Who Is Sun Sensitive?

Your doctor may let you know the possibility of sun sensitivity, but cannot predict which patients will feel it. People can take the same amount of the same medicine. Some people may be fine in the sun, while others will explode and burn.
Vicky Zhen Ren, MD, assistant professor of dermatology at Baylor College of medicine in Houston, said: “the photosensitivity caused by drugs affects everyone, regardless of skin color, but in people with darker skin color, the skin may be milder.”. For example, if your skin is darker, the red seen on lighter skin may be more purple.
The darker your skin, the higher the amount of melanin, a substance that absorbs harmful ultraviolet rays.
Elizabeth Messenger, MD, said: “patients with darker skin color are less likely to have phototoxic side effects, because the more melanin in their skin, the stronger their protection, but there are still risks. Even if the risk is small, everyone should take the same precautions.”, Assistant professor of clinical dermatology, Perelman School of medicine, University of Pennsylvania.

Coronavirus and Your Lungs

Sars-cov-2 is a virus that causes novel coronavirus 19 and belongs to the coronavirus family.
When the virus enters your body, it will contact the mucous membranes of your nose, mouth and eyes. The virus enters healthy cells and uses the cells to make new viral parts. It reproduces and new viruses infect nearby cells.
Think of your respiratory tract as an upside down tree. The trunk is your windpipe or windpipe. It splits into smaller and smaller branches in your lung. At the end of each branch is a small air sac called a alveolus. This is where oxygen enters the blood and carbon dioxide is discharged.
This novel coronavirus can infect the upper or lower respiratory tract. It spreads along your respiratory tract. Lining may be irritated and inflamed. In some cases, the infection can go all the way to the alveoli.
2019 coronavirus disease is a new disease. Scientists are learning about its effects on the lungs every day. They believe that the impact on the body is similar to the other two coronavirus diseases, namely severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (mers).

What we need to know ahout the COVID-19 Delta variant:

What do you know?
It spreads very fast. As of August 4, 2021, delta variants have covered more than 130 countries. In many countries, the number of coronavirus diseases has exceeded α The variation, including the United States, is considered to be 55% to 90% easier to spread than the previous covid-19 variation. Experts believe that the infectivity of the delta is 30% to 100% higher than that of alpha.
Researchers are still not sure why the delta variant is more likely to spread than other variants. They believe that changes in the mutant protein may make it easier to enter human cells. Another early study showed that the mutation of delta variant may help it better fuse with human cells after attaching itself. If it can easily mix with your cells, it can infect more cells and overwhelm your immune system.
It seems to affect young people more often. In the UK, studies have shown that children and adults under the age of 50 are 2.5 times more likely to be infected.
Symptoms seem to be more severe and occur faster. If the patient has delta variation, he is more likely to be hospitalized. Studies have shown that its risk of hospitalization is almost twice that of alpha variation.
In China, doctors say patients with delta mutation are more serious than those they treated in the early stage of the pandemic. Their condition seems to be declining faster.
Zoikovi 2019 coronavirus disease research, an application that allows people to track symptoms, shows that covid-19 symptoms in the UK may change with the spread of delta variants.
The main symptoms reported on the application include:
headache
sore throat
runny nose
fever
Cough is becoming less and less common, and loss of smell is no longer among the top ten common symptoms. The researchers worry that people may mistake the symptoms for a bad cold, so as to avoid isolation and lead to the spread of the mutant virus.
How to protect yourself
Vaccination is your best choice. The report showed that two doses of Pfizer biontech vaccine had 79% protective effect on Delta variant infection. If infected, it seems to have a 96% effect on hospitalization.
Due to delta variation, the success rate of two doses of AstraZeneca vaccine in stopping hospitalization was 92%. No deaths were reported in the vaccinated population.

Standards of children’s mental health

The criteria for determining whether a child is mentally healthy are as follows: good living habits, including diet, sleep, exercise, words and deeds. Some children like to be caressed by their mother when they fall asleep, and some prefer to eat certain snacks. This is also a normal phenomenon in the growth process. It is not a psychological disease. They have a good personality, have a certain self-esteem, self-confidence and self-control ability, have no quirks and bad manners, and can basically maintain a normal personality such as peace, optimism, humility and willingness to help others in their daily life.
The intelligence level of normal intelligence children is different. As long as they basically meet the intelligence development level of this age, they are normal, which can be measured from many aspects such as language, imagination and thinking ability.
Normal psychological quality, without excessive fear, panic and anxiety, happiness, anger, sadness and happiness, lively and generous, respect others, and have a certain adaptability. On the contrary, it often shows excessive fear, hyperactivity disorder, obsessive-compulsive disorder, fox independence, depression and paranoid tendency, indicating that the child’s psychological quality is not good.
Strong curiosity and memory have strong curiosity and memory, especially for what they are interested in, they will be curious, excited and never forget. If a child is indifferent to anything new, then the child’s psychology will have a problem.
Be good at communicating with others, be good at communicating with peers, get along with others equally, friendly and harmoniously in the process of communication, without suspicion, serious jealousy, obvious bullying and bullying.

How does nicotine affect blood sugar?

Nicotine can raise or lower your blood sugar level. This chemical changes the way your body uses glucose, the sugar in your blood that fuels your cells.
It will increase your chances of developing type 2 diabetes and make your diabetes worse. On the other hand, nicotine may cause severe hypoglycemia (hypoglycemia) in people with diabetes and insulin.
insulin resistance
Nicotine will change the chemical process in the cell, so that the cell does not respond to insulin, so as to let insulin enter the cell. This situation is called insulin resistance.
Your cells need insulin so they can extract glucose from your blood and use it for energy. When they can’t, glucose stays in your blood and your blood sugar level rises.
Nicotine also causes the body to produce more triglycerides, a fat associated with insulin resistance. Nicotine increases the level of anti insulin hormones.
What will happen to your body
Smoking soon affects the ability of cells to use insulin. You may show signs of insulin resistance in an hour. Studies show that people with diabetes and smoking need a larger dose of insulin to control blood sugar.
This is a problem because when your blood sugar is too high in a few years, it may lead to heart disease and damage your kidneys, nerves and eyes.
Sources of nicotine
Smoking is the most common way to get nicotine. The more smoking, the greater the likelihood of developing type 2 diabetes. Smokers have a 30% to 40% chance. Smoking more than 20 cigarettes a day almost doubles your chances.
Other ways to get nicotine can also raise your blood sugar:
Passive smoking or second-hand smoke (inhalation of other people’s cigarettes)
Chewing tobacco (dip, pinch, chew)
Nicotine polacrilex
Electronic cigarette (electronic cigarette, exhaust)
Quitting smoking helps
If you gain weight in the first few weeks after you stop using nicotine, your insulin resistance may get worse, but stick to it. By the end of the second month, insulin will begin to play a better role.
If you don’t have diabetes, you may be more likely to get type 2 diabetes after smoking cessation. In the first two years, the chance to get it was the highest. This is usually because you have gained weight, so talk to your doctor about ways to avoid weight gain.
Two years later, the opportunity begins to decline. In 12 years, you will compete with a person who never smokes in a fair environment.
