Why is air quality worse at night? During the day, the sun heats the ground, causing warm air to rise and mix with the atmosphere, which helps to disperse pollutants. But at night, the ground cools down, and this leads to a temperature inversion.
The miasma theory (also called the miasmatic theory) is an abandoned medical theory that held that diseases—such as cholera, chlamydia, or the Black Death—were caused by a miasma (μίασμα, Ancient Greek for 'pollution'), a noxious form of "bad air", also known as night air.
We rely a lot on our sense of sight. When we can't see things clearly we start to wonder if some of the things we can't see can be of harm to us. that leads to us being more alert and paranoid, and in a lot of the cases, more easily scared.

The antidote for belladonna poisoning is Physostigmine, which is the same as for atropine 1. Physosigmine crosses the blood-brain barrier and reversibly inhibits anticholinesterase.
Most of the time, I see fear of the dark start to appear around 2-2.5 years or older. As a toddler's imagination begins to really develop rapidly between 2 and 3 years old, the line between fantasy and reality is blurred, and this is when we see the first fears of the dark begin.

This theory is centered around the bad air or miasma, the unpleasant surrounding. Greco-Roman physician Galen (c. 130-201 C.E.) expanded upon the theory of bad air by tracing how much the presence of bad air would harm the human body and concluded the cause of any diseases is the corruption of air (Sterner, 2).
The demonic theory: According to this theory, the disease is a result of being possessed by demons, or evil spirits.
Although many Medieval doctors continued to believe in the theory of the four humours, they also said disease was caused by demons, sin, bad smells, astrology and the stars, stagnant water, the Jewish people etc.
A miasma (plural: miasmata) was bad air that was believed to be filled with harmful fumes. Both Hippocrates and Galen had written about miasmata, which they said came from swamps, corpses and other rotting matter.
Jasmine flower buds are actually more fragrant than the petals themselves! The buds begin flowering during spring or summer. A jasmine plant's smell is stronger at night because the drop in temperature causes the flowers to open up more.

It's called aconitine, and it's a natural defense mechanism made by the aconite plant, also called monkshood for the shape of its flowers. For its effects, aconite is called wolfsbane, dogsbane and even, disturbingly enough, wifesbane.
