Fears grow over Canadian psychologist Jordan Peterson's health after his daughter's cryptic Father's Day post and his sad health update left fans disheartened. 

Peterson, 64, became popular with young men as a best-selling author, public speaker and clinical psychologist. He is predominantly known for his work in the 'manosphere' and controversial views on gender, politics and society. 

Yet, the author who boasts a cozy net worth of over $100 million began to battle serious illness late last year and was admitted to intensive care. 

He continued to tackle his health woes through a number of eyebrow-raising techniques, including a heavily-frowned upon red meat-only diet and a 'rapid detox' medically induced coma. 

According to his daughter, Peterson has been suffering from a condition called akathisia, which causes intense restlessness, an inability to keep still and a constant feeling of terror. 

Others suffering from the same debilitating condition described it was the most 'frightening hell a human can experience,' and has even led some down the path of suicide.  

But nearly a year later, Peterson's health appears to have made little improvement as a cryptic message from his daughter, 34-year-old Mikhaila, on Father's Day offered little hope. 

A photo of the pair from years ago was shared on X by Peterson's daughter, accompanied by the words: 'Happy Father's Day. Miss you.' 

The message left fans and Mikhaila's followers confused, with many questioning if the author was still alive. 

One user commented: 'Miss you? Is he still alive?'

'Is he dead,' another wrote. 

'Wait where is he?' a third comment read.

The post also received backlash, including one user who said: 'This is the most blatant engagement post, that’s so sad that you are using your dad for that smh.'

'Miss you? Kinda weird to write when he's been battling for his life... Would be disgusting to use your father's illness for engagement,' another wrote.

However, plenty of users showed their support for Peterson and his daughter, wishing the author a speedy recovery. 

'Love this picture. Thank you for sharing. I hope your Dad returns to full health soon. The world needs him,' one said.

A second read: 'Get well soon, Jordan, we need you!'

'We miss you Jordan. Get well soon,' another user shared.

'Happy Father's Day to a man who has been a father figure for many. Wishing you all the best, Sir. Mikhaila, keeping you and the family in our prayers,' a fourth wrote. 

The Father's Day message was soon followed by Peterson's own announcement on Instagram that gave little hope for the influencer's recovery. 

'Hi everybody. I'm pleased to let you know that we're going to release a lecture a week form my extensive tour archive, beginning this Sunday and then repeating every Sunday after that,' Peterson wrote on Sunday. 

'This allows me to do something interesting and useful while I'm otherwise incapacitated. My health is such at the moment that I can't really return to podcasting or public lecturing.'

Peterson went on to say that the recordings were created 'with the express intention of preparing them for release, and we've determined that this is a very good time to do that.'

'So that’s what’s going to happen.'

He went on to add his hopes that the recordings would be 'useful and compelling,' particularly for fans of his early work on YouTube 'that was very lecture focused.' 

'It’s a return to my roots, I suppose, in some ways. And I’m as happy as I can be under the current circumstances, given my ill health, to be participating in this process and to have these lectures prepared for release. Thanks a lot for your continued attention and support,' he concluded. 

Peterson recently celebrated his 64th birthday on June 12, as his daughter posted a photo of the pair from the year before and wished her father a happy birthday. 

The celebratory post, however, also came with a sad sentiment as she revealed that both she and her mother skipped their birthdays.

'This isn't the year for parties unfortunately but maybe next year,' she wrote on Instagram. 

Mikhaila, who appears to be managing her father's affairs in his absence, said she believed his condition was triggered by anti-anxiety medication that he was prescribed following his wife's cancer diagnosis in 2020. 

His daughter – who has been criticized for embracing unproven medical theories – additionally claimed that her father was diagnosed with an autoimmune condition triggered by exposure to toxic mold. 

Known as CIRS, it is hard to diagnose and not widely accepted in mainstream medicine. 

She says too that complications from fighting life-threatening pneumonia and sepsis simultaneously landed Peterson in intensive care last summer.

Her father was, she said, 'near death.'

Friends and family describe Peterson's daily life as a grinding struggle. 

The condition is, as Peterson's daughter Mikhaila describes it, 'the worst thing I've ever seen anyone go through' and has got worse over the last few months.   

Peterson has long struggled with bouts of depression but his serious health issues began at the height of his fame in 2019, when his wife Tammy, now 60, was diagnosed with kidney cancer and he began increasing his anti-anxiety medication to cope.

Peterson himself described his condition at the time as 'dire' and confessed he had been left 'hoping that I would die.'

Most doctors say akathisia can be treated by slowly weaning patients off their medication.

But Peterson pursued bizarre medical treatments. Against his doctor's advice, Peterson flew to Moscow in January 2020 to be placed in a medically induced coma for more than a week to force a 'rapid detox.'

He had also adopted his daughter Mikhaila's radical red meat-only diet, which medical professionals warn against.

After a brief moment of improvement, October 2025 brought another blow to his recovery as he was rushed to hospital and his tour across North America and Europe was scrapped.

Fans continue to anxiously wait for Peterson's return to good health, and pour in messages of support, hope and love in the meantime.
