The Dangers of Working Up a Sweat

30/06/2009 By Peter Brooks

Dehydration risk for workers in summer heat wave warns  Water Wellpoint 

Experts are predicting a long hot summer and whilst many will relish the thought of a spell of warm weather, leading hydration expert, Water Wellpoint, is offering a few tips for commuters and other workers, to reduce the risk of heat related illnesses.

"Commuters - whether on the train, in their own vehicles or using underground systems - can suffer from long hot journeys and need to be aware of the risks of dehydration," explains Colin Wilson, Research Scientist, Water Wellpoint. “And it’s not just commuters who need to be aware of the risks, as the temperature rises.  People who work outside, such as gardeners, builders, police officers, firemen and professional drivers are also among the high risk groups in a heat wave."

Dehydration is the loss of water essential for body function, which occurs when more liquids and salts are lost than taken in. Thirst is a sign of dehydration, but by the time people are thirsty they are already mildly dehydrated and additionally some people confuse thirst with hunger. Water Wellpoint therefore advises people to top up on fluids throughout the day, especially when it’s very warm, to avoid risking heat exhaustion and heatstroke.  

“Heat exhaustion is caused by prolonged exposure to very hot temperatures or dehydration" continued Colin Wilson. “If someone becomes dangerously dehydrated, their body loses its ability to cool itself, which can affect a person’s vital organs.

“Someone with heat exhaustion may sweat excessively, feel faint, tired and have a headache. Left unchecked, heatstroke may occur and the person may become confused, disorientated and lose consciousness. Anyone exhibiting signs of heatstroke needs immediate medical attention. In a moderate heat wave, only high-risk groups such as the elderly and the very young may be affected, but in extreme heat, even normally fit and healthy people need to take extra care."

Wilson concludes, “‘A loss of more than 2% of a body’s fluids can cause as much as a 20% reduction in both physical and mental abilities. This means workers and especially those operating machinery need to top up their fluid intake to keep their mind on the job. Evidence shows that as the temperature rises the number of work related accidents also increases. Commuters should make sure they keep a bottle of water in the car or in their bag, in case they get stuck in traffic or suffer transport delays.

“We lose about half a litre of water every day just by breathing and more through perspiration, but in hot weather water loss will increase as the body strives to maintain a constant body temperature. It only takes a few simple precautions to avoid the effects of heat exhaustion, so we advise everyone to drink plenty of fluids to ensure a safe and enjoyable summer."

  • If possible, stay in the shade on hot sunny days
  • When working outside, wear a wide-brimmed hat and long, loose clothing
  • Drink lots of cool non-alcoholic drinks to replace lost fluids
  • Avoid alcohol if possible as it dehydrates the body
  • Reduce strenuous activity during the hottest part of the day where possible
  • Commuters should always travel with something to drink
    Using a wet flannel can help people to keep cool
  • Turn off non-essential lights and electrical equipment in the office to reduce build up of heat

Dehydration in the Elderly

Through Office Water Coolers commendable campaigning for better hydration in offices and schools, there has been a tendency to emphasise the need for hydration in working age adults and energetic young children. Perhaps it is pertinent to stress the need to educate the elderly in our society about the health benefits of keeping hydrated throughout the day. This need becomes even greater and more urgent when we consider that older people are more susceptible to dehydration because of specific physiological ...
