We have just gone through daylight savings time. Are you still feeling tired this morning? I am.
Anyhow, do some research on how time changes can affect the human body physiologically, psychologically, and chemically. Describe what can be done to make adjustments for these time changes, (supplements, diet, etc.)
You will need to find at least two sources from which you derived your information. Please post their links in your comments. You must also write these two paragraphs IN YOUR OWN WORDS. Failure to write in your own words and failure to post your sources will AMOUNT TO A ZERO OUT OF 100.

Daylight savings time affects our body mentally because we need to adjust to the new time slot. We have to wake up earlier than what we were used to so our minds need to adjust. According to Roenneberg a German scientist, our circadian clock (the body's internal clock) does not adjust to the hours but to the sunlight. Roenneberg added that during winter our body tracks down to sleep which is interrupted during March.
ReplyDeleteOur body is affected chemically because of the time we eat our meals. We have to eat later than usual. Which makes us hungrier and eat more food. We eat non-nutritional food in between meals like chips that are not healthy for us, and we eat a lot more food than our regular diet because of the time change.

Melatonin is a hormone produced in the pineal gland that helps regulate sleep and wake cycles. Your body and its own internal clock that helps regulate your natural cycles of sleeping and waking hours in part by controlling the production of melatonin. Normally, melatonin levels begin to rise int he mid- to late evening, remain high for most of the night, and then decline in the early morning hours. Natural melatonin production is partly affected by light. during the shorter days of winter months, melatonin production may start earlier, or later. Natural melatonin levels decline gradually with age. Some older adults produce very small amounts of melatonin or none at all.
ReplyDeleteThe synthesis and release of melatonin are stimulated by darkness and suppressed by light, suggesting the involvement of melatonin in circadian rhythm and regulation of diverse body functions. Levels of melatonin in the blood are highest prior to bedtime. Melatonin may help our bodies know when it's time to go to sleep and when it's time to wake up. The circadian rhythm is an internal 24-hour time-keeping system that plays a critical role in determining when we fall asleep and when we wake up.

ReplyDeletedaylights saving time aka (DST) has many effects on the body physically. In the first week of DST heart attack rate increases by 5 percent. It also ruins sleep patterns. psychologically it causes Car accidents to decrease. chemically the body gets in tune through chemical reactions witch gets are body's energized in the morning and slows them down at night. DST screws this up and makes it easier to get disease.

Our body clock is a very powerful thing. Melatonin is a natural occuring hormone found in humans. This is produced by the pineal gland. Melatonin may help our bodies know when it's time to go to sleep and when it's time to wake up. it also helps regulate other hormones and maintains the bodies circadian rythm. The circadian rhythm is an internal 24-hour time-keeping system that plays a critical role in determining when we fall asleep and when we wake up. arkness stimulates the production of melatonin while light supresses its activity. Exposure to excessive light in the evening or too little light during the day can disrupt the bodies normal melatonin cycle. You can also take doses of melatonin through pills. They are available as over the counter drugs, not percriptions.

Daylight is a drag because we have to force ourselves on a new sleep cycle. Now that daylight savings is here we go to sleep early and wake up earlier, forcing little sleep. Lack of sleep can effect our body physiologically, psychologically, and chemically. Chemically our body neurotransmitters get our of balance, causing psychologically effects such as, lack of concentration, anxiety, and lack of energy. The physiologically symptoms is blurred vision, nausea,and dark circles under the eyes. psychologically some people become depressed. The only thing we need is time to adjust to this new sleep cycle.

Daylight savings time can really get depressing. Its hard adjusting to the new time. Going to sleep and getting up from bed can be difficult for some. You have to adjust your eating habits too. There might be times where you don't feel like eating something but you have too in order to stay active.
