Frequently Asked Question

A person’s body temperature says a lot about their health. For example, a fever is the most common form of increased body temperature.

Reasons for measuring body temperature

Measuring body temperature is very important in medicine. A number of diseases are characterised by a change in body temperature. With other illnesses, the course of the disease can be followed by measuring body temperature. This allows the doctor to analyse the effectiveness of treatments based on body temperatures.

A fever is the reaction to a disease-specific stimuli. The body changes its normal temperature to support the body’s own defence mechanisms. Fever is the most common form of disease-related (pathological) increase in body temperature.

Important information for taking the measurement

The measured body temperature always depends on which part of the body the measurement was taken from. For this reason, and contrary to popular opinion, there is no general normal temperature.

The body temperature of a healthy person also changes throughout the day and depending on what activities they undertake. With a rectal temperature measurement, the body temperature is normally 0.5 degrees Celsius higher in the evening than other times of the day for physiological reasons. In addition, body temperature is increased by any physical exertion.

A fundamental distinction is made between:

Core temperature: made by inserting the thermometer into a bodily orifice and provides the temperature of the mucous membrane. Surface temperature: measured on the surface of the skin and is made up of the temperature inside the body and the ambient temperature.

Elevated blood pressure can be a health risk. The following summary gives you an overview on what causes it and what you need to know about high blood pressure.

1. What is high blood pressure?

Arterial blood pressure is caused by the pressure of the blood against the arterial walls. The heart acts as a pump and each beat causes an increase in the arterial pressure.

There are two different pressure values at the exit from the heart:

The highest pressure value is the systolic blood pressure - corresponding to the contraction of the heart which pumps blood into the arteries.

The lowest value is the diastolic blood pressure - corresponding to the pressure of the blood between two heart contractions.

2. How is blood pressure measured?

Arterial blood pressure is measured using an inflatable cuff. This is slipped over the arm or wrist. Measurement should only take place after five minutes of sitting quietly or lying down. The device measures the pressure in the arm artery while the air is released from the cuff.

The measured blood pressure value includes two numbers:
  • systolic blood pressure
  • diastolic blood pressure
Different devices can be used:
  • an automatic blood pressure device with value display
  • a blood pressure device with mercury
  • a blood pressure device with a sub-divided scale

3. What is hypertension?

High blood pressure is when the blood pressure is measured with a value of 140/90 mmHg or above. Blood pressure is measured at a state of rest in a doctor’s office.

The two measured values correspond to:
  • systolic blood pressure of 140 mmHg
  • diastolic blood pressure of 90 mmHg
  • Taking blood pressure measurements regularly can detect diseases, even if they go on for long periods of time without showing obvious symptoms.

4. What causes high blood pressure?

In most cases, high blood pressure occurs for no discernible reason - so-called essential hypertension. However, a small number of people with high blood pressure have anomalies in their kidney or adrenal gland function. In this case, the condition is called secondary hypertension.

There are many factors that encourage the appearance of high blood pressure – for example:
  • pigmented skin
  • genetic factors
  • age
  • being overweight
  • consuming too much salt and alcohol

However, it has been found that the occurrence of arterial hypertension can be limited or delayed in certain patients. The most important preventative measures are lifestyle factors - these include sports, consuming less salt and alcohol, and losing weight.

5. What are the consequences of high blood pressure?

Arterial blood pressure which is too high primarily affects the blood vessels. The vessel walls become stiffer and thicker. In the long-term, the impact can be severe - for example on the heart, brain or kidneys.

Possible effects of arterial hypertension:
  • serious risk factor for cardiovascular diseases
  • the most common results of untreated hypertension are heart attacks and strokes
  • kidney failure, angina pectoris, paralyses, loss of speech and dementia are also possible

It is important that you control your blood glucose levels as well as you can as too high sugar levels for long periods of time increases the risk of diabetes complications developing. Diabetes complications are health problems which include:

  • Kidney disease
  • Nerve damage
  • Retinal disease
  • Heart disease
  • Stroke

This list of problems may look scary but the main point to note is that the risk of these problems can be minimised through good blood glucose level control. Small improvements can make a big difference if you stay dedicated and maintain those improvements over most days.

Your cuff might be too small for you. A cuff that is too small yields a measurement that is higher than the correct blood pressure. Be sure to check that you are using the correct cuff size before taking your blood pressure. Please refer to User Manual for details. If your measurements still seem high, please consult your physician.

Normal body temperature is specific to an individual. It is recommended that several readings are taken while healthy to establish an individual's normal baseline temperature.

The following ranges are generally considered normal temperature ranges. For specific questions regarding your individual health, please contact your healthcare provider.

  • Axillary (armpit): 94.5 - 99.1F
  • Oral (mouth):
  • Babies (0-2)-- 97.5-100.4F,
  • Children (Ages 3 to 10)-- 97.0-100.4F,
  • Young People and Adults (Ages 11 to 65)-- 96.6-99.7F,
  • Elderly People (Over the age of 65) -- 96.4-99.5F.
  • Rectal (Rectum) to age 5: 97.9 - 100.4F,
  • Ear: 96.4 - 100.4.

An individual's blood pressure varies greatly from day to day and season to season. Normally, blood pressure rises during work or play and falls to its lowest levels during sleep. The best way to get consistent readings is to monitor your blood pressure at least once a day, at the same time so that you can minimize the effect that external factors have on the reading.

Also please be sure to consult your physician immediately if you have any doubt about your readings.
