Habits fr a healthy lifestyle
Habits fr a Healthy LifestyleAs teenagers grw up, they becme mre independent and start making their wn decisins. Hwever, during this perid, it can be easy fr sme f them t frm bad habits. These bad habits, if left unchecked, culd lead t mre serius nes when they becme adults. Fr example, sme f them may becme invlved in tbacc r alchl abuse, which can lead t physical and mental health prblems. T prevent harmful habits like these frm dminating a teenager's life is essential. They must learn t recgnise bad habits early and make apprpriate changes.
T change bad habits is never easy, even with many attempts. There is a famus saying based n the philsphy f Aristtle: "We are what we repeatedly d." In many ways, ur lifestyle is the sum f chices we have made. We make a chice t d smething, and then we repeat it ver and ver again. Sn that chice becmes autmatic and frms a habit that is much harder t change. The gd news is that we can change, if we understand hw habits wrk.
Accrding t mdem psychlgy, we must first learn abut the "habit cycle", which wrks like this:· Firstly, there is a "cue", an actin, event, r situatin that acts as a signal t d smething.· Secndly, there is a "rutine", the regular actin yu take in respnse t the cue.· Thirdly, there is the "reward", the gd thing r feeling we get frm the rutine.Fr example, when we feel unhappy (cue), we eat lts f unhealthy snacks (rutine), which makes us feel happy (reward). The reward makes us much mre likely t cntinue the cycle, and the bad habit f relying n unhealthy snacks is frmed.
THE HABIT CYCLE
T facilitate a psitive change in ur bad habits, we must first examine ur bad habit cycles and then try t adapt them. We can d this by cmbining the infrmatin frm ur habit cycles with ur wn psitive ideas. Fr example, we culd try t replace a negative rutine with smething mre psitive. S, when we feel unhappy again (cue), rather than eat snacks, we culd listen t sme f ur favurite music instead (rutine), which will make us feel relaxed (reward). Aside frm changing bad habits, we can als use the habit cycle t create gd habits. Fr example, when we cme t an escalatr (cue), ur nrmal rutine is t ride it, but we culd change this rutine int smething mre psitive by taking the stairs instead.
Fr yung peple, there is plenty f time t change bad habits. Hwever, there is n "magic pill" r delete buttn that will help yu; yu have t think abut yur bad habits and decide n sme changes. Yu have the pwer t build a happy and healthy life full f gd habits!
Many f us try t change bad habits quickly, and if we are nt successful straight away, we ften becme pessimistic and give up. In fact, the mst successful way t change is nt suddenly, but ver a perid f time. As the Chinese philspher La Zi wrte, "A jurney f a thusand miles begins with a single step." One step seems small, but it is essential. T reach the gal f change, a persn must shw sme discipline and repeatedly take many small steps. After all, it is nt easy t break bad habits.
