In recent years, sleep deprivation has become a major public health concern. Moreover, it seems like a growing number of people I talk to are not getting the sleep they desire. Worries about bills, the economy, work, and more have them awake at night. Yet they are not alone.
It’s estimated that roughly 30 percent of adults in the U.S. aren’t getting enough sleep for good health, and up to 70 million may have a sleeping disorder. Poor sleep can increase the risk of a cardiovascular event, weight gain, and several other health conditions.
The study, published in the journal Behavioral Medicine, found that optimists are less likely than pessimists to suffer from insomnia. They also enjoy longer, better quality sleep. The finding builds on a study noting that optimists also enjoy better heart health.
Examining 3,548 participants and using surveys to indicate outlook and sleep quality, researchers found that optimists are 74 percent less likely to experience insomnia than pessimists and more likely to get the recommended amount six-to-eight hours of uninterrupted sleep per night. Their chance of getting good quality sleep was 78 percent better than pessimists.
There are several tools you can use to improve sleep. Getting exercise (which can also help with stress relief and anxiety), sleep hygiene, and limiting alcohol in the evening can all have a positive impact and are slightly more accessible than an outlook overhaul. That said, according to a specialist writing for Psychology Today, it is possible to change your overall outlook. It does, however, take some time. They suggest:
- Identifying your negativity, so you’re conscious of when you’re being negative.
- Try to see the positive side—it may feel fake at first, but in time, it may become reflexive.
- Write down your negative thoughts and the evidence you have to support them. Then, in another column, write evidence that argues that point. It can help you identify both good and bad, and perhaps begin to improve overall outlook by considering multiple sides/scenarios.
