Improve the quality of your sleep
It may not be obvious at first sight, sleep plays a huge role in keeping our body healthy. Getting enough sleep is crucial to improve immunity because it allows the body to produce enough cytokines — the type of protein that aims especially at fighting against inflammation and minor infections.
Humans need on average around 8 hours of sleep every night, and it is highly advised by the Sleep Foundation to do so. If you can’t allow yourself to sleep 8 hours for whatever reasons, try to make it up with naps. Investigations have shown that taking two naps a day, that is not longer than 30 minutes, significantly decrease the negative impact of sleep deprivation on the immune system, as well as it reduces overall stress level.
