Cognitive behavioural therapy
Cognitive behavioral therapy is often suggested as the first line of treatment, which helps to manage stress and remove unpleasant thoughts. It is more effective than medications. The cognitive behavioural therapy may include:
- Stimulus control therapy : This plan helps you get rid of things that stop you from sleeping. For instance, it suggests you go to bed and wake up at the same time every day, skip naps, and if you can’t fall asleep in 20 minutes, leave the bedroom until you feel sleepy again.
- Relaxation techniques : Anxiety can be reduced during bedtime using progressive muscle relaxation, meditation, biofeedback, and breathing exercises. These strategies can help you relax by allowing you to control your breathing, heart rate, muscle tension, and mood.
- Sleep restriction : This therapy reduces the time spent in bed. It also discourages daytime naps, resulting in partial sleep deprivation and increased fatigue the next night. Your time in bed is gradually increased once your sleep has improved.
- Passively awake : This therapy is for learned Insomnia, which is also called paradoxical intention. It aims to reduce worry and anxiety over not being able to fall asleep by staying in bed.
- Light therapy : A light can be set as an internal clock to help you get a good night’s sleep.
Medications for Insomnia
Medications like benzodiazepines and zopiclone are sometimes used to treat insomnia. However, it’s essential to talk to a doctor before taking any medication for insomnia. They can help you figure out which one might work best for you and what possible side effects to watch out for.
