Health and welfare

C'est une question de force :

1. Should est utilisé pour donner un conseil ou une suggestion (ex: You should sleep more $\rightarrow$ C'est une bonne idée).
2. Must est utilisé pour une obligation forte, une règle ou une nécessité médicale (ex: You must take this medicine $\rightarrow$ C'est obligatoire).

💡 À retenir : Should = Conseil / Must = Obligation.

Pour donner un conseil basé sur une condition, on utilise souvent le First Conditional ($If + \text{Present}, \ \text{will/should} + \text{infinitive}$) :

1. Identifie la cause (le problème) : If you smoke...
2. Ajoute la conséquence ou le conseil : ...you will damage your lungs.
3. Ou utilise should pour le conseil direct : If you feel tired, you should rest.

💡 À retenir : Utilise la structure $If + \text{Present} \rightarrow \text{Conseil}$.

1. Infectious disease : A disease caused by bacteria, viruses, or parasites that can spread from one person to another (e.g., the flu, COVID-19).
2. Chronic disease : A long-lasting condition that usually develops slowly and cannot be cured quickly (e.g., diabetes, asthma).

💡 À retenir : Infectious = Contagious / Chronic = Long-term.

You can use verbs and adjectives related to wellness:

1. Use verbs: to eat balanced meals, to exercise regularly, to avoid junk food, to reduce stress.
2. Use adjectives: nutritious, active, fit, healthy. Example: "To maintain a healthy lifestyle, you should eat nutritious food and stay active."

💡 À retenir : Use "balanced diet" and "regular exercise".

Prevention involves several steps:

1. Hygiene : Washing hands regularly.
2. Diet : Eating fruits and vegetables.
3. Lifestyle : Avoiding smoking and excessive alcohol.
4. Medical : Getting regular medical check-ups and vaccinations.

💡 À retenir : Prevention = Hygiene + Diet + Exercise + Check-ups.

Technically, mustn't is stronger than advice; it expresses prohibition.

1. If you want to say something is a bad idea: Use shouldn't.
2. If you want to say something is strictly forbidden or very dangerous: Use mustn't. Example: "You shouldn't eat too much sugar" (Advice) vs "You mustn't drive if you are drunk" (Prohibition).

💡 À retenir : Shouldn't = Conseil négatif / Mustn't = Interdiction.

1. Definition : Mental health refers to our emotional, psychological, and social well-being.
2. Importance : It affects how we think, feel, and act. Good mental health helps us handle stress, relate to others, and make healthy choices.

💡 À retenir : Mental health is as important as physical health.

You can use three main structures:

1. To + infinitive : I exercise to stay fit.
2. In order to + infinitive : I eat vegetables in order to be healthy.
3. So as to + infinitive : He meditates so as to reduce stress.

💡 À retenir : To / In order to / So as to = Pour / Afin de.

1. Cause : The reason why something happens (e.g., Smoking).
2. Consequence : The result of that action (e.g., Lung cancer). Structure: [Cause] $\rightarrow$ leads to $\rightarrow$ [Consequence]. Example: Smoking leads to lung cancer.

💡 À retenir : Cause $\rightarrow$ Result.

Use the Second Conditional ($If + \text{Past Simple}, \ \text{would} + \text{infinitive}$):

1. Use this for things that are not true right now or are unlikely.
2. Example: If I were a doctor, I would help poor people. (But I am not a doctor).
3. Example: If I had more money, I would buy healthy organic food. (But I don't have much money).

💡 À retenir : $If + \text{Past} \rightarrow \text{would}$ (Imaginaire).

A sedentary lifestyle is a way of living that involves very little physical activity. People with this lifestyle spend most of their time sitting (e.g., office workers, gamers) and do not exercise enough. This can lead to health problems like obesity and heart disease.

💡 À retenir : Sedentary = No movement / Sitting too much.

Nutrients are substances found in food that our bodies need to function, grow, and stay healthy. Examples include:

1. Proteins (for muscles).
2. Carbohydrates (for energy).
3. Vitamins and Minerals (for immunity).
4. Fats (for brain and cell function).

💡 À retenir : Nutrients = Essential parts of food.
