Sleep is one of the many things we need to stay healthy. It helps us focus, learn, and grow. Not enough sleep can lead to mood swings and getting distracted easily. Tiredness can be caused by a gland in your body that releases a special hormone called melatonin when it's dark. Digital screens can give off blue light which is a small part of light which makes the pineal gland not produce any hormones. Melatonin is what makes you tired, drowsy, and not thinking straight.

Caffeine can also negatively affect your sleep. It gives you energy but doesn't get rid of the melatonin. Caffeine will give your body energy to function but does not get rid melatonin of making you tired. Caffeine is a stimulant which means it increases activity in your brain which makes adrenaline flow faster. Withdrawal from caffeine can lead to headaches, sleepiness, low energy level, and bad moods. Now How much sleep do I need?

Adults need less sleep because, unlike kids, their bodies are not growing and developing. Sleep is important because your brain needs to rest and go over everything that's happened, process memories, fight off diseases, and think clearly. This is why when you're tired it's hard to think. These are the different sleep cycles for different ages. Newborns need 14-17 hours of sleep. Infants 12-15 hours of sleep. Toddlers 11-14 hours. Preschool 10-13 hours. School age 9-11 hours. Teen 8-10 hour. Adults 7-9 hours. Older adults 7-8 hours. These are the different hours of sleep different age groups need to be healthy.
