That's right. Sleeping apart can help.
Consider having a sleeping in solitude holiday. It doesn't even need to be fancy. When I work nights I sleep in a tent in my basement but I can guarantee it's gotten me the sleep I need to continue on.
Some studies show that sleeping together can cause worse sleep in the end. This can be exacerbated when you have children or your partner snores. Sometimes, couples have different sleep-wake cycles so you can cause habitual sleep deprivation.
We all need a break. Free from stress of wondering if our partner will take all the blankets or wake us up by tossing and turning. Consider sleeping alone.
