Active people

Those who work physically outdoors lose a significant amount of fluids and minerals in hot weather. The body heats up more quickly and intensely, especially in direct sunlight, high humidity, or with unsuitable clothing. This isn't just a concern for outdoor workers. Athletes and those engaged in leisure activities should also take precautions and reduce their exertion, for example, by shifting their activities to cooler morning hours.

Certain occupational groups are particularly vulnerable to heat, even though they work indoors. These are primarily professions where employees are required to wear protective clothing or uniforms (e.g., in industry and commerce). People who work in poorly insulated buildings or machine cabins are also at risk.

Muscle cramps, exhaustion, sunstroke, or heatstroke can occur when the body's fluid and electrolyte balance is disrupted. Physical overexertion in extreme heat can lead to circulatory collapse, cardiac arrhythmias, or, in extreme cases, death.

Heat protection

In addition to our general tips, you can protect yourself from heat in this way:

• If possible, shift physical exertion to the early morning or evening hours.
• Take regular breaks in the shade – even if you don’t feel acute discomfort. Avoid the midday heat: take a break or do lighter activities during this time.
• Drink small amounts every 15 to 20 minutes: water, isotonic drinks, diluted juices or broth.
• Wear light, light-coloured clothing and a hat with neck protection.
• Use sunscreen with a high SPF. Reapply regularly – especially if you sweat or come into contact with water.
• Watch out for warning signs and take symptoms seriously: act immediately if you experience cramps, headaches, nausea and hot skin
• To ensure occupational health and safety, the employer must take certain measures to protect against heat and UV radiation. Find out more about this and make your employer aware of their obligations.
