Summer, sun, heat

Summer is coming and with it the great heat. What can we do to protect ourselves and what helps if the cycle fails? How does one survive unscathed a car ride in the summer heat? The body expands the vessels in the skin at high heat and produces more sweat. The sweat on the skin surface evaporates, which cools the skin and helps to keep the body temperature constant despite the heat. In extreme conditions, especially in hot and humid weather, this cooling system can be overloaded and there are health problems.

Heat as a burden on the body

High temperatures and humidity, low air movement and heat cause a heat stress in the body. Inappropriate clothing, dehydration and the intensity and duration of physical activities add to the burden. It comes to regulatory disorders, that is, the body suffers from fluid loss and heat accumulation. Especially the elderly, patients with cardiovascular diseases or people with weak veins are at risk.

Since our body consists of 60 percent water, the addition of the heat-related fluid loss by the intake of at least 1.5 liters per day is vital. On hot summer days, however, the body may well need three to four times as much.

Signs of heat stress

  • Exhaustion, nausea
  • weak circulation (circulation weakness)
  • aggressiveness
  • Dazed and apathy
  • Headache and dizziness

Driving in the summer heat

Particularly stressful for the body is driving in high heat. Temperatures up to 70 ° C in the vehicle interior are not uncommon. During heat stress, the heart rate increases, it comes to premature fatigue and dizziness and thus prolonged reaction times. The result: the frequency of accidents increases by 20 percent in the heat.

Who goes on a long trip in the summer, should therefore often take small breaks and ventilate the car well. To keep the circulation going you should bring enough drinks along the way to get enough fluids (water).

What can you do? What helps with heat?

These 8 tips help you to cope better with the summer heat:

  1. Do you drink much! Normally we need about two liters of fluid per day; on hot days, it can be quite three to four liters of water.
  2. Eat light meals! Hard-to-digest, high-fat or rich meals are heavy in the stomach and additionally burden the circulation. You should therefore eat salad or fruit instead of roast.
  3. Replace salt and minerals! When we sweat a lot our body also loses important minerals and trace elements. These can be replaced by mineral drinks again.
  4. Airy clothing: For the summer, light, airy clothing made of natural fibers is recommended. This helps prevent heat build-up in the body. In direct sunlight especially children should wear a headgear.
  5. Avoid over-exertion! Do not burden your circulation with heavy physical work or exercise. Because every physical exertion increases the energy expenditure and thus the body heat which the body has to give off to the environment. It is better to do sports early in the morning or in the evening.
  6. Shut off the heat during the day: It is best to ventilate your apartment well in the mornings and evenings and close shutters and blinds during the day.
  7. Quick cooling: If you can not take it anymore, you can run cold water over the inside of your wrists or, even better, take a cold forearm and foot bath to cool off in summer. Due to the cold stimulus, the vessels are at least for a short time set closer - the cycle is strengthened again.
  8. Avoid alcohol: After drinking alcohol, the vessels in the body are even further set than they already are, that is, the circulation is still less blood available. In addition, the fluid excretion via the kidney is stimulated - the body loses even more fluid and minerals. Therefore, do not use alcoholic drinks during the hot days.
