Study Links Climate Factors to Age of Menstruation
Imagine your body is like a plant, and climate is like the weather.
Scientists looked at how weather changes, like humidity and temperature, affect when girls start their periods.
They found that more humid weather is linked to periods starting earlier.
However, in some places, like Maharashtra, warmer weather seemed to delay periods.
This might be because the heat can be stressful for the body.
The study suggests that things like how much education a girl has, and access to nutrition and health care, also affect when periods begin.
Understanding this can help create better health programs.
Researchers examined the link between climate factors and menarche timing in India.
The study used data from DHS and climate data from NASA.
Higher humidity was associated with earlier onset of menstruation.
Higher temperatures correlated with delayed onset in most of India.
The study highlights the need for public health interventions.
