If you’ve been following this blog, you’ll know that there’s a mind-blowing amount of things that can affect one’s sleep. It’s fascinating learning more about them as sometimes they can be quite unexpected but once you get to know the reason behind them, it makes perfect sense.
Another addition to this list is an optimistic disposition in life. According to a study done for the Coronary Artery Risk and Development in Young Adults (CARDIA), there are significant associations towards better quality sleep and one’s sunny disposition.
It turns out, that those who are optimistic tend to sleep more, with better quality and longer duration than their broody peers. If you’ll think about it, though, it makes sense as the amount of sleep you get also affects your mood. If you get enough sleep, you’re more energetic, upbeat, and in an all-around better mood. If you’re sleep-deprived, you’re grumpier and will most likely rely on caffeine to keep you awake and energized the whole day. Unfortunately, too much caffeine can also be the very reason why you can’t sleep well at night, creating a vicious cycle of sleeplessness and grumpiness.
But what really comes first, your good mood or your good sleep? The study mentioned above looked into that with the help of 3500 subjects aged 32-51 over a period of 5 years. Their disposition was measured through a 10-question survey and had their sleep monitored through regular reporting. Some subjects took things up a notch by having their sleep scientifically monitored.
Results show that those who are more optimistic than others are more likely to have better sleep than the ones that are less optimistic. They’re also less likely to become insomniacs or experience daytime fatigue.
While researchers haven’t really found out why and how optimism affects one’s sleep, there’s still some evidence that one’s positive disposition also has a positive impact on their rest. There may still be a need to study this further but it’s already a good start that might convince people to take a more positive change in their lives to get better zzz’s.Tags:
