There are a lot of decisions married couples need to make when it comes to sleep. Most of these will not come up if you’re single and you’re just doing your own thing. But as soon as you add another person into the mix, there’s all sorts of stuff that needs to be figured out!
Do you both go to sleep at the same time? Do you wake up at the same time? And more importantly does it matter to either of you? Advantages of going to bed at the same time can allow for couples to talk before falling asleep and waking up at the same time can help with getting the day started and having breakfast together. Going to bed at different times can help if one person snores and the other can fall asleep first and waking up at different times can be helpful if you share a small bathroom. It’s completely personal and there isn’t one solution that would work for all couples and I don’t think one way is better than the other.
Do you even share the same bed? I have read about married couples who sleep in different beds in different rooms and my thought is that you need to do what you need to do to get good sleep. If one person snores or moves around a lot at night, maybe the only solution for both people to get enough sleep is to sleep in separate beds or separate rooms. Maybe one person needs a little light in the room and the other needs complete darkness to fall asleep, if neither person can change – it’s better to agree to have separate rooms than have one person never sleep well.
Does your spouse steal the blankets at night? Perhaps get separate blankets. Does your spouse need the room to be cold at night? Perhaps wear warmer pajamas or add a blanket. Does your spouse need the room to be warm at night? Maybe you can agree on a doable temperature that can work for both of you.
Work it out. Figure it out and find a solution that works for you and your spouse even if it might seem odd to other people.
