Objectives

• Stress such as Physical exercise Cold stress
  increases blood pressure

4
What is Blood Pressure?

• Simply defined as the force of the blood against
  the walls of the artery
• Expressed as a ratio (120/80)
• Higher number is systolic pressure
• Lower number is diastolic pressure

5
Systolic vs. Diastolic Blood Pressure

• The top number in a blood pressure reading.
• The force of blood in the arteries as the heart
  beats.
• Normal and high systolic reading is also known as
  Isolated Systolic Hypertension or I.S.H.

• The bottom number in a blood pressure reading.
• The force of blood in the arteries as the heart
  relaxes between beats.
• This pressure has consequences when elevated,
  especially for younger people.

Experiment

• Procedure
• The students were introduced to physical stress
  by running up and down the stairs of a 4-story
  building two times.
• The students were also introduced to cold stress
  by submerging their left hand into ice cold
  water.
• Immediately after stress induction, the students
  had their blood pressure taken to observe the
  effects of both types of stress on the flow of
  blood.

Data Collected

Hypothesis

• H0 no matter what happened, blood pressure
  should stay the same.
• Ha physical stress and cold stress would
  increase blood pressure

Result of Paired t-testICE Cold Water
H0 BP before BP after Ha BP after gt BP before
p-value 0.000009 Significant level 5 p-value
lt significant level So, reject H0.
Therefore, under cold stress, one will increase
systolic of blood pressure.

• Similarly, our data supports the other three
  paired t tests which are
• normal diastolic vs. cold stress diastolic
• normal diastolic vs. physical stress diastolic
• Normal systolic vs. physical stress systolic

12
Conclusion Manage Stress

• Under any kind of stress, blood pressure will
  increase.
• One should develop relaxation techniques to deal
  with stress.
• To get a healthy life, one should control his/her
  blood pressure by managing stress.
