Hello ,my name is dr.Dorina Gurabardhi.Isomnia is the inability to get the amount of sleep you need to wake up feeling rested and refreshed. Sometimes, insomnia only lasts a few days and goes away on its own, especially when the insomnia is tied to an obvious temporary cause, such as stress.Causes of insomnia in your case can be psychological problems and emotional distress.So you should: -Develop a better bedtime routine -Stick to a regular sleep schedule. -Avoid naps -Limit caffeine, alcohol, and nicotine -Avoid late meals -Get regular exercise -Avoid stimulating activity and stressful situations before bedtime. -Turn off screens one hour before bedtime. I hope this was helpful.
