From sunscreen to staying cool: how to keep yourself and your family safe in the heat
School's out for summer and many Irish families will be jetting off to hotspots across Europe to hit the beach, soak up some sun and have some well-needed relaxation time. However, authorities across Europe remain on high alert as temperatures across the Continent soar in the first heatwave of the summer. On Friday, Spain's state meteorological office, Aemet, issued a heat warning, saying temperatures could reach 42 degrees. While it is easy to get caught up in the excitement of heading off on holiday, it's important to stay vigilant when heading to countries with extreme temperatures. Staying safe in the sun: tips to protect yourself and your family READ MORE Between 11am and 3pm are generally the hottest hours of the day. Try to avoid going out during this time. If you do find yourself in the sun during these hours, make sure you continue to top up on the sunscreen. The HSE recommends you regularly apply a broad-spectrum water-resistant sun cream. Broad spectrum means the sunscreen protects against ultraviolet (UV) rays, which can damage the skin. Adults should use an SPF (sun protection factor) of at least 30 and children should use an SPF 50. Sun cream should be applied 20 minutes before going outside, and every two hours afterwards. Make sure to reapply after swimming or if you have sweated throughout the day. Keep an eye on the UV index, which tells you how strong the sun's UV rays are each day. UV rays can damage skin and increase your risk of skin cancers. Take extra precautions when the UV index is three or above. [ European heatwave: Special heat warning in Spain; temperatures to reach 40 degrees in many countries ] Sun cream alone does not give 100 per cent protection – so be sure to pack sunglasses that offer protection against UV rays and to have a broadbrimmed sun hat to protect both your head and face. As much as you might want to return from your trip with a sun-kissed glow, it really is best to get it from a bottle. A tan from the sun is a sign that your skin has been damaged. Such damage never goes away, even when it fades. When inside, be sure to switch off lights and appliances when not in use as these generate heat. During the day, keep windows that face the sun closed. At night, when the temperature drops, keep them open to stay cool while you sleep. Staying hydrated is important in any weather, but especially during hot days. Rather than waiting until you're thirsty to drink, sip water throughout the day. Most adults need about two litres of water every day to stay hydrated. Watch out for the symptoms of dehydration. These can include feeling lightheaded or dizzy, tiredness, a dry mouth, lips or tongue and urinating less throughout the day. Dehydrated babies may have fewer wet nappies than usual. Children do not sweat as much as adults, so it is harder for them to stay cool. Don't leave children in parked cars, even if the window is open. Parked cars can heat up by at least 10 degrees in just 10 minutes. Watch out for signs of heat exhaustion, such as body cramps, lack of appetite, headaches and vomiting. Heat exhaustion can turn to heatstroke if the body cannot cool down. If you think your child may have heat exhaustion, sponge their skin will cool water and place cold packs around their armpits and neck. If you or your child is severely dehydrated or displaying symptoms of heatstroke, you may need to go to the hospital. For those travelling to Europe, don't forget your European Health Insurance Card, which covers you for free or reduced cost healthcare. Are you sweltering in continental Europe?

Night-time temperatures are not expected to fall below 12 degrees on Friday, although isolated showers are possible in parts of Ulster and Leinster. It will be mild, with temperatures not falling below 12 to 17 degrees. Met Éireann meterologist Holly O'Neill said: 'it is set to be a very warm and hot day today with long spells of sunshine across the country.' READ MORE She said the authority's ultra violet index (UV), which predicts danger of damage to skin from sunburn, is high and warned of the need for people to protect themselves by being 'sun smart'. Scattered showers are expected on Saturday, with some heavy and possibly thundery at times, but highest temperatures are expected to be up to 25 degrees. It is forecast to be warmest across the eastern half of the island, all in a light to moderate southwest wind. The hot spell may break in some areas on Saturday night as unsettled weather moves in from the Atlantic but many places will still enjoy long spells of sunshine. A heavier and more persistent band of rain will move in from the west later on Saturday night but temperatures should not fall below 12 to 15 degrees, in a mainly light to moderate southwest breeze. A bright start is expected to Sunday morning but outbreaks of showery rain will move in from the west with sunny spells and scattered showers to follow. It is expected to be fresher and breezier with highest temperatures of 15 to 20 degrees, warmest in the east, all with rather brisk westerly winds. The outlook for Monday, however, is for further change. There will be a bright start to the day with isolated showers, followed by outbreaks of rain later on. Highest temperatures are expected to be in the 13 to 18 range, feeling cooler in the north. By Tuesday the sunny conditions will be over, with cloudy conditions, rain and drizzle almost everywhere. A few brighter spells may break through in the north and west at times. Highest temperatures of 15 to 19 degrees, in mainly moderate to fresh west to southwest winds, are expected.
