Still skimping on sleep? You’ll never learn. Literally.

It appears that too little sleep can take a big toll on the part of your brain that’s wired to help you learn from mistakes.

Mind Meltdown
Brain scans of sleep-deprived people performing gambling tasks showed something quite revealing: The orbitofrontal cortex, an area that aids in learning from a loss or a bad decision, was less active. Researchers suspect that poor sleep, besides prompting risky behaviors, hinders the brain’s ability to process emotions, such as regret. The result? You’re less likely to think about the consequences of a decision.

Sleep, Sleep Relief
If being a bad learner isn’t enough, here are some other key reasons to set aside 6 to 8 hours of shuteye tonight:

Sweet Dreams Control Blood Sugar?

Bad sleep habits may set you up for poor blood sugar control.

Sleeping for less than 6 hours or more than 9 hours per night was associated with an increased risk of diabetes in a recent study. These same poor sleep habits also were linked to impaired glucose tolerance, a condition marked by higher-than-normal blood sugar levels. Aim for 6 to 8 hours of sleep per night.

Researchers don’t know exactly why poor sleep habits contribute to overall health risks. Hormones linked to sleep and wake cycles may play a role. A recent study revealed that sleep deprivation reduces levels of leptin, an appetite-suppressing hormone. If you have trouble sleeping, practice good sleep hygiene: go to bed at the same time every night, avoid caffeine or large meals late in the evening, exercise regularly earlier in the day, sleep in a cool, dark room, and unwind before bedtime. Getting the right amount of sleep is only one part of reducing diabetes risk. Exercising regularly, maintaining a healthy weight, and following a healthful diet also can help reduce risk.

Add a good night’s sleep to your checklist of helpful weight-loss aids.

Sleep deprivation interferes with appetite-suppressing hormones, increases stress hormone levels, and decreases a person’s glucose tolerance, all of which may contribute to weight gain. Another way sleep loss may help pile on the pounds: late-night munching. Go to bed and get up at the same time each day to help achieve sounder sleep.

And, It’s good for your heart!
