The mechanism behind sleep and immunity

Here it is, although your body’s immune system works through the day as well; however, the night time comes as an opportunity for your immune system to work without interruptions or obstructions. These interruptions include having food, doing exercise, or other movements.

The importance of sleep can be understood in this way that your body’s immune system demands a lot of energy for its proper functioning. Now, when you sleep at night with all these activities being null, it utilizes as much energy as it wants and functions faster.

The specialized immune cells of the body, known as T-cells, respond to any harmful foreign material that enters the body. T-cells activate integrin and attach and handle the target.

In a study, it was found that T-cell shows higher levels of integrin activation during sleep. This is mainly because stress hormones dip while one is sleeping, which is known to reduce T-cells’ efficiency.
