Whether you're heading away on holiday, working through the heat, or simply trying to stay comfortable at home, these practical tips from the National Pharmacy Association can help you stay safe this summer.
1. Stay out of the hottest part of the day
If possible, avoid spending long periods outside between 11am and 3pm, when the sun is at its strongest.
If you do need to be outdoors:
Stay in the shade where you can.
Wear loose-fitting, light-coloured clothing.
Protect yourself with a wide-brimmed hat and sunglasses.
Apply a high-factor sunscreen (SPF 30 or above).
Avoid strenuous exercise during the hottest part of the day.
2. Keep your medicines at the right temperature
Did you know that excessive heat can affect some medicines?
Most medicines should be stored below 25°C in a cool, dry place away from direct sunlight. Others, such as certain injections, may need to be kept in the fridge, so always check the label or patient information leaflet.
If you're travelling or you're unsure whether your medicines have become too hot, speak to your pharmacist before using them.
3. Stay hydrated
Your body loses more fluids during hot weather, even if you don't realise it.
Aim to drink water regularly throughout the day and don't wait until you feel thirsty. Lower-fat milk and sugar-free drinks are also good options.
Try to limit sugary drinks and alcohol, as they can contribute to dehydration.
4. Keep your home cool
A few simple changes can make a big difference:
Close curtains and blinds during the day to block out the sun.
Keep windows closed while it's hotter outside.
Open windows overnight or early in the morning when temperatures are cooler.
Electric fans can help if indoor temperatures are below 35°C.
5. Check indoor temperatures
High indoor temperatures can become uncomfortable, especially overnight.
Where possible, check room temperatures in the morning, during the afternoon and before bed. Ideally, rooms should stay below:
32°C during the day
24°C at night
6. Help protect your pharmacy team and medicines
Hot weather doesn't just affect patients—it can also impact pharmacy teams and stock.
Employers should encourage colleagues to:
Drink water regularly.
Take additional breaks if needed.
Work in cooler areas where possible.
Be mindful that prolonged PPE use may increase the risk of heat stress.
Remember to monitor medicine storage temperatures and follow manufacturer guidance to ensure medicines remain safe and effective.
7. Look out for others
Older adults, young children and people living with long-term health conditions can be particularly vulnerable during hot weather.
Take a few minutes to check in on elderly relatives, neighbours or friends to make sure they're keeping cool, staying hydrated and taking their medicines safely.
