- Conditions such as NYHA stage IV heart failure, advanced tumor disease, amyotrophic lateral sclerosis.
- Pronounced polyneuropathy of the hands.
- Skin eczema that does not allow to perform hot arm baths.
- Dementia or psychiatric diseases that would interfere with study conduct according to protocol.
- History of drug use or alcohol abuse at > 60 g/day in the past three months.

- Primary Outcome Measures
Name Time Method Do hot arm baths with a duration of five minutes lead to a reduction in diastolic blood pressure, compared to thermo-indifferent arm baths; measuresd five minutes after termination of the arm bath?
- Secondary Outcome Measures
Name Time Method a) Do hot arm baths with a duration of five minutes lead to a reduction in systolic and/or diastolic blood pressure, compared to thermo-indifferent arm baths; measuresd 1, 5, 10, 15, 30, 60 and 90 minutes after termination of the arm bath?<br>b) Do hot arm baths with a duration of five minutes lead to a change in heart rate, compared to thermo-indifferent arm baths; measuresd 1, 5, 10, 15, 30, 60 and 90 minutes after termination of the arm bath?<br>c) Do hot arm baths with a duration of five minutes lead to a change in skin temperature at hand and feet, compared to thermo-indifferent arm baths; measuresd 1, 5, 10, 15, 30, 60 and 90 minutes after termination of the arm bath?<br>d) Do the changes in blood pressure correlate with the changes in skin temperature at hand and/or feet?<br>e) Do the changes in blood pressure correlate with the preinterventional blood pressure?<br>f) Do the changes in blood pressure correlate with the participant's Body-Mass-Index (BMI)?
