Your sleeping habits can directly affect your wellness. 

When it comes to your immune system health, sleep is one of the drivers of your immune cells (1, 2). When sleeping, your body’s melatonin levels rise and growth peptides are released. These put your immune cells to work. Good sleep leads to supported immune cells. 

4 ways to improve your snooze 

  1. Same time, every day
    Don’t give in to the temptation to stay up or sleep in super late. The more consistent you are, the better.
  1. Reduce blue light
    Set a screen time cut-off. Research shows exposure to blue light suppresses the production of melatonin more than any other type of light.
  1. Me time at night time
    Wind down with a hot bath or a good book. Calming your body and mind helps prepare your body.
  1. Sounds about right
    Turn on a nighttime meditation or some white noise via an app on your phone. Your mind will be less likely to wander.

Remember, good sleep leads to supported immune cell health. Wishing you peaceful dreams and healthful days.
