What is Parkinson’s Disease?7 Early Warning Signs Of Parkinson’s Disease

 How Physical Activity Affects Mental Health?

You already know that exercise is good for your body. But did you know it can also boost your mood, improve your sleep, and help you deal with depression, anxiety, stress, and more?

When you have depression or anxiety, exercise often seems like the last thing you want to do. But once you get motivated, exercise can make a big difference.

Exercise helps prevent and improve a number of health problems, including high blood pressure, diabetes and arthritis. Research on depression, anxiety and exercise shows that the psychological and physical benefits of exercise can also help improve mood and reduce anxiety.

The links between depression, anxiety and exercise aren't entirely clear — but working out and other forms of physical activity can definitely ease symptoms of depression or anxiety and make you feel better. Exercise may also help keep depression and anxiety from coming back once you're feeling better.

Can Physical Activity Improve Mental Health?

Exercise is not just about aerobic capacity and muscle size. Sure, exercise can improve your physical health and your physique, trim your waistline, improve your sex life, and even add years to your life. But that’s not what motivates most people to stay active.

People who exercise regularly tend to do so because it gives them an enormous sense of well-being. They feel more energetic throughout the day, sleep better at night, have sharper memories, and feel more relaxed and positive about themselves and their lives. And it’s also a powerful medicine for many common mental health challenges.

Regular exercise can have a profoundly positive impact on depression, anxiety, and ADHD. It also relieves stress, improves memory, helps you sleep better, and boosts your overall mood. And you don’t have to be a fitness fanatic to reap the benefits. Research indicates that modest amounts of exercise can make a real difference. No matter your age or fitness level, you can learn to use exercise as a powerful tool to deal with mental health problems, improve your energy and outlook, and get more out of life.

Physical activity has a huge potential to enhance our well being. Even a short burst of 10 minutes’ brisk walking increases our mental alertness, energy and positive mood.

Participation in regular physical activity can increase our self-esteem and can reduce stress and anxiety. It also plays a role in preventing the development of mental health problems and in improving the quality of life of people experiencing mental health problems.

how physical activity reduces stress

Exercise increases your overall health and your sense of well-being, which puts more pep in your step every day. But exercise also has some direct stress-busting benefits.

• It pumps up your endorphins. Physical activity may help bump up the production of your brain's feel-good neurotransmitters, called endorphins. Although this function is often referred to as a runner's high, any aerobic activity, such as a rousing game of tennis or a nature hike, can contribute to this same feeling.
• It reduces negative effects of stress. Exercise can provide stress relief for your body while imitating effects of stress, such as the flight or fight response, and helping your body and its systems practice working together through those effects. This can also lead to positive effects in your body—including your cardiovascular, digestive and immune systems—by helping protect your body from harmful effects of stress.

• It's meditation in motion. After a fast-paced game of racquetball, a long walk or run, or several laps in the pool, you may often find that you've forgotten the day's irritations and concentrated only on your body's movements.

  As you begin to regularly shed your daily tensions through movement and physical activity, you may find that this focus on a single task, and the resulting energy and optimism, can help you stay calm, clear and focused in everything you do.

• It improves your mood. Regular exercise can increase self-confidence, improve your mood, help you relax, and lower symptoms of mild depression and anxiety. Exercise can also improve your sleep, which is often disrupted by stress, depression and anxiety. All of these exercise benefits can ease your stress levels and give you a sense of command over your body and your life.

Impact of Physical activity on Mental Health

Physical activity has been shown to have a positive impact on our mood. A study asked people to rate their mood immediately after periods of physical activity (e.g. going for a walk or doing housework), and periods of inactivity (e.g. reading a book or watching television). Researchers found that the participants felt more content, more awake and calmer after being physically active compared to after periods of inactivity. They also found that the effect of physical activity on mood was greatest when mood was initially low.

There are many studies looking at physical activity at different levels of intensity and its impact on people’s mood. Overall, research has found that low-intensity aerobic exercise – for 30–35 minutes, 3–5 days a week, for 10–12 weeks – was best at increasing positive moods (e.g. enthusiasm, alertness).

Impact of Physical activity on stress

When events occur that make us feel threatened or that upset our balance in some way, our body’s defences cut in and create a stress response, which may make us feel a variety of uncomfortable physical symptoms and make us behave differently, and we may also experience emotions more intensely.[18]

The most common physical signs of stress include sleeping problems, sweating, and loss of appetite.[19] Symptoms like these are triggered by a rush of stress hormones in our body – otherwise known as the ‘fight or flight’ response. It is these hormones, adrenaline and nor-adrenaline, which raise our blood pressure, increase our heart rate and increase the rate at which we perspire, preparing our body for an emergency response. They can also reduce blood flow to our skin and can reduce our stomach activity, while cortisol, another stress hormone, releases fat and sugar into the system to boost our energy.[20]

Physical exercise can be very effective in relieving stress. Research on employed adults has found that highly active individuals tend to have lower stress rates compared to individuals who are less active.
