Step 1
Negative impact of lack of sleep on physical health
Answer
A lack of sleep can increase the risk of several health issues, such as:
- Heart disease: Inadequate sleep can lead to increased stress levels and, consequently, heightened heart rates, which can elevate the risk of heart conditions.
- High blood pressure: Sleep deprivation is associated with a higher likelihood of hypertension, as the body struggles to regulate blood pressure effectively during periods of inadequate rest.
Step 2
Explanation of why adequate sleep is required
Answer
Adequate sleep is crucial for the body to recover and replenish from the day’s activities. Sleep is a time when the body engages in vital processes like muscle repair, immune function restoration, and memory consolidation. Thus, without sufficient sleep, the body cannot properly recuperate, leading to long-term physical health deterioration.
