Among the many dramatic effects of global warming, there is also the alteration of our sleep quality.
Many studies have shown that poor sleep quality can have serious consequences on our health.
According to data collected between 2015 and 2017 by Danish and German researchers, above 30°C, we would lose an average of 14 minutes of sleep per night, or about 44 hours of sleep per year.
The higher the temperature, the lower the probability of getting 7 hours of sleep.
And by 2100, we could lose between 50 to 58 hours of sleep per year.
This is due to the difficulty in falling asleep and waking up earlier under these conditions.
People over 65 years old are the first victims of hot nights since their bodies are less able to regulate heat (they are twice as likely to see an impact impact on their sleep).
Women are then the most affected by this phenomenon because their body temperature drops earlier in the evening compared to men.
They therefore suffer from high environmental temperatures at bedtime.
Finally, there are disparities according to geographical areas.
Low-income countries are 3.5 times more affected by rising temperatures since they are less equipped in terms of ventilation or air conditioning systems.
As a reminder, the ideal temperature to fall asleep is 66°F.
