Sleep helps your whole body recover and function better. Key benefits include:

• More energy during the day

• Better mood and lower stress

• Sharper memory, focus, and learning

• Stronger immune system — you may get sick less often

• Better heart health and healthier blood pressure

• Better metabolism and weight control

• Lower risk of chronic disease, including type 2 diabetes, heart disease, high blood pressure, and stroke

• Muscle repair and recovery, especially important if you exercise

• Better reaction time and safety, including lower accident risk

The CDC says getting enough sleep can help you stay at a healthy weight, reduce stress, improve mood, improve heart health and metabolism, lower chronic disease risk, and improve attention and memory. NIH also notes that quality sleep supports mental health, physical health, quality of life, safety, and affects how well you think, react, work, learn, and interact with others.
