Sleep: How much and why?

The optimal amount of sleep can vary based on age, individual needs, and lifestyle factors. The American Academy of Sleep Medicine and the Sleep Research suggest that adults (18 – 60 years) should aim for between 7-9 hours per day.

Why sleep is important?

• Cognitive Function: Adequate sleep is crucial for optimal cognitive function, including memory consolidation, problem-solving, and overall mental clarity.
• Emotional Well-being: Sleep plays a key role in regulating emotions and mood. Insufficient sleep is linked to increased irritability, stress, and a higher risk of mood disorders.
• Physical Health: Quality sleep is associated with a lower risk of chronic conditions such as obesity, diabetes, cardiovascular diseases, and a bolstered immune system.
• Recovery and Repair: Sleep is a time when the body undergoes essential repair and rejuvenation processes. This includes muscle growth, tissue repair, and the release of growth hormones.
• Performance and Productivity: Whether in academics, work, or daily tasks, well-rested individuals tend to be more alert, focused, and productive.
• Regulation of Appetite: Sleep influences hormones that regulate appetite, potentially affecting weight management.
• Immune Function: Quality sleep supports the immune system, helping the body fend off infections and illnesses.
• Overall Well-being: Consistent, restful sleep contributes to an improved overall sense of well-being, increased energy levels, and a better quality of life.
