The outcomes confirmed that individuals who had been uncovered to extreme warmth earlier than they had been born suffered lifelong disturbing results.
Long run results
The evaluation discovered that almost all of research hyperlink long-term dangerous results to elevated warmth publicity throughout being pregnant. Particularly, researchers discovered associations with worse instructional efficiency and decrease revenue later in life.
