How do different colors affect the blood pressure?

How does the sight of the colors red, blue, yellow, orange and green affect the blood pressure on females in a range of age of 17-18 years old?

Blood is carried from the heart to all parts of the body through arteries. Blood pressure is “the force of blood against the arteries”. It is “composed” of two other pressures, the systolic anddiastolic pressures. When there’s a heartbeat the blood is being pumped out into the arteries, the blood pressure here is at its maximum and it’s called the systolic pressure. Between each heartbeat the heart is at rest and the blood pressure decreases, this is the diastolic pressure..
The BP can be affected by many external factors such as health habits, meals, exercise, gender, age and emotionsamong others. The fact that color would be treated here as the factor that affects the blood pressure is because we are constantly surrounded by colors, and the influence this can have on a person’s mood and therefore their blood pressure is huge. The colors are directly connected to the emotions, each color means something and transmitters a feeling. Emotions play a big role in our daily life andconsequentially in blood pressure.

AIM
To observe the effects looking at the colors red, blue, yellow, orange and green has on the blood pressure in females in a range of age of 17-18 years old.

MATERIALS
* Stopwatch
* 5 females
* Dark room
* Sensor for blood pressure
* Computer
* Colors (red, blue, yellow, orange and green)
* Chair


VARIABLES
*Independent: colors (specifically red, blue, orange, yellow and green)
* Dependent: Blood pressure
* Controlled:
1. Dark Room A room with blackout (audiovisuals room) so light won’t enter and the subject’s exanimated will only concentrate on the color that’s provided.
2. Gender the subjects that will be exanimated will be the same gender, in this case female.
3. Age The femaleswill be selected from range of age already stipulated. (17-18). Since the BP is different depending on the age, for women after the menopause the BP is likely to have increased.
4. Time of the day the experiment will be done all in the same day, during a period of time, which would be the morning. Due to the fact that studies have shown that the highest blood pressure reading will probablytake place around noon and the lowest around 3 to 4 a.m.
5. Position The position would be seated through the whole experiment, from the first register of blood pressure to the last. Is the position is change its more likely that the person feels more exhausted or more relax therefore the blood pressure may vary.
6. Time looking at each color and resting between each color

METHOD
1.On a power point presentation prepare 5 slides each with one of the colors you are going to work with. (Make sure the color fits the whole screen)
2. Place this computer in a dark room. (Preferably a room that has blackout so light wont enter.)
3. Ask for 5 females between the ages of 17 to 18 to be the subject’s exanimated.
4. Get female 1 and take her inside the room (remember tohave the light on).
5. Sit her in the chair provided, make sure it is comfortable, legs are uncrossed, back and arms supported.
6. Take her blood pressure (this is her initial BP).
7. Write down the blood pressure.
8. Turn off the lights.
9. Start the power point presentation and let her stare at the first slide (with the first color) for 3 minutes.
10. After these 3minutes take her blood pressure again and write it down.
11. Turn on the light and let her rest for 2 minutes so her blood pressure stabilizes.
12. Take her blood pressure again and write it down.
13. Turn off the lights and change the slide to the other color, wait 3 minutes and take her blood pressure.
14. Do steps 6,7 and 8 for each color.
15. Repeat the method with the same...
