a while, I couldn’t really breathe because of how close they were to me.” After a few minutes, the panic had become too much. So she left. “I was too focused on germs that might be circulating.” Maria avoids hugging and shaking hands, has stopped drinking and eating meat, and refuses to be around smokers. She also tries not to meet people indoors. Maria is one of many people suffering from health anxiety, an affliction formally known as hypochondria, which describes those who have a persistent fear of being or becoming unwell. According to the NHS, symptoms can include constantly worrying about your health, frequently checking your body for signs of illness, and obsessively looking at health information on the internet. It can be debilitating and, in instances of intrusive thoughts, can be related to obsessive-compulsive disorder (OCD).

It’s something I’ve experienced a lot myself. What started as minor fixations on ailments, like coughs and bruises, has metastasised as I’ve got older into something that can consume my daily life. A single headache can become the source of a health scare that dominates several hours of the day, while a new mole can send me diving deep into an internet rabbit hole about the causes of and treatments for skin cancer. Likewise, hearing or reading about a young person suddenly dying from some sort of unexpected and rare illness will have me convincing myself I’m next.

There are limited studies into the prevalence of health anxiety, given how difficult it is to determine and diagnose – none of which is helped by the fact that hypochondriacs have a history of being dismissed, laughed at, and belittled. It was only formally recognised as a condition by the American Psychiatric Association in 2013, which termed it “illness anxiety disorder”. Nonetheless, it’s something to be taken seriously, particularly in light of one recent Swedish study which found that people with illness anxiety disorder may die sooner than others.

With the inundation of health information accessible online, and the countless viral TikToks about the “warning signs” for any and every condition out there, it’s no wonder that experts believe health anxiety is on the rise. And it’s particularly prevalent among young people, who are more active on the internet. There also seems to be an influx of reports on the worsening health of younger people. Cancer diagnoses for those under the age of 50, for instance, have risen by 24 per cent in two decades — and stats such as these obviously exacerbate underlying fears.

“The internet and social media have made vast amounts of medical information (and misinformation) easily accessible,” says Dr Louise Goddard-Crawley, a psychologist specialising in health anxiety. “While this can empower people to take charge of their health, it also exposes them to worst-case scenarios, leading to heightened fears about minor symptoms.” This was the case for Emma Last, 49, founder of Progressive Minds, which specialises in workplace wellbeing. “I found a lump in my breast, which turned out to be a cyst, but waiting for that result was the longest few weeks of my life,” she recalls. “I was continually ruminating about all of the ‘what-ifs’ and had written letters in my head to my children in case the worst happened. I’d even planned my funeral during one car journey.” Perhaps it doesn’t help that there has been an increased awareness of wellness in recent years. What might’ve started as an interest in healthy eating can easily evolve into something more obsessive, fuelled by the rise of clean eating influencers peddling the benefits of chia seeds and superfood powders.

“With constant reminders to eat healthily, exercise, and avoid stress, people may become overly vigilant about their health,” adds Dr Goddard-Crawley. “This hyper-awareness can lead to a preoccupation with potential illnesses, even when the risk is low.”

A boom in wellness tech, too, has been a burden – products designed to help people monitor good health can easily become a gateway to serious health anxiety. “Health-tracking technologies, such as wearable devices and apps, can be beneficial for promoting wellness but can also encourage an obsessive focus on bodily functions, like heart rate or sleep patterns, turning normal fluctuations into sources of anxiety,” says Dr Goddard-Crawley.
