فَالِقُ الْإِصْبَاحِ وَجَعَلَ اللَّيْلَ سَكَنًا وَالشَّمْسَ وَالْقَمَرَ حُسْبَانًا ذٰلِكَ تَقْدِيرُ الْعَزِيزِ الْعَلِيمِ
He causes the dawn to break; and He has made the night for rest, and the sun and the moon for reckoning; this is an arrangement of the Mighty, the Knowing.
M Shakir's Quran Translation
Spherical Shape of the Earth
The term فالق الاصباح that is breaking the dawn in the Ayat points towards the spherical shape of the earth contrary to what was thought at the time of Prophet Muhammad SAW. There are other Ayats in the Quran where spherical shape is described explicitly. We'll discuss this topic there. (See Surah Shams 91:6)
Ayaats in the Quran which point towards Geo Spherical Shape of the Earth
Surah Anaam 6:96, Surah Hajj 22:6, Surah Luqman 31:29, Surah Faatir 35:13, Surah Hadeed 57:6, Surah Shams 91:6.
Night 'designed' for rest
The second important thing mentioned in the Ayat is that Allah has made the night peaceful, in other words night is specially designed for sleep and rest. Modern Scientific discoveries uncover this secret.
Melatonin
First interesting thing is the discovery of hormone which makes one 'sleepy'. Melatonin is a naturally occurring hormone that is released into the bloodstream during the hours of darkness. While scientists continue to study the function of melatonin in humans, they believe the hormone plays a role in the body's circadian rhythm. This rhythm regulates the physiological functions that occur in the body within a 24-hour period, such as sleep-wake cycles, fluctuations in body temperature, heart rate, and blood pressure.
Scientists theorize that because melatonin levels are low during the day and high at night, melatonin may instruct the body when it is day or night, enabling the body to adapt and meet the demands of its changing environment. Melatonin may also provide seasonal cues by, for instance, informing the body about the longer nights that occur in winter and the shorter nights in summer.
Other studies have found that melatonin levels in the body decline with age in humans, leading some researchers to speculate that melatonin acts as an antiaging hormone by alleviating some of the adverse effects of aging such as heart disease. (Turek, Fred W. "Melatonin." Microsoft Encarta 2007)
The hormone melatonin prepares the body for sleep by slowing down peoples' physical movements, making them sleepy and tired, and functioning as a natural tranquillizer that eases their minds. During sleep, heartbeat and respiration rhythms slow down and blood pressure falls. In the morning, the production of the hormones stops and the body is stimulated to awaken.

Reduced Photosynthesis and perspiration in plants
Many activities that take place during the day slow down and rest during the night. In plants, for instance, perspiration in leaves and photosynthesis begin to rise when the Sun rises. In the afternoon, the situation is reversed. In other words, photosynthesis slows down and respiration increases since perspiration is accelerated as the temperature rises. At night time, as the temperature falls, perspiration slows down and the plant rests. Most plants would die if just one night failed to take place. From that point of view, night means rest and reinvigoration for plants, just as it does for human beings. ("Light, Temperature and Humidity," Texas Agricultural Extension Service)
Reduced Movement even at the molecular level
Another Interesting discovery is that movement even at the molecular level decreases at night. The radiation emitted by the Sun during the day activates the atoms and molecules in Earth's atmosphere and causes them to achieve higher energy levels. As darkness falls, the atoms and molecules fall to lower energy levels and start to give off radiation. ("Night-time on Venus", January 18, 2001)
And We made the night to be a covering
(Surah Naba 78:10)
