There is a higher risk of heart death for men in their early 60s on warmer summer nights, a new study reports.
Researchers found that 60 to 64-year-old men appear to have a higher risk when the mercury rises overnight in the summer months - but the same effect was not seen in women.
A 1C rise in night-time temperatures, compared with usual summer night-time heat, was linked to a 3.1 percent increased risk of cardiovascular deaths among men in their early 60s.
