Additional research is needed on future impacts of climate change on maternal, foetal and neonatal health. Maternal heat exposure is a risk factor for several adverse maternal, foetal and neonatal outcomes , including foetal growth  and congenital anomalies . There is very limited research on this subject, an exception being Zhang et al. , which projected a 34% increase in congenital health disease risk in the USA in 2025 and 2035 based on increased maternal extreme heat exposure.
