Warm Weather Advice

Follow this helpful advice on the topics below to avoid being caught out by the sun and excess heat in warm weather conditions.


Sunburn

What to look out for – Sunburn (Symptoms)

  1. Reddened skin
  2. Pain in the area of the burn
  3. Blistering

What you need to do – Sunburn (Treatment)

  1. First, cover their skin with lightweight clothing and move them out of the sun and into the shade, or indoors if possible.
  2. Encourage them to frequently keep taking sips of cold water.
  3. Cool the skin by sponging it gently with cool water, or by soaking the sore skin in a cold bath or shower for no more than ten minutes. Repeat this if it helps ease soreness.
  4. If the burn doesn't blister, then it is mild. Apply calamine lotion or after-sun lotion to help soothe the skin.
  5. If the burn blisters or there is other skin damage, then it is severe and they’ll need to see a doctor.

 

Dehydration

What to look out for - Dehydration (Symptoms)

  1. Headaches and lightheadedness
  2. Dry mouth, eyes and lips
  3. Small amounts of dark urine
  4. Muscle cramps

What you need to do – Dehydration (Treatment)

  1. Help the casualty to sit down and give them plenty of water to drink.
  2. Giving them an oral rehydration solution to drink will help replace salt and other minerals which they’ve lost – you can buy this in sachets from any pharmacy.
  3. If they have any painful cramps, encourage them to rest, help them stretch and massage their muscles that hurt.
  4. Keep checking how they’re feeling – if they still feel unwell once they’re rehydrated then encourage them to seek further medical help as soon as possible.

 

Heatstroke

What to look out for - Heatstroke (Symptoms)

  1. Headache, dizziness and discomfort
  2. Restlessness and confusion
  3. Hot flushed and dry skin
  4. A fast deterioration in the level of response
  5.  A full bounding pulse
  6. Body temperature above 40°C (104°F)

What you need to do – Heatstroke (Treatment)

  1. Quickly move them to a cool place and remove their outer clothing but ensure you maintain their dignity.
  2. Then call 999/112 for emergency help.
  3. Help the casualty sit down, supported by cushions.
  4. Wrap them in a cold wet sheet and keep pouring cold water over it until their temperature falls to at least 38°C (or 100.4°F). Measure this with a thermometer under their tongue or under their armpit. Keep the sheet wet.
  5. If you can’t find a sheet, fan them or sponge them down with cold water to keep them cool.
  6. Once their temperature seems to have gone back to normal, replace the wet sheet with a dry sheet.
  7. While waiting for help to arrive, keep checking their temperature, as well as their breathing, pulse and level of response.
  8. If they start getting hot again, repeat the cooling process to lower their temperature.
  9. If they lose responsiveness at any point, open their airway, check their breathing and prepare to treat someone who’s become unresponsive.

 

Heat Exhaustion

What to look out for - Heat Exhaustion (Symptoms)

  1. A headache
  2. Dizziness and confusion
  3. Loss of appetite and feeling sick
  4. Sweating with pale clammy skin
  5. Cramps in the arms, legs and stomach
  6. Fast, weakening pulse and shallow breathing

What you need to do – Head Exhaustion (Treatment)

  1. Help the casualty to a cool place in the shade. Get them to lie down with their legs raised to improve blood flow to the brain.
  2. Then give them plenty of water to drink. You can also give them a sports drink like Lucozade or an oral rehydration solution to help replace the salt and fluid they have lost by sweating.
  3. Keep checking their breathing, pulse and level of response.
  4. Even if they recover quickly, suggest they see a doctor.
  5. If they seem to be getting worse, place them into the recovery position and call 999/112 for emergency help.
