This month, as summer (hopefully!) heats up in the UK and we can look forward to warmer days and balmy evenings, we’re taking a look at the less welcome effects of the sun - namely sunburn, heat exhaustion and heat stroke.
Of course, many of our clients face challenges involving hot weather and the sun routinely. The majority of Superyachts and Cruise ships spend most of the year in the world’s warmer locations and our Commercial shipping colleagues can often see all four seasons in a single trip, or even day! So knowing the dangers of hot weather, exposure to the sun and what to do if it goes wrong can be really important.
Sunburn
Sunburn happens when the skin is exposed to direct sunlight for too long. The skin becomes red, hot and sore but can usually be self treated. The skin may flake and peel, but should get better within 7 days. It’s something that most of us have experienced at least once, but we don’t generally take it seriously.
As with most medical conditions, prevention is better than cure. So slap on some sunscreen, wear a hat, drink lots of water and keep exposed areas covered with light clothing. You can also have aftersun lotion on standby just in case.
But, if you notice sunburn symptoms, you should get out of the sun and cool the skin with water or a damp towel. Topical aftersun lotions/sprays and aloe vera can help soothe the soreness and you will need to drink plenty of water as you are likely to be a little dehydrated.
Over the counter pain relief such as paracetamol or ibuprofen can help and while the skin is healing, make sure you don’t expose it to direct sunlight again.
Never use petroleum jelly, ice or ice packs on sunburnt skin and don’t wear tight fitting clothes.. Leave blisters intact and try not to scratch or remove peeling skin… despite the overwhelming temptation!
If the sunburn is severe, you may need to seek medical attention and remember that too much or regular exposure to the sun causes damage and death to skin cells and can also lead to skin cancer.
Heat Stroke and Heat Exhaustion occur when the body’s temperature rises above a normal level of around 37 degrees centigrade. Both conditions can involve multiple body systems. Heat Exhaustion can develop into Heat Stroke and eventually lead to death if left untreated.
Heat Exhaustion
Heat Exhaustion occurs when body temperature reaches 38-40 degrees centigrade. It’s not normally too serious and symptoms should reverse within about 30 minutes.
Symptoms include:
- Headache
- Pale and sweating
- Nausea and vomiting.
- Loss of appetite.
- Cramps in the arms, legs and abdomen.
- A fast, weak pulse.
- Rapid breathing rate.
- Feeling cold, but hot to touch.
There are a number of things you can do to help someone suffering from heat exhaustion:
- Move them to a cool place.
- Get them to lie down and raise their feet slightly.
- Remove any excess clothing.
- Get them to drink plenty of water. Sports or rehydration drinks are good too.
- Cool their skin – spray or sponge them with cool water and fan them. Cold packs around the armpits or neck are good too.
- You should see a noticeable improvement within around 30 minutes. But if not, consider whether the Heat Exhaustion has advanced to Heat Stroke and follow the suggestions below.
Heat Stroke
Heat Exhaustion can lead to Heat Stroke if nothing is done to reduce the temperature. It’s considered to occur when the body's temperature exceeds 40 degrees centigrade.
At the stage of Heat Stroke, the body loses the ability to manage its own temperature and this means urgent ‘aggressive’ action is needed to bring the temperature back down.
Symptoms of Heat Stroke include:
- Still feeling unwell after 30 mins of resting in a cool place and drinking plenty of water.
- Throbbing headache.
- Flushed, hot and dry skin.
- Not sweating despite feeling too hot.
- Rapid breathing or shortness of breath.
- Nausea and vomiting.
- Confusion.
- Seizures.
- Dizziness, loss of consciousness (fainting).
- Not responsive.
If Heat Stroke is suspected or identified, urgent action is needed to reduce the temperature. So in addition to the suggestions for Heat Exhaustion above, you could:
- Move into a shaded area.
- Cool rapidly using whatever is available. Remove clothing and wrap in a cold, wet sheet. Keep it wet.
- Continual cooling with a sponge.
- Place in a cool shower.
- Spray with cool water.
For either Heat Exhaustion or Heat Stroke, if the casualty loses consciousness, put them in the recovery position. Stay with the casualty and run through your normal DR (c) ABC DE assessment.
