What happens in your body when you take painkillers after training?

Do your legs feel like lead after your last workout? The soreness is real and you're thinking about popping a painkiller? Before you do, you should know what's really going on in your body.

Why is inflammation not necessarily bad?

Many people immediately think of inflammation as something negative. But it's actually a crucial part of your healing process. Your body uses it to break down damaged cells and fight off potential pathogens. Moderate inflammatory reactions can even support your recovery after training.

Can painkillers slow down your recovery?

Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen relieve pain by suppressing the inflammatory response. This feels good in the short term, but can delay the healing process. Less pain does not automatically mean that your muscles regenerate faster - sometimes the opposite is the case.

What really helps against sore muscles?

Exercise! A relaxed walk can promote blood circulation, soothe sore muscles and speed up your recovery - without any side effects. Of course, if the pain is severe, painkillers may be necessary. But if it's just normal muscle soreness, give your body what it really needs: gentle exercise instead of pills.
