With the mapping of the human genome, geneticists are able to
identify key protein sequences that can indicate major traits in a
person. This scientific breakthrough is helping scientists provide
proper medical therapies to patients seeking help with numerous
physiological issues.
In this day and age, two of the most important health issues, lacking exercise and poor quality of sleep, are hurting millions of Americans and people around the world. These devastating lifestyle choices can afflict horrible damage on the human body. However, geneticists are finding out how genes are a major influence over a person's lack of exercise or poor sleep.
How Genes Affect Exercise
We all know that exercise is extremely beneficial to the human body. However, for some people it does not seem any amount of physical activity seems to influence their weight. Geneticists have found that there are genes that influence how the human body processes fat. For some people, these genes are able to more efficiently process fat during the consumption process. For others, however, their genes seem to store fat more frequently, causing these people to gain weight.
Scientists at Duke University have concluded that about 50-70% of a person's body weight can be determined by their gene's influence on body behavior. This was verified by European researchers studying identical and fraternal twin behavior, showing that about 60% of our exercise behavior is a result of our genetic makeup. That means there is wiggle room for personal behavior to alter how bodies may process fat.
New studies have even showed how pushing exercise can actually alter genes. 23 relatively healthy, but overweight patients were analyzed in a peer-reviewed study where these patients were told to participate in aerobic exercise classes every week. After 6 months, the scientists found the genetic code in the patients' fat cells had actually changed by 35% compared to their previous code makeup. In theory, this showed that the body could change how it genetically processed fat and sugars based upon the amount of exercise an individual does per week.
How Genes Affect Sleep
Sleep is a very complex bodily reaction between the brain and the body. We all know that without sleep, our health would deteriorate. Sleep conditions like narcolepsy and fatal familial insomnia disorder, geneticists are eager to study how the genetic code influences brain chemistry related to sleep.
What most geneticists have found is that a person's sleep hygiene (how much they sleep, when they want to sleep, etc.) are determined by genetic factors. The circadian rhythm, the biological clock for all animals, varies in its relative preference for humans (such as wanting to go to bed at 10 PM instead of 12 AM). This even affects how fatigued a person is after some hours of sleep. For example, some people function better with 7 hours of sleep instead of 8 hours of sleep.
Like exercise, a person's sleep hygiene is also influenced by lifestyle. A study conducted in Britain found that putting human beings on a 28 hour circadian rhythm instead of a 24 circadian rhythm influenced the behavior of over a third of a patient's genetic code. The study verified fears many scientists have over third shift workers or long-shift workers are more susceptible to various health problems, such as heart disease and high blood pressure. The sleep studies show that because the genes cannot process proteins properly when the body is not on the circadian rhythm mandated by the genetic code, then people's bodies react negatively. These effects will differ based a person's genetic code as well. For example, a person who upsets their circadian rhythm regularly may be fatigued and lethargic after sleeping versus another person who may have cognitive difficulties after sleeping.
Conclusion: Genes Control and Are Affected By Behavior
When it comes to very important health processes, like exercise and sleep, some genes control how a person can handle and manage exercise or sleep. Lifestyle choices can also influence those genes themselves, improving how proteins in the genetic code are processed, improves human health.
