How do I stop over thinking at night?

Try to relax an hour before you go to bed; take a bath, read a good book, drawing. Try to stay away from phones, computers and technology in this hour. Before you go to bed, try to only think about something you're looking forward to on the next day.

Over thinking happenes mostly at night because for most of us it is the only time in the day that we actually stop and are able to think about our past, present and future with no disturbances. Thinking isn't always bad, if it means considering the endless possibilities you have in life and how many great things future holds, but even that can be tiresome if you had a busy day. Try to relax before you go to bed. Have a bath, maybe somecomforting food, listen to calming music, meditate. That way your body will naturally prepare for sleep rather than suddenly trying to 'switch off' and failing.

Do not be an active participant in your thoughts. Disentangle yourself from the incessant monologue/imagery/whatever by observing it. You are not your thoughts. Most (90%~) thoughts are very automatic and happen all by themselves, almost like an autonomous bodily function - like digestion, or your heart beat. It is easy to forget you are not what you think, if you're in your head a lot. You are overly identifying with your thoughts, and so your physioemotional state reflects that. So you must learn to decouple from them. Start by learning to step back from thought and dispassionately observe, and after that you can even learn to silence thought altogether whenever you want. I highly suggest you read up on mindfulness. The entire practice is based on these simple principles, and you'd be amazed at how completely transformative they can be. Even a little bit of mindfulness before bed can lead to a good night's sleep.

By not over thinking during the day.. If you overthink from the time you wake up then this will continue even during the night.

You can always read a book before falling to bed, and you can enjoy a chamomile tea as well. Think about what you're going to do the next day, find something to look forward for tomorrow and persuade your self to sleep well.

focus on what is happening in the moment. it helps if you go through the alphabet and name an animal for each letter. if you finish, go through and do it again. it gives your mind something to focus on until you go to sleep. melatonin is good too (and totally natural)

Try and watch something interesting on tv, or rather talk about a nice topic with your friends. It really helps. You can also try to think about your passion and do something creative, Nights are the best time to do something good about yourselves.

First of all relax close your eyes take deep breath forget about everything have a little me time. Read a book. Listen to your favourite song. Day dream...or talk to a friend

This is a common problem that people experience, and can be fixed by tiring yourself and your brain out more during the day. Doing that is an easy way to make yourself hit the pillow and fall asleep faster.

Try to think about other things besides what you are worrying about. For me, when I am stressed or anxious about something, I think of a fun memory or I make a story in my head. Sometimes just writing it down or talking to someone, even to yourself can help too. Everyone is different, so figure out what works for you.
