Emma made a table showing habits that are good and those that are bad for the nervous system. Habits that are good for the nervous system: exercising regularly, using tranquilizers or stimulants, getting plenty of rest. Habits that are bad for the nervous system: spending time in places with high levels of pollution, using addictive substances. Which habit has Emma written in the wrong place?

To answer this question, let’s look at each habit in the table and assess whether it is in the correct place. We will start with the good habits.

Let’s start by considering if taking regular exercise, like running, is a good habit for the nervous system. Taking regular exercise helps to keep nerve tissue healthy, stimulate the growth of new nerve cells, and promote the growth of capillaries, which bring oxygen to the brain cells. So, exercising regularly is in the correct place because it is a good habit.

Next, let’s consider if using tranquillizers or stimulants is a good habit for the nervous system. Taking tranquillizers, such as certain drugs, can cause slower reactions, sleepiness, and trouble focussing. Taking stimulants, like coffee, can cause sleeplessness, increased heart rate, and nervous tension. So, using tranquillizers or stimulants is in the wrong place because these are bad habits, not good habits.

Just to be certain, let’s carry on checking to see if all the other habits are in the correct place. Let’s consider if getting plenty of rest, sleeping around eight hours a night is advised, is a good habit for the nervous system. While we sleep, the nervous system can relax and recover from being alert all day, remove toxins that build up during the day, and carry out important communications that it can’t do during the day. So, getting plenty of rest is in the correct place because it is a good habit.

Let’s move on to look at the bad habits now. First, let’s consider whether spending time in places with high levels of pollution, such as near factories, is a bad habit for the nervous system. Pollution can cause inflammation of the brain, disorders of the brain, such as anxiety and depression, and general poor brain health. So, spending time in places with high levels of pollution is in the correct place because it is a bad habit.

Lastly, let’s consider if using addictive substances, like cigarettes and other drugs, is a bad habit for the nervous system. Addictive substances can have negative impacts on memory, learning, and stress levels, which can then cause further problems like sleeplessness and anxiety. So, using addictive substances is in the correct place because it is a bad habit.

So, the habit that is in the wrong place is using tranquillizers and stimulants.
