To banish stress-related headaches and insomnia, try hand reflexology. Stretch out your right hand and, with your left thumb, apply pressure from the base of your hand and work your way up to the tip of your thumb. Repeat ten times. Alternatively use scent to improve your mood. Drip a few drops of some of the following aromatherapy oils on a handkerchief to sniff when you feel stress levels rising: jasmine, neroli, lavender, camomile, vetiver or clary sage or sip a cup of camomile tea.
