Tips to help you sleep include:

1. Eat kiwis before bed. Researchers at China's Taipei Medical University asked insomniac volunteers to eat two kiwis an hour before bedtime. After four weeks, the volunteers slept faster, better and longer. Kiwifruit is high in folic acid and antioxidants, which may be responsible for the sleep aid.

2. Change your sheets regularly. Bed sheets absorb sweat and body secretion of oil, but also harbor shed skin cells, which are food for dust mites, which can cause allergies and disrupt sleep. A survey conducted by the National Sleep Foundation showed that 71 percent of people sleep more comfortably on clean sheets.

3. Wear amber-colored glasses. Researchers at Columbia University in the United States asked insomnia patients to wear amber-colored glasses 2 hours before bedtime and insisted for a week. The results showed that their average sleep time was extended by 30 minutes.

4, take a warm bath at 9 pm. Taking a warm bath causes blood vessels to dilate and emit heat, which helps regulate body temperature and encourages the brain to generate melatonin, which promotes sleep. Research at Loughborough University in the UK has found that people who take a warm bath at nine o'clock in the evening fall asleep faster and have a longer period of deep sleep compared to those who take a bath earlier.

5, massage the face. A study shows that a 20-minute facial massage before bedtime can lower blood pressure and increase drowsiness.
