Scientists say rising temperatures may be quietly speeding up the body’s biological clock.

New research shows that long-term exposure to extreme heat doesn’t just cause discomfort—it could actually make you age faster at the cellular level. Frequent days over 90°F are now linked to DNA changes and faster tissue decline, with effects similar to heavy smoking or drinking.
The findings suggest that as climate change intensifies, the heat outside might be silently rewriting how quickly we grow old.
