What condition does Hafthor Bjornsson have?
According to Wikipedia, Bjornsson was diagnosed with acromegaly in 2017, a hormonal disorder caused by a benign pituitary tumor that leads to excessive growth hormone production. The condition explains his towering frame — but it also brought a facial droop that fans noticed.
Why does Thor’s face droop?
Bjornsson has stated that the droop is due to Bell’s palsy, a temporary facial paralysis that can occur after acromegaly treatment. The condition is not permanent and has improved over time.
How heavy was Thor at his heaviest?
His competition weight has peaked at around 205 kg (452 lb), according to BBC News (UK broadcaster). At that weight, he set the deadlift record of 501 kg.
The same condition that helped Bjornsson grow to 206 cm also threatened his health. Treating the tumor may have caused his Bell’s palsy, but it also allowed him to continue competing at the highest level.
The implication: Bjornsson’s health challenges have shaped his career as much as his strength.
When did Hafthor Bjornsson lose his daughter?
In 2021, Bjornsson and his wife Kelsey Henson suffered the loss of their newborn daughter. The tragedy was a deeply personal moment that he shared with his followers.
How many children does Hafthor Bjornsson have?
According to Wikipedia, he has one living son, Stormur, born in 2020, and a daughter who passed away in 2021.
How old is Hafthor’s son?
Stormur was born in 2020, making him around 4 years old as of 2024.
The pattern: Personal tragedy has been a recurring theme in Bjornsson’s life, but he continues to move forward.
Who is the strongest man on Earth?
The title “World’s Strongest Man” is awarded annually, and Bjornsson won it in 2018 (World’s Strongest Man (strength competition)). But the debate over who is truly the strongest often comes down to the deadlift record.
Is Thor stronger than Eddie Hall?
Eddie Hall set the 500 kg deadlift record in 2016. Bjornsson broke it on 2 May 2020 with 501 kg (1,104 lb) at his home gym in Reykjavík, Iceland, under the observation of strongman referee Magnús Ver Magnússon (BBC News (UK broadcaster)). The two settled their rivalry in a boxing match in 2022, which Bjornsson won by unanimous decision.
Six stats, one contrast: the two men’s size and records are nearly identical, but their paths diverged.
| Metric | Hafthor Bjornsson | Eddie Hall |
|---|---|---|
| Height | 206 cm (6 ft 9 in) | 190 cm (6 ft 3 in) |
| Competition weight | 205 kg (452 lb) | 180–190 kg (396–419 lb) |
| Deadlift record | 501 kg (1,104 lb) | 500 kg (1,102 lb) |
| World’s Strongest Man titles | 1 (2018) | 1 (2017) |
| Boxing match result (2022) | Won by unanimous decision | Lost |
Bjornsson’s 1 kg advantage came with a weight gain that pushed his body to extremes. For fans, the rivalry shows that “strongest” depends on the metric — and the day.
What this means: The debate over who is the strongest will continue, but Bjornsson’s records speak for themselves.
What is Hafthor Bjornsson’s net worth?
His net worth is estimated at $3 million, according to Wikipedia (reference site). The bulk of his income comes from strongman competitions, but he also earned from his role as The Mountain in Game of Thrones, endorsements, and his boxing match against Eddie Hall.
