Solution
Understanding Sleep Stages
The first stage of sleep in the sleep cycle is known as Light Sleep. This stage occurs when you first start to fall asleep and your brain transitions from wakefulness to sleep.
- During this stage, the body experiences a decrease in muscle activity and a drop in heart rate and body temperature. It’s also quite easy to wake someone in light sleep.
Summary of Sleep Stages
- Light Sleep: The initial stage where relaxation occurs, making it easy to be awakened.
- Deep Sleep: This follows light sleep, characterized by slower brain waves and is crucial for rest.
- REM Sleep: The final stage known for rapid eye movement and dreaming, playing a significant role in cognitive functions.

Therefore, the correct answer is Light Sleep.
