Adequate sleep is crucial for maintaining physical and mental health. Studies have shown that getting 7-9 hours of sleep per night can improve mood, cognitive function, and immune system function. But quality of sleep is also important. A study published in the Journal of Sleep Research found that slow-wave sleep (deep sleep) is important for memory consolidation and learning. The hormone melatonin plays a key role in regulating our sleep-wake cycle. Exposure to natural light during the day and avoiding screens before bed can help regulate melatonin levels and improve sleep.

What should you avoid for a better sleep?
Consuming heavy meals, or too much fat, protein, or sugar close to bedtime can disrupt sleep for several reasons:
-
Digestion: Heavy meals close to bedtime can make it difficult for the body to properly digest food. This can lead to discomfort, indigestion, and acid reflux, which can disrupt sleep.
-
Blood sugar: Consuming too much sugar or carbohydrates close to bedtime can cause blood sugar levels to spike, leading to energy and alertness, making it hard to fall asleep.
-
Stimulation: Consuming too much protein or fat close to bedtime can stimulate the body and brain, making it difficult to relax and fall asleep.
-
Hormones: Eating a high-fat or high-carb meal close to bedtime can lead to an increase in insulin, which can disrupt the balance of hormones that regulate sleep-wake cycles.
-
Insomnia: Consuming too much sugar, caffeine, or alcohol close to bedtime can cause insomnia, making it difficult to fall asleep and stay asleep.
Overall, it's best to stick with a light, balanced snack that provides a balance of nutrients, such as a small serving of carbohydrates and a small serving of protein, that can help the body to relax and fall asleep.
