The Federal Centre for Health Education has compiled information on heat and health in old age. Among other things, it states:
"Bright sunshine and rising temperatures are part of summer for most people. However, it's not just UV radiation that can be dangerous to our health, but also the heat, especially during prolonged periods of heat. For older people in particular, heat can be a major strain on the body.
How well our body can "handle" heat depends, among other things, on our age, fitness and state of health. If we get too hot, we start sweating, our blood pressure drops and we feel exhausted more quickly. However, prolonged exposure to direct sunlight can also have serious health consequences. Most people have probably experienced sunburn or swollen legs on hot days. However, some health problems caused by heat, such as heat stroke, can be life-threatening.
Correct behaviour can help to prevent heat-related health problems. The following tips for everyday life can help you do this:
- Drink enough (about 2 to 3 litres throughout the day), even when you are out and about. Water, unsweetened teas or juice spritzers (1 part juice and 3 parts water) are best. The drinks should not be ice cold.
- Eat vegetables and fruit rich in water, leafy salads and light meals.
- Cool your body, e.g. with damp cloths, foot baths, water spray, showers.
- Try to keep your home cool, e.g. by closing shutters and curtains. If possible, only ventilate at night or in the morning and evening hours. The room temperature should remain below 26 degrees Celsius.
- Move shopping, appointments and errands to the cooler morning hours.
- Avoid direct sunlight.
- Dress as lightly and airily as possible and remember to wear a hat and sun cream.
- Talk to your doctor about what you should be aware of when dealing with high temperatures, especially if you have a medical condition or are taking medication. Ask relatives and neighbours for help, for example with shopping or gardening.
- If you have the opportunity, move to a cooler room to sleep. A thin duvet (possibly just the cover), light sleepwear and, for example, a hot water bottle filled with cold water will also help you to get a good night's sleep.
