Practical heatwave tips for people living with a terminal illness

With hotter summers and more frequent periods of extreme heat, many of us are concerned about how to stay cool and hydrated, but for those living with a terminal illness it can be more difficult, as the heat can worsen symptoms.

The impact of heatwaves on people with a life-limiting illness

People living with a terminal illness are already at risk of dehydration as they often find it hard to get enough fluid. Dehydration can contribute to constipation, causing extra discomfort. The heat can also make breathing more difficult. It is also common to sweat more or have a higher body temperature.

To help you minimise the risk of heat-related illness and stay as cool as possible, Sue Ryder's Chief Medical Director, Dr Paul Perkins, shares his top tips in this article.

Keep rooms as cool as possible

Close windows and blinds or curtains throughout the day to keep direct sunlight out, then open them when evening comes to let in the cooler air. Use fans as much as possible to keep the air in the room moving.

Stay hydrated

Sip small amounts of water throughout the day, or suck on ice if you find this easier. You can also use water-rich food such as watermelon, or ice lollies for extra hydration.

For those finding swallowing difficult you can follow the mouth care guidance from your palliative care team.

Target pulse points

You can quickly cool down by using a cool damp cloth or ice pack wrapped in a towel on your neck, wrists or ankles.

Wear breathable clothing

Dress in loose, lightweight, and light-coloured clothes made of natural fibres like cotton, which allow your skin to breathe.

Monitor symptoms

Be on the lookout for signs of heat exhaustion or heat stroke, which include dizziness, nausea, headache, or confusion. Seek immediate medical assistance if these occur.

Priority Services Register

The heatwave can increase the likelihood of power cuts.

If your care depends on electricity, like keeping medication in the fridge or your medical equipment is powered by electricity, make sure you join your energy provider’s Priority Services Register – this will ensure you are prioritised for reconnection.
