Physics Girl's Medical Mystery

Summary

Physics communicator Diana Cowern describes becoming severely ill after contracting COVID during her honeymoon. After initially recovering from typical symptoms, she developed profound fatigue, brain fog, nausea, headaches, and extreme sensitivity to light and sound. Her heart rate sometimes fell to around 30 beats per minute, so her partner monitored it with an alarm-equipped heart-rate monitor.

Despite her worsening condition, medical tests did not reveal an obvious cause, and she was twice turned away from the emergency room. Her story highlights how post-infectious illnesses—including long COVID and chronic Lyme disease—can remain poorly understood. The subtitles cite estimates that these conditions may affect up to 10% of Americans, while noting that no treatment has been approved specifically for long COVID.

Cowern tried treatments not specifically approved for long COVID, which helped her regain some abilities, including reading, listening to music, and eventually making a science video. She says she has improved but remains at roughly 30–40% of her previous capacity.

Scientific Concepts and Phenomena

• Post-infectious chronic illness: Some people do not fully recover after COVID or other infections, for reasons scientists do not yet fully understand.
• Long COVID symptoms: Cowern’s reported symptoms included severe fatigue, cognitive difficulties, sensory sensitivity, nausea, headaches, and an unusually low heart rate.
• Treatment uncertainty: The video describes a lack of approved treatments specifically for long COVID and says Cowern tried treatments not specifically approved for the condition.
• Other science featured in Cowern’s videos:
  • The moving stones of Death Valley.
  • Light produced in the Sun’s core taking hundreds of thousands of years to reach the Sun’s outer region.
