Why do you sometimes have cold hands in summer?

Man is a "warm-blooded animal" and therefore dependent on a constant body temperature. For this he has a complicated system for heat regulation - the temperature is constantly measured through the skin and inside the body. When cold, the temperature sensors give the signal to constrict certain vessels on the arms and legs and to reduce the circulation, so that important organs such as the heart, brain, lungs and kidneys remain adequately perfused.

Cold hands or feet - about every fifth woman suffers

The most common causes are circulatory problems or low blood pressure. Another possible cause is the so-called Raynaud's syndrome, in which the blood flow stops suddenly because of a vascular spasm in the fingers. This phenomenon has not yet been fully resolved by medicine. However, it is known that psychological stress and emotional stress, among other things, can trigger the vascular spasm.

Other causes of permanently cold hands and fingers can also be underlying disorders such as heart disease, diabetes or thyroid disease. Therefore, it is important to visit the doctor when cold hands or feet come back without external cause!

Which home remedies help against cold hands and feet?

  • Alternative baths à la Kneipp: the change between heating and cooling. Immerse forearms in warm water for 5 to 10 minutes, then quickly change to cold water for about 15 seconds. Repeat a total of two to three times, finish with cold water.
  • Watering with the hose: Simply unscrew the shower head. First a calf side with light water pressure from the foot up to the knee, then down the other side. Change between warm and cold two to three times. Also applies to forearm castings. Dry well.
  • Sauna: The sauna achieves similar effects. Subsequent cold showers promote blood circulation. If you have cardiovascular problems ask your doctor first.
  • Finger gymnastics: Gymnastics for the fingers brings the blood circulation of the hands on again. Simply stretch out your hands and bale your fist 20 times and open again. This promotes blood circulation and your hands are warm again.
  • Hot spices: Tabasco, red pepper, paprika and chilli promote blood circulation. But beware: the stomach needs it! If in doubt, rosemary will do. Ginger also has a heat-promoting effect.
