Indoor temperature can affect your blood pressure, says study

According to a recent study published in the Journal of Hypertension, one can manage hypertension by turning up the thermostat. The researchers at the University College London has compared the blood pressure readings of people in their own homes with temperature readings and the results were the lower indoor temperatures were linked to higher blood pressure.


Doctor Stephen Jivraj said, “Our research has helped to explain the higher rates of hypertension, as well as potential increases in deaths from stroke and heart disease, in the winter months, suggesting indoor temperatures should be taken more seriously in diagnosis and treatment decisions, and in public health messages.”


The doctor further said, “Among other diet and lifestyle changes people can make to reduce high blood pressure, our findings suggest that keeping homes a bit warmer could also be beneficial.”


The researchers have found that every one degree Celsius decrease in indoor temperature was associated with a rise of 0.48 mmHg in systolic blood pressure and 0.45 mmHg in diastolic blood pressure. Ideal blood pressure is considered to be between 90/60 mmHg and 120/80 mmHg. Blood pressure readings consist of two figures given together: systolic pressure, the force of the heart’s contraction, and diastolic pressure, the resistance in the blood vessels.


The research team found the effect of indoor temperature on blood pressure was even more than the people who do not exercise regularly, suggesting that physical activity could mitigate the risk of living in a cool environment and that people who do not exercise need to keep warmer to manage their blood pressure.
