Hoping that artificial tanning will make them look more fit and healthy, people get to ridiculous measures sometimes. Once sunless sprays were quite popular, and pale people were sometimes seen with patches of their skin unevenly sprayed with self-tanners. Today there is no need for such dilettante tricks as people can simply lie under the tanning lamps to get a swarthy skin. Nevertheless, not all skin types can accept such an exposure positively.
Prolonged exposure to the sun has the direct risk of damaging one’s skin. Tan is the reaction of the body that tries to accept fewer sun rays producing the brown pigment melanin. Dark-skinned and swarthy by nature people can accept more sunlight without damaging their skin, which does not refer to pale people. The latter are more prone to premature aging or getting skin cancer due to the change sun rays cause inside skin cells. That is why fair-skinned people who overuse natural or artificial tan often have flabby or worn-out skin that does not look glowing in any way.
Skin cancer is the main disease linked to sun rays. Being the largest organ of our body, skin perceives everything we apply to it, including the sun, and reacts to the damage respectively. Every doctor would advise their patients with pale skin to cover it with clothing in summer when the radiation is excessive. There are also plenty of sunscreens that allow us to protect skin while bathing. They also work well and protect skin effectively when applied correctly.

Comments Off on What are some common sleep disorders and how are they treated?, Disease, Health, by admin.

Inability to fall asleep and wake up in the morning is quite a problem for many people. When the time for a rest is very limited, it is essential to let our body recharge batteries efficiently in these scarce hours. The most common sleep disorders are insomnia, sleep apnea, restless legs syndrome, and narcolepsy. Neither of them is particularly dangerous, but getting little sleep may have quite fatal consequences while driving or doing work.
People with insomnia have difficulties falling asleep or wake up repeatedly in the night. They may wake up too early in the morning and feel as if they never slept at all. The productivity of people with insomnia is miserable as their body is not ready to work after a restless night. There are countless causes of why insomnia arises that range from our habits to chemical imbalance. It is essential to find out why every particular patient cannot fall asleep to remove the stressor.
Sleep apnea is a disturbance in our breathing patterns. If our soft tissue blocks the airways we can lie breathless for a while. The same happens when our brain does not send the signal for breathing in sleep. Behind the apnea stand some chronic conditions that cause swelling of the nasal tissue or neural disorders that put blocks to breathing. Treating these issues will solve the problem for people who cannot breathe while asleep.
Narcolepsy is rather a state than a disease. It is characterized by excessive sleeplessness in the daytime and falling asleep in the period of activity. Though often undiagnosed, narcolepsy is likely to be the consequence of disturbed chemical interchange inside the body. Patients shall better check their thyroid hormones and have recommendations according to their diet.

What technologies are available to home owners to help them conserve energy?

Comments Off on What technologies are available to home owners to help them conserve energy?, Green energy, Technology, by admin.

Despite the rapid development of technology, it is rather a wealthy household that is equipped with the smartest household appliances. An average homeowner still needs to take a good care of their resources not to pay extra dollars in bills. But today we already have some technological advancements accessible to an average household. Some of them are not very smart, the others, on the contrary, quite exciting.
Programmable thermostats are the simplest and cheapest way to save energy. Most heating devices are supplied with a thermostat, but it is not a problem to buy one in a retail shop and apply it to an older heater. We just install the lowest comfortable temperature on the device and stop heating rooms when we are not at home. As simple as that we can save $200 per year without investing any additional costs in smart devices.
Solar panels cost a lot, but still, they are available and very popular on the market. They are a reasonable long-term investment so that people who do not move every now and then are quite interested in changing their energy supplier. Eco-efficiency of solar panels is their greatest benefit, and those who choose to produce electricity themselves can get a tax reduction. But in terms of energy, it is even more important not to depend on external suppliers.
If an average American home is not very smart yet, it can easily become so in a few years. There are numerous apps able to control smart devices, prevent leaks, and put them off whenever the owner forgot to do so. As more smart appliances arrive at our home, we will be able to control them remotely and save energy every time.

In what ways do Walmart stores affect local economies?

Comments Off on In what ways do Walmart stores affect local economies?, Economics, Finance, by admin.

As the struggle between large and small retailers exacerbates, we constantly hear about the assault of multinational corporations. Walmart recently became the talk of the town as small local businesses cannot compete with the global retailer showing in their area. First, Walmart offers lower prices on common groceries, and next, it undercuts prices even more as small businesses make attempt to compete. Walmart may look like an efficient enterprise for stakeholders but it is not the same positive for local economies.
The greatest loss applied to Walmart stores so far concerns sales redistribution. Local stores get closed and consumers start buying products that are cheaper than their local ones. The redistribution in sales equals $25 million annually and the local population is $600,000 short in wages over the same period. Practically, the retail chain is known to drain local industries of money that would otherwise circulate inside the local community.
On the bright side, Walmart brings positive effects to the communities with the unsatisfied demand. If local businesses could not supply enough groceries, someone still has to do that. But giant retailers may go as abruptly as they came, and the rural economy will be left in the vacuum then. In 2016, the company announced closing more than 200 stores across the US, a half of them situated in rural areas. As the result, many towns will remain without the only grocery store and pharmacy in the area. Globalization of remote places is always a good idea but only when it happens from within the community. Large retailers that come and go not only drain finances from the area but prevent its further independent development.

What are the effects of prolonged steroid use on the human body?

Comments Off on What are the effects of prolonged steroid use on the human body?, Drug abuse, Health, by admin.

Anabolic-androgen steroids are synthetic derivatives of testosterone used to enhance muscle growth. They also reduce muscle damage and stimulate recovery after the workouts, which are essential processes to athletes. Steroids belong to performance-enhancing drugs, and many organizations prohibit their use. Nevertheless, athletes keep taking steroids for a long time before the big event to get stronger and more resilient.
Steroids help to build strong muscles quickly but other effects come along. An increase of testosterone causes acne, fatigue, and mood swings. Decreased appetite and sleeping disorders make it difficult to be productive. Disturbed metabolism does not allow people to function properly unless they take another portion of the drug. That is how steroid addiction develops.
Long-term effects of anabolic steroids are even more worrisome. Though testosterone does not trigger an immediate response in the brain, the production of neurotransmitters is clearly disturbed over the time. Mood swings transform into lasting aggression that drags paranoia and delusion. Women develop baldness and experience growth of excessive body hair. Men face enlarged breasts and decreased sperm production. Due to the prolonged intake of hormones, these effects are irreversible.
Cardiovascular system and liver are heavily distressed by the excessive intake of synthetic hormones. The human body has a certain physical resource, and high performance has its costs. Heart attack and stroke may happen even to young athletes who overuse steroids. The disturbed balance of lipoproteins drags atherosclerosis, and there are high chances of developing clots. The liver cannot stand high concentrations of synthetic hormones either and it may develop tumors.
