How do I stop over thinking at night?

This is not an easy thing to do, but that doesn't mean that it is impossible or beyond your reach. You certainly need to make changes in your life if you really want to stop over thinking at night, particularly when you're laying down on bed trying to sleep. As a lifetime over-thinker at night I've found out that mindfulness meditation helps a lot, so does exercise and avoidance of screens - phone is the worse, then computer/laptop and finally tv, because of the size of it - afer dinner (or 2-4 hours before bed).

Overthinking at night when trying to fall asleep is something I've struggled with a lot, too - and still do sometimes. What usually helps me is to have a piece of paper and a pen next to my bed. Just before going to bed I'll try writing down the things that are worrying me and circling around in my head. This usually helps clear my brain. Also, whenever I and start overthinking I'll make the conscious decision to think about something - anything - else. Maybe I'll recall a good thing that happened that day or week in as much detail as possible. Or I'll daydream about some nice situation I can imagine myself being in. Anything, really, to force my thoughts to focus on something else.

Thinking about positive things and that tomorrow is a new day with a new energy

What helps me is is a nice hot shower followed by calming music. When your out and about its always a good idea to head to your comfort zone where you feel safe

I usually count sheep to get my mind off things. If something is bothering you try writing it down then worry about it then next day.

You've got to find that one thing that relaxes you. It'll be different from person to person. It could be breathing deeply, listening to soft music, imagining pleasant and positive scenarios in your head...whatever works for you. In my case, I found that listening to audiobooks at bedtime is all I need. It's nice focusing on someone else's voice instead of our own frantic thoughts at night.

Nightly rituals before bed are helpful to put our mind in a place of peace - for good rest. Yoga, listening to music, reading a prayer or devotional, etc. The important part is, to tell yourself as you begin this ritual that it is time to shut off your thoughts and just enjoy your current activity. Remind yourself this special time is just for YOU, and that the time for problem solving will resume in the morning.

My mind often races at night as well. A lot in fact. But I can note that the more physically active I was that day can make a difference. On days where I know I didn't exert myself as much I can also achieve the same peaceful sleep results by doing a brief work out in my room before hoping into bed. Does not need to be anything over the top. You just need to exhaust yourself. Me personally, I stick with squats, push ups, and donkey kicks. After that I drink some ice cold water, go to the restroom one last time, and fall peacefully into bed.

Try meditation, it helps the mind and body to relax and overcome a lot of thinhs and the overthinking is one of them.

One things that has helped me to stop overthinking at night is to listen to relaxing music. It helps me to relax, and is a good distraction from overthinking.
