The oppressive temperatures of a heatwave can have far-reaching impacts, from risks to human health to destroying crops and increasing the risk of wildfires. In 2019, extreme heat is estimated to have caused the deaths of 356,000 people worldwide, according to one set of estimates, making it one of the most dangerous yet overlooked natural hazards. While there is still a great deal of uncertainty about toll that heatwaves take (the World Health Organization estimates 166,000 people died between 1998 and 2017, by comparison), there is little doubt that the number of people exposed to heatwaves around the world is increasing.
How do you stay cool in a heatwave?
It's crucial to stay cool in hot weather as it can have serious effects on your health. Fortunately, there are some simple steps you can take to find relief when the temperatures climb to uncomfortable levels.
You should also think twice before you open all the windows of your house to keep cool – if the temperature if higher outside than inside, you might lose a possible cool haven. Close the curtains in rooms where they face the sun instead.
One of the easiest ways to stay cool can be to take advantage of the temperature change in the air when water evaporates. Taking a cold shower or a swim can help you cool down quickly.
The human body's ideal temperature lies between 35.01C and 37.76C (95-99.9F), depending on how it is measured, although most medical experts accept an average of 36.8C (98.2F). When the surrounding air nears or exceeds this temperature, particularly when humidity is high, the body's ability to cool itself weakens.
How to stay hydrated in the heat
Keeping hydrated is a consistent public health message – for decades we've been urged by health authorities to consume as much as six to eight glasses worth of water a day, or 2-3 litres. But when temperatures rise, the need to keep fluids up is even more important.
Without a continual topping up of water (which makes up between 60% and 70% of our body weight) we start to dehydrate. The first reliable sign of dehydration is increasing thirst, when around 2% of body weight has been lost. Dehydration occurs more quickly with physical exertion or exercise. Even mild dehydration can cause fatigue and tiredness, and overheating as the body stops sweating to preserve water.
Many of us instinctively reach for a glass of water, but it may not always be the best option. Milk may, in some cases, be better, as it contains small amounts of salt and sugar which can be lost through sweating. Coconut water also contains vital elements lost through excess perspiration.
With almost no effort at all, pets manage to bring so much joy into our lives. They make us laugh, comfort us when we’re sick or upset, and are always there for us no matter what. It’s no wonder that an estimated 12 million British households choose to keep a pet.
Here's a few benefits to having your furry friends!
They keep you fit
All breeds of dog need regular, daily walks in order to stay happy and healthy, and so do we! However, we sometimes have the tendency to get a bit lazy – if that sounds like you, a dog is the perfect cure! They’ll be dragging you out the front door and making you run around the park each and every day. Yes, a dog is possibly the best personal trainer you could ask for.
They make sure you're never lonely
If you live by yourself, or your partner works different shift patterns to you, it can get awfully lonely at home – unless you have a pet, of course! Cats and dogs make great companions – they’ll always be waiting for you to come home and they’ll be happy to lend an ear should you want to moan about the awful day you’ve had. Plus, most of the time, they’re up for a snuggle on the sofa.
They make you feel safe
Not everyone likes being home alone, but having a cat or dog there can make you feel a lot safer. Plus, burglars are less likely to target a house that’s clearly home to a dog. Some breeds make excellent guard dogs and will even protect you when you’re out for a run or walk.
They can help you make friends
The pet owner community is an incredibly friendly one – you’ll often find that people will stop to talk to you about your dog in the park. Having a pet is a great way to meet new people and create bonds quickly, especially if you’re not too good at small talk. You never know, owning a dog may help you meet the love of your life!
They lower your stress levels
Modern life is stressful and high levels of anxiety can lead to numerous health problems. Luckily, pets can really help us relax – stroking your cat or simply watching fish swim around in a tank can make your worries melt away.
