As part of your general health and safety duties, assess whether anything in the work environment could be making symptoms worse — for example uniform material and fit, workplace temperature and ventilation, access to cold drinking water, and whether there's somewhere suitable to rest if needed. Review risk assessments regularly, including for employees working from home.
