Acupuncture involves inserting very fine needles in to different parts of your body (called acupuncture points). This is believed to stimulate nerves and muscles which may release natural pain-relieving chemicals.
It's based on the belief that health problems can be caused when energy (or your 'Qi') becomes 'blocked'. Acupuncture aims to unlock your energy channels to restore the flow of your Qi.
Acupuncture is mainly used for headaches or chronic pain, but some people feel it helps to relieve symptoms of depression and anxiety.
Aromatherapy uses essential oils (oils extracted from plants) for healing. Some people find that the smell (aroma) of particular oils helps them to relax, sleep better, relieve pain and improve low mood. For example, when used appropriately lavender and camomile essential oils are thought to be relaxing and help you sleep.
The oils can be used in many different ways, such as in creams, oil burners, massaged in to the skin or by adding drops to a warm bath.
It is possible to experience allergies or reactions to the oils, so you should speak to an aromatherapist beforehand if you have any concerns.
This is based on ancient Indian theory and uses medicines made from plants and minerals to restore balance in the body. Ayurvedic medicine also includes massage and panchakarma (therapies that aim to get rid of the toxins in the body using massage and herbal oils).
The Bowen technique (named after Thomas Bowen who developed the therapy) is a kind of contact therapy, meaning the practitioner does touch you, but it is a very light touch which can be done through light clothing. They use very gentle rolling motions with pauses in between.

Homeopathy involves using extremely diluted (watered down) natural substances to treat physical and mental health problems. Homeopaths believe that the more a substance is diluted, the more effective it will be – and the less likely it will be to cause any unwanted side effects.
Some people find that trying homeopathic remedies for stress, anxiety and depression does make them feel better.
However, most doctors are sceptical about homeopathy. The NHS says that the evidence shows homeopathy works no better than a placebo (a sugar pill). It also cautions that choosing homeopathy as your main treatment may mean you don't choose other options, which could work better.
There are various different schools of mediation, but all aim to quieten your mind and put you into a state of calm, stillness and rest. Some types of meditation may also involve mindfulness.
While the evidence is mixed as to whether meditation is effective at treating mental health problems, many people do find it a helpful way of relaxing and managing feelings of stress and anxiety.
There are many DVDs, apps, and free online videos that can teach you meditation exercises.
Mindfulness involves focusing your attention to what's happening in the present moment. It aims to help you become more aware of your thoughts and feelings, so you can choose how to react to them calmly.
Many people find mindfulness helpful for managing negative thoughts and feelings of stress.
Mindfulness helps me manage when my brain decides that a dozen ideas at once is the best way to work. It's not a ‘cure all’ for me, and I have to work at it, but it is a key part of my coping strategy now.
Reflexology is based on the idea that different points on your feet, hands, face and ears are linked to other parts of your body through your nervous system. During a typical session, a reflexologist will use their hands to apply gentle pressure to these points.
Reflexologists recommend this treatment as a way to relieve tension, improve mood and help you to sleep.
Reiki is a Japanese technique which involves the 'laying of hands' on different areas of the body including the head, shoulders, stomach and feet. It's based on the idea that we have a 'life force energy' that flows within our bodies. When this energy is low, it makes us more likely to become unwell.
A Reiki treatment aims to restore life force energy to help you to heal and stay well. Some people find it makes them feel more relaxed and less stressed.
