Insomnia makes you hungry
Yes, this one sounds bizarre, but it’s true. It’s due to a hormone called leptin which controls hunger and how full you feel. People who don’t get enough sleep are more likely to have a bigger appetite because it causes their leptin levels to fall.
Exercise isn’t always good for sleeping
It’s got to do with how regularly you exercise, the intensity, and how long you do it before bed time. In short, research seems to indicate that for most people, if you exercise regularly you’ll be a better sleeper. However, if you don’t exercise much but then hit the gym hoping for a decent night’s shuteye, the workout won’t have much of an effect. That’s unless you do it right before bed time, which will probably keep you awake longer.
Short sleepers might be mutants
You’ve heard of famous short sleepers; super productive people who survive on only three or four hours a night. Kevin Rudd, Madonna, Margaret Thatcher and James Franco are some of the more famous ones who need very little sleep. The things you could do with your life with all those extra hours… Scientists don’t agree about short sleepers – some think that they have a mutated gene that means they can operate with less sleep. Others think in reality they aren’t actually operating that well. They believe they’re just chronically sleep deprived, but don’t feel the symptoms.
Women get less sleep
Here’s some facts that might surprise you. In any given week 64% of women are likely to experience insomnia of some description a few nights week compared to only 54% of men. Why is this? The obvious reason that comes to mind is the demands of young kids and babies who need attention through the night. Other reasons include hormonal cycles, and the increased prevalence of sleep –sapping problems among women such as anxiety, stress and depression.
Coffee wrecks your sleep
Researchers have proven what we all know instinctively, that drinking caffeine isn’t good for your sleep. While it may not necessarily stop you from going to sleep, it generally makes your sleep shorter and more disrupted. Like alcohol, it does weird things to the sleep cycles, playing with the normal ratios of rapid eye movement (light sleep) to deep sleep ratios that are crucial to getting proper restorative sleep.
A power nap can lose its power
If you’re going to hit the mattress or couch for a nap, set your alarm so you don’t go past 20 minutes. That’s a proper power nap. Studies have shown that if you go any longer you’ll be going into deep sleep, and awakening from that gives you something called sleep inertia. That’s when you wake up feeling worse than before you dropped off. If you want to wake up feeling refreshed but if you’re lucky enough to have more time on your hands, stretch it out for 90 minutes. That’s when you’re most likely have completed a full cycle, so you won’t wake up groggy and cranky.
