The first objective of H3Sensing is to investigate outdoor environmental, building, dwelling, situational, and behavioral determinants of objectively assessed personal heat stress over daily movements during warm periods.
The second aim is to investigate how these heat stress determinants and momentary and cumulated heat stress itself are related to physiological indicators of heat stress, sleep, thermal discomfort, and well-being.
Person aged between 30-64 years
Person living in the Ile-de-France
Person subject to a legal protection measure (safeguarding of justice, curatorship, guardianship)
Person deprived of liberty by a judicial or administrative decision,
Person with a major functional limitation affecting their spatial mobility
Person unable to complete a questionnaire
The study population is a sample recruited through internet advertisement, residing in the Grand Paris, in warmer or cooler areas and in different types of dwellings. Quota sampling is applied in this research.
Case-crossover
Prospective
Not listed
Ambulatory blood pressure
Ambulatory blood pressure measured with a bracelet
Skin temperature
It is measured with a bracelet, in degrees. It provides important information on the interaction of the body with the heat environment.
Accelerometry outcomes: total sleep time, sleep efficiency, and wake after sleep onset
These three accelerometry outcomes will be derived from a bracelet. Total sleep time is in hours and minutes. Sleep efficiency is a percentage. Wake after sleep onset is in minutes.
Personal heat stress measured with the Universal Thermal Climate Index
This secondary outcome will be measured with a unique indicator called the Universal Thermal Climate Index. Although it is based on 4 parameters measured with wearable sensors (air temperature, humidity, radiant temperature, and air flow), it is measured in degree Celsius (so with a unique unit).
