Dismissal who wish not to leave the campus, are not permitted in common rooms or classrooms where no
supervision is provided. Such students must go to the Library for Wise Freedom.
If a whole school event (such as One World Day or Japan Day) runs into period 8, Early Dismissal time
coincides with the end time of the whole school event.
Early Dismissal starts when all parents have given signed permission, on the date announced by the High
School Principal.

Managing excessive heat in school
August 9, 2018
During very hot and extreme heat conditions, students, faculty and the school community are at greater
risk of health problems. These can be specific heat-related illnesses or a worsening of existing medical
conditions. Health risks are greater when high temperatures combine with increased humidity.
Students take longer to adjust to hot environments than adults do, and their bodies reach core
temperatures much faster. Children’s bodies have greater surface area to body mass ratio, so they absorb
more heat on a hot day (and lose heat more rapidly on a cold day). Also, children have considerable lower
sweating capacity than adults, and so they are less able to dissipate body heat by evaporative sweating
and cooling.
Guidelines in Japanese schools:
When the temperature reaches:
35℃ and above: no sports activities
31℃: severe warning (no vigorous sports activities)
28℃: warning (rest more often)
24℃: caution (drink more water)
If the humidity is high, consider bringing up a level. e.g. if it is 31℃ with high humidity, no sports
activities.
Symptoms of HEAT STRESS to watch out for include:
Nausea;
Feeling faint;
Dizziness;
Loss of appetite;
