Can Exercise Help?
Yes! Exercise can be hugely beneficial in helping to prevent and control many of today’s common health conditions.
Diabetes can be a crippling illness, and exercise is the cornerstone of preventing diabetes and managing both Type 1 and Type 2 diabetes. Both strength training and cardiovascular exercise develop muscle fibres that are more responsive to insulin. They work by creating a higher capillary density and greater blood supply. This allows insulin to work much more effectively at regulating blood sugar levels.
Fact: “Being a normal weight and exercising regularly reduces the risk of developing diabetes by 58%”
A lot of evidence suggests that regular exercise can be effective for people suffering from mild to moderate depression and anxiety. It does this by regulating key mood enhancing neurotransmitters (chemical carriers of information throughout the nervous system) improving heart lung function, aiding sleep and enhancing self-esteem. Research shows in some cases exercise can manage depression and prevent relapse as effectively as medication, with none of the undesirable side effects.
Fact: “Over the course of a year 1 in 5 New Zealanders will experience depression or anxiety”
Every day approximately 50 people are diagnosed with cancer in New Zealand. It is estimated that around 80% of these cases are caused by environmental or lifestyle factors and are therefore preventable. Regular activity is one of the keys to reducing the risk of developing some of our most common cancers like breast, colon and prostate cancer. Furthermore, traditional advice to patients undergoing treatment is to “take it easy” has been recently questioned by a comprehensive review of more than 60 studies. It seems that being active during treatment actually has a hugely positive effect on both mood and wellbeing. Once treatment is complete exercise can also reduce the impact of side effects such as swelling, anxiety, depression, fatigue, impaired mobility and changes to weight.
Fact “Exercising to recommended levels (6 hrs per week) can reduce the risk of cancer recurring by 40%”
Coronary Heart Disease (CHD)
(High Cholesterol – High Blood Pressure)
Forty percent of NZ deaths are due to CHD, making it our number 1 killer. The heart responds to exercise by getting stronger and pumping blood more efficiently. Exercise also influences cholesterol by reducing low-density or “lousy” lipoproteins and increasing high-density “happy” lipoproteins, which can help improve blood cholesterol composition (high blood cholesterol can contribute to a narrowing of the arteries which reduces the blood flow and increases the risk of heart attack and stroke). Over the long-term, exercise also lowers blood pressure which, if elevated is a serious contributory factor to CHD and the likely hood of a stroke.
Fact: “Inactivity roughly doubles the risk of CHD and is a major factor for stroke”
It is a misconception that osteoporosis is only relevant for frail, older people and that nothing can be done about it. The medical profession is in agreement that taking steps early on in life will pay dividends in terms of preventing this debilitating condition taking hold later on. Prevention involves having an adequate intake of vitamin D, calcium, and regular weight bearing, high impact exercise. Muscle pulling on bone builds bone, so weight bearing exercise builds denser stronger bones and the more bone mass built before age 25 or 30, the better. Fifty percent of NZ females over 60 already have osteoporosis and about a third of men over 60 have it too.
Fact: “Bone loss in women can begin as young as 25 years of age”
hi guys ..I am a little confused by what was publicized as a safety precaution when shopping in supermarkets. That 1 in and 1 out policy?
The other day I went to get some groceries, first time since the lockdown.
I queued up ..there were only a few of us and I thought to myself, thats good...there was a gazebo outside New World Pioneer Hyway , another plus point... How nice of the shop ...then the woman at the entrance said we could ALL go in ...
To my surprise, there was quite a crowd of shoppers inside already. It was difficult to keep the 2 m distance ..... I was in and out in 30 minutes. If there was a sick person inside, we would all be infected ...
I wish the shop would not let so many people in at the same time ..I would feel safer ...
Or was I being paranoid? what do you think?
