Talking too much
After working the whole day and the fact that many spouses get a little time to discuss issues, many couples discuss significant problems in the bedroom. Communication is necessary, but should be done at the right time. Talking about sensitive issues late in the night may affect your sleep adversely. Sometimes, depending on what you are talking about, you could end up sleeping late and therefore not getting enough of sleep.
Conclusion
Take time to identify the main things that affect your sleep. Find a way to control this so that you get the quality sleep that you deserve.
