This document discusses issues with the UK NICE guidelines for Myalgic Encephalomyelitis (ME) regarding graded exercise therapy (GET). It notes that an ME Association survey found 74% of patients reported worsening symptoms from GET. The guidelines recommend exercising at 50-70% of maximum heart rate, but doing daily activities often exceeds this for ME patients. Using a heart rate monitor, the author found that activities like showering, writing emails, or making a drink increased their heart rate beyond the recommended zone. While NICE suggests heart rate monitoring, many doctors do not advise patients to use monitors. Properly adhering to heart rate limits with monitoring shows the significant differences between what exercise means for healthy and ME patients.
