Do you notice that it is hard to sleep on hot humid nights? Do you find yourself tossing and turning struggling to nod off and casting aside your duvet? Well this is all to do with how a good night’s sleep is dependent on temperature and particularly our core temperature which needs to be within a certain range to ensure we are comfortable.
Studies have shown that our core body temperature falls by as much as 2 degrees during sleep which means our temperatures drop from 37 degrees down to a range of between 35 and 36 degrees.
To achieve this important drop in core body temperature, the surrounding environment must also be kept as a temperature that allows the body to cool down. If this external temperature is raised during heatwaves and the accompanying hot sticky nights, then this is the reason why it becomes so difficult to sleep or at least sustain sleep for a full night.
While there are plenty of studies showing that excessive light can have an impact on quality and quantity of sleep, temperature is just as important. So to avoid discomfort, care should be taken to select bedding that helps regulate temperature such as cotton sheets rather than duvets.
When it comes to mattress choice if you suffer in the heat, then pocket sprung mattresses rather than materials such as memory foam are a better choice.
