Difficulty in falling asleep is usually because of anxiety, tension and stress but can also be influenced by an excessive intake of stimulants, such as caffeine, contained in coffee and colas. Inability to stay asleep can be due to depression, physical pain - such as pain with arthritis  other illnesses like respiratory disorders, or disturbances in normal body rhythms because of jet lag or shift work. Lack of exercise and changes of environment can also play a part. Orthodox treatments often involve sleeping tablets prescribed for short-term use.

Complementary and herbal approaches are

• Psychological therapies - relaxation training, autogenic training (a deep relaxation technique), biofeedback and cognitive therapies have all been shown to reduce insomnia. One of the most effective therapies is sleep restriction whereby the number of hours in bed is limited until a new sleep pattern is created.
• Hypnotherapy - autohypnosis can enable people to fall asleep more easily.
• Dietary change and nutritional therapy - changing dietary habits and food intake can influence sleep. Nutritionists recommend avoiding heavy or spicy meals late at night and cutting down on sugar and caffeine-based drinks. Largish doses of B Vitamins have a beneficial effect on the nervous system and can calm anxiety if taken in food or as a supplement.
• Herbal medicine - the herbs valerian root (Valeriana officinalis) and passionflower (Passiflora incarnata) can reduce insomnia and influence sleep quality. They can be taken as an infusion or as a supplement.
• Acupuncture - may help to restore normal sleep-waking patterns.
• Aromatherapy - essential oil of lavender is a relaxant and oil of bitter orange (neroli) has sedative effect. Both can aid sleep when used externally.
• Massage - can help babies and infant go to sleep and relaxes adults too.
• Light therapy - exposure to bright light in the early part of the day and restricted light exposure towards the end of the day can help to re-establish natural sleep rhythms.
