## Step 1The question is asking about the physiological changes that occur during the first stage of sleep. This stage is also known as light sleep or non-REM sleep.## Step 2During this stage, the body undergoes several changes to prepare for rest. These changes include a slowing down of the heart rate and respiration rate.## Step 3The slowing down of the heart rate and respiration rate is a natural response of the body to prepare for rest. This is because the body is transitioning from a state of alertness to a state of rest.## Step 4Therefore, the correct answer is the one that states that both the respiration and heartbeat slow down.
