1. Why Is Sleep So Important?

Before we discuss the ideal sleep duration, let’s understand why sleep is essential for your health.

1.1. Supports Brain Function

🧠 Sleep helps improve memory, concentration, and decision-making skills. When you sleep, your brain processes information, making learning easier.

1.2. Boosts Physical Health

💪 During deep sleep, your body repairs tissues, builds muscles, and strengthens the immune system. Poor sleep increases the risk of heart disease, diabetes, and obesity.

1.3. Regulates Mood and Mental Health

😌 A lack of sleep can cause irritability, stress, and anxiety. Proper rest helps stabilize emotions and reduces the risk of depression.

1.4. Helps with Metabolism and Weight Control

🍽️ Sleep affects hormones that regulate hunger. Not getting enough sleep can lead to overeating and weight gain.

🚀 Tip: Sleep is just as important as diet and exercise for maintaining a healthy lifestyle.

2. How Many Hours of Sleep Do You Need?

The amount of sleep you need depends on your age. Here’s a breakdown of the recommended sleep duration for different age groups:

Age Group	Recommended Sleep Duration
Newborns (0–3 months)	14–17 hours
Infants (4–11 months)	12–15 hours
Toddlers (1–2 years)	11–14 hours
Preschoolers (3–5 years)	10–13 hours
