The hormone cortisol has many functions; one of which helps fight off infection and sickness.
More cortisol circulates in our blood during the day, which suppresses our immune system. This means that your white blood cells, which are responsible for fighting infections, are less active during the day.
At night, there is less cortisol in your blood, so your white blood cells detect and fight infections in your body at this time, causing the symptoms of the infection to increase making us feel sicker at night.
Make sure to sleep well and drink water to strengthen your immune system for faster recovery!π¦π΄
