The purpose of the study is to understand how blood pressure, heart rate, and symptoms of low blood pressure (such as dizziness or nausea) are affected by positional changes and exercise when on land or in the water for people who tend to experience orthostatic hypotension.

Participants will be asked to sit and stand multiple times (before, immediately after, and 2 hours after a 15-minute walking session). The walking session will consist of 3 minutes of walking at a light intensity followed by 9 min of walking at a moderate intensity and a 3-minute cool down walking at a light intensity. This walking session will occur in a pool.

Systolic blood pressure (mmHg)
Blood pressure will be taken with an automated blood pressure device
Time frame: <1 minute upon standing
Diastolic blood pressure (mmHg)
Blood pressure will be taken with an automated blood pressure device
Time frame: <1 minute upon standing
Self-reported orthostatic hypotension symptoms
A self-reported instrument assessing symptoms from low blood pressure experienced upon standing or after prolonged upright activities. Possible scores range from 0 (no symptoms) to 10 (worse possible symptoms)
Time frame: 2 minutes
