Stay cool in a heatwave

You should always try to avoid getting too hot in a heatwave. Hot weather can lead to dehydration, overheating, heat exhaustion and heatstroke.

To keep cool you should stay out of the heat by avoiding going out at the hottest time of day (usually between 11am – 3pm), avoid doing strenuous outdoor activities such as sport or gardening, stay inside in the coolest rooms in your home, take cool showers and baths and drink cold drinks regularly, avoid alcohol and caffeine.

Taking these steps will help prevent health complications during hot weather.

Seek help from a GP or call NHS 111 if someone is feeling unwell and shows signs of:

  • breathlessness
  • chest pain
  • confusion
  • intense thirst
  • weakness
  • dizziness 
  • cramps which get worse or don't go away 

Get the person somewhere cool to rest. Give them plenty of fluids to drink. 

Find out about Heat Exhaustion and Heatstroke from NHS Choices.

Hay fever

Hay fever affects up to 1 in 5 people in the UK at some point in their lives. A lot of people find their symptoms are at their worst in the summer, but there are three different types of pollen that can cause hay fever from March to September.

Most people find that they can get relief from their symptoms with treatment. Hay fever can often be controlled with over-the-counter medication from a pharmacist, but if your symptoms are more troublesome, it’s worth speaking to a GP as you may require prescription medication.

You can also reduce symptoms by wearing wraparound sunglasses to protect your eyes from pollen while outdoors, taking a shower after being outdoors, staying indoors when the pollen count is high and applying a small amount of Vaseline (petroleum gel) to the nasal openings to trap pollen grains.

You can get the pollen forecast from the Met Office.
