REVEAL the HEALTH EFFECTS of LIGHT
Reveal the effects of light exposure on human health
via epidemiologic data science
Do you know that
light affects your health?
We live under the control of the biological rhythms.
Recent studies have shown that disturbances
in the biological rhythms cause various diseases.
Importantly, light exposure has a big impact on
the biological rhythms.
We actually measure the amount, quality,
and timing of light that people are exposed to,
and scientifically analyze the relationship
with various health data.
We have published many research results so far,
and this website introduces our large-scale epidemiological research.
In addition, I will also introduce interesting research
that I am involved in as a co-researcher.
