Sleep deprivation drastically affects our body's ability to metabolize glucose, leading to symptoms that mimic early-stage diabetes. We will have trouble in thinking properly and we will be putting on weight, and we will have road rage incidents frequently because of lack of sufficient sleep.

Inadequate sleep is the cause of many vehicle accidents because our brain's frontal cortex relies on sleep to function effectively. Insufficient rest adversely affects the frontal cortex's ability to control speech, access memory, and solve problems, whether those problems are lane changes or complex issues at work.

Healthy people who start skimping on sleep quickly show symptoms of ageing and early diabetes, as their glucose metabolism falls by up to forty percent, which will cause weight gain.When healthy people get sufficient sleep, seven to nine hours for most adults, the above physical reactions will disappear and they will get their energy back.

We must avoid late-night snacks, particularly if they are high in sugars and starches. They will raise our blood sugar levels, making it hard to get to sleep. Later in the night, those levels will fall, which will keep us awake. We must eat a high-protein snack several hours before going to bed. High-protein snacks like low-fat cheese will provide the L-tryptophan we need to produce melatonin and serotonin. With our high-protein snack, we may eat small pieces of some fruits such as apple. Fruit sugar helps the tryptophan cross the blood-brain barrier.We must not eat foods such as dairy and wheat products because they affect sleep, sometimes causing apnea, excess congestion, gastrointestinal upset, and gas.

We must make our bedroom as dark as possible at night. Even a little light creeping into the room can throw off our circadian rhythm and our pineal gland's production of melatonin and serotonin, which help us to you sleep. This applies to the toilet also and we may use a night-lamp in the toilet. We must not watch television before bedtime, which will stimulate our brain, making it hard for us to fall asleep. It also disrupts our pineal gland due to the bright light from the television.

We must not keep the alarm clock or watch or mobile phone near our bed, because waking up and seeing the time will stress us.
