A doctor has issued an urgent heatwave warning to anyone taking commonly prescribed antidepressants this summer, as soaring temperatures can pose serious risks to patients. The UK is currently experiencing a stark divide between north and south, with the southeast baking in a sweltering 32C, while the north contends with rain and considerably cooler temperatures of around 14C.
An Amber Heat Health Alert has been issued across England as an intense summer heatwave is forecast to strengthen further over the coming days. According to the Met Office, conditions are expected to become more settled heading into the weekend as high pressure begins building from the south.
“Sunny spells and feeling increasingly hot with temperatures well above the June average”, the weather agency said.
Millions of Britons taking widely used antidepressants have been cautioned that they could face a heightened risk of dehydration and heat exhaustion as temperatures continue to climb across the country. Selective Serotonin Reuptake Inhibitors, also known as SSRIs, are primarily prescribed to treat mental health conditions and function by increasing serotonin levels in the brain.
Approximately 8.7 million people in the UK were prescribed SSRIs from 2023 to 2024. Dr Rupa Parmar, GP and Medical Director at Midland Health, is sharing everything you need to know about taking the medication in the summer, reports the Mirror.
Dr Rupa Parmar said: “Excess sweat is one of the most common side effects of antidepressants. It’s most likely due to how the medication affects the hypothalamus, a brain part that plays an important role in regulating body temperature.”
She added: “Excess sweating can also cause dehydration, and there is a higher risk of heat exhaustion as heat tolerance is much lower. Signs of heat exhaustion include headaches, nausea, dizziness, weakness, irritability, and an increased body temperature.”
Why do people on SSRIs need to take extra care in hot weather?
Dr Rupa Parmar says: “For people on SSRIs, knowing the symptoms is crucial. If someone is experiencing heat exhaustion, get them out of the heat, keep them hydrated, and use cold compresses to help them cool down.
“Heatstroke occurs when the body is completely unable to regulate its temperature, which can lead to serious organ damage. It has the same symptoms as heat exhaustion, as well as confusion, seizures, and a rapid heart rate and breathing.

“The difference is that the symptoms of heat exhaustion usually subside within half an hour. If you are concerned someone has heatstroke, seek medical attention as quick treatment is necessary to prevent serious complications.”
How can you avoid health issues caused by hot weather?
The doctor says: “Your body loses a lot of water from sweating, so to combat dehydration, drink at least three litres daily to regulate a normal body temperature. Caffeine and alcohol also increase urine production, so avoid these during the heat and stick to water.”
Limit your time in direct sunlight as much as possible, restricting outdoor activities to the cooler periods of early morning and late evening, she advised. When venturing outside, opt for loose-fitting garments made from breathable materials such as cotton and linen to help prevent overheating.
“Cold compresses on the forehead and neck are also good for cooling down,” she added. Night sweats and hot flushes are also common while taking antidepressants, which can make sleeping particularly uncomfortable.
To keep your bedroom cool, ensure windows, blinds, and curtains remain shut throughout the day to block out warm air, opening them once temperatures outside have fallen at night.
She suggests: “If your room is under 35C, you could use a fan, and for the rest of your home, try to limit how long appliances like ovens and washing machines are on, as they can generate a lot of heat. If sweat is a problem getting in the way of your day-to-day life, it could be that your antidepressant isn’t right for you.
“SSRIs are rarely one-size-fits-all, and it can take a while to find the one that works the best for your needs and with minimal side effects. Never come off your medication without consulting your doctor first, and always talk to your GP if you’re experiencing any worrying side effects.”
