Is it true that … you’re more likely to get sick when you’re stressed?
Stress releases hormones such as adrenaline and cortisol, which can suppress your immune system – but chronic concerns are more of an issue than short-term worries
TL;DR
- Stress hormones, including adrenaline and cortisol, can suppress the immune system.
- Short-term stress has a temporary effect on immune cells, returning to normal within an hour.
- Long-term stress significantly diminishes immune system effectiveness.
- Cortisol exposure makes immune cells less effective at fighting diseased cells.
- Practices like mindfulness and tai chi may reduce cortisol levels and benefit immunity.
- Proving the direct impact of stress-reduction strategies on immunity is difficult.
- Consult a GP if concerned about long-term stress.
