Hot weather and mental health medication
Heat can increase health risks for some people using medication for their mental health.
Medications that affect how the brain works, known as psychotropic medications (including hypnotics, anxiolytics, and antipsychotics) can impair the body’s ability to regulate temperature, making it harder for it to respond appropriately to heat stress. This is of concern particularly for individuals with schizophrenia or dementia.
People using these medications can be more vulnerable to heat-related health effects such as:
· heatstroke
· dehydration
· nervous system changes
· altered neurological function (such as confusion, agitation or disorientation)

If you experience any symptoms of overheating, such as dizziness, confusion, or unusual tiredness, it is crucial to rest, hydrate, and seek medical help if necessary. Always consult with your healthcare provider about any concerns regarding your medication during hot weather.
