• The minimum to gain health benefits the Department of health recommends
• 30 minutes of moderate exercise 5 days a week.
• This does not need to be achieved in a single bout can be split up
• Moderate activity- you become warmer and a little out of breath
Physical Activity
• Consider what exercise could you do which meets the Department of Health guidelines
• Using the I-pad click onto the Fitness Pro application and identify 2 resistance exercises for each body part that you could perform and 1 cardiovascular exercise
Activity
• Most widely used drug in the world
• MODERATE consumption may improve health– Reduction in heart attacks– Reduction in strokes
• 16-24 heaviest drinkers!
• 1 unit = 8g of alcohol ( 10ml of pure alcohol)
• 1 gram = 7 calories
• Each unit contains 56 ‘empty’ calories
Alcohol- facts
– Hypertension- above 140/90– Depression – Heart disease– Stroke– Cancers of liver, breast, mouth,
throat– Damage to liver- cirrhosis– Mood swings
– Liver gets rid of poison in blood, helps immune system fight infection, protein that clots blood and produce bile (breaks down fats) - damages liver & makes scar tissue which replaces normal tissue. 26000 deaths/year
Alcohol- associated risks
• Binge drinking is bad because:
– Surge in blood pressure
– Stroke in an otherwise healthy person
– Heart attacks and
– Increase in the possibility of accidental injury
– Lose balance, beer goggles, alcohol poisoning – vomit, Death by drowning
• Stroke:
– Blood is prevented from getting to the brain which results in dizziness headaches and a loss of coordination.
– Effects may be mild lasting for a few minutes of may cause death.
Effects of alcohol
Binge Drinking
What are your limits?
• (For those aged 18+!!) How much alcohol do you think you should be drinking?
• How many units should you consume per day?
Recommended limits• 3-4 units per day for
men• 2-3 units per day for
women
• 1 unit =– ½ pint beer, lager or cider– Small (125ml) glass of
wine– 25ml spirits– This is assuming the beer – is 3.5% abv wine=9% – and spirits = 40%
• 10% of all RTA involve excess alcohol
• 25% of school exclusions are thought to be alcohol related
• Alcohol related absenteeism costs British industry around £2billion per year.
• Using the I-pad click onto the NHS Drinks Tracker application
• And write the answer the following question:
• What is the legal blood alcohol limit when driving?
• Using the information from the theory and the application, now work out how many calories are in 1 pint?
(How many units are in 1 pint, how many calories are in 1 unit?)
Activity
What is in your cigarette?
• 12million adults smoke in the UK (approx)
• 114,000 smokers die every year because of their habit
• 30 % of all cancers related to smoking
• 4000 chemicals in tobacco smoke– Nicotine
– Tar
– Carbon monoxide
Smoking- facts
Smoking – lung damage
• Nicotine – addictive, stimulates the CNS and increase heart rate and blood pressure, can be extremely poisonous in large amounts
• Tar – brown and treacly in appearance. Left in the lungs and respiratory system includes things like cyanide, arsenic and benzene
• Carbon Monoxide – binds to haemoglobin and prevents the blood carrying oxygen around the body
Smoking- what happens
The Health Risks of Smoking
o Coronary Heart disease– atherosclerosis (narrows blood vessels)
o Blood clot could cause heart attack or stroke, kidneys, legs – gangrene/amp
o Cancer (bladder, oesophagus, kidneys, pancreas, cervical cancer)
o Emphysema – alveoli damage
o Bronchitis – cough from mucus production
Activity
• Using the I-pad click onto the NHS Smoke free application

Stress
• What makes you stressed?
• How do you feel when you are stressed?

Stress
• Stress can be a physiological and psychological response to triggers in the environment

• Stressors are factors that initiate a stress response
– Fight or flight – adrenaline
• Constant stress raises adrenaline level/cholesterol levels –can lead to CHD/ weight gain/
• Chronic stress exposes your body to elevated levels of stress hormones like adrenaline and cortisol.
• Health risks associated with stress:
– Hypertension
– Heart attack
– Angina
– Stroke
– Ulcers
– Exhaustion
– Illness- immune system suppressed
– Depression
– Colitis
