Sleep is essential for good health and well-being. It is the time when our body repairs and rejuvenates itself, but lack of sleep can put us at risk of various illnesses including flu, colds and pneumonia.

In this article, we will discuss the connection between sleep deprivation and respiratory illnesses and find out if you are at risk of getting sick due to lack of sleep.

How does sleep affect our immune system?

Our immune system is responsible for defending our body against viruses, bacteria and other harmful pathogens. When we sleep, our body produces cytokines, which are proteins that help the immune system fight infections, inflammation and stress.

Lack of sleep can reduce the production of cytokines, making us more susceptible to illnesses.

The link between lack of sleep and respiratory illnesses

Inadequate sleep has been linked to an increased risk of respiratory illnesses such as colds, flu and pneumonia.

According to a study published in the journal Sleep, people who sleep less than six hours a night are four times more likely to catch a cold than those who sleep seven hours or more. Lack of sleep also weakens the immune system, making it harder for our body to fight infections.

Who is at risk of getting sick due to lack of sleep?

Everyone is potentially at risk of getting sick due to lack of sleep, but some groups are more vulnerable than others. Here are some factors that increase your risk:.

Shift workers who work irregular hours and have disrupted sleep patterns
People who travel frequently and experience jet lag
Individuals with sleep disorders such as insomnia or sleep apnea
