6. Negative Lifestyle Factors
Transcript of 6. Negative Lifestyle Factors
What are they?
Healthy weight, diet and exercise
Alcohol interferes with the brain’s communication pathways, and can affect the way the brain looks and works. These disruptions can change mood and behavior, and make it harder to think clearly and move with coordination.
Drinking a lot over a long time or too much on a single occasion can damage the heart, causing problems including:
Cardiomyopathy – Stretching and drooping of heart muscle
Arrhythmias – Irregular heart beat
High blood pressure
Research also shows that drinking moderate amounts of alcohol may protect healthy adults from developing coronary heart disease.
Heavy drinking takes a toll on the liver, and can lead to a variety of problems and liver inflammations including:
Steatosis, or fatty liver
Alcohol causes the pancreas to produce toxic substances that can eventually lead to pancreatitis, a dangerous inflammation and swelling of the blood vessels in the pancreas that prevents proper digestion.
Drinking too much alcohol can increase your risk of developing certain cancers, including cancers of the:
Drinking too much can weaken your immune system, making your body a much easier target for disease. Chronic drinkers are more liable to contract diseases like pneumonia and tuberculosis than people who do not drink too much. Drinking a lot on a single occasion slows your body’s ability to ward off infections – even up to 24 hours after getting drunk.
: Nicotine disrupts normal neurotransmitter activity, causing chemical changes and addiction. Other neurological symptoms caused by nicotine include light-headedness, sleep disturbance, dizziness, and tremors.
Heart and Arteries
: Nicotine increases heart rate and raises blood pressure when it stimulates the release of adrenaline. Short term, this means your body is less efficient when you exercise. It has to work harder getting the blood and oxygen to cells that need it, preventing the body from reaching its maximum potential. Long term, the stress on the heart and arteries can lead to increased risk of heart attack and can even lead to a stroke and/or aneurysm.
: Nicotine reduces the ability to see at night by stopping the production of pigments in the eyes specially designed for low-light vision. Adrenaline released by nicotine reduces peripheral vision, and in the end, nicotine accelerates the degeneration of the eyes.
: Nicotine increases calories burned but decreases endurance by wasting energy in the effort.
: Nicotine prohibits proper blood circulation and is a leading cause of erectile dysfunction (impotence) for men under 40. Nicotine also increases the risk of infertility and miscarriage. And if babies exposed to nicotine in utero do make it to birth, they tend to have low birth weights, be born prematurely, and have increased risk for lung problems.
: When used over time, nicotine alters cellular structures and has been found to increase risk for fractures while contributing long-term to the development of weakened bones (osteoporosis).
One in three of us suffers from poor sleep, with stress, computers and taking work home often blamed.
Most of us need around eight hours of good-quality sleep a night to function properly – but some need more and some less.
Everyone’s experienced the fatigue, short temper and lack of focus that often follow a poor night’s sleep.
An occasional night without sleep makes you feel tired and irritable the next day, but it won’t harm your health.
After several sleepless nights, the mental effects become more serious. Your brain will fog, making it difficult to concentrate and make decisions. You’ll start to feel down, and may fall asleep during the day. Your risk of injury and accidents at home, work and on the road also increases.
What does sleep do?

Sleep can slim you
Sleep boosts mental wellbeing

If you don't know why these are important then I have not done my job!!!
In pairs, give reasons why the following could have a negative impact your lifestyle:
How does alcohol affect the body?
How does smoking effect the body?
What does sleep do for the body?
Using the information you have found create a poster explaining the negative lifestyle factor and what effects it has on the body.
You should try to include as much detail as possible, such as:
Government guidelines/Recommended levels (if any)
Effects on the body
Problems that can occur
The impact on sports performance
Benefits of sticking to guidelines
Strategies that can be employed to help reduce usage (drugs, alcohol, tobacco) or increase opportunities (sleep, exercise etc)
