Those who take certain medications for their mental health, such as some types of antidepressants and antipsychotic drugs, have been warned to stay extra alert during the ongoing heatwave and when in hot weather generally (such as while on holiday in a sunny countries). The ex-head of the Royal College of Psychiatrist, Dr Wendy Burn, has said that some medication may impact on body temperature control and have other side effects related to heat.

Dr Burn added that some medication may also cause people to sweat more than normal, make it more difficult to register when they're thirsty or leave their skin more sensitive to the sun causing a reaction (so it's more important than ever to use a high factor SPF, that has five stars on the bottle and offers both UVA and UVB protection).

Not all antidepressants have this side effect though, it's important to note, but evidence does seem to suggest there's a link between tricyclic antidepressants, antipsychotics and heat-related illnesses. Tricyclic antidepressants are not as regularly prescribed as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), which work by boosting the amount of serotonin in the brain.

Where possible, Dr Burn told the BBC, it's best if those on tricyclic antidepressants or antipsychotic medications spend plenty of time in the shade, drink lots of water and avoid alcohol and strenuous activity. She also advises taking cool showers and says to keep taking your medication regularly – do not suddenly stop whilst abroad or during the heatwave.

And lastly, if you have any concerns whatsoever with regards to the mental health medication you take (and how it might impact you during hot weather), it's always worth reaching out to your GP or popping into a local pharmacy for a chat with a medical professional.
