Insufficient sleep can be caused by factors such as fatigue, drowsiness, moodiness, loss of energy, and lack of concentration. Ways to help establish and maintain a sleep routine are:
- Avoid caffeine and nicotine three to four hours before going to bed.
- Go to bed and wake up at the same time every day.
- Aim to get seven to eight hours of sleep per night.
Create a good sleep environment, including a comfortable room temperature, minimal noise, and sufficient darkness.
