In the modern society with high pressure and fast pace, "tiredness" seems to be everyone's mantra. But do you know that besides the objective reasons, some bad habits you inadvertently have may also cause you to become tired. Let's have a look. Who are the killers that make your body more and more tired?

01 Not drinking enough water
Even a slight degree of dehydration (only 2% of normal body fluids are missing) can affect energy levels. Dehydration will make the blood more viscous, reducing the efficiency of the heart to deliver oxygen and nutrients to various tissues and organs.
Suggestion: In order to calculate the normal drinking water volume, you can convert the weight into pounds (1 kg ≈ 2.2 pounds), divide it by 2, and multiply it by 28.35 to get the daily milliliters of drinking water needed.

02 Insufficient iron intake
Iron deficiency can affect the flow of oxygen to muscles and cells, resulting in dullness, irritability, weakness and inability to concentrate.
Suggestion: You can eat more lean meat, tofu, eggs, dark green leafy vegetables, nuts, etc. and eat them together with foods rich in vitamin C to increase absorption. In addition, slight magnesium deficiency may also lead to fatigue. Eating some bananas and potatoes every day to supplement magnesium can help convert protein, fat and sugar into energy sources.

03 Like to eat junk food
This can cause blood sugar levels to rise and fall sharply, leading to fatigue.
Suggestion: Eat more high fiber foods rich in complex carbohydrates, such as whole wheat cereals, whole wheat bread and vegetables, to help maintain blood sugar balance. Eat less greasy food and control the amount of saturated fat in the diet within 10%.

04 Eating unhealthy breakfast
A good breakfast can stimulate your metabolism and make you have enough energy for a whole day. If you don't eat breakfast, you will feel lazy.
Suggestion: A rich breakfast should include whole grains, protein, fruits and healthy fats.

05 No more exercise when tired
This would be counterproductive. The study found that healthy adults who are used to sitting for a long time take exercise for 20 minutes three times a week. After six weeks, they no longer feel tired, but have more energy. Regular exercise can enhance physical strength and endurance, and help the cardiovascular system deliver oxygen and nutrients to all parts of the body.
Suggestion: Almost all activities can help relieve fatigue, such as singing, deep breathing, walking, etc. When you really can't lift your strength, you can lie down and put the pillow under your feet, so that your feet are slightly higher than your head, which can make the blood flow to your head, so as to keep awake.

06 Stay up late at weekends
This can lead to difficulty sleeping on Sunday nights and not getting up on Monday mornings.
Suggestion: Get up at a fixed time on weekends. If you want to take a nap, do not take more than half an hour, otherwise you will be more tired after waking up.

07 Lying in bed playing with mobile phones
The blue light from the display screen of tablet computers, smartphones, etc. will inhibit the secretion of melatonin, disrupt the natural physiological rhythm of the human body, and cause fatigue.
Suggestion: Shut down at least half an hour before going to bed.

08 Have a drink before going to bed
Alcohol can reduce blood sugar content, inhibit central nervous system, produce sedative effect, and finally disturb sleep. This is because alcohol in the metabolic process will cause adrenal gland secretion disorder, so that drinkers can easily wake up at night.
Suggestion: Do not drink alcohol within 3-4 hours before going to bed.

09 Easy to worry about trifles
If you always feel that bad things are going to happen, you will be troubled by anxiety. This psychological dilemma will make people physically and mentally exhausted.
Suggestion: Take a deep breath when you are anxious, and then ask yourself how likely the worst thing is to happen. Or go outdoors and discuss this issue with your friends, which will help you cope with reality better.

10 Don't know how to refuse others
Always meeting the excessive requirements of others will make you pay for your physical strength and happiness. What's worse, it will lead to anger and resentment over time.
Suggestion: Say "no" to things you don't like at the right time, and don't try to be brave when encountering unsatisfied requests.

11Everything is perfect
Irene Levin, a psychiatry professor at New York University School of Medicine, believes that striving for perfection will make work more difficult and work longer.
Suggestion: limit the time for completing the work and strictly follow the plan. After a period of time, you will realize that the extra time will not actually improve your work.

12. The desk is messy
A cluttered desk will distract people and limit the ability of the brain to process information.
Suggestion: Sort out the documents according to the work habits, and tidy them up in an orderly manner, which helps to cope with the work with a positive attitude.

The dike of thousands of miles was destroyed by the ant nest, which is also true for human health. Any serious illness is caused by carelessness in details of daily life. Therefore, to protect your physical and mental health, you must pay attention to details and attach importance to every little thing in life. With good living habits, health will be guaranteed.
