Certain factions of the population could be at risk during the summer months, because of the variability in temperature.
Research from Harvard School of Public Health (HSPC) has revealed that older adults with chronic medical conditions could have their life expectancy shortened by the day-to-day variations in the weather.
This the first study to examine the long-term effects of climate change on life expectancy and could have important ramifications for Britons.
The UK's fluctuating temperatures during the summer means that many people struggle to adjust to the ever-changing climate.
Those with diabetes, heart failure, chronic lung disease, or those who have survived a previous heart attack are specifically at risk of an increase in mortality.
Antonella Zanobetti, senior research scientist at the Department of Environmental Health at HSPC and lead author of the study, commented: "The effect of temperature patterns on long-term mortality has not been clear to this point.
"We found that, independent of heat waves, high day to day variability in summer temperatures shortens life expectancy."
