I am currently collecting data for Open Assistant. The user provided the following prompt: `Can meditation help with physical pain relief?`

I need to rank the following assistant answers from best to worst:

a)
```
Research has shown that meditation and mindfulness practices can effectively reduce chronic pain, including headaches, low back pain, and arthritis. By reducing stress and anxiety and promoting relaxation, meditation can help to alleviate physical pain and discomfort.

Additionally, some studies have shown that meditation can help to rewire the brain and reduce the perception of pain, leading to long-term pain relief.

It's important to keep in mind that while meditation can be a helpful complement to traditional medical treatments, it is not a replacement for medical care and should not be used as the sole treatment for any medical condition, including physical pain.

b)
```
Yes, meditation can cause the brain’s sensitivity to pain to reduce. It can also increase a person’s ability to cope with pain.
```

c)
```
Yes, meditation can help with physical pain relief. Research has shown that regular meditation practice can help to reduce chronic pain, decrease inflammation, and improve physical sensations. This is thought to occur because meditation has the ability to change the way the brain processes pain signals and can help to reduce stress and anxiety, which are often contributing factors to chronic pain. Additionally, meditation can help improve overall relaxation, which can also reduce the severity of physical pain.
