There is a lot you can change within your own life that will help your mind to stay sharp. How you look after your physical health will affect your mind so changing things such as your diet, exercise, sleep and choices will all help to keep you well and reduce your risk of mental ill-health. Have a read and see what changes you could make. 

Mental health influences our physical health

Physical health influences our mental health




Mental health influences our physical health

Our body and mind are linked so how healthy you are physically has a direct influence on how healthy you are mentally.


One of the big players in this relationship is stress. If you are very stressed on a regular basis you can develop the symptom effects of ‘allostatic load’. This means that because of your constant stress, your body’s systems (organs, tissues, hormones such as cortisol and epinephrine) involved in the stress response become damaged over time, which can lead to disease over longer time periods (McEwan, 1998).

This weakens our immune systems so we’re more likely to suffer more often from coughs and colds and sometimes more serious complaints.  Also if you’re stressed you’re more likely to have problems with sleep, are more likely to use alcohol and drugs, have a poor diet, and not exercise, which all reduce your mental and physical health further (Kiecolt-Glaser & Glaser 1988). This is why managing stress in our lives is so important.

Mental health problems

If you have a more serious mental health problem you may be at a greater risk of physical health problems. Research has linked depressive symptoms with some of the most common serious health problems in the UK, including: heart disease; cancer risk; risk of osteoporosis (weak bones) in women; and general ill-health from increasing pain and disability (Kiecolt-Glaser et al, 2002). 

Anxiety has also been linked to the development of heart disease and risk of heart attacks in some groups of people (Kiecolt-Glaser et al).

Mental health medications

SASBThe side effects of certain medications used to treat mental illness (such as antipsychotics or antidepressants) can also have an impact on our physical health. Medications can sometimes have side-effects such as movement disorders, reduced sexual function or weight gain. It is important to be aware of any changes in your physical health if you have a mental health problem or take medication. There is much you can do to look after your physical health which will enhance your mental health; and vice versa.

Physical health influences our mental health

Of course this relationship works both ways and our physical health can affect our mental state and how we feel and think about things too.

Being physically unwell

Having a physical illness can get in the way of work or school, your relationships with other people and your social life. Being unwell or having treatment can be stressful which can leave us more prone to anxiety and depression. Being unwell can make us feel angry and frustrated, worried about our health, our future and sad that we can’t do things we would usually do. If you have a serious or long-term illness these emotions can be even more intense and you may feel isolated or that you are losing your control of your life. These situations can have a big impact on your emotional wellbeing and mental health.


Exercise is a great way to improve your physical and mental health and really does help some mental health problems.

Why should I bother?

  • Exercise helps to reduce our stress levels and their damaging effects on the body
  • Exercise can give you a sense of power over your own recovery, which at the same time may lessen any feelings of hopelessness often experienced in problems like depression.
  • Exercise helps use up the adrenaline released in the "fight or flight" response by our autonomic nervous system and relaxes the muscles, while strengthening the heart and improving blood circulation.
  • Exercise can help raise your self-esteem, reduce sleep problems, improve memory and concentration, take your mind off negative thoughts as well as reduce feelings of anxiety and depression.
  • Exercise is a recommended treatment for depression and has been shown to be as effective in treating depression as medication or psychotherapy.

  • Exercise is a sustainable behaviour change. Once you’ve learnt it you can fit it into an overall healthy lifestyle.
  • Exercise has a number of coincidental benefits, including reduced risk of heart disease, stroke, high blood pressure, some cancers, type 2 diabetes, osteoporosis and obesity (Mental Health Foundation, 2005).
  • Exercise is a popular treatment– in one survey, 85 % of people with mental health problems who used exercise as a treatment said they found it helpful (Mental Health Foundation, 2005).
  • Doing exercise has been associated with reduced anxiety, decreased depression, enhanced mood, improved self-worth and body image, as well as increasing positive thinking (Mental Health Foundation, 2005).

We all know that eating healthily can ward off physical illnesses such as obesity, strokes, heart-attacks and type 2 diabetes but did you know that the same is true for our mental health? When things get too hectic and you feel stressed it's easy to forget about what you eat. However, what we eat, and when, can make a big difference.
