Takeaways

• 😴 Ensure you get 7-8 hours of sleep consistently, as less than six hours is equivalent to being cognitively impaired.
• 🕊 Recognize your chronotype as an early bird or night owl, as it affects the quality of your sleep and should be considered when setting a sleep schedule.
• 🛌 Avoid hitting the snooze button, as it disrupts your body's natural sleep cycle and can lead to increased feelings of tiredness.
• 🏃‍♂️ Engage in physical activity upon waking, as even 30 seconds can improve alertness and reduce the effects of sleep inertia.
• ☀️ Expose yourself to bright light in the morning to stimulate wakefulness and regulate your sleep patterns.
• 💧 Stay hydrated in the morning, as dehydration can affect alertness, concentration, cognitive abilities, and mood.
• ☕ Limit caffeine intake to the morning or midday to avoid impacting sleep quality, as its effects can last for hours.
• 🥗 Focus on a healthy diet, as it can significantly influence your energy levels and sleep quality in the long term.
• 🏋️‍♀️ Incorporate regular exercise into your routine, as it has been shown to improve sleep duration and quality, as well as alertness.
• 💤 Take short naps of 20-30 minutes to boost productivity and cognitive function without entering deep sleep stages.
• 🚫 Avoid alcohol in the evening, as it can disrupt REM sleep and lead to more awakenings during the night.
• 🛁 Have a warm shower or bath before bed to help your body naturally cool down, signaling it's time to sleep.
• 🌙 Sleep in a dark and cool environment to promote better sleep by reducing stimulation and maintaining optimal body temperature.
