Answer:

Sleep is essential for good health. In fact, we need sleep to survive — just like we need food and water. So, it’s no wonder we spend about one-third of our lives sleeping.

Many biological processes happen during sleep:

1.The brain stores new information and gets rid of toxic waste.

2.Nerve cells communicate and reorganize, which supports healthy brain function.

3.The body repairs cells, restores energy, and releases molecules like hormones and proteins.

These processes are critical for our overall health. Without them, our bodies can’t function correctly

Explanation:

According to the energy conservation theory, we need sleep to conserve energy. Sleeping allows us to reduce our caloric needs by spending part of our time functioning at a lower metabolism.
