The houses were heated up in the recent heat wave. This is good for people with high blood pressure, especially if they don't like to exercise. This is suggested by a British study.
Blood pressure is affected by many factors. Stress, aging, lack of exercise and frequent consumption of alcohol and cigarettes - all of which make him increase. What few people know is that cold can also have this effect. This is confirmed by a study from England with data from more than 4600 adults, which has now been published in the "Journal of Hypertension".
Blood pressure and internal temperature measured simultaneously
The subjects were interviewed intensively about health, lifestyle and accompanying circumstances. They also received visits from nurses who measured their blood pressure at the same time as the temperature inside the room. The result: blood pressure was inversely proportional the lower the room temperature. And completely independent of the outside temperature, as the team led by Stephen Jivraj from University College London reports. This relationship was particularly evident when the respondents did little sport.
Low temperatures a cause of increased strokes?
Other researchers have also found evidence that higher temperatures can lower blood pressure in the long term. However, the effect for outside temperatures was only around half that for living rooms, according to the results of a study with around 115,000 participants from 16 countries. Jivraj and his colleagues note that individually measured values such as the ambient ambient temperature are not yet routinely recorded in research and diagnostics. They believe, like the authors of the international study, that the low temperatures could mean that more people die of stroke and heart disease in the winter months than in other seasons.
Warm interiors reduce the risk
Conversely, heating homes can decrease the winter increase in high blood pressure and the associated cardiovascular risks, especially for people who are not active in sports. "In addition to a healthy lifestyle, it could help to keep the houses a little warmer," the experts concluded. Although no concrete value could be derived from the study itself, the researchers recommend a minimum of 21 degrees Celsius. (fs)
