Physical Health Benefits of Sleep

1. Promotes Cellular Repair

• During sleep, your body goes into repair mode, mending tissues, building muscle, and strengthening the immune system.

2. Supports a Healthy Heart

• Sleep helps regulate blood pressure and reduces inflammation, both of which are vital for cardiovascular health.

• Poor sleep has been linked to an increased risk of heart disease and stroke.

3. Enhances Immune Function

• During deep sleep, your immune system produces infection-fighting substances like cytokines.

• Chronic sleep deprivation weakens your immune response, making you more susceptible to illnesses.
