About Sleep Length

Sleep is an essential part of our lives. It helps us recover from everyday activities and maintain our mental balance. The optimal length of sleep varies by age group - healthy adults need 7 to 9 hours of sleep per night, while children and older individuals need more.

‍

What causes shorter sleep length?

Stress, hormonal changes, shift work, excessive sleeping/day sleeping and irregular sleeping habits can all negatively affect the length and quality of your sleep. If you regularly sleep less than six hours but feel rested and your daytime functioning is not disrupted, it may be due to a condition called 'short sleep syndrome' (SSS).

• However, if your sleep is too short and negatively affects your daily functioning, you should try to follow a regular sleep schedule, avoid stimulants (for example coffee) for several hours before bedtime, avoid daytime sleep and use your bed only for its intended activities.
• Maintain good sleep hygiene, which you can read more about on Macromo Insider.
